HVAC Services

When it comes to air conditioning, you need a technician who is knowledgeable and trustworthy. Your home’s AC strongly impacts comfort and efficiency. NexGen can install and repair any type of system, provide maintenance that spots potential problems early and helps equipment last longer, and can replace your unit with something newer, more reliable, and energy efficient. You can trust us to service:

  • Traditional units
  • Electric units
  • Ductless units
  • Rooftop units

We are just as experienced with heating systems. Whether you need heat pumps repaired or replaced, an air duct cleaned, or someone to check the furnace or components in HVAC units, NexGen can be there to help. We can work with gas, oil, or electric furnaces. And if you have a geothermal, air source, ductless, or absorption heat pump, our Laguna Hills technicians are always trustworthy and courteous.

In addition, our technicians can install and service programmable and Wi-Fi thermostats and tune-up your heating and cooling system to optimize performance. If your insulation can be improved, we can help insulate your air ducts, walls, attic, or crawlspace to allow more comfortable temperatures, lower energy bills, and address insect, water leak, mold, and noise problems.

Plumbing Services

Minerals and contaminants in water, fluid pressure, and wear and tear affect every plumbing system. A minor leak can cause serious damage and escalate into something major quickly. NexGen employs advanced leak detection systems to spot problems at their source, so we can address any issues with your piping quickly. Whether the job requires tree root removal or fixing a gas line, we can use state-of-the-art, non-intrusive repiping techniques to restore your plumbing and eliminate any issues over the long run. A clogged drain can ruin your day. If plunging or snaking a toilet or sink drain doesn’t work, call NexGen and our drain cleaning technicians can get to work. They specialize in low tech and advanced methods such as hydro jetting to remove blockages. We also provide sewer cleaning services to alleviate backed up drains and foul odors. Sewer repair is possible using trenchless methods that don’t involve tearing up your property. If we can’t immediately spot the problem, we can use camera inspection to quickly get visual confirmation of the exact location and nature of the issue. We can address any problem with gas plumbing, garbage disposals, and water heaters. Our technicians can even help with electrical panel upgrades if you have an outdated panel. This eliminates many hazards.

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.
