The AC unit, air handler, and furnace are familiar parts of your HVAC system. However, the control board isn’t something you often interact with. If it’s not working, it can’t command any part of your heating or cooling system to operate correctly. We’ll explain what it is, how it works, and what to do if there’s no power to the HVAC control board.
The control board is essentially the system’s command center. Input from the thermostat is received by the board, which then relays the appropriate commands to your furnace or air conditioner. A furnace circuit board regulates the ignition, gas valves, flame sensor, blower motor, and other components. A defrost control board works similarly, except it monitors for the buildup of ice and triggers the defrost function when it’s needed.
First, you’ll need your furnace’s manual, which should show the location and setup of the control board. Before starting, you’ll also need a screwdriver, electrical tape, and a voltage meter. Proceed with the following steps if there’s no power to the HVAC control board:
If the control board isn’t working, there may be issues with temperature regulation. The symptoms are often similar to those associated with other problems, such as blower fan, power, or filter issues. If your HVAC has warning lights or diagnostic codes, you might see a notification of an unpowered or failing control board. However, the system may not work at all if the control board isn’t powered.
The control board should last the life of your HVAC system. But high temperatures, numerous heating and cooling cycles, or wiring issues can wear it out. A single faulty transistor or relay on the board can result in a malfunction. Sometimes a faulty transformer or fuse is the cause; a technician can provide replacement components to fix the problem. If the board is damaged, usually the only option is to replace it, which requires a professional to handle wiring and installation work.
Customers throughout Southern California rely on NexGen for all types of heating and AC repair. If you have temperature control, airflow, or power problem or need an HVAC control board replaced, our licensed technicians will get your system running again in no time. They are fully licensed and insured. You can reach us 24/7 by calling (833) 729-9735.
According to the American Lung Association, you breathe in about 2,000 gallons of air per day.¹ Considering all the pollutants that may be present, that means there’s ample opportunity to inhale dust, pollen, smoke particles, chemicals, and volatile organic compounds. Bacteria and viruses abound in indoor air as well. It may be hard to keep all these out, but investing in an efficient indoor air quality system can improve your comfort and well-being.
Indoor air quality (IAQ) improvements have become a government priority, so they should be on your list as well. The American Rescue Plan, enacted in 2021, included many COVID-19 initiatives and set aside federal funds for indoor air quality improvements in public facilities, schools, and small businesses. But improvements to air filtration and ventilation aren’t only protective pandemic measures. They benefit everyone on a daily basis.
Common IAQ solutions include
Here are a few reasons to consider installing such equipment:
You can breathe voluntarily, but for the most part, you do so automatically. The average adult takes 12 to 18 breaths per minute without thinking about it.² Breathing in polluted air is hard on your body even if you’re not aware of it. Contaminated indoor air forces you to take shallower breaths, which can strain your heart and lungs. Simple exercises and walking up a flight of stairs can become physically tiring.
Ventilating your home and vacuuming regularly aren’t enough to eliminate allergens and other contaminants. Tiny particles that float in the air can cause sneezing, itchy throat, irritated eyes, and congestion. For people with asthma and other respiratory conditions, the effects can be even worse. A high-quality air filtration system can benefit everyone when it’s properly installed and maintained, especially during allergy season.
A good indoor air quality system can balance the humidity in your home. If the air in your home is too humid, it can feel muggy and stuffy. Mold growth is more likely in humid conditions. But not enough moisture in the air can cause dry skin, static shocks, and other issues. The ideal indoor humidity level is around 45%, so there’s a balance between comfort and dry enough conditions to avoid air quality problems.
At NexGen, our indoor air quality solutions can help remove odors. Some odors, such as musty smells from mold or sulfur odors from a gas leak, can be hazardous to your health. Others can put you in a bad mood, increase stress, and make it hard to study or be productive. Traditional filters don’t completely remove odors. However, UV and other specialized filtration systems break down organic materials that cause odors so their sources are eliminated.
With cleaner air, your AC filter will take longer to fill up. Airflow and temperature control are improved. Therefore, improved indoor air quality helps your HVAC system work less hard. You may see noticeable decreases in your utility bill because the unit uses less electricity to keep your home comfortable.
