Nine months of cooling, three of heat, and storms in between
Your air conditioner is the machine doing the real work in Zephyrhills. It runs March through November, nine months a year, against summer afternoons that average 91°F. That is a long season of the compressor cycling on and off, and it is what wears down a system before its time. You notice it as warm air from the vents, or the unit running longer than it used to just to hold the house at a set temperature.
Winter is short here, just December through February, with nights averaging 50°F. The furnace or heat pump does not get the workout the air conditioner does, but most homes here heat with electricity, so when it does run, a weak part shows up fast. Add in the storms that come through, 32 damaging wind events over the past ten years, and the power outages that follow. Over a third of Florida households lost power for a full day or more in 2024. When the power comes back, most systems restart on their own. If yours does not, that is worth a call.

Florida requires HVAC contractors to hold a state license.
Florida runs this through the Construction Industry Licensing Board, which tests contractors before they can hold the license and keeps a record of who holds one. The license belongs to the contractor, not to any single job, so the same license that let them take on a kitchen remodel is the one that lets them work on your furnace or your AC.
For a repair like this, that license is what stands behind the person in your house. Florida does not split this into separate checks for separate kinds of work. The same license covers the whole job, whatever part of your system needs the work.

- Why is my heat not working?
- Most homes here heat with electricity, so start with your breaker panel. A tripped breaker or a thermostat set to cool instead of heat causes more no-heat calls than anything wrong inside the unit. If the breaker is fine and the thermostat is set right, the heat strips or the heat pump itself needs a contractor to look at it, especially with nights averaging 50°F here in December through February.
- Why is my system running but not cooling the house?
- Check your air filter first. A filter clogged with dust blocks airflow across the coil, and the system will run without bringing the house down. If the filter is clean, look at the outdoor unit. Leaves or grass clippings packed against the coil stop it from releasing heat, and on afternoons near 91°F that alone can keep a house from cooling. If both of those check out, the system likely needs a contractor, since low refrigerant or a failing compressor won't show themselves from outside the cabinet.
- What can I check before calling for HVAC repair?
- Check the thermostat setting and batteries, the breaker for the system, and the air filter. Those three catch a real share of no-heat and no-cool calls on their own. Look at the outdoor unit too, and clear away anything piled against it. If the system still isn't working after that, a licensed contractor will need to diagnose it, and Florida requires that license for anyone doing the repair.
