Common Heat Pump Problems We Solve
Heat pumps are complex systems, and when a problem arises, it often presents with clear warning signs. If you are experiencing any of the following issues, it is time to schedule a professional diagnosis.

System Fails to Heat or Cool
This is the most critical sign of a problem. The issue could stem from several sources, including a refrigerant leak, a malfunctioning reversing valve (which switches the system between heating and cooling modes), or a compressor failure. Our technicians will perform a comprehensive diagnostic to pinpoint the exact cause and restore its primary function.
Loud or Unusual Noises
Your heat pump should operate with a relatively low hum. Grinding, squealing, or clanking noises often indicate serious mechanical problems, such as worn-out motor bearings or loose internal components. Ignoring these sounds can lead to catastrophic failure, so it’s crucial to have them inspected immediately.
Frequent or Constant Cycling
Does your heat pump turn on and off every few minutes? This short cycling can be caused by a faulty thermostat, a clogged air filter restricting airflow, or an improperly sized unit. This not only fails to heat or cool your home effectively but also drives up energy bills and puts excessive strain on the system’s components.
Frozen Coils or Refrigerant Lines
Ice buildup on either the indoor or outdoor unit is a clear sign of trouble. This is typically caused by restricted airflow due to dirty filters or blocked vents, or a low refrigerant charge. Operating a heat pump with frozen coils can severely damage the compressor, the most expensive component of your system.
Sudden Spike in Energy Bills
If your utility costs have unexpectedly increased without a change in your usage habits, your heat pump may be losing its efficiency. A struggling system has to work much harder to maintain the desired temperature, consuming more energy in the process. A professional repair can restore its efficiency and bring your bills back down.

Is It Time to Repair or Replace Your Heat Pump?
A common question we hear from homeowners in Mount Pleasant is whether it's more cost-effective to repair an aging heat pump or invest in a new one. As your trusted advisors, we provide honest guidance to help you make the best long-term decision for your home and budget. Consider these key factors:
- Age of the Unit: Most heat pumps have a lifespan of 10-15 years. If your system is approaching or has surpassed this age, investing in a significant repair may not be the most economical choice, as other components may soon fail.
- Cost of the Repair: A widely used guideline is the "$5,000 Rule." Multiply the age of your unit by the estimated cost of the repair. If the total exceeds $5,000, replacement is often the smarter financial decision. For example, a $600 repair on a 10-year-old unit ($600 x 10 = $6,000) suggests that replacement is a better investment.
- Frequency of Breakdowns: If you find yourself calling for repairs every year, those costs can quickly add up. A new, reliable system can provide peace of mind and save you from the hassle and expense of repeated service calls.
- Energy Efficiency: Technology has advanced significantly. A new, high-efficiency heat pump can drastically reduce your monthly energy bills, providing a return on your investment through long-term savings.
Our technicians will assess your current system’s condition and provide a clear, unbiased recommendation based on their findings, empowering you to choose the right path forward.
