The air inside your Atherton home directly impacts your family's health, comfort, and even sleep quality. DG Heating & Air Conditioning offers advanced indoor air quality (IAQ) solutions that go beyond temperature control to create a truly healthy living environment. We address the unseen contaminants circulating through your HVAC system.

Our IAQ services include professional air duct cleaning, which removes accumulated dust, allergens, and mold from your ductwork, improving system efficiency and air freshness. For homes with ductwork issues or for adding climate control to new spaces, we provide expert duct removal, replacement, and sealing. We also install cutting-edge air purification technologies like HEPA filtration systems, Air Scrubbers with ActivePure technology, and germicidal UV lights that neutralize bacteria, viruses, and volatile organic compounds (VOCs). For targeted comfort, our ductless mini-split installations offer efficient zoned heating and cooling without the need for extensive ductwork.

We approach indoor air quality with a holistic mindset. Our technicians will assess your home's specific needs—whether it's managing allergies, reducing dust, or controlling humidity with our dehumidifier services—and design a customized solution. By improving your home's air, we help you breathe easier, protect your HVAC investment, and enhance your overall quality of life in Atherton.
