When Should I Replace My Home's HVAC System?

A: Judge it by the invoice in front of you, not by the age on the data plate.

A capacitor at $150–$400 or a contactor at $150–$350 is routine, and worth doing on almost any system that's otherwise sound. The picture changes fast in the upper bands: a blower motor is $350–$900, an evaporator coil $1,000–$2,800, and a compressor $1,500–$3,500+. When repairs start stacking up in a single season on an ageing system, replacement usually becomes the cheaper decision.

Two Oklahoma-specific things to weigh:

• A refrigerant leak repair runs $250–$1,500, and repeat leaks on an old coil rarely stay fixed.
• Hail damage to condenser fins and line sets is common in this corridor and is often claimable on homeowner's insurance — check before you pay out of pocket.

Diagnostics are $95, waived if you approve the repair that same visit; replacement estimates are always free. Call 405-420-4895.
