We treat heating repair with the same measured process as cooling: test the thermostat call, verify the heat strips or heat-pump heat mode, meter the electrical components, and check airflow before condemning parts. Emergency heat that smells like burning for a minute is usually dust on the strips after a long idle — but heat that won't come on at all, or a heat pump stuck in icing mode on a cold night, deserves a same-day visit.
Heating problems we fix
- Heat pump runs but blows cool or barely warm air
- Heat strips never engage on the coldest mornings
- Burning smell from vents on the first heat of the season
- Outdoor unit ices over and never defrosts
- Thermostat shows heat on but nothing happens
- Breaker trips whenever heat starts
- Air handler hums but the blower never moves air
- Emergency heat runs constantly and bills spike

How Florida homes make heat
Most Stuart homes heat one of two ways. Electric heat strips inside the air handler work like a giant hair dryer — simple, effective, and hard on amperage when strips or their sequencers fail. Heat pumps move heat instead of making it, which is far more efficient down to about freezing, at which point the heat strips take over as auxiliary or emergency heat.
Each system fails differently. Heat strips burn out or their sequencers stick; heat pumps suffer defrost-board failures, reversal-valve faults, or charge problems that only show up in heat mode; and both can be defeated by a thermostat wired or configured wrong. We meter all of it — amp draw on the strips, defrost-cycle timing, temperatures across the coil — so the repair addresses the actual failure.
The cold-snap surge, and how we handle it
There's a predictable pattern every winter: the forecast shows a front, and within 48 hours heating calls multiply across the county. Systems idle since March choose the coldest night to reveal a dead sequencer. We prioritize by severity — homes with infants, seniors, or health concerns first — and we hold capacity for cold-snap weeks so our Stuart customers aren't waiting days for heat.
A few checks you can do before calling: confirm the thermostat is in heat mode with the setpoint above room temperature, check that the breaker and air handler switch are on, and replace a heavily loaded filter — restricted airflow trips high-limit controls and shuts heat down. If the breaker trips again after one reset, leave it off and call us.
When heating problems signal a bigger issue
A heat pump that ices repeatedly, runs long cycles without warming the house, or leans on emergency heat every cold snap isn't just a winter nuisance — those are signs of low charge, a failing defrost system, or an undersized unit, and they're costing you on summer bills too. We diagnose heat-mode performance the same way we verify cooling, and a bad finding in January often explains a chronic comfort complaint in July.
If the air handler is original to a 1990s or early-2000s home — common in Rio, Golden Gate, and other mid-century neighborhoods — corroded heat strips, worn bearings, and obsolete parts are real possibilities. We'll give you the repair cost and a replacement scope side by side when the decision is close, in writing, with no pressure either way.
Our Heating Repair process
Test first, document everything, and get your sign-off before the work happens — no guesswork, no surprises.
- 1
Verify the call for heat
Thermostat mode, setpoint, wiring, and configuration — a surprising share of no-heat calls end at the thermostat, not the equipment.
- 2
Meter the heat strips
Amp draw against nameplate reveals dead strips, stuck sequencers, and undersized electrical service on the spot.
- 3
Test heat-pump heat mode
We verify reversing-valve operation, defrost timing, coil temperatures, and charge in heat mode — not just cooling mode.
- 4
Check airflow and safety controls
A loaded filter or weak blower trips high limits and shuts heat down; we confirm airflow before approving any part replacement.
- 5
Repair, verify, and advise
After the fix we re-measure temperatures and amp draw, then note what to watch for before the next front arrives.

Heating Repair FAQs
In a Florida home the heating system sits idle most of the year, and dust settles on the heat strips and in the ductwork. The first heat of the season burns that dust off and produces a brief smell that should fade within minutes. If the odor persists, smells electrical, or accompanies smoke, shut the system off and call immediately.
