We carry the top brands of HVAC equipment including: American Standard, Amana, Daikin, Rheem, Carrier Commercial and Lennox.

From minor equipment repairs and system maintenance to new equipment installation, the professionals at A & S HVAC will exceed your expectations for quality service at affordable prices.

Routine maintenance is the most important and valuable service we provide. Proper maintenance is the key to low utility bills and long equipment life. Preventive maintenance gives you more longevity to the existing equipment, and saves you unnecessary neglectful repairs.
