Watch for six signs: unusual noises, weaker heating or cooling output, rooms that never even out, rising energy bills, a system that runs constantly or short cycles, and ice that will not clear from the outdoor unit in winter. Age past 10 to 15 years shifts the answer from repair toward replacement.

Signs That Point to Repair

  • New noises. Grinding or screeching means motor bearings. A hard buzz at startup with no fan movement usually means a failed capacitor — inexpensive if caught early.
  • Reduced output. Air that is cool but not cold, or warm but not hot, often points to low refrigerant charge or a fouled coil.
  • Uneven temperatures. Duct leakage, blocked returns, or a failing reversing valve.
  • Constant defrost cycling or ice that will not clear in winter — a defrost control or sensor problem.

Signs That Point to Replacement

A heat pump past 12 to 15 years facing a compressor or reversing valve failure is rarely worth repairing — those are the two most expensive components in the system. Two or more repairs in consecutive seasons means the same thing. And if the system runs R-22 refrigerant, a leak is effectively a replacement decision: the refrigerant is phased out, expensive, and the leak will recur.

Rising Bills Are the Earliest Warning

Compare your PNM bill against the same month two years ago. Efficiency loss shows up before mechanical failure does, and it is the cheapest moment to intervene.

Heat Pumps in New Mexico

They perform well here — our long, mild shoulder seasons are exactly where heat pumps are most efficient. But they run year-round rather than seasonally, which means roughly double the run hours of a cooling-only system and correspondingly faster wear. Annual service matters more, not less. In Santa Fe and the East Mountains, where deep cold is common, a hybrid fuel system that hands off to a gas furnace below a set temperature often outperforms a heat pump alone.

Getting a Straight Answer

We quote the repair and the replacement side by side with realistic remaining life, and no technician here works on commission. Twice-yearly service through the Care Club catches most failures early, and financing is available on replacements.