Cleaner air allows for steadier breathing while asleep. Airborne pollutants can not only lead to sleep apnea and other sleep-related breathing problems. They can prevent you from getting the rest needed to replenish your body after a long day. You’ll feel refreshed instead of tired and irritable, which can improve your overall health and well-being.
NexGen provides air conditioning, heating, plumbing, and indoor air quality services in Southern California. We offer the highest quality solutions on the market to remove particulates, mold, and volatile compounds from the air in your home. Our licensed professionals will help you choose products that suit your needs. Financing options are available to help you afford much-needed products and services.

Without a large central AC system, parts of your home may be too hot in summer. Nonetheless, adequate cooling for every room is still possible. A standing AC unit is a convenient option. We will explain the pros and cons of a portable air conditioner, which works similarly to a central air conditioner.
A standing air conditioner can be useful whether you don’t have central AC or it does not serve a particular room. The unit operates on a smaller scale. It draws air from outside through a window, cycles it through a compressor, blows cool air inside, and exhausts hot air outside. All the unit’s working components are contained in a single housing, including coiled tubes that circulate refrigerant. A pipe or air duct allows for an exchange between outdoor and indoor air.
The benefits of using a portable AC include:
Despite their many benefits, stand-alone AC units have disadvantages worth considering. These can include:
NexGen provides a wide range of high-quality HVAC equipment. We’ll help you determine the best system for your Southern California home or business. Traditional, electric, rooftop, and ductless systems are available and we specialize in the latest air purification equipment and thermostats. Our licensed contractors can help install, repair, and maintain your heating and cooling system. For assistance from licensed, insured technicians, book your visit online or call (833) 729-9735.
If your aging air conditioner is acting up, a technician may weigh whether to repair or replace it. Air conditioning repairs can have many benefits. They can restore cooling performance, improve efficiency, and extend the lifespan of your AC. But to decide if more repairs are worth it, consider the following:
Different formulas help determine if an AC repair is worth it. Some experts say to move forward with repairs if the estimate is less than 50% of the cost of replacement. If the estimate is close, don’t be afraid to get a second opinion. Another method is to multiply the age of the unit by the repair cost; replace the AC if the total exceeds $5,000. Multiple repairs in one year can strain your budget. However, if the system only needs occasional repair, it’s worth it.
The age of your AC unit is a major factor in deciding whether to repair or replace it. According to the U.S. Department of Energy, a central air conditioner has a lifespan of 15 to 20 years.¹ In harsher climates, it may last only 10 to 12 years. But AC longevity is affected by many factors, including quality of installation and how well it’s been maintained. If it’s over 10 years old and needs major repairs, consider whether replacement is more affordable.
Annual maintenance and tune-ups can prevent many AC problems. Just by changing the filter every 1 to 3 months, keeping plants and debris away from the outdoor unit, and scheduling minor repairs when necessary, your system can last longer. But if you’ve neglected maintenance, multiple problems may be too expensive to fix.
An air conditioner’s energy efficiency has a significant impact on operating costs. In the Southern U.S., all new ACs must be rated at least 15 SEER (as of January 2023), so having a unit with a 14 to 25 SEER rating aligns with current standards. That means your 12 SEER unit that’s 15 years old costs you more money than necessary (also, consider that operating efficiency declines with age). That means upgrading to a newer, more efficient unit will reduce energy costs.
With the phase-out of R-22, Freon and the systems that run on it are becoming scarcer. Recharging an R-22 system is becoming prohibitively expensive. So is finding replacement parts for one. Therefore, you’re likely better off replacing the system with one that uses R-410A refrigerant, a more environmentally friendly option that can’t be used in older units.
If an outdoor or indoor unit was once replaced separately, the system may have kept working. But an equipment mismatch can shorten its lifespan. At the very least, it will reduce efficiency. Replacing your HVAC with a matched system will improve efficiency and have a wide range of other benefits for years to come.
Think about how comfortable you were before needing an air conditioning repair. Has your home not been cool enough? Have you noticed hot and cool spots at home? Are there humidity issues or are your energy bills getting more expensive? If you’ve answered yes to any of these questions, it’s time to consider replacing the system or updating it to one that supports variable speed technology or zoning.
