How do you improve indoor air quality in Los Angeles?
You layer it. Wildfire smoke, dust and long allergy seasons each call for a different fix, so we recommend only the layers your home actually needs.
Air Scrubbers
Actively reduce airborne particles, wildfire smoke residue, and odors throughout the whole home.
UV Light Systems
Target biological growth at the coil and in the airstream — where it actually starts.
Measured Ventilation
Bring in filtered fresh air on purpose, instead of through leaks and cracked windows.
Smart Thermostats
Monitor humidity and runtime, and keep the whole system running right — from your phone.

Neighbors who found the standard.
Absolutely outstanding service – highly recommended! I needed a complete system replacement and had received multiple quotes from other companies — but Precise Air stood out for being the most honest and reasonably priced. Greg came over, carefully assessed our needs, and recommended the best system — not the most expensive one. The technicians were punctual, respectful, and meticulous. I'm so glad I found them.
Tony came out as scheduled and called me prior to arrival, and when he arrived he pinpointed the issue immediately. Some companies may try to inflame a simple common issue and exaggerate the service necessary to raise the price. Beyond that he was super neat, clean and courteous and clearly had expert knowledge of all things HVAC and more. I highly recommend.
Sean Poplar is outstanding. From his first visit he was able to diagnose the problem, specifically explain the malfunction and replacement items needed. His return visit was on time and on the mark resulting in a fully operational AC system. My thanks to Sean and Precise Air for their professionalism and top technological resources.
Francisco was very detailed and took a lot of care in his work. He ensured all systems were running efficiently before leaving my house, wiped down walls and any areas that were dirtied during installation, and took the time to explain to my grandmother how the new thermostat works in detail. I would definitely recommend the Precise Air Systems team.
Precise Air Systems Inc. is an excellent air conditioning company. We recently had our home 5 ton A/C replaced. They were super punctual on arrival, and worked at warp speed to get everything up and running in record time. Thank you to Jose Barajas and his team!
Had a preventative maintenance visit with Tony. The company's estimated arrival time was accurate and Tony's service was impeccable. I've had the pleasure of dealing with Tony, Jeffrey, and Joseph and they've all been 5 stars. Top tier service and experience all around!
I like Sean because he's diligent and answered all of my questions. I have had guys before that would make up problems — Sean is very trustworthy and I recommended him for my friends and family. Thanks Sean!
Tony from Precise Air was amazing. He was friendly, explained everything he was doing, he was extremely thorough, and continued troubleshooting until he got to the bottom of the issue that our AC unit was having. Truly wonderful service!
The experience was awesome. So helpful. Our house is so cool. Couldn't be happier. But specifically, Tony, is awesome. A stranger in the home putting in an air conditioner was expected to feel awkward. Not with him. Such a nice guy. And works so hard. Need a few Tony's in every business and I'd never have a complaint.
