Heat Pump Maintenance and Repairs

Like any HVAC system, heat pumps need regular attention to perform at their best and avoid unexpected breakdowns. Understanding common maintenance and repair needs helps you protect your investment and maintain consistent comfort.

South Shore Mechanical is here to help you with:

• Filter changes and cleaning. Indoor air filters require replacement or cleaning every one to three months, depending on usage, while outdoor unit coils need periodic cleaning to remove dirt, leaves, and debris that restrict airflow and reduce efficiency.
• Refrigerant level checks. Low refrigerant levels diminish heating and cooling capacity and may indicate a leak in the system that needs professional repair to prevent compressor damage and restore proper performance.
• Defrost cycle issues. During cold weather, heat pumps periodically enter defrost mode to remove ice buildup on their outdoor coils. However, when this cycle malfunctions, ice accumulates excessively, blocking heat transfer.
• Reversing valve failures. The reversing valve switches your heat pump between heating and cooling modes, and when it sticks or breaks, your system may blow cold air in winter or fail to cool in summer.
• Thermostat calibration. Improperly calibrated thermostats cause your heat pump to cycle incorrectly, run continuously, or fail to maintain your desired temperature, wasting energy and reducing comfort.
• Compressor problems. Strange noises, reduced output, or complete system failure often trace back to compressor issues that require immediate professional diagnosis to prevent total system breakdown.

Regular maintenance visits catch small problems before they become costly repairs, keeping your system running efficiently throughout every season.
