Heat Pump Repair Service FAQs
How long does a heat pump repair usually take?
Most standard heat pump repairs can be completed in one visit, often within a few hours. More complex issues may require ordering parts, but we always keep you informed about timelines.
Should I repair or replace my heat pump?
If your system is relatively new and the repair is minor, fixing it is usually the most cost-effective option. However, if your unit is over 10–15 years old and requires frequent repairs, replacement may offer better efficiency and long-term savings.
Why is my heat pump running but not heating or cooling?
Common causes include low refrigerant, thermostat issues, a malfunctioning reversing valve, or airflow restrictions. A professional inspection is the best way to determine the exact cause.
How can I prevent future heat pump problems?
Routine maintenance is the best way to prevent heat pump repairs. Scheduling regular tune-ups helps identify worn components early, improve efficiency, and reduce the risk of unexpected breakdowns.
Why is my heat pump blowing cold air?
If your heat pump is blowing cold air when it should be heating, you should first check the thermostat. Make sure your heat pump is set to heating mode and that the set temperature is higher than your home’s current temperature. If that doesn’t fix the problem, your heat pump may be going through a normal defrost cycle, which can temporarily affect the temperature of the air coming from your vents. Other possible causes include dirty air filters, low refrigerant levels, or a malfunctioning reversing valve. If your heat pump continues blowing cold air, schedule professional heat pump repairs with our team to identify and resolve the issue.
Is it normal for my heat pump to ice up?
It’s normal for some frost to form on your heat pump’s outdoor unit during Charleston’s colder winter mornings, especially when humidity levels are high. Your heat pump should automatically enter a defrost cycle to melt this frost and maintain efficient operation. However, if thick ice builds up, doesn’t melt, or prevents your system from heating properly, you may have an issue with the defrost controls, airflow, or refrigerant levels. If this happens, reach out to us for heat pump repairs in Moncks Corner and the surrounding areas.
