Heat pumps behave differently from a furnace, and they get misdiagnosed constantly. Serving all of Montgomery County, MD.
A heat pump is the same machine running in two directions, and that's exactly why it gets misread. A homeowner feels air that's warm but not hot and assumes something is broken. In heating mode a heat pump delivers air well below what a gas furnace produces, and that's normal operation, not a fault. The real faults look different.
What actually goes wrong is defrost control, the reversing valve, a charge that has drifted, an outdoor coil packed with debris, or auxiliary heat strips that have taken over because the heat pump isn't keeping up. Property Renovators Home Services runs these calls across Montgomery County through both seasons, with 10 years in business and 20 years of trade experience behind the standard, and the first job is always separating normal heat pump behavior from an actual failure.
Before calling anything broken we confirm what the system should be delivering at the current outdoor temperature. Half of heat pump complaints are a system doing exactly what a heat pump does.
We run it in heating and in cooling and take readings in each. A reversing valve problem hides completely if you only test one mode.
Strip heat will keep a house warm while the heat pump underneath it's failing. If the strips are carrying the load, the bill tells the story before the thermostat does.
That includes watching a defrost cycle where defrost is the suspected fault, because that's the only honest way to prove it.
We're based in Gaithersburg and cover the whole county. The heating and cooling side runs every day of the week, 8am to 7pm, Saturday included.
