Quick Answers: HVAC in North Texas
What is the reversing valve and why does it strand a heat pump?
The reversing valve is the part that lets a heat pump run both ways - it flips refrigerant flow to switch between cooling in summer and heating in winter. When the solenoid coil fails or the valve sticks mid-stroke, the system gets locked in one mode (or stuck somewhere in between), so you might have cooling but no heat, or lukewarm air that never satisfies. We test the coil, check the slide position, and either free or replace the valve to restore both modes.
Why is my heat pump iced over and blowing cold in winter?
In heating mode the outdoor coil runs cold and naturally frosts up; a healthy heat pump clears it automatically with a defrost cycle. If the defrost board, defrost sensor, or reversing valve fails, the unit stays caked in ice, loses heating capacity, and falls back on expensive auxiliary strip heat. We diagnose the defrost board and sensor first - that is the most common winter no-heat call we run in North Texas.
Capacitor, contactor, or compressor - which is it?
A buzzing or no-start outdoor unit is most often a cheap part: a swollen dual-run capacitor or a pitted contactor, both quick same-day fixes. A compressor that hums and trips the breaker, or refrigerant that has leaked low, is the bigger repair. We measure capacitor microfarads, check contactor pull-in, and read refrigerant pressures before quoting, so you are not paying for a compressor when a $20 part would do.
One System, Two Jobs - Twice the Failure Points
A heat pump cools your house in July and heats it in January using the same equipment, which means it works nearly year-round and has parts a straight AC simply does not - the reversing valve and the defrost board chief among them. That extra hardware is exactly where most heat pump calls land: a stuck reversing valve that kills heating, a failed defrost sensor that ices the outdoor coil, a swollen capacitor, a pitted contactor, or a slow refrigerant leak that drags down both modes. We diagnose in heating and cooling, read pressures, and check the electrical components before quoting. If the unit is past its prime, we will be straight with you about replacement versus repair, and a twice-a-year heat pump tune-up heads off most of these failures.
