Why is my heat pump blowing cool air in the winter?
Usually a reversing valve that has not shifted into heating, a low refrigerant charge, or a thermostat set or wired wrong. Heat pump air also feels cooler than furnace air by nature. We measure temperatures at the coil to tell the difference.
Is frost on the outdoor unit normal?
A light coat of frost in damp weather is normal, and the unit should melt it off in a defrost cycle every so often. Solid ice covering the coil and fan for hours is not normal and points to a defrost control or airflow problem.
What does a defrost cycle problem look like?
You may hear a whoosh and see steam from the outdoor unit as it clears ice, which is correct. Trouble looks like ice that never clears, defrost running constantly, or the unit shutting down on a cold morning.
How does dual-fuel repair differ from a straight heat pump?
A dual-fuel system has to hand off between the heat pump and a gas furnace at a set outdoor temperature. Repairs often involve the changeover control, the outdoor sensor, or thermostat staging rather than the heat pump itself.
How soon can you get to a Poolesville home for AC repair?
Most Poolesville calls get a same-week visit, and we hold slots each morning for homes with no cooling or no heat at all. Call and tell us what the thermostat reads and whether the outdoor unit is running. That usually tells us what to load on the truck before we head out your way.
How it works
- Step 1
Tell us the symptom
Call or fill in the form and describe what changed. Warm air, short cycling, a smell, water near the indoor unit. Details like that help us load the right parts before we leave.
- Step 2
We diagnose the whole system
We check the thermostat, the indoor unit, the outdoor unit and the ductwork, including runs in crawlspaces where damp air and loose joints quietly cause weak airflow and long run times.
- Step 3
You approve the fix
We explain what failed, what it takes to repair it, and what we would watch next season. Nothing gets replaced without your yes, and we clean up before we leave.

Why homeowners call us
- Humidity is our home groundMuggy summers and damp shoulder seasons drive most of the calls we take. We look at moisture and airflow together, not the cooling number alone, because a clammy house often means a sizing or duct problem.
- Crawlspace ducts get checkedOlder homes across the region run supply ducts through vented crawlspaces. Crushed flex, disconnected boots and soaked insulation show up constantly, and we get under the house to look instead of guessing from the register.
- Heating and cooling bothSame crew for air conditioning repair in July and heating repair in January. We know how your furnace, heat pump and air handler share ducts and a blower, so one visit covers the whole system.
- Plain talk on repair or replaceWhen a repair makes sense, we repair it. When a system is failing in ways that will keep costing you, we say so and explain why, then leave the decision with you and your timeline.
