Denver metro · furnaces & air conditioning

The house is cold at six and hot by three.

Highline repairs and replaces the furnaces and air conditioners that have to keep up. No-heat calls go out first.

No heat after dark is a phone call, not a form. (303) 555-0194

Heating

Furnace repair

No heat, a furnace that lights and quits, a heat exchanger that is no longer safe.

Sample prices, not an invoice.

Financing

A replacement should not wait on a tax refund.

A third-party lender can spread it out if you are approved. A sample $9,400 furnace at 9.99% for 60 months is about $200 a month. This site does not take an application.

How financing works

The measurement

Altitude first. Tonnage second.

Brick bungalows still have the ducts from a gravity conversion nobody resized. A charge is checked for a mile of altitude, not for the sticker on a sea-level brochure.

Replacement visits

Service area

The metro loop, not the whole Front Range.

Trucks would leave the Evans Avenue shop. Boulder, Castle Rock, Evergreen, and Brighton are outside it.

Not testimonials. Highline is fictional. A live site would use this layout for reviews the company can stand behind.

  • Sample

    “The heat exchanger on our 2004 furnace was cracked. They condemned it instead of selling us a control board, and the house had a new furnace in before the next front.”

    “The capacitor died on a 98° Saturday. They answered, they came, and they did not add refrigerant to a system that did not need it.”

    “They quoted the house, not a tonnage off a postcard. The ducts in our 1925 bungalow were the actual constraint.”

FAQ

Before you call.

All questions
What does a visit cost before anyone opens the cabinet?

The sample diagnostic fee is $89 during shop hours, Monday through Saturday, 7:00 to 7:00. It comes off the bill if you approve the repair on that visit. After-hours no-heat and no-cool carries a sample trip fee of $149. These are demo figures, not a quote.

How soon can someone come if there is no heat?

No-heat and no-cool go out before tune-ups. While the board is open, that usually means the same day. After 7:00 and on Sunday, the on-call tech takes those two calls and lets maintenance wait until morning.

Which neighborhoods do you actually run?

Denver and the inner suburbs: Aurora, Lakewood, Arvada, Westminster, Thornton, Wheat Ridge, Englewood, Littleton, Centennial, Golden, Highlands Ranch, and Parker. Boulder, Castle Rock, Evergreen, and Brighton are outside the loop. The service-area page will tell you from the ZIP before you book a truck we will not send.

What equipment do you work on?

Forced-air gas furnaces, central air conditioners, and air-source heat pumps. We do not take steam or hot-water boilers, swamp coolers, or window units.
