Installed a UV light in our HVAC system and a better filter. Noticed less dust and allergies have improved. Knowledgeable HVAC tech who cared about air quality. (Denver)

Added a zoning system so upstairs and downstairs have separate temperature controls. Game changer for comfort. Excellent HVAC upgrade for our home. (Denver)

Replacing an attic AC unit is not easy but their crew handled it like pros. New unit fits perfectly and the attic is sealed back up tight. Professional HVAC work. (Denver)

Had all our ducts cleaned. Huge difference in air quality and the system seems to run more efficiently. Worth doing every few years. Good HVAC maintenance. (Denver)

Furnace stopped working on a cold night. They came out first thing in the morning, found a bad igniter, and had us warm again by noon. Fair pricing for HVAC repair nearby. (Denver)

Major Heating fixed our furnace ignitor on a 15-degree night. $275 for the repair. Tech was professional, showed me what failed, and recommended a maintenance plan. Denver winters are brutal and I can't be without heat. They earned a regular customer.
