A heat pump is one of the most efficient ways to heat and cool your home—until it stops working. If your heat pump won’t turn on, you may be left wondering what went wrong and how to fix it. While some issues can be resolved with basic troubleshooting, others require professional attention. Here’s what to check before you call us to schedule heat pump service in Wrightsville, GA.
Check the Thermostat
Your thermostat is the control center of your heating and cooling system. If your heat pump won’t turn on, start by verifying that the thermostat is set correctly. Make sure it’s on “heat” or “cool” mode, depending on the season, and that the temperature setting is below (for cooling) or above (for heating) the current room temperature. If your thermostat runs on batteries, replace them to rule out power issues. If you have a smart thermostat, ensure it’s connected to Wi-Fi and functioning properly. If the thermostat appears responsive but the system remains inactive, the issue may stem from a reversing valve or control board problem disrupting proper function.
Inspect the Power Supply
A heat pump that won’t turn on may not be receiving power. Check your home’s electrical panel for a tripped breaker or a blown fuse. Reset the breaker if necessary, but if it trips again, do not attempt to reset it repeatedly—this could indicate an electrical issue requiring professional repair. Additionally, make sure the heat pump’s power switch, typically located near the indoor or outdoor unit, is turned on.
Examine the Air Filter
A clogged air filter can prevent proper airflow, which may cause your heat pump to shut down as a protective measure. Locate your air filter and check for excessive dust and debris. If the filter is dirty, replace it with a clean one and see if your system resumes normal operation. Premier Heating & Air recommends changing your air filter every one to three months to maintain optimal performance.
Look for Outdoor Unit Issues
Your heat pump’s outdoor unit needs to be free from obstructions to function correctly. Leaves, dirt, ice, or snow buildup can cause performance issues or prevent the system from turning on. If you notice ice accumulation on the coils, do not attempt to chip it away this can damage the unit. Instead, call a professional for safe and effective de-icing solutions. What may look like ice buildup could also be normal steam from heat pump defrost, especially in colder weather.
Check for Faulty Components
Heat pumps rely on several internal components to operate, including capacitors, contactors, and relays. If any of these parts fail, the system may not turn on. Diagnosing and replacing electrical components requires specialized knowledge and should only be handled by an experienced HVAC technician.
When to Call a Professional for a Broken Heat Pump
If you’ve gone through these troubleshooting steps and your heat pump still won’t turn on, it’s time to call the professionals at Premier Heating & Air. Here are a few signs that you need expert repair services:
- The breaker continues to trip when you try to turn the heat pump on.
- You hear unusual noises, such as clicking, buzzing, or grinding, when attempting to start the unit.
- The outdoor unit is frozen or covered in ice.
- Your heat pump turns on but does not produce warm or cool air.
- You suspect an issue with wiring, the capacitor, or another electrical component.
Attempting DIY repairs on your heat pump can be dangerous and may void manufacturer warranties. Instead, let the trained professionals at Premier Heating & Air diagnose and fix the issue safely. Before you consider a do-it-yourself fix, it’s important to understand why repairing a heat pump on your own can be risky and ineffective.

Frequently Asked Questions
Question: What should I check first if my heat pump will not turn on?
Answer: Start by checking the thermostat settings to ensure it is set to the correct mode and temperature. You should also verify that the system has power by checking circuit breakers and confirming the thermostat batteries are not depleted.
Question: Can a tripped breaker cause a heat pump not to start?
Answer: Yes. A tripped circuit breaker can prevent the heat pump from receiving power. Resetting the breaker may restore operation, but repeated tripping can indicate an electrical issue that should be inspected by a professional.
Question: Do thermostat problems prevent a heat pump from turning on?
Answer: Thermostat issues can stop a heat pump from operating properly. Incorrect settings, dead batteries, or wiring problems can prevent the system from receiving the signal to start heating or cooling.
Question: Can a dirty air filter stop a heat pump from working?
Answer: A dirty air filter can restrict airflow and cause the system to overheat or shut down as a safety measure. Replacing the filter can sometimes restore normal operation and prevent further system strain.
Question: When should I call for service if my heat pump will not turn on?
Answer: If basic checks like thermostat settings, power supply, and filter replacement do not solve the issue, professional service is recommended. Ongoing startup problems may signal electrical, mechanical, or safety control issues.
