How To Choose An AC Repair Company In Denver

Repair or replace?

If the unit is over 15 years old, uses R-22 refrigerant or needs a compressor, replacement is usually the better value. Ask for both prices.

Is a heat pump worth considering?

Many Denver homeowners replace a failed AC with a heat pump that also heats in winter. Xcel Energy and state rebates can offset much of the cost.

What is the diagnostic fee?

Ask whether it is credited toward the repair.

Do they offer maintenance plans?

A spring tune-up catches most problems before the first heat wave.

Conclusion

A broken air conditioner in a Denver heat wave is miserable. Save a number from this list now, schedule a spring tune-up and ask for repair and replacement prices side by side when something fails.
