Heat Pump Repair on Long Island

Most heat pump repairs on Long Island cost between $200 and $900 depending on the issue. Capacitor or contactor replacements run $200-$400. Refrigerant leak repairs with recharge are $400-$900. Reversing valve failures and compressor issues are higher. We'll give you the full repair cost upfront before any work begins, and if replacement makes more sense we'll explain that option too.

The most common causes are a failed reversing valve (stuck in cooling mode), a malfunctioning defrost cycle (ice buildup on the outdoor coil), low refrigerant from a leak, a tripped safety sensor, or a thermostat wiring issue. In cold weather, heat pumps rely on a defrost cycle to shed ice. If that cycle is broken, the system drops to backup heat and the bills spike. A diagnostic visit will pinpoint the exact cause.

Yes. We service Mitsubishi (including M-Series and Hyper-Heat), Daikin, Carrier, Lennox, Fujitsu, and LG heat pumps and mini splits. Mitsubishi and Daikin are the most common brands we see on Long Island because of their cold-climate performance. We carry common parts on the truck so most repairs finish in one visit.

Yes. Cold-weather heat pump issues are actually when we get most of our repair calls. Common cold-snap failures include iced-up outdoor coils (a defrost cycle problem), refrigerant charge issues that only show up in extreme cold, and sensor failures. We dispatch for these year-round. If your heat pump is struggling below 10-15F, that's often a sign the system is undersized for the home or the defrost cycle needs calibration.

As a general rule, if your heat pump is over 12 years old and the repair costs more than half the price of a new system, replacement usually makes more financial sense. Newer cold-climate heat pumps are significantly more efficient and qualify for PSEG Long Island and NYSERDA Clean Heat rebates that can offset a lot of the replacement cost. We always give you both options with pricing so you can decide.

Our heat pump tune up covers refrigerant pressure check, electrical connection tightening, contactor and capacitor inspection, coil cleaning (both indoor and outdoor), condensate drain line clearing, defrost cycle verification, and a full operational test in both heating and cooling modes. A proper tune up extends equipment life and catches most problems before they become repair calls.

Yes. Mini split repair is one of our most common service calls on Long Island. We handle all major ductless brands and common mini split issues, including indoor unit not cooling or heating, communication errors between indoor and outdoor units, drain line clogs causing water leaks from the wall-mounted head, remote control pairing issues, and refrigerant charge problems.
