Heating Repair in Lake Worth, FL
South Florida cold snaps are short, but a heating system that fails on one of them is miserable. We fix heat mode.
Heat that works the few nights you need it
Most Lake Worth homes heat with electric heat strips in the air handler or with a heat pump that reverses its cooling cycle. Because these systems are used a few nights per winter, failures often go unnoticed until the first cold front and then show up all at once on a 45-degree night.
Heat-mode problems include a failed heat strip or sequencer, a tripped limit switch, a reversing valve that does not switch and a thermostat set wrong for the season. Many of these are simple to test, and we can usually tell you quickly whether the issue is a part or a setting.

Signs your heating needs repair
- The thermostat is set to heat and the air stays cool
- The heat comes on but only blows lukewarm air
- The outdoor unit runs in heat mode but the house does not warm
- You smell burning dust the first time heat comes on
- The breaker trips when the heat starts
- The system short-cycles in heat mode

Heating Repair questions answered
Do I really need heat in Florida?
Not often, but cold fronts can drop temperatures into the 40s. A working heating mode matters for comfort and for older adults and young children.
Why does my heat smell like burning?
Dust on the heat strips burns off the first time they run after a long break. If the smell persists or smoke appears, turn the system off and call us.
What is a heat pump?
A heat pump is an air conditioner that can reverse its cycle to move heat into the house. It uses a reversing valve to switch modes.
Can you fix a furnace?
Please call and describe the equipment first. Most Florida homes use electric heat, and we will confirm if we can service what you have.
