Air Quality & IAQ reviews
What Los Angeles homeowners say about our indoor air quality team
“After the Eaton Fire, our ducts smelled like smoke. LC did a full cleaning — negative air pressure, rotary brushes, the works. Air quality in our home is completely different now. They were sensitive to what our neighborhood went through.”
“Post-fire air quality in our Altadena home was terrible. LC installed a whole-house HEPA filtration system and UV germicidal light in the air handler. Our allergist confirmed improved air quality on our next visit.”
“LC installed a whole-house dehumidifier in our South Pasadena home. We had issues with condensation and mildew smell every summer. The unit has eliminated the problem and our air feels completely different inside.”
“Our AC stopped working during a heat wave and LC had a technician here within two hours. He diagnosed a bad capacitor, had the part on his truck, and fixed it on the spot. Fair price, no upsell. Will use again.”
