Top-rated independent heating and cooling across Palm Beach County and the Treasure Coast
Nothing But Cold Air
You set the thermostat to heat, and nothing happens. No warm air, no hum from the outdoor unit, maybe a click and then silence. In Florida that usually shows up on the first cold snap in months, after the system has spent the whole year cooling. We handle heating repair and heater repair for homeowners across the region, and no heat is one call we get in waves.

What "no heat at all" actually tells us
No heat is different from weak heat. Weak heat means the system is running and losing the fight. No heat means something in the chain never started, so we work backwards along that chain: the thermostat asks for heat, a control board accepts the call, and the heating stage energises. Break any link and you get nothing. Most Florida homes use a heat pump or electric strip heat, so the usual suspects are electrical rather than combustion. If you do have gas heat and you smell gas, leave the building first, call 911 or your gas utility from outside, then call us. Never troubleshoot a gas smell yourself.
Cause family one: the call for heat never left the wall
This is the cheapest family and the one worth ruling out before anything else. Dead thermostat batteries, a schedule that quietly reverted, a system switch left on cool, or a setpoint below room temperature all produce total silence. We also see thermostats that lost their common wire after a previous job, so they run on battery until the battery dies. Smart thermostats add another wrinkle: a firmware update or a lost wireless connection can leave the display lit while nothing is being sent to the equipment. If a fresh set of batteries and a setpoint bumped up a few degrees brings the system to life, you just fixed it.
Cause family two: power and protection devices
Heat strips and heat pumps pull hard, and Florida coastal air is rough on the parts that carry that load. A tripped breaker, a blown fuse in the disconnect, or a failed contactor stops everything. On older island properties we regularly find corrosion inside the outdoor disconnect and on the strip heat terminals, where salt has eaten the connection down to a thread of metal. You can look at your panel and reset a breaker once. If it trips again, stop and call us. Repeated tripping means something downstream is drawing current it should not, and resetting it over and over is how small problems turn into burnt wiring.
Cause family three: the equipment locked itself out
Modern systems refuse to run when a safety trips, and that refusal looks exactly like a dead system. A clogged filter or blocked return can overheat the strip heat and open a limit switch. A defrost board that failed after years of constant runtime can hold a heat pump off. Low refrigerant charge on a heat pump means the reversing valve has nothing to move, so the unit calls but never warms. What you can safely do: change the filter, confirm supply and return vents are open, and clear leaves, mulch and lawn clippings back from the outdoor unit. Then let it try again.
What we do that you cannot do at home
We put meters on it. A technician reads voltage at the disconnect, amp draw on each heat strip, and control voltage at the board to see whether the call is arriving. On a heat pump we check refrigerant pressures, reversing valve operation and defrost sequence, and we look at the sequencers that bring strip heat on in stages. We also inspect for the corrosion that our salt air causes, because a clean-looking wire can be gone inside the insulation. If your system has gas heat, we test the ignition sequence and flue with instruments. Call us for air conditioning repair or heating repair anywhere we serve, and tell us what the thermostat is doing when we book.
FAQ
Below are the questions homeowners ask us most on a no-heat call, along with straight answers.
Nothing But Cold Air — common questions
My breaker keeps tripping when I turn the heat on. Can I just keep resetting it?
No. Reset it once. If it trips again, leave it off and call us. A breaker that trips repeatedly is reacting to a real fault, and forcing it back on risks damaged wiring or a burnt connection.
Why does my heat pump blow cool air when I ask for heat?
Usually a stuck reversing valve, a failed defrost board, or low refrigerant charge. It can also happen briefly during a normal defrost cycle. If cool air continues past a few minutes, the system needs a technician with gauges.
Does a dirty filter really stop heat completely?
It can. Restricted airflow lets strip heat overheat, which opens a safety limit and shuts the heating off entirely. Change the filter, confirm vents are open, and give the system time to reset before calling.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form with what you hear, smell or feel. Warm air, ice on the lineset, a humming outdoor unit. That detail helps us load the right parts before we drive out.
- Step 2
We diagnose on site
We check the thermostat, the air handler, the condenser and the electrical side, then measure what the system is actually doing. You get a plain explanation of the fault and the repair options before we start.
- Step 3
We repair and verify
Once the repair is done we run the system and confirm temperature split, drainage and airflow at the vents. If a part is on order, we tell you the timeline instead of leaving you guessing.

Why homeowners call us
- We plan for salt airCoastal humidity and salt eat coils, contactors and cabinet screws. We look for corrosion during every visit and treat it as part of the diagnosis, not an afterthought, so a repaired system does not fail again in the same spot.
- Built for constant runtimeFlorida systems run most of the year, so bearings, capacitors and drain lines wear faster than the manual suggests. We size repairs around that reality and point out the components likely to be next in line.
- Old houses and new onesIsland properties often hide ductwork in tight, damp spaces, while tract homes tend to have short, undersized returns. We have worked both and adjust the approach rather than forcing one standard fix.
- Clear talk, no upsell theatreWe tell you what failed, what it takes to fix it, and whether repair or replacement makes more sense for the age of the equipment. If a repair will hold, we say so and get on with it.

- Straight answersWhen a replacement beats a repair, we tell you, sometimes before we roll a truck.
