Your heat pump in Waynesboro, VA should create a cool and comfortable environment when it’s in cooling mode. However, a variety of issues may prevent the system from doing so. Below, we’ll explain some potential heat pump problems that can cause your system to blow warm air in cooling mode.
A Faulty Reversing Valve
Unlike other HVAC systems, heat pumps can both cool and warm your home. In heating mode, the system’s refrigerant absorbs heat from the surroundings and brings it in to warm your indoor air. When cooling, the fluid absorbs heat from your indoor air and releases it into the environment.
The component that makes the refrigerant flow in the opposite direction is the reversing valve. If this valve breaks, it won’t change the refrigerant’s direction. Essentially, your system will be stuck in the mode it was in when the valve broke, which might explain a lack of cool air coming from your vents.
Dirty Coils
When pollutants, such as dust and debris, accumulate on the system’s coils, they create a barrier that makes it difficult for the refrigerant to absorb or expel heat from the indoor air. To address this problem, schedule maintenance services regularly so technicians can clean your coils.
A Dirty Air Filter
Your system pulls air in through a filter within your home. That filter prevents particulates from making their way into the system, which also helps improve the quality of your indoor air. Over time, though, those particulates can build up and prevent air from flowing freely into your heat pump.
Consequently, your system might work harder than necessary, or you might not get any cool air at all. Check your filter monthly, and replace it as necessary. You’ll often find that replacing it every 2-3 months or so is ideal.
Fortunately, professional technicians can address the underlying issues and restore your system’s efficiency. You can call the heat pump experts at Valley Air Heating, Cooling & Plumbing for all your air conditioning needs.
