AirQuest is made by the largest manufacturer of HVAC equipment in North America. Over 100 years old, the company is credited with inventing air conditioning and is a household name. We like AirQuest because we see higher quality for the same price other brands charge for lesser products. For example, every condenser has Copeland scroll compressor - the best US-made unit available. They use thicker gauge materials and more cabinet insulation for a more solid, quieter appliance. AirQuest heat exchangers use aluminized steel and have 20 year or lifetime warranties. The engineering, performance, quality and warranty surpasses the competition, all at a lower price with free shipping direct to you.
