Florida winters may be mild, but that doesn’t mean your heat pump gets a break. In fact, winter is when many homeowners unknowingly make mistakes that reduce efficiency, increase energy bills, and lead to unexpected breakdowns. At 1st Call Air Conditioning & Heating, we see these issues every year—and most of them are completely avoidable.

If you rely on a heat pump to keep your home comfortable during cooler months, understanding these common pitfalls can save you money, extend your system’s lifespan, and prevent the need for emergency heat pump repair.

Mistake #1: Ignoring Routine Heat Pump Maintenance

One of the biggest mistakes Florida homeowners make in winter is assuming their heat pump doesn’t need maintenance because it works year-round. Heat pumps run in both cooling and heating modes, which means they experience more wear than traditional HVAC systems.

Skipping professional maintenance can lead to:

1. Reduced heating efficiency

2. Higher energy bills

3. Poor airflow and uneven temperatures

4. Unexpected system failures

Scheduling seasonal maintenance allows professionals to inspect electrical components, refrigerant levels, coils, and the reversing valve—key parts that ensure your heat pump switches smoothly into heating mode.

Mistake #2: Constantly Adjusting the Thermostat

Unlike gas furnaces, heat pumps work best when maintaining a steady temperature. Frequently turning the thermostat up and down during winter forces the system to work harder, often triggering the auxiliary heat mode—which consumes significantly more energy.

For Florida homes, the best practice is to:

1. Set a consistent, comfortable temperature

2. Avoid large temperature jumps

3. Use a programmable or smart thermostat for gradual adjustments

This simple change can reduce strain on your system and lower your monthly energy costs.

Mistake #3: Relying Too Much on Auxiliary (Emergency) Heat

Many homeowners don’t realize when their heat pump switches to auxiliary heat. While it’s designed to help during colder snaps, relying on it too often leads to skyrocketing energy bills.

Auxiliary heat should only activate when:

1. Outdoor temperatures drop unusually low

2. The heat pump cannot meet heating demand alone

If your system uses auxiliary heat frequently during mild Florida winters, it may be a sign you need professional heat pump repair. Issues like dirty coils, refrigerant leaks, or airflow problems could be reducing efficiency.

Mistake #4: Neglecting Air Filter Changes

Dirty air filters are a year-round problem, but they’re especially damaging in winter when airflow is critical for proper heating. Clogged filters restrict air movement, causing the heat pump to run longer and harder than necessary.

We recommend:

1. Checking filters monthly

2. Replacing them every 1–3 months, depending on usage

3. Using the correct filter type for your system

This small habit improves indoor air quality and helps prevent unnecessary service calls.

Mistake #5: Assuming Strange Noises or Smells Are “Normal”

Heat pumps may sound slightly different in heating mode, but loud noises, grinding, buzzing, or burning smells are never normal. Florida homeowners often delay calling for service, assuming the issue will resolve itself.

Ignoring warning signs can turn minor issues into major repairs. If you notice anything unusual, it’s best to contact a trusted local professional right away. Searching for heat pump repair near me can help you find experienced technicians who understand Florida’s climate and heat pump systems.

Mistake #6: Waiting Too Long to Schedule Heat Pump Repair

Delaying service is one of the most costly mistakes homeowners make. What starts as reduced efficiency can quickly escalate into compressor damage or complete system failure.
