A local furnace repair pro can provide a quote for your specific needs. During the cold and snowy winters in Denver, Colorado, a broken furnace can be a homeowner’s worst nightmare. In many cases, a timely repair is more affordable than replacing the unit altogether.

Furnace Repair Cost Factors 

When your furnace breaks down in Denver, your repair bill is primarily determined by the specific part that needs to be replaced. Costs are also influenced by local labor rates, the type of furnace you have, and the complexity of the repair. Most homes in Denver have natural gas furnaces because of their powerful heating capabilities and the city’s natural gas infrastructure.

Repair Cost by Part

Regardless of their fuel source, furnaces are complex appliances that have a lot of working parts. Some of those parts significantly influence furnace repair costs, while others are simpler and less costly to repair.

Here is the average furnace repair cost based on the part:

Maintenance Cost

A furnace requires regular maintenance in order to operate efficiently. Otherwise, dust and other debris can clog burners, the pilot light, and other parts, causing more wear and tear on the system. Maintaining your furnace increases energy efficiency, extends the life of your unit, and gives you peace of mind—something that’s essential for homeowners navigating the harsh winters in Denver.

A furnace inspection costs $80 to $100 on average, and you need to schedule an inspection at least once per year to keep your system running smoothly. An advanced inspection, which includes cleaning and a tuneup, costs $125 to $200.

Additional maintenance costs include filters and air duct cleanings. You need to replace the filters once every 90 days, which will cost $4 to $140 per year. Schedule duct cleanings every three to five years, and expect to spend $275 to $500 for the cost of cleaning air ducts.

Cost per Hour

Furnace repairs cost $50 to $150 per hour for the labor, plus you’ll need to budget for the cost of parts. Small repairs may be billed at a $100 to $200 minimum rather than by the hour.

One of the quickest repairs is to replace a dirty filter, which only takes a few minutes and is easy to DIY. Some of the more difficult, time-consuming parts to repair include the blower motor, the draft inducer motor, coils, and the heat exchanger.

HVAC Pro Costs

Approximately 40% to 70% of your furnace repair cost will go toward labor, which might fall between $132 and $230 for smaller jobs in the Denver area. The cost of living is 10% to 20% higher than the national average in this Colorado city, so labor rates are steeper than in other parts of the county. Labor fees might also depend on the complexity of the repair, the type of furnace, and the technician’s experience. 

Permits

The cost of permits will be included in your final bill, and it’ll be around $75 to $400 (or possibly higher, depending on the scope of the work). 

In Denver, you’ll need a permit for major HVAC repairs, which includes replacing the heat exchanger, blower motor, and other large components. Minor repairs (such as swapping out the thermostat) might not require a permit. Your HVAC contractor will handle the logistics of the permit process.

Do Furnace Repairs Increase Home Value?

Furnace repairs don’t make your home more valuable. They’re not considered upgrades like landscaping redesigns or bathroom remodels. That said, maintaining your furnace ensures that your home’s value won’t decrease if it goes on the market.

A furnace is a non-negotiable for homeowners in the Denver area, who want a property that will get them through Colorado winters. A furnace that’s malfunctioning will be a major turn-off for buyers, and it’ll also create problems during the home inspection. What’s more, a broken furnace can cause safety hazards like gas leaks, so getting it fixed will protect your property in the long run.

You’ll see a greater return on investment (ROI) if you replace your furnace instead of repairing it. New HVAC systems have an ROI of 30%, but replacing a unit doesn’t always make sense, depending on your specific circumstances.