Even if you could afford another AC repair, what if rebates, tax credits, or other financial incentives can save you more? Manufacturers, utility companies, and local government agencies across the U.S. offer financial incentives for installing high-efficiency equipment. The amount you can save on an air conditioner varies from company to company and region to region. You may save a few hundred or thousands of dollars by replacing your AC.
Whether you base your decision on cost calculations or how your AC is performing, the decision to repair or replace it comes down to your unique situation (unless the system has completely failed). We believe in providing the knowledge to make informed decisions. Air conditioner repairs are worth it for a younger, well-maintained system. But they get more costly as a unit ages along with the overall cost of ownership.
Our experienced technicians provide air conditioning repair services in Southern California. They’re able to fix common issues and ensure your system is more efficient and reliable. But we know sometimes AC repair is not enough. If you’ve had numerous air conditioner repairs and your AC is nearing 20 years old, let’s talk about replacing it. We’re ready to evaluate your system and answer your questions. To get started, call (833) 729-9735 today.

An AC tune-up includes the maintenance needed to improve comfort, reliability, and efficiency. Tune-ups can also help avoid expensive repairs. However, they don’t come cheap. Homeowners often wonder how much the service will cost them. The price depends on the scope of the service and where you live. Let’s look at the possible cost of an AC tune-up.
According to Forbes, a tune-up can cost anywhere from $30 to $300. On average, it costs around $120 to tune up your air conditioner.¹ That’s a small price compared to repairs that can cost thousands of dollars. A tune-up can even help your AC last longer, delaying the need to pay for a replacement unit.
Not every tune-up is the same just as not every air conditioner is the same. The cost of tuning up an AC depends on the following:
Also, note that inspections of your ductwork and ventilation system will cost extra. According to Angi, this can run between $80 and $450.²
You won’t save on performing an AC tune-up yourself. Aside from changing the filter and doing simple cleanings, attempting to replace a fan motor, repair a refrigerant leak, or complete any other type of major repair can result in more damage and void the warranty.
An annual tune-up should be completed in the spring. It will ensure your AC works all summer and can save on energy bills. Schedule additional maintenance throughout the year if your air conditioner is older or has known issues.
A standard tune-up takes about an hour if the system doesn’t need any significant repairs.
Most HVAC contractors include tune-ups in their maintenance packages. They often include air filter replacements and inspections of fan motors, capacitors, and ducts. A technician will also check the thermostat and electrical controls. Checking refrigerant levels helps determine if there is a leak. If necessary, the drainage system is inspected and flushed.
NexGen provides high-quality air conditioning maintenance in Southern California. When it’s time for your annual AC tune-up, you can count on our licensed technicians to ensure your unit is reliable and efficient. Tune-ups help prevent breakdowns, but we’re available 24/7 to help in emergencies. To ensure your AC maintenance needs are met, schedule a tune-up today by calling (833) 729-9735.

According to Angi, installing a new AC unit can cost up to $8,000(based on 2023 data). But installation doesn’t only include connecting and setting up a unit. There are several steps and tasks homeowners often aren’t aware of. This article will explain the process a trained HVAC technician will follow when providing AC installation service.
An AC installer will first inspect your home to identify your needs. Are you replacing an existing unit or relocating your HVAC system? Many newer air conditioners are larger in dimensional size, so the current location of your AC may be unsuitable. Manufacturer guidelines, state laws, and local regulations may dictate equipment placement, clearance, and distance from utility meters.
Plus, the installer will consider your climate and the typical levels of heat and humidity. They’ll also perform an energy audit to look for poor insulation, drafty windows, and other factors that can reduce efficiency. Recommendations on improvements often target ways to maximize an AC’s energy efficiency over time.
The size (capacity) of an HVAC system must be just right. A technician will determine the square footage of your home and consider other factors to identify the cooling power you need. Many people oversize their air conditioners, lowering efficiency and increasing wear and tear. While sizing an AC unit requires extra time, it can pay off in improved comfort, moisture removal, energy efficiency, and fewer repairs.
A reputable contractor will explain options that can provide more efficient cooling. If your AC is well-maintained, it can last 15 to 20 years. During that time, you can save significantly if the system is efficient. Air conditioner efficiencies are rated using the following:
During an AC installation service call is a good time to evaluate ductwork for issues that decrease efficiency. Some considerations include whether the duct system is compatible with or large enough for the new unit. An inspector will also determine if your ductwork needs to be sealed or repaired. If there’s significant dirt and dust buildup, air ducts will be cleaned as well.
