Denver Heating Repair During Extreme Cold in Colorado

The last several days of extreme cold across Denver, Aurora, and Littleton have put serious strain on home heating systems. When temperatures drop this low and stay there, furnaces and heat pumps are forced to work nonstop, which often exposes small issues that quickly turn into major breakdowns.

At Hartzell Heating & Air, we are already seeing an increase in calls for Denver heating repair, especially from homeowners whose systems were struggling before the cold snap hit.

If your home is having trouble staying warm, this guide explains what is happening, what to watch for, and when it is time to call a professional.

Why Extreme Cold Causes Heating Problems in Denver

Colorado weather is unpredictable, but prolonged cold is especially hard on heating systems. When your furnace or heat pump runs for extended periods, worn components, restricted airflow, or aging equipment are more likely to fail.

Common cold-weather heating problems include:

• Furnaces running constantly but not heating the home

• Heat pumps losing efficiency in freezing temperatures

• Frozen condensate or drain lines

• Dirty air filters restricting airflow

• Ignition or flame sensor issues

These problems often show up suddenly during cold snaps, even if the system seemed fine earlier in the season.

Signs You May Need Denver Heating Repair Right Away

When temperatures are this low, heating issues should not be ignored. Waiting too long can lead to complete system failure or even frozen pipes.

Watch for these warning signs:

• Cold or lukewarm air coming from vents

• Uneven temperatures from room to room

• Furnace short-cycling or turning on and off frequently

• Loud banging, rattling, or grinding noises

• Thermostat set correctly but the home stays cold

If you notice any of these symptoms, scheduling Denver heating repair early can prevent a much bigger and more expensive problem.

How to Protect Your Furnace During Extreme Cold

While some issues require professional service, there are a few steps homeowners can take to reduce strain on their heating systems during extreme cold.

Helpful cold-weather heating tips:

• Replace dirty furnace filters to improve airflow

• Keep vents and returns clear of furniture or rugs

• Check thermostat batteries and settings

• Keep the area around your furnace clear

• Seal drafts around doors and windows

These steps help your system operate more efficiently, but they will not fix mechanical failures. If your furnace is still struggling, professional service is needed.

Heat Pumps and Cold Weather in Colorado

Many Colorado homes now use heat pumps, which are designed to handle colder climates. However, extreme temperatures can still push them to their limits.

During cold snaps, homeowners may notice:

• Longer run times

• Backup heat engaging more frequently

• Ice buildup on outdoor units

If your heat pump cannot maintain a comfortable temperature or is icing excessively, it may need service or adjustments to handle Colorado’s winter conditions.

When to Call for Professional Denver Heating Repair

Some heating problems cannot wait, especially when outdoor temperatures remain dangerously low.

You should call a professional immediately if:

• Your furnace stops producing heat

• Your heat pump is not keeping up with demand

• Your home temperature is dropping quickly

• You smell gas or burning odors

Fast response during extreme cold can protect your family, your home, and your heating system.
