When you need heating services in Denver, you need a team that understands how thinner air changes the way gas burns. A heating solution that works for new builds on the southern edge of the metro may not work for Denver Squares in older neighborhoods. At Horizon Services, we understand the unique needs of Colorado homeowners. We’ve been servicing furnaces, boilers, and heat pumps across Denver since 1998.

Complete Heating Services for Colorado Homes

We’re a full-service heating company, and we can help with all your heating needs, including:

Heating repair on all makes and models with same-day service.
Heating replacement and installation services, correctly sized for altitude.
Heating maintenance and annual tune-ups.
Thermostat repair, ductwork, and airflow corrections.
24/7 emergency response for when the heat goes out overnight.

Heating Repair

Our technicians repair all makes and models of furnaces, boilers, and heat pumps across the Denver area, from failed igniters and blower motors to faulty thermostats and more. We’re frequently called out to repair units that are running but not producing any heat, usually because the burners aren’t lighting. Whatever we find, we’ll explain it and give you a price to approve before we start.

Our commitment to quality service is reflected in the warranties we offer. All repairs performed by our certified technicians come with a one-year parts and labor warranty. For clients enrolled in our Peak Advantage Service Agreement, we extend this coverage to two years for even greater peace of mind.

Heating Maintenance & Tune-Ups

We recommend annual heating maintenance to prevent unnecessary breakdowns when your system is put under pressure.

Our technicians will clean your unit’s burners and flame sensors, test safety controls, check gas pressure and combustion, inspect the heat exchanger, tighten electrical connections, and measure airflow. Without regular maintenance, any one of these components can fail, leaving you without heat during the depths of winter.

Our Peak Advantage Service Agreement includes an annual visit and much more. Members get:

Same-day service at regular rates seven days a week.
A repair warranty extended from one year to two.
A complimentary visual check of the water heater, humidifier, and air cleaner.
Carbon monoxide detector tests.
Confirmation that your gas-fired equipment is running safely.

Heating Installation & Replacement

Whether you need a replacement because your heater wasn’t properly sized or you need a brand-new unit because your old one failed, we can help.

Manufacturers rate their equipment at sea level, so a heating unit in Denver, which is at 5,280 feet above sea level, burns less fuel and puts out less heat than an identical system on the coast. We’ll calculate how much heat your home needs, size the unit for our altitude, expertly install it, and confirm it’s running properly before we leave.

Furnace Services

At Horizon Services, we handle repairs on all makes of electric, gas, and propane furnaces. We also fix airflow problems in Denver’s older neighborhoods where original ductwork hasn’t been updated for extensions or finished basements.

With regular maintenance and good airflow, your gas furnace should last between 15 and 20 years. Without it, the heat exchanger that separates the burning gas from the air blowing into your rooms is usually the first component to fail, and once it cracks, carbon monoxide can get into your home. At that point, the unit has to be replaced rather than repaired, and we can help with your new furnace installation.

Boiler Services

Our boiler services cover boiler repair and hot water heating systems plus full boiler installation. Plenty of bungalows and other pre-war homes across the city still have boilers, and a well-maintained boiler will heat your home just as efficiently as forced air without the hassle and cost of conversion.

Heat Pump Heating Services

Unlike a furnace, which burns gas to heat the air, a heat pump moves heat that’s already there. Even freezing air holds usable heat that can be extracted and brought indoors, using far less energy than systems that generate heat.

Our heat pump services cover your whole system, from sizing and installation to repair to the annual maintenance that keeps your pump working efficiently.

Common Signs Your Heating System Needs Service

If you notice any of the following, contact us to book a service:

Cold or lukewarm air when the system is running
Short cycling, when the unit switches on and off repeatedly
Gas bills climbing without a rate increase or a change in habits
Rooms that don’t warm up
New banging, squealing, or grinding noises
A yellow or flickering burner flame when it should be a steady blue

If your carbon monoxide alarm starts to repeat a pattern of loud beeps, it usually means carbon monoxide is present. Get everyone outside, then call 911. We recommend testing your alarms regularly and familiarizing yourself with their pattern so you can distinguish a leak from a low battery.

Repair vs. Replace: What’s Right for Your Heating System?

When deciding between repair and replacement, consider repair costs, the system’s efficiency and performance, its age, repair frequency, and its maintenance history.

Repair is the best option if your system has been well maintained, is within its expected life, and the repair cost is significantly less than the cost of a new unit. Consider replacement when the heat exchanger has cracked, repair bills are mounting, efficiency has dropped enough to show up on your bill, or the unit wasn’t sized properly in the first place.

We’ll be clear about what we find, and advise you on your options.
