Heat Pump Repair and Service

Heat pump repair and heat pump service are two different jobs, and this page covers both. Repair is the emergency call when the system stops doing its job. Service is the scheduled visit that keeps it from getting there. Your heat pump is the only appliance in the house that works every month of the year, which means it earns real attention in both directions. Air Comfort Solutions LLC runs repair 24 hours a day and schedules service year-round — family owned, 35+ years in the trade, TDLR-licensed and EPA-certified, with a 5.0-star Google rating across 137 reviews.

What is the difference between repair and service?

Repair is reactive: something failed and we find and fix it, flat-rate, quoted before any work begins. Service is proactive: measured performance testing, cleaning, and honest condition reporting before anything breaks. On a heat pump the distinction matters more than on most equipment, because the machine never gets a season off. Small neglect compounds roughly twice as fast as it does on an air conditioner paired with a furnace, since there is no idle half of the year for wear to pause.

When should you call for heat pump repair?

Call when the system stops holding the setting in either mode, when the outdoor unit runs but the house will not warm or cool, when you hear grinding, buzzing or a loud clunk at changeover, when ice builds on the outdoor coil and stays there through a defrost cycle, when the backup heat strips run constantly in mild weather, or when a breaker keeps tripping. Heat pumps also fail in a way that fools people: the system cools beautifully all summer and then cannot heat in December, because the reversing valve or defrost control failed months earlier and nobody noticed.

What fails on heat pumps here?

Capacitors and contactors cooked by triple-digit afternoons, the same as any outdoor unit. Beyond that the list gets specific: reversing valves that stick or leak internally, defrost boards and sensors that misread and either skip defrost or run it constantly, slow refrigerant leaks that quietly rob capacity in both modes, outdoor fan motors, and condensate paths choked by our humidity. Because a heat pump runs year-round, a fault that would be seasonal on other equipment shows up as a bill that climbs every month instead of a dramatic breakdown.

What does heat pump service include?

Both modes get checked, because a heat pump can cool perfectly and still fail at heating. We clean the outdoor and indoor coils our humid air fouls, verify refrigerant charge by instrument rather than by guess, test the defrost cycle and its sensors, exercise the reversing valve, check capacitors, contactors and motor amp draws under load, measure airflow and static pressure, flush the condensate path, and confirm the thermostat and any backup heat staging behave correctly. You get a plain-language report: what is healthy, what is wearing, and flat-rate pricing on anything worth doing — your decision, before any work.

Why does backup heat staging matter?

Because it is where money quietly leaks. Electric resistance heat strips cost far more to run than the heat pump itself, and a thermostat wired or configured wrongly will call them in weather the heat pump could have handled alone. We see this often in homes where a thermostat was swapped by someone unfamiliar with heat-pump staging. Checking it takes minutes and can change a winter electric bill noticeably, which is exactly the sort of thing a scheduled visit is for.

What can you do yourself between visits?

A few things genuinely help, and none of them require tools. Change or check the filter on schedule — restricted airflow is behind a surprising share of the calls we run, in both seasons. Keep two feet of clearance around the outdoor unit and clear away leaves, grass clippings and mulch that pile against the coil. Do not stack anything on top of it. In winter, a light frost that clears on its own is normal; ice that builds and stays is worth a call rather than a wait. And if the backup heat seems to run in mild weather, note when it happens and tell us — that detail shortens the diagnosis.

What happens to an unserviced heat pump?

It fails in installments. Fouled coils tax the compressor a little more each month. A marginal defrost sensor waits for the first real cold snap. A slow refrigerant leak steals efficiency long before it stops the system. None of it announces itself until the day it does, usually at the least convenient moment, and by then the cheap fix has often become an expensive one.

What happens when we arrive?

Diagnosis before quoting, on a repair call and a service visit alike. The technician finds the actual fault rather than swapping the part that usually fails, shows you what he found, and explains it in plain language. Then you get a flat-rate price you approve before any work begins. We service every brand of HVAC equipment, including systems another company installed; Daikin and Trane are the lines we currently sell.

Is it worth repairing, or is it time to replace?

We will give you both numbers. A heat pump under ten years old with a failed capacitor, contactor or defrost sensor is worth fixing without hesitation. Past ten to twelve years and facing a four-figure repair — a failed compressor, a leaking coil, a bad reversing valve — replacement usually wins the math, especially as R-410A parts get scarcer and pricier. If it comes to that, our installation and replacement page explains how we size and verify the new system so it does not inherit the old one's problems.

Service, maintenance, or the plan?

One-off service visits suit a system that is acting slightly off or simply due for a checkup. Scheduled twice-yearly care is heat pump maintenance and tune-ups, and the $159/yr maintenance plan is the easiest way to buy it: two seasonal visits, a waived service-call fee, 10% off repairs, 5% off future equipment, and priority scheduling in the busy weeks.

What does it cost, and who shows up?

Flat-rate pricing per job, never by the hour, approved by you before work begins. First responders, veterans and seniors save 10% on all service and repair work through our local heroes offers, and larger work can be financed through Foundation Finance for qualified buyers. Every technician who reaches your door is TDLR-licensed, EPA-certified, background-checked and drug-tested.
