Service & Annual Tune-up

Denver Furnace Maintenance

Furnaces are mechanical equipment that need regular service, just like your car. Scheduling a tune-up at the recommended intervals keeps your heating system running efficiently and safely. Routine inspections also catch potential issues - cracked heat exchangers, failing ignitors, worn blower motors - before they turn into major problems during a cold snap.

What Does Furnace Maintenance Include?

A proper furnace tune-up covers the critical components that wear out or degrade over time. The inspection includes: burner assembly and ignition system cleaning, heat exchanger inspection for cracks or corrosion, flame sensor cleaning and testing, blower motor and wheel inspection, gas pressure verification, electrical connection tightening, safety control testing (limit switch, pressure switch, rollout switch), thermostat calibration, and air filter check or replacement. A dirty filter is the single most common cause of furnace problems - it restricts airflow, causes overheating, and forces the system to cycle on and off. If the inspection turns up a problem that needs attention, we can handle the repair during the same visit for most common issues.

Why a Heat Pump is the Right Choice for Your Home

Prevent Breakdowns

Regular maintenance helps identify potential issues before they turn into major problems, preventing expensive repairs and unexpected furnace failures during the cold Colorado winters.

Lower Energy Bills

A well-maintained furnace runs more efficiently, using less energy to heat your home. This translates directly to lower monthly gas bills and reduced operating costs.

Extend Equipment Life

Just like regular oil changes for your car, routine furnace maintenance can significantly extend the lifespan of your heating system, protecting your investment.

Safety First

Our maintenance includes thorough safety checks of critical components like the heat exchanger, flame sensor, pilot light, and gas connections. We test for carbon monoxide leaks and inspect for gas leaks to ensure your family's safety.

Had an estimate from a company that Costco uses. I was quickly convinced to switch to another product because that one had class action lawsuits. Received a $28k and was pressured to sign. Found UniColorado from an AI search and they not only saved me 5k on the total but, I have a much better furnace!! Great service, installation, follow-up and communication. Would recommend!! ⭐⭐⭐⭐⭐

UniColorado has great customer service. They installed an ac and furnace for me. They additionally have come out and answered any questions I have. Their whole operation is great.

The entire team with UniColorado worked tirelessly to get our new AC/Furnace installed. Understanding that we were working with a tight time frame, the guys got the job on the schedule quickly, and then went above and beyond to make sure everything was right after a couple of things didn't go according to plan. Could not recommend UniColorado more.

Is Furnace Maintenance Necessary?

We find the sweet spot for furnace service to be around 24 months for most Denver homes, though this varies by property. Homes with pets, heavy dust, or occupants with allergies benefit from annual service. The most important thing you can do between professional visits is stay on top of filter changes - every 30-60 days depending on your home. A clogged filter forces the system to overwork, accelerating wear on the blower motor and heat exchanger. If your furnace is 15+ years old and you're seeing rising gas bills or inconsistent heating, a tune-up is a good time to evaluate whether a new furnace or heat pump conversion makes financial sense.
