Quick Answer
Should I repair or replace my furnace or AC?
In Colorado Springs, replace a furnace older than about 15 years or an AC older than 10–15 years when it needs a major repair; repair younger systems with small, one-off problems. A common rule: if age times repair cost tops $5,000, replacing usually wins. Strong Heating And Cooling gives honest, free recommendations.

- Heat pump: 10–15 years

Altitude & Front Range context
Harsh sun, big temperature swings, and long heating seasons along the Front Range wear equipment. Systems that were never derated or sized for altitude often wear out sooner.

More questions
How long does a furnace or AC install take?
Most straightforward like-for-like furnace or AC replacements in Colorado Springs are completed in a single day. Jobs that need new venting, ductwork changes, or a full system swap can take longer; we give you the timeline with your upfront quote.
What size furnace do I need at 6,000+ feet?
It depends on your home's square footage, insulation, windows, and layout — not a rule of thumb. Gas furnaces lose output at Colorado Springs' altitude, so Strong Heating And Cooling runs a Manual J load calculation and sizes for derated output. See our high-altitude furnace sizing guide for the details.