The installation crew should call or text their expected arrival time. You’ll speak to the lead installer about the project, the equipment to be installed, and other details. Good communication avoids misunderstandings and costly mistakes. In preparation for your new system, the installers will turn off the electricity and gas supply to your existing HVAC equipment and add protection to floors and furniture. All the tools and equipment they’ll use will be set up.
The refrigerant will be safely recovered and discarded with special machinery. A technician who removes AC refrigerant must be EPA certified to do so. Next, electrical wiring is disconnected from the unit, and then the disconnect box and electric power conduit are replaced. The old condenser unit and indoor evaporator coil, air handler, and copper refrigerant line are carefully removed to make way for new equipment. If necessary, modifications to the plenum will be made.
The pad the outdoor unit sits on is replaced and leveled. The ground below it may need to be leveled too, either by laying a gravel base or pouring a concrete pad. Composite pads are often used as concrete is prone to cracking and shifting and not as resistant to machine vibrations. Thorough preparation is necessary because, after installation, air conditioners can’t be moved or lifted without causing serious damage.
The installation procedure depends on the exact type of air conditioner. The general process during AC installation service is as follows:
If installing a mini-split system, ductwork installation or modification will be skipped. The installation crew will drill one hole in an exterior wall to connect a conduit between the outdoor and indoor units.

Poor insulation or a lack thereof can make your home inefficient. Many older homes aren’t well-insulated and even newer properties can benefit from improvements. An insulation service professional can determine whether you need better insulation, but there are signs it’s time to give one a call.
Turning off lights can save some energy but usually doesn’t make a big difference. If you see a significant increase in your monthly electric bill, poor insulation may be the reason. The attic or crawl space may be the source of the problem. Heat or cold temperatures can affect your home if these areas aren’t properly sealed and insulated.
If your heater runs continuously all winter or your air conditioner runs non-stop all summer, your insulation may need to be updated. Contact a professional if you’re using your heater or AC more than in the past or feel drafts near windows, doors, and other locations.
Poor insulation or air leakage can make your living room chillier or the bedroom stuffier than other parts of your home. The temperature should not fluctuate as you go from room to room. If it does, your home may be losing heat at the top and cold air may be filtering in through lower sections.
When your home isn’t properly insulated, moisture and humidity levels can increase. Existing insulation may be water damaged. You may notice stains on walls and ceilings, damp floors, or moldy smells. These indicate you need an insulation service to have damaged materials replaced.
Pipes in exterior walls or that run outside your home, in the attic, or through the basement should be insulated. If not, they can freeze in winter and burst, causing major water damage. Call a professional to insulate your pipes if they’re exposed. It can save a lot of money later.
Poor or deteriorated insulation can let water in from outside. If water is leaking into the attic, new insulation may be needed. Replacing or improving your insulation can stop water infiltration and prevent mold.
Icicles and ice dams are signs of poor insulation. If your attic isn’t properly insulated, warm air can escape and heat the snow above, forming ice that can damage shingles and siding. Over time, the damage can accumulate and cause your roof to leak.
If your allergy symptoms get worse at home, you likely have dusty or moldy insulation. New insulation blocks out air that has pollen and other allergens. It may help alleviate symptoms such as sneezing, runny nose, stuffiness, coughing, or headache.
Insects, rodents, and other pests use any crack or crevice to seek shelter. Mice, rats, fleas, bedbugs, and other unwanted guests can burrow through insulation and some insects even feed off it. If your home is infested, your insulation may be the reason. Higher-quality insulation prevents them from getting in and finding harborage in warm, soft materials.
If the sounds of traffic, chatty neighbors, and barking dogs disrupt life at home, it may be time to update your insulation. High-quality materials will block noise. Therefore, it won’t distract from indoor activities or disrupt your sleep.
Insulation that’s falling from its source must be replaced. It may appear thin, worn out, or wet. When inspecting insulation, wear gloves, safety goggles, and a face mask, and note the type, its thickness, and whether it’s blocking ventilation. Turn off the circuit breaker and remove outlet covers as well; using a flashlight, determine if any insulation is present.
