Heating Installation/Replacement

NexGen installs and replaces gas, oil, and electric furnaces as well as air source, ductless, geothermal, and absorption heat pumps. Our technicians can install and service packaged heating units as well. Every unit is installed correctly to ensure it will operate reliably and efficiently without any safety issues. If you have an older system, we can visit your home for a free evaluation and replace an old heater with a properly sized and configured unit. Our newer units meet the latest efficiency standards. We install high-efficiency, multi-speed gas furnaces and quiet, efficient heat pumps that provide comfort all year long.

Heating Repair

You never know when your heating system will develop a problem. Even a regularly maintained furnace can break down. Some issues include a cracked heat exchanger, dirty filter, damaged or slipped blower belt, electric ignition or pilot control problems, or other mechanical issues. Call us if you notice a unit frequently cycling, the pilot light flickers or turns yellow, or you hear unusual noises, which can indicate a clogged blower or worn ball bearing. Our team can also determine whether an issue is arising from a faulty or improperly set thermostat. Any issue can be quickly troubleshooted and resolved by our experienced technicians.

Heating Maintenance/Tune-Up

Today’s heaters have many maintenance points. Finding problems with fan blades, flame sensors, igniters, capacitors, gaskets, and pressure switches lets us address them early and avoid more costly breakdowns. We can even inspect air ducts to check for obstructions, leaks, and other issues that can affect comfort and air quality. Schedule a regular tune-up to test your furnace and check for leaks, fuel pressure issues, or signs of wear and tear. Tuning up the system allows it to run reliably at peak efficiency. Also, by lubricating motor and other moving parts, we can avoid excess wear and premature damage caused by repeated friction.

Benefits Of Having A Heating System

  • Increased comfort: A proper heating system makes your home warmer and more comfortable when it’s cold out.
  • Enhanced air quality: A reliable heating system helps remove dust and other debris in the air, which improves the indoor air quality in your home.
  • Energy-efficient: An energy-efficient heating system lowers your home’s energy use and reduces your heating bills while keeping your home warm.

Types Of Heating Systems


  • A furnace is a heating system that uses gas, oil or electricity to provide homes with heated air.
  • Furnaces have a blower that gathers air, which is then heated through the use of natural gas, oil or electrical heating elements and distributed throughout the home.
  • Types of Furnaces
    • Gas Furnace
      • A gas furnace heats air by using natural gas.
      • Gas furnaces have a lower fuel cost and last for many years, but they can be more costly to install and noisier to run.
    • Oil Furnace
      • Oil furnaces use heating oil to warm up air through a heat exchanger.
      • Oil furnaces have lower installation costs, but they require a steady supply of heating oil, which can fluctuate in price. They also need more frequent cleaning.
    • Electric Furnace
      • An electric furnace uses electrical heating elements to produce heated air through a heat exchanger.
      • Electric furnaces cost less to install and do not require as much maintenance, but they can be more expensive to run and tend to heat homes less efficiently.
  • Benefits of a Furnace System
    • A furnace system costs less in terms of fuel and uses less energy than other heating systems in colder temperatures.

Heat Pump

  • Heat pumps extract heat from outdoor air and move it inside a residential building.
  • Types of Heat Pumps
    • Air Source Heat Pump: This heat pump pulls hot air from outside into homes.
    • Ductless: Ductless, mini-split heat pumps are suitable for homes without ductwork or for heating certain zones or areas within a home.
    • Geothermal: This heat pump pulls heat from the ground into homes.
    • Absorption: These heat pumps use natural gas or other non-electrical sources.
  • Benefits of a Heat Pump
    • Heat pumps provide an energy-efficient way to heat homes, resulting in lower energy bills. Some can also act as air conditioners and keep homes cool in summer.

Package Units

  • Package units include all necessary components and parts that are typically housed in a single casing. These heating units offer a convenient way to keep smaller homes and other small spaces heated.

Components of a Heating System

There are two major choices when it comes to your heating infrastructure – the heat pump or the furnace. Here are some of the advantages for each option.

Air Ducts

These ducts direct heated or cooled air to vents throughout your home.

Flame Sensors

These are safety features on gas furnaces that indicate whether or not a flame is present to ignite the gas.

Fan Blades

These blades are part of the fan inside your heating system. The fan circulates air throughout your home.


The start and run capacitors in your heating system’s fan motor supply it with electricity.


The ignitor is a pilot light or electric component that heats up the gas in your furnace in order to produce heated air.


High temp gaskets seal the draft inducer blower and heat exchanger in heating systems.

Pressure Switches

These switches close up so that electricity can get through in order to ignite the furnace.


  • Digital Thermostats: These thermostats feature a digital display that allows you to adjust the temperature more accurately than manual thermostats.
    • Honeywell Thermostats: Honeywell offers programmable and non-programmable digital thermostats.
  • WiFi Thermostats: These thermostats allow you to adjust the settings from any location with Internet access.
    • Honeywell Thermostats: These WiFi thermostats, such as the Honeywell Pro 9000, are programmable and offer convenience and improved energy efficiency.
    • Nest Thermostat: The Google Nest thermostat is a “smart” thermostat that learns your typical schedule and makes temperature adjustments accordingly.

Amazing Reviews From Our Loved Clients

Not only did his team deliver promptly and on time, they were friendly and left with a professional install of my new A/C unit. I can’t mention the AWESOME price I got, but needless to say they can beat any deal, and will give you the fastest 1st-rate service available.
Wayne B.
Yesterday I had NexGen install a new furnace and a/c system to replace my 30-year-old system. Their representative Jeff met with me the day before to go over the system that would work best for my home, and presented me with a price I couldn’t turn down. Incidentally, NexGen’s price was over $3,000 cheaper than all other competitors.
Jack W.
My call was promptly returned by Jeff and an appointment was scheduled for the next day. Jeff presented an offer that I couldn’t refuse! A crew was available that day and came, saw and conquered. I had A/C that evening at a very fair price. Highly recommend NexGen.
