Heating and Furnace Repair in Hudson and West Pasco

Florida heating is its own problem. Your heat runs a few dozen hours a year, sits untouched for the other eight months, and then has to work on the coldest night of the season with no warning. That is why heating calls here cluster into about three weeks of the year, and why almost every one of them could have been caught in October.

Mauro’s Air Conditioning & Heating repairs, replaces and maintains heat pumps, air handlers and electric heat across Pasco, Hernando and Pinellas counties. Repair diagnostic is $79. Estimates on new equipment are free. Licensed in Florida, CAC1818179.

Most people genuinely do not know, and the answer changes everything about what a repair costs and what your bill should look like. In this part of Florida it is almost always one of two things.

A heat pump with electric backup. This is the overwhelming majority of homes in Pasco and Hernando. The outdoor unit that cools you in July runs backwards in January to bring heat inside. Behind it sits a bank of electric resistance elements in the air handler, called strip heat or auxiliary heat, that switches on when the heat pump cannot keep up. If your outdoor unit runs when the house is heating, you have a heat pump.

An electric air handler with strip heat only. No heat pump involvement at all, just the resistance elements. Common in older homes, additions, and anywhere the original system was replaced cheaply. Your outdoor unit stays silent all winter. This is the most expensive way to heat a house in Florida, and if it describes you it is worth knowing, because a heat pump conversion often pays for itself faster than people expect.

Gas furnaces are rare in west Pasco and we do not service them. If you have gas heat, we will tell you that on the phone rather than send a truck.

Not sure which you have? Set the thermostat four degrees above room temperature, then walk outside. If the outdoor unit is running, it is a heat pump. If the house is warming and the outdoor unit is silent, you are on strip heat.

It is not bad luck and it is not coincidence. It is the single most predictable thing in Florida HVAC.

Your heat side last ran in March. Since then it has sat through seven months of Florida summer in a hot attic or a garage, while the cooling side of the same equipment ran almost continuously. Contactors corrode. Capacitors drift out of tolerance. A defrost board that was marginal in spring is dead by December. Sequencers in the strip heat bank stick. None of that announces itself, because nothing is asking those parts to do anything.

Then the first front comes through, forty thousand households in Pasco County call for heat within the same six hours, and the failures that have been sitting there since spring all surface at once. That is also the night every HVAC company in the county is fully booked, which is the part that actually costs you.

The fix is twenty minutes in October. Set the thermostat to heat, push it four degrees above room temperature, and let it run. You want three things: the system comes on, warm air reaches the registers within a few minutes, and it shuts off cleanly at setpoint. A burnt dust smell the first time is normal and comes from dust that settled on the elements over the summer. It should fade within fifteen minutes. If it does not fade, or you get smoke, shut it off and call.

If any of those three things does not happen, you have found your problem on a seventy-degree afternoon with the whole schedule open, instead of at eleven at night in January.

The diagnostic is $79. That covers a technician coming out, testing the system properly and telling you what is wrong. You get the repair price in writing before anything is done, and nothing starts until you say so.

Estimates on new equipment are free. If the answer is replacement rather than repair, that assessment does not cost you anything.

What we will not do is quote a repair over the phone. Anyone who does is guessing, and the guess is almost always low enough to get the truck in your driveway and high enough to make up for it once they are there. The honest version is that heating faults in Florida range from a $200 part to a system that is not worth fixing, and nobody can tell which from a description of the symptom.

What you will get from us is both numbers side by side. The repair cost, the replacement cost, and what we would do in your position and why.

A heat pump in heating mode is doing something genuinely clever, and there are a handful of specific ways it goes wrong. These are the faults we actually find.

