The heat pump symptoms we hear most
- The heat pump runs all day and the house never warms up Low refrigerant charge, reversing valve stuck in cooling, or a failed outdoor fan
- The outdoor unit is buried in ice Defrost control failure, bad defrost sensor, or restricted airflow across the outdoor coil
- Air from the vents feels cool even on heat Compressor not staging, backup heat only, or a reversing valve solenoid problem
- It keeps switching to the furnace even in mild weather Dual-fuel changeover control, outdoor sensor drift, or thermostat wiring and setup
- Loud clunk or a screech when it changes modes Reversing valve, compressor mounts, or a failing fan motor bearing
Search for it as heat pump repair or heat pump service and you land in the same place: one visit, one written quote.
Safe things to check first
Worth a look before you call — sometimes it saves you the visit.
- 1Check the thermostat batteries and confirm it is set to heat with the fan on auto, not on emergency heat.
- 2Look for a tripped breaker at the panel for the indoor air handler and the outdoor unit, and reset it once.
- 3Change or check the filter. A loaded filter starves the indoor coil and can freeze up the system.
- 4Clear leaves, snow drifts, tall grass and stacked items away from the outdoor unit and make sure supply and return vents are open.

Why does my heat pump ice up in winter?
Some frost on the outdoor coil is normal, and the unit runs a defrost cycle to melt it. Solid ice means the defrost cycle is not completing, often a failed board, sensor or fan. That needs a technician before the coil is damaged.
Is emergency heat bad for my system?
Emergency heat is a backup, not a setting to live on. It bypasses the heat pump and runs electric strips or the furnace, so it costs more and hides the real fault. Use it to stay warm, then call us.
Can a heat pump be repaired or does it need replacing?
Most heat pumps we see are worth repairing. Capacitors, contactors, defrost boards, sensors and fan motors are common parts. Compressor or coil failure on an older system is where we lay out repair against replacement and let you decide.
What is a dual-fuel system and what usually fails?
Dual-fuel pairs a heat pump with a gas furnace and switches between them by outdoor temperature. Failures are usually in the changeover control, the outdoor sensor, or thermostat wiring and configuration, so the two never hand off cleanly.
My heat pump cools fine but will not heat. Why?
That usually points at the reversing valve, its solenoid, or the control signal that tells it to switch modes. Low refrigerant charge can also show up as weak heat first. We test the valve and the charge on site.
How often should a heat pump be serviced?
Twice a year is reasonable since a heat pump runs in both seasons. We check refrigerant charge, coil condition, airflow, defrost operation and electrical connections. Regular filter changes between visits do more than most homeowners expect.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form. We ask what changed, when it started, and what the thermostat reads. That short conversation tells us whether you need a visit today or tomorrow morning.
- Step 2
We diagnose on site
A technician checks the thermostat, the electrical side, airflow through the filter and ducts, and the equipment itself. We find the actual cause instead of swapping parts and hoping the noise goes away.
- Step 3
You decide before we work
We explain what failed, what the repair involves, and what we would do if it were our own house. Nothing gets replaced until you say go. Then we test the system before leaving.

Why homeowners call us
- Old houses and new onesWe are used to century-old homes with retrofitted ductwork and 1970s subdivisions with original returns. Tight crawl spaces, low basement headroom and odd attic runs are normal parts of the day for us, not surprises that stall the job.
- Built for the swingsHumid summers push AC systems hard and January freezes expose weak igniters and cracked flues. We repair for both extremes across the region, so the fix holds when the weather turns instead of failing the first hard week.
- Air conditioning and heating bothAir conditioner repair in July, heating repair in January, and the IAQ and airflow problems that hide in between. One crew that knows how your cooling and heating share the same blower and the same duct system.
- Plain talk, no pressureWe tell you when a repair makes sense and when replacement is the honest answer. No scare tactics about your BTU load, no upsell scripts. You get the condition of the system and a clear next step.
