The Pikes Peak Deep-Freeze: Is Your Furnace Ready for Sub-Zero Temperatures?

When winter hits Colorado Springs, the weather can change in a flash. One minute it is sunny, and the next, an arctic blast drops temperatures below zero. When you live at over 6,000 feet, your heating system works much harder than it would at sea level.

If your furnace is not ready, a sudden deep-freeze can leave your home freezing cold and lead to an expensive emergency repair. Here is how you can check your furnace right now to make sure it handles the Pikes Peak winter.

Why High Altitude Puts Extra Stress on Your Furnace

Air is thinner at high altitudes like El Paso County. Because there is less oxygen in the air, your furnace has to burn more gas and push harder to generate the exact same amount of heat.

When outdoor temperatures plunge below zero, your furnace runs longer cycles. If parts are worn out or clogged with dust, that extra strain can cause the system to shut down right when you need it most.

A Simple 5-Point DIY Check Before the Big Freeze

You do not need to be an HVAC expert to protect your heating system. Run through this quick checklist before the worst of winter arrives:

1. Swap Your Air Filter: A dirty filter blocks airflow, forcing your furnace to work twice as hard in the thin mountain air. Change your filter every 1 to 3 months.
2. Clear Outdoor Vents: Heavy snow or drifting ice can block your high-efficiency furnace's intake and exhaust PVC pipes on the side of your house. Keep them clear to prevent dangerous carbon monoxide build-up.
3. Test Your Thermostat: Switch your system from cooling to heating on a mild day and test it. Make sure the heat kicks on right away and matches the temperature you set.
4. Listen for Strange Noises: Rattling, banging, or screeching sounds mean a part is loose or failing. Catching these noises early stops total breakdowns on freezing nights.
5. Schedule Professional Maintenance: A trained technician can inspect your heat exchanger, test gas pressure, and clean internal parts so your system runs safely all winter.

When to Call the Pros

Some maintenance tasks are best left to licensed professionals. If your furnace is blowing cold air, cycling on and off too fast, or refusing to turn on, do not wait for the indoor temperature to drop.