• Reversing valve stuck or failed. The valve that flips the system between cooling and heating. When it sticks you get cold air on a heat call, or a system that heats only when it feels like it. The valve itself is not expensive. The labor to get at it is.
• Defrost control board failure. In cold damp weather the outdoor coil frosts, and the board is what decides to melt it. When the board fails you either get a unit that ices solid and stops producing heat, or one that defrosts constantly and burns strip heat every cycle. Either way the bill tells you before the comfort does.
• Low refrigerant charge. A system low on refrigerant will still cool acceptably in July and completely fail to heat in January, because heating is the harder job. The strips quietly cover the gap every cycle and the only symptom you ever see is the power bill. This is the most commonly missed heating fault in Florida.
• Failed auxiliary heat relay or sequencer. Either the strips never come on, so the house will not get warm on a cold night, or they never shut off, which is expensive in a way you notice about thirty days later.
• Thermostat wiring and configuration. A heat pump thermostat has to be configured as a heat pump. We regularly find smart thermostats installed with the wrong system type, running strip heat as the primary heat source all winter because nobody set a single menu option.

Steam rolling off your outdoor unit on a cold morning is normal, by the way. That is a defrost cycle working correctly. A unit encased in ice that never clears is not.

Short answer: below roughly forty degrees your heat pump stops being able to carry the house on its own and hands the work to electric resistance strips, which cost around three times more per hour to run.

A heat pump does not make heat, it moves it, which is why it delivers roughly three units of heat for every unit of electricity. Strip heat makes heat directly, which caps it at one to one. It is the same physics as the difference between a hair dryer and a refrigerator running backwards. Nothing is broken when this happens. It is the system working as designed.

What is not normal, and what is worth a service call, is any of these:

• The AUX or EM indicator comes on when it is 55 or 60 degrees outside.
• Your thermostat is set to Emergency Heat and nobody remembers switching it. This locks the heat pump out entirely and runs the house on resistance heat alone. It is free to fix and we find it constantly.
• The house cannot reach setpoint on a night in the forties.
• Your bill jumped in a month that was not actually cold.

There is also a thermostat habit that costs people real money here. With a heat pump, a large overnight setback backfires. Drop it eight degrees and the thermostat sees a gap too big for the heat pump to close, so it fires the strips to catch up at six in the morning. You save a little overnight and pay it back with interest. Two degrees is fine. Eight is counterproductive. If your thermostat has an adaptive or intelligent recovery setting, turn it on.

We wrote this up in more detail: why your Florida power bill jumps in January when it barely gets cold.

There is no formula that survives contact with a real house, but there is a reasonable way to think about it, and we would rather you understood it than took our word.

Repair, almost always, if: the system is under twelve years old, the failed part is a capacitor, contactor, relay, sequencer, defrost board or thermostat, and the refrigerant circuit is sound. These are a few hundred dollars and buy you years.

It becomes a real conversation if: the system is twelve to fifteen, or the repair involves the compressor, the reversing valve, or a refrigerant leak you cannot pinpoint. At that point you are spending meaningful money on equipment whose remaining life is uncertain.

Replacement is usually the honest answer if: the compressor has failed on a system past twelve, the coil has a leak that cannot be isolated, or the unit still runs R-22. R-22 was phased out of production, and what remains is expensive enough that a significant leak on an R-22 system rarely justifies the refill, let alone repeated ones.

What we will not do is use a single expensive part as a pretext to sell you a system. If it can be fixed, we will tell you it can be fixed and what that costs. Plenty of our reviews are from people another company told to replace who found out otherwise.

More on installation and replacement if that turns out to be the direction.

A cooling tune-up does not test your heat. Different components, different mode, different failure points. A system can pass a spring visit perfectly and fail on its first heat call in December, because nobody asked it to heat.

What the heating side of a visit covers:

• Reversing valve operation verified in both modes. The only way to know it switches is to make it switch.
• Defrost cycle forced and observed. Not assumed. Initiated and watched.
• Strip heat elements tested individually, with amp draw measured. A bank with one dead element still produces heat, just not enough, and you will never notice until the coldest night.
• Auxiliary heat lockout and staging checked against the thermostat configuration. This is where we catch systems running strip heat as primary.
• Refrigerant charge verified under heating load. A charge that reads fine in cooling can be short for heating.
• Electrical connections torqued. Strip heat pulls serious amperage. Loose lugs are a fire concern, not just an efficiency one.

October and November are the right months for this. Details on our maintenance plan page.
