Heating in North Central Florida is a part-time job for your system — which is exactly why it sometimes fails on the first cold night. Here is how to troubleshoot.
First steps
Confirm the thermostat is set to heat and above room temperature. Replace a dirty filter. Check the breaker. A faint burning smell on first use is usually just dust burning off idle elements and clears in a few minutes.
Heat-pump specifics
If a heat pump runs but does not warm the house, it may be low on refrigerant, stuck in a defrost cycle, or leaning heavily on auxiliary heat. Frequent "emergency heat" use is a sign something needs attention rather than a normal mode to leave it in.
When to call
No heat during a freeze is worth a prompt call — emergency service is available after hours. Persistent burning smells, repeated breaker trips, or gas-system faults should be checked right away.
