Why Is My Heat Pump Blowing Hot Air on the Cool Setting

Aug 28, 2019 | Air Conditioning

Is your heat pump blowing warm air on a hot day? Man suffers from heat while working in the office and tries to cool off by the fan.

We at AA-AIR CO., hope you’re enjoying the warm weather this season. Although if you’re reading this article, you might be a bit tired of it. It’s a hot day, yet your heat pump doesn’t want to cooperate and is circulating hot air throughout your house. If this is the case, you probably want to take care of it right away. Here are five reasons your heat pump might be blowing hot air while on the Cool setting:

1. Incorrect Thermostat Settings

Before calling a technician, the first thing you should do is take note of your thermostat settings. Be sure you’ve set your thermostat to Auto or On, as well as Cool. The Fan setting will not cool your house; it simply circulates warm air. Next, be sure you’ve adjusted the thermostat two to four degrees below the current room temperature.

2. Incorrect Thermostat Configuration

Sometimes, due to faulty wiring or a variety of other mishaps, your thermostat may not be correctly communicating with your heat pump. If this appears to be the case, a technician should come to your home and repair it.

3. Clogged Air Filter

When an air filter becomes clogged, this significantly hinders your heat pump’s ability to circulate cool air. Check your air filter. If it’s dirty, replace or clean it (depending on the type of filter). Afterwards, you should quickly notice an improvement in air quality and temperature.

4. Refrigerant Leak

Refrigerant flows through the heat pump’s coils, harvesting hot air from your home and pushing it outside. If your refrigerant is low or empty, your heat pump can’t do its job. Refrigerant is continuously cycled through your heat pump, so the refrigerant doesn’t regularly need to be replaced. However, if the system springs a leak, you have a problem. You should contact your HVAC technician for this repair, as refrigerant is a substance requiring extra care when handled. Additionally, an internal problem with your heat pump may have caused the leak.

5. Duct Leak

Air ducts, especially older ones, are prone to leaking. When your ductwork leaks, it can’t properly disperse the air through your vents plus some of the air you are paying to cool may be going other places like attic or crawlspace. This might make your home feel hot in some spots. If you suspect that you have leaky ducts, call AA-AIR. We can perform a detailed inspection where we’ll be able to give you the best advice on how to repair it.
