Common Heat Pump Problems We Repair in Lexington
System Won’t Heat During Winter
A heat pump that fails to produce heat indicates compressor failure, refrigerant loss, or valve damage. Without heating during winter, your home becomes dangerously cold. Our technicians identify whether the problem is electrical, refrigerant-related, or mechanical, then execute the proper repair to restore heating fast.
System Won’t Cool or Cools Weakly
A heat pump that loses cooling capacity suggests compressor wear, dirty coils, or refrigerant decline. Weak cooling forces your system to run constantly without reaching target temperature. Our NATE-certified technicians inspect all cooling components, clean coils, check refrigerant levels, and replace failed parts.
System Short Cycles On and Off
A heat pump that cycles excessively indicates thermostat malfunction, refrigerant problems, or overheating. Frequent cycling prevents proper temperature control and wastes energy. We diagnose the cause and repair or replace the failed component to restore normal cycling.
Ductless Mini-Split System Won’t Cool or Heat
Mitsubishi ductless and other mini-split systems can fail due to refrigerant leaks, internal coil damage, or compressor failure. Without wall-mounted comfort, individual rooms stay uncomfortable. Our technicians diagnose ductless system problems and complete repairs maintaining efficient zone heating and cooling.
Unusual Noises or Vibration from Unit
Grinding, squealing, or rattling sounds indicate bearing wear, loose parts, or internal damage. Unusual noises typically precede complete failure. Our technicians identify the noise source and repair or replace the affected component before catastrophic breakdown occurs.
Refrigerant Leaks or Declining System Efficiency
A slow refrigerant leak reduces heating and cooling capacity, forcing your system to work harder and use more energy. Rising utility bills often signal refrigerant loss. Our technicians locate leaks using professional equipment, repair the source, and recharge the system to proper levels.

Short cycling occurs when your system cycles on and off too frequently, usually indicating thermostat malfunction, refrigerant problems, or internal pressure issues. Our diagnosis identifies the exact cause so we can fix the real problem rather than guessing or replacing parts unnecessarily.
Signs of low refrigerant include weak heating or cooling output, hissing sounds, frozen outdoor unit, or higher energy bills. Never attempt to add refrigerant yourself. Our technicians locate leaks, repair the source, and recharge your system to proper levels with professional equipment.
Traditional systems use existing ductwork for heat distribution. Ductless mini-split systems including Mitsubishi units mount directly in rooms without ducts. Both require different diagnostic approaches. Our technicians are trained on all heat pump types and handle repairs specific to your system.
Yes. We repair Mitsubishi and other ductless mini-split systems with the same expertise as traditional heat pumps. Ductless systems require specialized knowledge of internal coil operation and refrigerant cycles. Our NATE-certified technicians have that expertise.
We stand behind our heat pump repair work. Our repairs include the quality of our labor and the durability of parts installed. Ask about the specific warranty for your repair when we provide your service estimate.
