Many homes in Security-Widefield were built with gas furnaces that are now 20 years old or older. Equipment at that age faces mounting repair costs, declining efficiency, and increasing reliability risk. A modern high-efficiency furnace at 96 percent AFUE delivers meaningfully lower monthly gas bills compared to equipment from the 1990s. If you’re not sure whether repair or replacement makes sense, visit our heating repair page for guidance, or our furnace services page for furnace-specific information.

Proper sizing is the most important factor in a successful heating replacement. An oversized furnace short-cycles, producing uneven temperatures and excess component wear. An undersized system runs continuously and struggles on the coldest Security-Widefield nights. WireNut performs a load calculation before recommending equipment so the system we install actually matches your home’s heating requirements.

• System age and repair history: Systems over 15 years old with multiple recent repairs are strong replacement candidates.
• Efficiency gains: A 96 percent AFUE furnace uses significantly less gas than an 80 percent unit from 20 years ago. The savings are real and calculable.
• Ductwork condition: Older duct systems in Security-Widefield homes often have significant air leakage. Addressing it during replacement maximizes new equipment performance.
• Furnace vs. heat pump: Both are viable in Security-Widefield’s climate. WireNut can model both options with real cost and savings estimates.

A few factors Security-Widefield homeowners should weigh before committing to a heating system replacement.

Furnace vs. Heat Pump: Which Is Right for Security-Widefield?

Gas furnaces remain the most common heating system in Security-Widefield because they provide reliable high-temperature output even on the coldest nights. A modern 96 percent AFUE furnace is significantly more efficient than older equipment. Heat pumps have become increasingly viable as cold-climate technology has improved. Modern units maintain meaningful efficiency down to 0 degrees Fahrenheit, which covers the vast majority of Security-Widefield winter conditions. WireNut can model both scenarios with realistic numbers based on current energy prices and your home’s heating load so you can choose based on facts, not assumptions.

Should I Replace Just the Furnace or the Whole System?

If your air conditioner is also aging, coordinating both replacements makes sense. Matching equipment from the same manufacturer at the same efficiency tier often qualifies for better warranty terms, and the labor overlap saves money compared to two separate projects. That said, if your AC is relatively new and performing well, replacing only the heating system is entirely reasonable. WireNut gives you an honest assessment of your AC’s condition during the heating estimate so the decision is yours to make with accurate information.
