Heat Pump Repairs: Refrigerant Leaks

Discover the versatility of heat pumps in the mild winters of the Southwest—they function as both cooling and heating systems. This dual capability is achieved through a refrigerant cycle and a reversing valve. However, it’s crucial to note that systems using refrigerant, like heat pumps, may be susceptible to leaks. These leaks can harm the system and compromise its ability to maintain home comfort. Learn to identify signs of a refrigerant leak with these tips to ensure your system’s optimal performance.

How the Heat Pump Works

Similar to a standard split central air conditioner, a heat pump evaporates refrigerant in the evaporator coil to extract heat. The heated refrigerant is then transferred outside to the condenser coil, where it is condensed, releasing the absorbed heat outdoors. This cycle repeats until the desired indoor temperature is achieved.

In contrast to a central AC, a heat pump has the ability to reverse the refrigerant flow and switch the function of its coils. This allows the system to extract heat from the outdoor air and use it to warm the indoor air—an efficient process that doesn’t involve generating new heat. However, insufficient refrigerant levels can lead to operational issues.

Watch out for these signs of a refrigerant leak:

1. Short Cycling: If your HVAC system starts up but quickly shuts down, it could be short cycling. This strains the system and can cause lasting damage. Insufficient refrigerant can lead to overheating as the system struggles to meet heating or cooling demands.

2. Hissing Sounds: Strange hissing noises from your heat pump may indicate refrigerant escaping. No, it’s not a snake—it’s the sound of pressurized gas leaking from the system.

3. Increased Costs: Don’t settle for overpriced heating! If your heater is becoming expensive to run, it might be due to a refrigerant leak in the system. Keep an eye out for potential leaks to maintain efficient and cost-effective operation.
