Indoor Air Quality and Filtration

NexGen has a strong reputation for providing top-notch indoor and improvement services in the Simi Valley. Indoor air pollution is a problem many face. Harmful pollutants can be several times more concentrated indoors than they are outside. To improve your indoor air quality and reduce respiratory and other health symptoms, we can provide:

  • Air Filtration Installation: Proper air filtration can mitigate any pollutants that manage to enter your home or HVAC system. We can install a duct-mounted air scrubber, UV filters with ionic air scrubbers, and a MERV 11 rated four-stage filtration system.
  • Air Duct Cleaning Services: A range of harmful pollutants may be lurking in your ductwork. Dust, animal dander, pollen, mold, insects, rodents, and more can contaminate ducts, circulate in your home, and cause blockages, which can strain your HVAC system. We can use HEPA vacuums, deodorizes, and other equipment to resolve cleanliness issues.
  • Air Duct Sealing Services : Duct leaks can introduce contaminants and lose a significant amount of conditioned air. NexGen uses advanced equipment and techniques to not only clean ducts, but seal holes, cracks, and loose connections to minimize air loss. We’ll even inspect the condition and design of ducts to see where additional improvements can be.

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.
