Heat Pump Repair McLean VA You Can Count On

01

Heat pump blowing cold air in heat mode

(Our Fix)This usually means a stuck reversing valve or a failed defrost control board. We test the valve with pressure readings, check the board and thermistor, and replace the failed part. Most jobs finish in two to three hours.

02

Outdoor unit frozen solid in winter

(Our Fix)A frozen coil points to low refrigerant or a defrost cycle that never initiates. We thaw the coil safely, find the leak or bad sensor, repair it, and confirm defrost cycles on schedule.

03

System runs but never reaches setpoint

(Our Fix)Low charge, a dirty coil, or duct leaks can all cause this. We measure static pressure with a duct pressure gauge, check refrigerant charge, and seal duct joints with duct sealant to restore airflow.

04

Loud grinding or screeching from the air handler

(Our Fix)That noise is a blower motor or fan motor bearing going out. We shut the system down, replace the motor, and check the wheel for balance so you do not get a repeat failure next season.

05

Water pooling around the indoor unit

(Our Fix)A clogged condensate drain line is the usual culprit, sometimes paired with a frozen coil. We clear the line, flush the pan, and verify the trap is pitched so water drains away from your floor.

“Our heat pump died on the first cold night in November. They had a tech at our door in Chesterbrook within an hour and a half, diagnosed a bad defrost board, and had heat back on before midnight. Fair price, no upsell.”

“I called three companies and these guys were the only ones who picked up at 7 a.m. on a Sunday. The compressor was shot and they walked me through the replacement cost honestly. New unit installed two days later and the house has never been more comfortable.”

“They found a refrigerant leak that two other techs missed. Used an electronic detector and showed me the bubbles at the joint. Repaired it, recharged the system, and my cooling bill dropped noticeably. Good, thorough work.”

“Our mini-split in the home office stopped cooling in July. They cleaned the blower, cleared a clogged drain, and checked the charge in about an hour. Professional, tidy, and they explained how to keep it running between visits.”

“The blower motor was screeching so loud we could hear it from the driveway. They replaced it the same afternoon and balanced the wheel. No more noise, and the airflow is stronger than it has been in years.”

“We manage several rental properties in McLean and these are the only HVAC folks we call now. They show up when they say, invoice clearly, and never try to sell a system when a repair will do. That reliability matters.”
