No overtime fees. Ever.
Heat pump work is different from standard furnace or AC repair because the system does both jobs through one refrigerant cycle, and a misstep on one side ripples through the other. A refrigerant leak that looks like a cooling problem in July often traces back to a reversing valve that was already wearing out in February. Our technicians carry factory certifications on major brands including Trane, Daikin, Mitsubishi, Bosch, and Amana, and they run a full diagnostic before recommending any repair. What drives cost on a heat pump job is usually the failed component itself: a capacitor swap is a quick fix, a compressor replacement is a larger investment, and the age of the system matters when you're weighing repair against a new heat pump installation. Every job is different, so contact Brick Street Plumbing Heat & Air for an accurate estimate.
Common Heat Pump Problems We Fix
Most heat pump failures come down to a handful of components. Here's what our techs find most often in Loudoun County homes.
Reversing Valve Failure
The reversing valve switches the system between heating and cooling mode. When it sticks or leaks, you get a unit that blows lukewarm air regardless of the setting. It's one of the more common heat pump failures and not something a homeowner can safely test without refrigerant gauges.

Refrigerant Leaks
Low refrigerant means the system can't move enough heat in either direction. Ice on the outdoor coil in summer, weak heating in winter, and higher electric bills are the usual signs. We locate the leak, repair it, and recharge to the correct level for your unit's specifications.

Capacitor and Contactor Issues
Capacitors start the compressor and fan motors. A failed capacitor is one of the fastest repairs we make, and it's often what separates a unit that won't start from one that needs a full compressor. We also cover AC capacitor replacement as part of a broader heat pump diagnostic.
Defrost Cycle Problems
In winter, heat pumps defrost their outdoor coils automatically. If the defrost board or sensors fail, ice builds up on the coil and efficiency drops to near zero. Loudoun County's cold snaps are exactly the conditions that expose this failure mode.
Thermostat and Control Board Faults
Comfort complaints often aren't the heat pump at all. A miscalibrated thermostat or a failing control board can make a perfectly good system behave erratically. We verify the controls before we touch the mechanical components, because replacing a part that isn't broken wastes everyone's time.
Blower Motor and Fan Failures
Indoor and outdoor fan motors move air across the coils. A sluggish or failed blower means the heat exchange stops working even if the refrigerant circuit is fine. Unusual squealing or grinding is usually the first sign, well before total failure.
Repair vs. Replace

Our Process
How a Brick Street Heat Pump Diagnostic Works
Full System Inspection
We check refrigerant pressures, electrical components, coil condition, reversing valve operation, and airflow before reaching any conclusion about what's failed. A symptom like 'not heating' has a dozen possible causes and we find the actual one.
Straight Explanation of Findings
Before we touch a part, we explain what we found, what it will take to fix it, and whether that repair makes sense given the system's age and condition. You make the call with complete information.
Repair Completed Same Visit When Possible
Our trucks carry common components for major brands. Most capacitor, contactor, sensor, and control board repairs finish the same day. Compressor or coil work on older or less common units may require a parts order, and we'll give you a clear timeline.
Why Heat Pumps Need Loudoun County Expertise
Heat Pump Maintenance Keeps Repair Bills Lower
The heat pump failures we see most often were preventable. Annual maintenance catches failing components before they cascade.
- Coil cleaning extends compressor life
- Dirty coils force the compressor to work harder, shortening its lifespan measurably.
- Refrigerant checks prevent coil freeze
- Catching a slow leak early costs a fraction of the repair after ice damage occurs.
- Defrost system verification before winter
- A board or sensor that's degrading in October will fail during the first hard freeze.
- Electrical checks protect expensive components
- Weak capacitors and loose connections are cheap to address and costly to ignore.
