HVAC Services

At NexGen, we are experienced at servicing all types of HVAC systems. Our team can service traditional units, electric units, ductless units, and rooftop units as well as thermostats. When a system or component breaks down, we can be trusted to address the problem. Our emergency availability means we can dispatch a technician to your Pasadena home if you’re sitting down for dinner, getting ready for work, or are awakened by a sudden problem. We can fix any air conditioning issue or install the newest most reliable, energy efficient units on the market today. Licensed technicians can service air source, ductless, and absorption heat pumps and even geothermal units. These systems provide heating and cooling and you don’t want to be without them in Pasadena’s warm, temperate climate or even on a chilly winter night. We can also service an electric, oil, or gas furnace with emergency repairs or routine maintenance. Call us right away if the pilot light is out or the unit is making noise or not heating your home properly. You can also trust us to professionally clean an air duct to protect your home and equipment. If you want to further improve the efficiency of your home, we can install the latest programmable and Wi-Fi thermostats. Home insulation contributes to comfort and efficiency as well; we can check wall, floor, and attic insulation to ensure it is suitable—and improve it if necessary.

Plumbing Services

NexGen is Pasadena’s most trusted plumbing company. We can address any issue with water piping or even your gas plumbing. Our team is trained and equipped to safely and effectively deal with any type of plumbing emergency. Whether you have a running toilet, slow drain, or low water pressure, you can call us to send a technician who will thoroughly check the plumbing system. We are relied upon for drain cleaning and even more complex jobs such as sewer cleaning and even sewer repair. Advanced leak detection methods are employed to find issues at their source, and we can provide repiping if necessary, without tearing up your floors, yard, or driveway (thanks to the latest trenchless piping methods). If tree roots have encroached on or penetrated a pipe, we can use our tree root removal expertise and equipment to resolve the problem. And when you suspect a leak in your gas line, we can be there quickly to fix it, so you are no longer in danger. Natural gas is a major explosion hazard so if you smell sulfur or hear hissing from pipes, call our hotline right away. Additionally, outdated electrical equipment can put your home at risk of fires, explosions, and injuries related to burns and shocks. NexGen does electrical panel upgrades to increase voltage capacity to support your home appliances, devices, and equipment.

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.
