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, they use only scroll compressors, thicker gauge materials and extra 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.
