Tampa's subtropical climate means heating is rarely top of mind — until a cold front drops temperatures into the 30s and a system that's been sitting idle for months suddenly needs to perform. Florida building codes require every residence to maintain a functional heating source, and heat pumps that handle year-round cooling carry that responsibility on both ends.
Expert Home Service provides complete heating repair, heat pump service, pre-season tune-ups, and emergency heating response across Tampa Bay. Veteran-owned, 4.9-star rated across 1,500+ Google reviews, and available 6 AM–11 PM, 7 days a week — including during Tampa's cold snaps when heating failures happen most.
Call (813) 632-8889A heat pump that's been running as an AC all summer has never been asked to switch into heating mode. Reversing valves, auxiliary heat strips, and defrost controls all sit unused for months — and problems only surface when you need heat for the first time. A fall tune-up catches those issues before they become a cold-night emergency.
The reversing valve is the component that allows your heat pump to switch between cooling and heating modes. When it fails, your system gets stuck in one mode — most commonly cooling — and can't provide heat no matter what the thermostat says. It's the single most common heat pump heating failure in Florida.
Failures typically stem from an electrical fault in the solenoid coil, a mechanically stuck internal piston, internal refrigerant bypassing through worn seals, or a loss of pressure differential due to a refrigerant leak. Some reversing valve issues — specifically failed solenoid coils — can be repaired without replacing the entire valve. Mechanical internal failures require full valve replacement, which involves recovering refrigerant, brazing out the old valve, and recharging the system.
System cools when set to heat, or heats when set to cool — can't switch on command.
Warm but not hot air often signals the valve is partially shifting or internally leaking.
A hissing sound from the compressor area can indicate refrigerant bypassing through a worn valve.
You hear the thermostat signal but the system doesn't switch — points to a faulty solenoid coil.
Many Tampa homeowners skip heating maintenance because the system rarely gets used. That's exactly the wrong approach. A heat pump that runs year-round for cooling accumulates twice the operational stress of a single-season system — and components left idle all summer can fail quietly before you ever ask them to heat.
For Tampa's climate, the answer is clear. Here's how heat pumps and furnaces compare across the factors that matter most to Florida homeowners:

Yes. Florida's mild winters make heat pumps highly efficient — they transfer ambient heat from outdoor air instead of generating it with expensive electric resistance strips, using up to 50% less electricity for heating. In summer, a heat pump cools your home identically to a traditional central AC. For Tampa homeowners, it's the most cost-effective year-round HVAC solution available.
For Tampa's climate, a heat pump is the clear choice. Furnaces are designed for northern climates with prolonged freezing winters. Tampa's brief, mild cold season makes heat pump technology far more practical and cost-effective — you get both heating and cooling in one unit, without the need for gas lines or the high operating cost of electric resistance heat strips.
Yes. Florida building codes and landlord-tenant statutes require residential dwellings to have a permanent, functional heating facility capable of maintaining a minimum indoor temperature — typically around 68°F — to meet legal habitability standards. For most Tampa homes, the heat pump that handles cooling year-round also satisfies this requirement.
The most common signs are: the system getting stuck in one mode and unable to switch between heating and cooling, lukewarm air in heating mode despite the thermostat being set correctly, a hissing sound near the outdoor compressor, or clicking at the thermostat signal without the system changing modes. If you notice any of these during a cold snap, call (813) 632-8889 for diagnosis.
If your current system is over 10–12 years old and relies on electric heat strips for winter warmth, upgrading to a high-efficiency heat pump will significantly reduce your year-round energy costs. Our technicians will walk you through an honest cost-benefit assessment on-site. Financing is available through Wisetack. See our system replacement page for more.
A heating emergency includes complete loss of heat during a cold snap — especially when temperatures drop below 40°F — suspected refrigerant leaks, sparks or burning smells from the unit, or a sounding carbon monoxide alarm. Expert Home Service is available 6 AM–11 PM, 7 days a week for urgent heating calls across Tampa Bay. Call (813) 632-8889 for immediate dispatch.
