Why Is My Heat Pump Blowing Hot Air in Murrieta, CA?

Heat pumps are extremely useful for their ability to function as both heating and cooling systems. However, they should be able to switch seamlessly between their heating and cooling modes, and the failure to do so might leave you in a predicament facing a scorching spring in Murrieta, CA. If your heat pump starts blowing hot air while in cooling mode, here are some possible reasons for the problem:

Reversing Valve Malfunction

Since the reversing valve is the crucial part that enables heat pumps to move between heating and cooling modes, it’ll often be the first thing the service technician checks. If the reversing valve gets stuck in heating mode, your heat pump will continue expelling hot air. You shouldn’t try to fix this, as you could further damage the heat pump.

Refrigerant Leak

Refrigerant is essential to a heat pump’s day-to-day operation regardless of the mode it’s in. If your heat pump is leaking refrigerant, the system will lose at least some of its ability to remove heat from warm indoor air and cool your home. During the typical spring weather in Murrieta, CA, it’ll feel like the system is blowing hot air.

It’s important to note that refrigerant is extremely dangerous. If you notice a hissing noise or the smell of ether, leave your home right away. When you schedule HVAC maintenance, our service technicians will check the refrigerant levels and look for leaks, so you can get these fixed before summer.

Broken Thermostat

Finally, any bizarre behavior your heat pump exhibits may not actually originate from the system itself. Instead, your thermostat, which controls when the system heats and cools, may be responsible. Incorrect or blocked signals may be to blame for the issue.

Your heat pump should work for you this spring in Murrieta, CA, when the temperature can fluctuate wildly. If it works against you by blowing hot air when in cooling mode, call Castillo Heating & Air Conditioning, Inc. and ask for our honest heat pump services.
