If you’ve moved into a beachside condo from a house inland, you may notice your system works differently in winter. The outdoor unit shuts off when you call for heat, and all your warmth comes from inside. That’s by design.
Reason 1: Salt air is hard on heat pump parts
“I think the best answer for that is the salt water corrosion. With a straight cool air conditioning system, it eliminates the defrost board. It’s not required, and it doesn’t have the reversing valve. So when condos call for heat, they run directly off of their heat strips.”
Jason Healy, Operations Manager
A heat pump relies on a reversing valve to switch between cooling and heating, and a defrost board to clear ice in cold weather. Oceanside, those are exactly the parts salt air attacks.
“Some people do want heat pumps out there, but the corrosive nature of the saltwater air will eat away at the defrost board. It eats away at everything.”

Reason 2: Coatings help, but only so much
Coastal units come with protective coating, and Total Comfort can add more. But no coating makes a heat pump immune to life on the beach.
“We can get coastal units that help prevent that, but the coastal coating only covers, in most cases, just the coil. Sometimes we use an aftermarket weather coating locally called Adsil, where we can fully coat the system. But it never fully prevents the corrosive nature of being oceanside.”

Reason 3: Condos don’t need much heat
With units above, below and beside you, condos hold heat well. That means a small heat strip does the job without running up your power bill.
“Condos are very well insulated, so you don’t need a lot of heat to maintain the inside temperature. The bigger the heat strip, the bigger the amp draw and the more energy you use. In a small condo, you go with a smaller one, like a 5 kilowatt.”

Heat pump vs. AC with heat strips at the beach
| Question | Best fit | Why |
|---|---|---|
| Oceanside condo or beachfront home | AC + strips | Fewer parts exposed to salt air. |
| Inland home in Ormond Beach or Port Orange | Heat pump | Efficient heat where corrosion is less of a factor. |
| You want a heat pump near the water anyway | Possible | Ask about coastal units and full Adsil coating. |
Tips for heating your condo
- Raise the thermostat a few degrees at a time. Your heat strip runs until the room is within about 3 degrees of your setting, then shuts off.
- Expect a light dusty smell the first time. Dust on the strip burns off in a few minutes. Burning plastic is not normal; turn it off and call.
- Lukewarm air means the strip needs a look. See heat strips and sequencers explained.
Call us if
- Your condo heat blows room-temperature air
- You smell burning plastic or see debris from the vents
- You see rust or corrosion on your outdoor unit

Frequently asked questions
Why don’t beachside condos have heat pumps?
Salt air corrodes heat pump parts like the reversing valve and defrost board. A straight AC with heat strips avoids those parts entirely.
Can I put a heat pump in a beachfront condo?
Yes, with a coastal unit and protective coating such as Adsil, but no coating fully prevents salt air corrosion. Ask us about the trade-offs for your building.
What size heat strip does a condo need?
Well-insulated condos usually need a small strip, often around 5 kilowatts. We size it to the space so it heats efficiently.
Is Adsil coating worth it?
It can extend the life of a unit near the water by coating the whole system, not just the coil. It reduces corrosion but doesn’t eliminate it.
