In Deltona, your heat pump barely gets a rest
Your heat pump works almost every day of the year here. Cooling from March through November, then heat back on by December, with only a short break between. That is nine months of the compressor cycling on hot afternoons near 91°F, and three more months running the reverse cycle on nights near 50°F. Most systems built for a climate like this handle the load fine, but there is no long off-season for parts to sit idle and no easy stretch to catch a problem before the next season needs the system again.
Volusia County has logged 27 damaging wind events over the past ten years, and statewide, more than a third of households lost power for at least a day in 2024. A heat pump that loses power mid-cycle and comes back on to a tripped breaker or a stuck contactor is a common call after a storm. If your system ran fine before an outage and won't start now, that is usually where to look first.

Florida requires HVAC contractors to hold a state license.
The Construction Industry Licensing Board tests contractors before they get that license, and it keeps a record of who holds one. The license belongs to the contractor, not to any single job, so the same license is what's supposed to stand behind the work whether it's a new install or a repair like this one.
A heat pump repair almost always means opening the refrigerant side of the system, and federal law requires an EPA Section 608 certification for that part of the job no matter what state you're in. In Florida that certification sits alongside the state license rather than replacing it. Between the two, the contractor working on your heat pump is accountable both for holding the license the state checked and for the certification the refrigerant work itself requires.

- Why is my heat pump blowing cold air?
- In heating mode, a heat pump is running the reverse of your air conditioner, so the air coming out feels cool next to your skin even when it's working right. That air is still warmer than the air already in the room, and it will warm the house over time. If the air feels cold rather than just cool, or the house isn't warming up over an hour or two, the system may be stuck in cooling mode, low on refrigerant, or the reversing valve may not be switching over. A contractor can check the valve and the charge and tell you which it is.
- Why is there ice on my heat pump?
- A little frost on the outdoor unit during a defrost cycle is normal on cold nights, and your winter lows here average 50°F, so heavy icing shouldn't be a regular thing. The unit defrosts itself on a timer, melting that frost off automatically. If you're seeing thick ice that doesn't clear, or ice building up again within a few hours, the problem is usually low refrigerant, a dirty outdoor coil, or a fan that isn't moving air the way it should. Any of those keeps the coil colder than it needs to be, and a contractor will need to find which one it is.
- Why is my heat pump running but not cooling?
- If the unit is running but the house isn't cooling down, start with the filter. A clogged filter blocks airflow across the indoor coil and can ice it over, and once that happens the system moves very little cool air no matter how long it runs. If the filter is clean, low refrigerant or a failing compressor are the next likely causes, and both need a contractor to diagnose since they call for gauges and training to check safely. With afternoons here reaching 91°F, a system that's lost its cooling capacity will fall behind fast, so it's worth having someone look at it soon rather than waiting.
