HVAC Services

We provide an array of services to Buena Park homeowners. Our technicians can work with all types of HVAC units. Electric units have specific service requirements while traditional units under our care can last longer as well. We’re also experienced with everything from simpler ductless units to large, heavy rooftop units with special access and service requirements. Whether you need someone to check your A/C, furnace, or heat pumps, NexGen technicians are familiar with a wide range of mechanical systems and components and can often avoid system failure or more catastrophic damage.

Such systems provide heating and cooling so regular service can help maintain the comfort of your home during any season. We help maintain and repair oil, gas, and electric furnaces so issues can be addressed promptly, and inconvenient breakdowns can be avoided. Air duct cleaning helps improve indoor air quality and improve efficiency. We employ the proper equipment to avoid the risks of DIY cleaning. If you’re insulation needs to be improved, we can go into your ductwork, walls, or attic to help fix water or mold damage or help maintain comfortable temperature, humidity, and noise levels. Programmable and Wi-Fi thermostats can be installed to support your smart home needs as well.

Plumbing Services

Issues with piping can affect your entire home. To quickly address plumbing problems, we employ advanced leak detection equipment and techniques, including sewer and drain camera inspection. Mineral deposits, debris, and blockages can be removed manually or with hydro jetting and, when there is a hole or rupture in a pipe, we can complete non-intrusive repiping and tree root removal. Not every plumbing problem requires extensive repairs. We can help with drain cleaning if your kitchen or bathroom drains are slow or backing up. If there are more serious underlying issues, we can help with sewer cleaning and even perform sewer repair. Our Buena Park technicians can also quickly resolve a gas leak and repair your gas plumbing to restore your safety and peace of mind. Call us to find the cause of slow or running toilets, backed up sinks, or water sounds from your walls. Water heaters and garbage disposals connected to your plumbing system are complex and require expert service from time to time. We can address problems with water heater connections or sediment in the tank, and even install tankless water heaters. A clogged or malfunctioning garbage disposal can be serviced as well. Our technicians are so versatile they can perform electric panel upgrades to update your electrical system, improve your safety, and bring your home up to code.

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.

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.
