Attic Fan

Attic Fan has operated as a whole house attic fan specialist in Denver since 1976, making it one of the longest-running ventilation contractors in Colorado. The company holds an EPA Lead-Safe certification and has maintained BBB membership since 1977, accumulating over 10,000 successful installations. With 31 customer reviews yielding a 4.6-star average rating, Attic Fan serves Denver-area homeowners seeking energy-efficient cooling alternatives. The business maintains standard hours from 8 AM to 7 PM seven days a week, accommodating residential clients throughout the metropolitan area who want to avoid the high operating costs of traditional air conditioning.

What distinguishes Attic Fan is its narrow specialization in whole house ventilation rather than the broad range of services typical of full-service HVAC companies. The company promotes its systems as capable of cooling an entire home for approximately 25 cents per day, with operating costs between one and five cents per hour compared to seventeen to sixty-seven cents for conventional AC. The website claims most customers reduce cooling bills by fifty to ninety percent, and the systems draw fresh outdoor air every few minutes rather than recirculating stale interior air. For Denver specifically, the company emphasizes that the region's cool evening temperatures make whole house fans particularly effective, often eliminating the need for air conditioning entirely. The business also markets that adding a whole house fan can extend the lifespan of existing AC systems by reducing their runtime.

Customer feedback highlights technician Enrique across multiple positive reviews, with homeowners praising his punctuality, thorough explanations, and attention to cleanup. One reviewer noted Enrique removed an old swamp cooler and expertly patched the roof himself, while another mentioned he provided additional attic insulation guidance during installation. Jeff Ruys described the company as willing to help customers perform their own minor repairs by explaining exact parts needed rather than automatically charging for service calls, characterizing them as a stand-up company focused on creating satisfied customers rather than maximizing billable visits.
