Common Problems

Heating Services Problems We See in Largo

These are the issues our technicians deal with most often. If something sounds familiar, give us a call.

build

Heat Pump Defrost Cycles

During rare freezing temperatures, heat pumps may ice over. A properly functioning defrost cycle clears this automatically. If ice persists, the defrost board or reversing valve may need attention.

build

Ignition Problems (Gas Furnaces)

Furnaces that sit idle for months can develop pilot light or electronic ignition issues. A pre-season tune-up prevents cold-morning surprises.

build

Reversing Valve Failures

Heat pumps use a reversing valve to switch between cooling and heating. A stuck valve means the system won't heat properly, even if cooling worked fine all summer.

build

Thermostat Issues

Older thermostats may not switch from cooling to heating mode correctly. Smart thermostats eliminate this issue and optimize for Florida's mild heating needs.

How It Works

What Happens When You Call Us

FAQs

Heating Services Questions from Largo Homeowners

helpIs a heat pump or furnace better for Florida?

Heat pumps are typically the best choice for North Central Florida. They provide efficient heating down to about 35°F and double as your AC in summer. Since our winter lows rarely stay below 40°F for extended periods, heat pumps operate at peak efficiency here.

helpWhy does my heat pump blow cool air in heating mode?

Heat pump air feels cooler than furnace air (around 90-100°F vs. 120-140°F from a furnace), but it's still warming your home. If the air feels cold or the system runs constantly without warming the house, call us—you may have a refrigerant issue or reversing valve problem.

helpHow can I prepare my heating system for winter?

Schedule a fall tune-up in October or November. We'll verify the system switches from cooling to heating properly, check refrigerant levels, and ensure no problems developed during the summer cooling season.
