Takes about a minute. No obligation.
A heat pump in this area has been running against real weather pressure for its entire service life, and that shapes what a contractor finds when they open it up. 736 severe weather events were recorded in Tarrant County, Texas between 2015 and 2024. At that rate, refrigerant lines, capacitors, and compressor windings carry a heavier cumulative load than the unit's age alone would suggest, which means a contractor cannot rule out weather-related wear before diagnosing a component failure. A system that looks old enough to fail on age might have reached that point sooner because of what this county's weather has asked of it.
Heat pump systems in housing this old are not on their first repair. Half the homes in Tarrant County, Texas were built in 1990 or earlier (2020-2024 ACS 5-year). A unit that has been serviced more than once accumulates a pattern: worn contactors, refrigerant that has been topped rather than traced, capacitors that are holding but marginal. When a contractor opens the system, what decides the scope is whether the specific parts it takes are still in supply. Older platforms narrow that list, and a contractor pricing the job prices the parts before they price the labor.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is usually where a repair investigation starts. It houses the compressor, which pressurizes the refrigerant, and the outdoor coil, which transfers heat with the air outside. When either of those fails, the whole system stops doing its job. A refrigerant leak, a failing compressor, or a damaged coil will each show up here.
Inside the house, the air handler holds the indoor coil and the blower fan. The indoor coil is where the heat exchange happens on the interior side, and the blower moves conditioned air through your home. A contractor also checks the reversing valve, which sits inside the outdoor unit and is what lets a heat pump heat and cool. That valve is a frequent repair target when the system runs but delivers the wrong kind of air.
The drawing shows a representative layout, and a licensed contractor determines which components apply to your specific system.

Severe Weather Events in Tarrant County
Extreme weather puts real stress on heat pump systems, which run harder and fail faster when conditions push outside normal ranges. How much of that pressure a unit absorbs is a local question, and the record below reflects what equipment in Tarrant County has been up against.
