Heat Pump Repair in Dunedin, FL
A heat pump handles both cooling and the occasional chilly night in Dunedin, so when it falters you feel it year-round. Nolan Air repairs heat pumps throughout 34698, from the older homes near downtown to newer construction around Alternate US-19. We’re veteran-owned and locally operated, licensed in Florida (CAC1819932), with technicians who come from our nearby Palm Harbor shop.
Heat pump repairs are scheduled Monday–Friday, 8:00 AM–7:00 PM; evenings and weekends depend on availability. Call (727) 353-9293.
Warning Signs
- Weak heating on cold mornings or weak cooling in summer
- Thick ice on the outdoor coil that doesn’t melt off
- Frequent use of backup or emergency heat strips
- Clicking without startup, or loud buzzing
- Higher electric bills with no change in use
- Constant cycling or never reaching set temperature
Two-Way Diagnosis
Because a heat pump reverses its refrigerant flow, our technicians test it in both modes. They check the reversing valve and solenoid, defrost board and sensors, refrigerant pressures, compressor and fan motors, capacitors and contactor, auxiliary heat strips and the thermostat’s staging. After pinpointing the problem, they explain it and give you a quote before starting.
Typical repairs include defrost controls, reversing valve coils, outdoor fan motors, capacitors, contactors, blower motors and refrigerant leak repair. If replacement would make more sense, we’ll show you why and let you decide.
Dunedin-Specific Wear
Heat pumps near the water age faster. Salt carried off St. Joseph Sound and from Honeymoon Island coats coils and wiring along Edgewater Drive and surrounding streets, leading to corrosion, leaks and failed connections. Inland, live oaks and overgrown hedges can smother outdoor units and choke airflow.
Indoors, many Dunedin homes — older bungalows and 1970s–90s block homes alike — have air handlers in attics where summer heat stresses blower motors and the backup heat strips. Tight attic access in historic cottages can make repairs slower, so we plan for it.
Fast Local Dispatch
Our Palm Harbor shop sits about 15 to 25 minutes from most Dunedin addresses across north Pinellas. Let us know about gates, parking near the Pinellas Trail or downtown, and where the indoor unit is when you book.
Keeping It Running
A heat pump works more hours than an AC-only system, so regular maintenance pays off. Ask about our Dunedin tune-ups, which cover heat pump defrost and reversing valve checks.
Understanding Backup Heat
Most heat pumps in Dunedin have electric heat strips in the air handler that kick in when the outdoor unit can’t keep up or during defrost. They are useful on the few genuinely cold mornings each winter, but they use far more electricity than the heat pump itself. If your thermostat shows auxiliary or emergency heat running often on mild days, something is wrong — a failing defrost control, a refrigerant leak, a bad sensor, or a thermostat that is staged incorrectly. Catching it early prevents a painful power bill. During a repair visit, we check that the strips, sequencers and limit switches work safely, since overheated strips in a hot attic can create a fire risk. We also confirm that thermostat settings fit the equipment, which is a common oversight after a homeowner replaces a thermostat on their own. A few setting changes sometimes solve what looked like a major failure.
Heat Pump FAQs — Dunedin
Why does my heat pump blow cool air in heat mode?
It may be defrosting briefly. If it continues, a stuck reversing valve, low charge or failed defrost board could be the cause.
Is ice on the outdoor unit normal?
Light frost that clears quickly is normal. Heavy ice that stays usually signals an airflow, refrigerant or control problem.
Does being near the water shorten heat pump life?
It can. Salt corrosion is common near Edgewater Drive; rinsing and inspection help.
Repair or replace an old heat pump?
We weigh age, refrigerant type, condition and repair cost and give you both options.
What should I check before calling?
Confirm the thermostat mode, check the filter and breaker, and note any error codes.
