HVAC Services

Your air conditioning system is made up of many interconnected parts. Problems can occur due to wear and tear, which is why routine maintenance is so important. We can recharge refrigerant, clean filters and coils, and inspect your system. Servicing traditional units, ductless units, electric units, or rooftop units is within the scope of our technicians’ capabilities. Replacing an old A/C is sometimes necessary to install the right-sized system, replace a failed unit, or improve home energy efficiency.

In addition to HVAC units, we specialize in oil, gas, and electric furnaces and various types of heat pumps. Costa Mesa residential and commercial customers may use absorption, ductless, air source, or geothermal systems, but we can repair or maintain your heat pump no matter what type you have.

But it’s not only the heating or cooling element that is the source of a problem. Inefficiencies can occur due to faulty thermostats, which we can fix or replace. We can sometimes make adjustments so your system will work more efficiently. Other areas we can address include air duct leaks, blockages, and contamination, which can not only affect system performance, but air quality as well. Fortunately, we can correct any of these problems. And when new insulation is needed in your walls or attic, Nexgen can handle that too.

Plumbing Services

A wide range of plumbing issues can affect your home or business. Even the most minor of them can lead to serious problems such as flooding and mold. Slow drains may require simple drain cleaning, but low water pressure and backups can mean you might need sewer cleaning. We can inspect your plumbing system with video cameras to spot hidden problems and provide non-invasive repiping where possible. Our piping experts can install reliable, long-lasting equipment, so you can depend on us for professional sewer repair. If tree root removal is required, we can break up roots and clear and repair your sewer pipe.

Costa Mesa customers rely on us even if there is a gas plumbing issue. A gas line rupture is a serious matter. If you smell sulfur, a gas leak is possible; leave your home and call Nexgen. It can be harmful to your health and cause an explosion. Fortunately, we can quickly correct the problem so there’s no longer any danger to you or your family.

In addition, we provide water heater service and can install tankless water heaters. If you need a water filtration system put in or serviced, Nexgen can be there, while our technicians service appliances including dishwashers and garbage disposals.
