Heat Pump Repair in Falls Church, VA

Heat Pump Repair in Falls Church, Backed by Service Since 1959

Heat pumps maintain a steady indoor climate throughout the seasons by cooling in the summer and heating in the winter. Because these units handle both tasks, a single mechanical failure can disrupt heating or cooling. Issues such as refrigerant leaks, failing reversing valves, or defrost malfunctions can hamper performance in either operating mode.

At Richards Heating & Air Conditioning Co., Inc., we have been diagnosing and repairing residential heating and air conditioning systems since 1959. Our technicians evaluate the indoor air handler, outdoor unit, thermostat controls, and operating mode to determine what is preventing the system from working properly. Whether your heat pump is struggling to switch modes or has stopped working entirely, we identify the cause and explain the repair it needs.

Heat Pump-Specific Problems

The reversing valve changes refrigerant-flow direction to switch the system between heating and cooling. When this valve fails, your system might cool properly but fail to heat, or vice versa. Stuck reversing valves or failed solenoid coils may require replacement to restore both operating modes. We can identify whether the valve itself or the solenoid is the source of the problem before any parts are ordered.

Defrost controls manage ice buildup on the outdoor coil during heating operation. When outdoor temperatures drop and humidity is present, frost accumulates naturally, and the defrost cycle temporarily reverses operation to melt it. If the defrost controls fail, ice can build up unchecked, blocking airflow, reducing heating capacity, and eventually placing strain on other components. We test the defrost controls and related electrical components to identify the failure.

Diagnosing Poor Heating Performance

Low refrigerant reduces the system’s heating capacity and can eventually damage the compressor if the heat pump continues running that way. Refrigerant leaks can be difficult to detect during winter, when outdoor coils operate at low pressures and temperatures. We measure the charge, locate leaks, and check superheat and subcooling values to determine how refrigerant is moving through the system.

Your comfort also depends on how well the auxiliary or emergency heat performs. Heat pumps commonly rely on electric resistance backup during a Northern Virginia cold snap or when the primary system fails, though some homes use a gas or oil furnace instead. If this backup heat doesn’t engage, your home may struggle to stay warm. We test auxiliary heat operation, thermostat settings, and the control boards that coordinate the heat pump and backup system.

Emergency Heat Pump Service

A heat pump failure during a winter freeze or sweltering July afternoon can quickly make your home uncomfortable. We offer rapid repair service when the system stops entirely or performs so poorly that it disrupts daily comfort.

We arrive prepared to diagnose urgent failures. If a required component isn’t immediately available, we can often provide a temporary repair to restore basic heating or cooling while waiting for the part. We also carry common replacement parts for many repairs.

Repair or Replace: What to Expect After a Heat Pump Diagnosis

Once we’ve identified the problem, we’ll walk you through the available options. Not every heat pump issue requires immediate replacement, and some repairs may not be the best long-term solution. We consider several factors, including:

• System age: Older equipment may be closer to the end of its service life.
• Failed component: Some repairs are relatively straightforward, while others can be more involved.
• Repair history: Frequent or recurring repairs may indicate a larger issue.
• Current performance: Poor efficiency or difficulty maintaining comfort can factor into the decision.

Repair may make sense when:

• The failed component is relatively straightforward to replace.
• The system still has useful service life remaining.
• The repair history doesn’t show recurring problems.

Replacement may be worth discussing when:

• The heat pump is aging.
• The system has required multiple repairs in a short period.
• The equipment can no longer meet your household’s comfort needs efficiently.

We won’t push you in either direction. We’ll explain the repair, its expected value, and what continued operation could look like so you can make an informed decision for your home. If replacement makes sense to consider, we can explain those options as well.