If your inspection turns up any concerns, contact a professional to schedule an insulation service.

California has endured years of drought, but the past few months have brought one rainstorm after another. Repeated deluges have ended water restrictions for many in Southern California. But the atmospheric rivers that keep pummeling the state can do a number on home HVAC and plumbing systems. We’ll look at a few ways to protect your home from the effects of so much rain.
Water can cause serious damage to your HVAC system. Air conditioners are designed to drain condensation, but their components are extremely sensitive to water exposure. The wind is also a problem as it can blow debris onto and into the condenser unit. Fortunately, there are easy ways to protect the system:
If you haven’t covered the AC unit with plywood for winter, place a plywood sheet over the top. It is effective at shielding the unit from snow and ice. If your area doesn’t see much snow, you can cover the unit with a tarp to shield it from rain and strong winds. Strap the tarp on so it doesn’t blow away. Fitting a metal or plywood cage around the air conditioner is also an option. It protects against flying debris.
Before a storm, trim trees, branches, and shrubs so they can’t fall on the AC unit. You can also plant shrubs nearby to block the wind. Exposed wires should be covered to prevent water exposure and damage from falling objects. The unit should also be anchored to a concrete pad next to a concrete or stone wall, and any loose objects nearby (toys, firewood, outdoor furniture, etc.) should be moved inside.
Thick metal mesh hail guards should be installed before a storm hits. They don’t interfere with the unit’s heating or cooling abilities. And you avoid the unit being riddled with dents, bent fins, or damage to the coils that can prevent it from keeping your home comfortable.
Ironically, your plumbing system, which is designed to carry water, can be heavily damaged by it. Rainstorms pose an especially high risk for drains, as sediment and debris can easily clog them. Underground plumbing is also susceptible to damage by heavy wet soil and standing water. Here are some steps you can take to protect your plumbing:
Excessive rainwater can flood your driveway, yard, or deck and even compromise your home’s foundation. Install drains at low points on your property. And check them often for debris to clear away. Use a wet-dry vacuum to pull out debris if necessary, or install a drain guard to prevent dirt, leaves, rocks, and other items from causing blockages. Also, make sure gutters and downspouts are clear and properly installed.
If your toilet starts gurgling during heavy rain, a drain is likely clogged or backing up. Your toilet may back up if rainwater has gotten into a septic tank. Clogged drains can affect municipal sewer lines as well. When this happens, dirty water can accumulate in drains and cause pipes to crack or burst. If your water looks dirty, tastes coppery, or smells like mildew or something worse, call a plumber right away.
Sump pumps remove water from basements or the lowest part of your home. If you have a sump pump, it should turn on automatically when water reaches a certain level. At least once a year, pour some water into the sump pump basin to make sure it’s working. If it doesn’t turn on, call a plumber to inspect and repair it before the rain arrives. It will save you from a messy cleanup later on.
Whether you need AC repair or a plumber in an emergency, you can count on NexGen for prompt, effective solutions. Recent storms in California have affected many homeowners. Be on the alert for air conditioning or plumbing issues and reach out to us as soon as anything seems awry. We’ll provide repairs, drain cleaning, and inspections and address any mold or indoor air quality issues caused by recent rains. To get started, book your appointment online or call (833) 729-9735.
If you’re looking to cool a room or small space, a portable air conditioner can do the job. It effectively cools the air, circulates it, and removes excess humidity. We’ll now answer the question, “How do portable air conditioners work?” in more detail to help you decide on whether to install one.
A portable AC is typically a single freestanding unit with wheels or casters at the bottom. It has a fan that pulls in hot, humid air from the room. Inside the unit, heat is transferred to refrigerant running through the condenser coils. At the same time, water vapor condenses on the coils, removing humidity. The refrigerant turns into a high-pressure gas that eventually releases the heat that’s absorbed from the air.
Moisture that is collected by the system is removed by emptying an internal water reservoir. But many portable air conditioners have an exhaust hose that vents moisture and heat outside. Depending on the model, it may require a separate window venting kit, or it may direct exhaust through an existing air duct.
