    Are You Interested in Improving Your Indoor Air Quality in Lomita, CA?

    The heat sealing from the insulation on your home is an important part of maintaining energy efficiency, both in winter and in summer. But as a side effect, your home will receive less fresh air circulation, which can result in air that is too stuffy, too dry, or filled with too many contaminating particles. For better indoor comfort and health for your household in Lomita, CA, call on AZ Air Conditioning and Heating and let our indoor air quality experts find solutions. We have many quality products and the skills to install them.

    We Offer Air Purifiers

    To get rid of the majority of unhealthy particles in your air, a professionally installed air purifier is an excellent solution. Rely on our IAQ specialists to find the right kind of electronic or UV air purifier to eliminate the contaminants that are circulating through your HVAC system and into your living spaces.

    We Offer Humidifiers

    If the air in your home is too dry—a common trouble in Southern California—you should consider calling us to install a whole–house humidifier. Small portable humidifiers can provide decent service for a single room, but it takes a full–sized unit integrated into the HVAC system to effectively provide your home with comfortable and healthy indoor humidity levels throughout.

    We Offer Dehumidifiers

    Should your home suffer from the opposite problem—air that is too humid—you will also need our assistance. A properly sized and installed whole–house dehumidifier will balance out the humidity level so you won’t need to continually run the AC to overcome the extra discomfort, and it will also reduce the growth of mold and the development of damaging wood rot.
