What Heating Repair Covers in Lake Mary Homes
Florida homes heat differently than homes up north. About two out of three Florida homes use electricity as their main heat source. In most Lake Mary homes, that means a heat pump with electric backup heat built into the air handler.
Lake Mary has long, humid summers and short, mild winters. Your heat can sit unused for months, then have to work hard the first night a cold front comes through.
We repair every part of that setup:
Heat pumps
The heat pump does most of the heating. It moves heat into your home instead of making it. See our heat pump repair page for more on this system.
Heat strips
These are electric coils inside the air handler. They kick in when the heat pump needs help or during a defrost cycle.
Thermostats
A bad thermostat can look like a dead heater. We check it on every heating call and offer thermostat repair as well.
Signs Your Heat Needs Repair
Heat runs so rarely here that normal sounds and smells can be alarming. Here's how to tell what's normal from what needs a call.
Usually normal
- A light burning smell the first time you turn on the heat. Dust on the heat strips is burning off. It should fade within a few minutes.
- Steam or a light frost on the outdoor unit on a cold morning. The heat pump is clearing ice from its coil.
- A short burst of cooler air during that defrost cycle.
Time to call us
- A burning smell that doesn't fade, or smells like plastic or wiring. Turn the system off and call.
- The breaker trips when the heat comes on.
- No heat or weak heat. The system runs, but the house stays cold.
- The system turns on and off over and over.
- Some rooms warm up and others don't. This can point to a duct or airflow problem.
- Your energy bill jumps during a cold month.
- The system runs nonstop and the house never warms up.
- Your home only gets warm on emergency heat.
- Grinding, banging, squealing or loud buzzing. These sounds often mean a worn or loose part.
- A blank thermostat screen.
Common causes include a faulty thermostat, a clogged filter, a failed part, loose wiring or blocked airflow. We track down the real cause so the fix lasts.

Repair or Replace Your Heating System?
Many heating problems come down to one failed part, and fixing it gets your heat back on.
Sometimes a new system makes more sense. It may be time to replace yours if it's over 10 to 15 years old, needs frequent repairs, or can't keep your home warm. If that's the case, we'll tell you straight.
We offer free estimates on new systems and ductwork. We install Rheem and American Standard systems, and every new install comes with a free UV light kit. We also offer a price match guarantee on new systems.
Financing is available through Wisetack, and qualifying homes can use the Florida P.A.C.E. Program.
See our new system pricing page, or read about heat pump installation.

Heating Repair FAQs
Is a burning smell normal when I turn on my heat?
A light burning smell the first time each season is usually dust burning off the heat strips. It should fade within a few minutes. If it lasts, gets stronger or smells like plastic or wiring, turn the system off and call us.
Should I switch my thermostat to emergency heat?
Only if your heat pump stops working. Emergency heat shuts off the heat pump and runs only the electric heat strips. It keeps you warm, but it costs more to run. If you need it to stay warm, your heat pump likely needs repair.
Why is my outdoor unit steaming on a cold morning?
That's usually the defrost cycle. On cold, damp mornings, ice builds up on the heat pump's outdoor coil. The system melts it off, which makes steam. If the unit stays covered in ice, call us.
