No two heating systems break the same way, and in Sarasota homes the first question on any no-heat call is what kind of equipment we are dealing with. Gas furnaces most often stall on an oxidized flame sensor. The burners fire, the sensor fails to confirm the flame, and after three attempts the control board closes the gas valve and locks the system out. Cracked hot surface igniters, sticking pressure switches, plugged condensate traps on high-efficiency units, and tired blower motors round out the usual list. Heat pumps have their own failure patterns. A defrost cycle that falls short lets ice build up on the outdoor coil, a bad reversing valve leaves the system stuck in cooling mode, and a dead outdoor unit hands the whole load to the electric backup strips, which cost several times as much to run.
Most of our service calls are for Furnace Repair. That's the place to start if you need a fix today.
Warning Signs for Heating Repair
The sooner you notice these red flags, the easier and cheaper the fix. Keep an eye out for the following clues:
- Some rooms warm while others stay stubbornly cold
- A rotten-egg, burning, or musty smell once the heat kicks on
- The thermostat calls for heat but the vents blow cold air or nothing
- An outdoor heat pump coil that stays iced over
- A furnace that tries to light, clicks, and then quits
- The system starting and stopping every few minutes without warming the house
- A loud boom when the burners light, which points to delayed ignition
- Higher heating bills with less comfort to show for them
Early Action Saves Money
Most HVAC failures start small, a weak capacitor, a squealing blower, a system that runs a little longer each week. Call (941) 203-3680 at the first sign of trouble.