Some portable ACs use a single hose that removes warm air and moisture. Others have a dual-hose configuration; one hose pulls in fresh air from outside (to cool the compressor and condenser coils) and the second hose pulls excess warm air and moisture from the unit and releases it outside. A dual-hose unit can often cool a room more quickly without creating negative pressure.
Depending on the model, a portable air conditioner can be remotely controlled, operate in fan mode only, or cool a room to a set temperature. Units with a timer can start or stop depending on the time of day. Other products can dehumidify the air without being set to cool, while others move side to side to help distribute cool air.
The installation requirements will vary depending on the model you purchase. Most units are easy to set up. Just remember to consider the following requirements:
Portable AC units are designed to be vented out a window. This is how portable air conditioners work. Hot air must be vented somewhere; if that’s not a window, a hose can be directed up a chimney or through a hole in the wall. However, it’s not recommended to change the length of the hose, as it’s designed specifically for that machine (doing so can overheat the unit or void the warranty). If you must run the hose through a sliding glass door, purchase an extension kit suited for the model and use styrofoam or plywood to fill the void around the hose.
The drainage method depends on the unit. If you have a self-evaporative, portable AC, moisture will evaporate out of the exhaust hose. Some systems have a gravity drain that eliminates water that’s pulled down and out of the unit by gravity. A condensate pump can be used to collect water so you can dispose of it. If your portable unit has a collection tank, it will collect moisture inside. To empty it, turn off the AC, remove the collection bucket, and empty it before placing it back in the unit.
Maintaining a portable AC is simple and can help it work better and last longer. First, unplug the unit to eliminate any shock or fire hazards. Then follow these tips to care for your portable cooling system:
A portable air conditioner can be a convenient and effective way to stay cool, depending on your needs. It’ll cool a room and vent heat and moisture out a window when properly installed and maintained. However, it’s just one of many options for cooling a home or office. NexGen provides professional air conditioning services in Southern California and high-quality central, window, and packaged units as well as ductless mini-split equipment and heat pumps.
Our licensed technicians help install, repair and maintain all system components. They can also provide advice on the right type and size of the system for you. Our team will fully explain all your options. If you have additional questions or want to schedule service, call NexGen at 833-729-9735 today.
An air conditioner provides cool air. A furnace or heat pump keeps you warm and cozy. But it’s the thermostat that’s responsible for ensuring your comfort. Your home will quickly become unpleasant if it’s not working. One of the most common reasons for this is the unit isn’t receiving power. Below, we’ll explain what to do if there’s no power coming to your thermostat (many of these issues are easy to fix).
If someone accidentally turned the thermostat off, your HVAC system won’t receive any signals to run. It’s not infeasible to brush against something and push a switch. If your thermostat has a touchscreen, it’s even easier to make a mistake. Take steps to turn the unit on and see if it lights up and your heating or cooling system kicks in.
If you have a battery-operated thermostat and haven’t changed the batteries in a while, there’s no immediate cause for panic if it stops working. The controls and the display won’t have power if the battery is drained. Changing the batteries is simple. Remove the cover and refer to the user manual and symbols in the battery casing to properly insert the batteries.
Another simple reason no power is coming to the thermostat is it’s dirty. Dirt, dust, and virtually any other buildup can prevent it from working. Wipe down the outside of the unit regularly. To clean the inside, remove the outer cover and either wipe down the interior with a rag or use a can of compressed air. Reinstall the cover and see if the thermostat has power.
You’ll have to look further if the problem still isn’t resolved. There should be something on the display, even if the thermostat is off. If the screen is blank, then the device isn’t receiving power. In this case, you’ll want to check for the following:
You can determine if the wiring is defective by turning the fan from the “Auto” setting to the “On” setting. The blower should start, which means your thermostat is getting power. Or, if the AC is on, turn the temperature down; if the furnace is on, turn the temperature up. The level must be higher/lower than the current room temperature. If the thermostat is receiving power, your HVAC system should start up.
There are also more complex tests that involve checking the wire connections, disconnecting them, or using a multimeter. Unless you’re familiar with wiring in general, it’s best to consult a professional.
At NexGen, we can help select and install some of the most advanced thermostats on the market. Our team can troubleshoot and repair them as well. If your thermostat isn’t getting power, follow our suggestions above and contact us if you can’t get it working. We provide professional HVAC services throughout Southern California.
