7 Signs It’s Time to Replace Your Furnace in Northglenn, CO
Furnaces don’t last forever. If you’re a homeowner in Northglenn, CO and your system is showing signs of age, now’s the time to act—before winter arrives. Here are 7 signs your furnace may be ready for replacement, and what to do next.
1. It’s Over 15 Years Old
The average lifespan of a furnace is 15–20 years. If yours is near or beyond that, efficiency and reliability can decline fast. Consider a modern replacement for better comfort and savings.
2. Rising Heating Bills
If your energy usage hasn’t changed but your bills are climbing, your system may be working harder than it should. Energy audits can confirm inefficiencies.
3. Uneven Heating or Cold Spots
Struggling to heat certain rooms? That’s often a sign your furnace or ductwork can’t keep up—especially in older homes.
4. Strange Noises
Banging, popping, or rattling sounds? These may signal internal damage, cracks, or worn-out components that make repair less cost-effective.
5. Frequent Repairs
Needing repairs every season? If repair costs are stacking up, it’s likely more economical to upgrade your system.
6. Poor Air Quality
An aging furnace can circulate dust, allergens, or even carbon monoxide. Consider adding an air purifier with your new system for better IAQ.
7. Burner Flame Is Yellow, Not Blue
This could indicate incomplete combustion or a gas leak—both serious safety risks. Shut down your system and call us immediately.
