About Controlling Systems Heating, AC, and Electrical Repair

Controlling Systems Heating, AC, and Electrical Repair has operated from North Broadway since 1976, giving it roughly fifty years in the north Denver market, longer than most shops on this list. The company's technicians carry NATE certification, and the business backs its work with a stated 100 percent satisfaction guarantee.

The heating and cooling lineup covers furnaces, boilers, heat pumps, and general air conditioning, plus ductless mini-splits, indoor air quality work on ducts and humidifiers, and membership maintenance plans. The company also helps customers navigate rebates and tax credits tied to efficiency upgrades, a detail that matters in Colorado given the state's active heat pump incentive programs. Beyond HVAC, Controlling Systems runs an electrical division and installs solar systems, which is a broader spread than most furnace-and-AC shops attempt.

One reviewer, Ben P, described the company responding same-day when their HVAC system failed after a trip, and another, Patricia, singled out technician Chris for a thorough mini-split sizing and installation that accounted for each room individually rather than a one-size estimate. The office answers 24/7 for emergencies, can be reached by email at info@controllingsystemsco.com, and offers financing on larger jobs.

The company lists a license number, LIC235711, though the issuing authority is not specified on the site, and no BBB rating or manufacturer dealer certification beyond NATE is published.

Controlling Systems suits homeowners who want a shop with real neighborhood tenure and technicians willing to size a mini-split room by room rather than guess. It suits less well someone who wants to verify a license number against a public database quickly, since the issuing authority is not stated. Ask the office which agency issued LIC235711 and get a room-by-room load calculation in writing before a mini-split installation.
