Why Does My Clute, TX, Heat Pump Blow Cool Air When the Heat is On?

February 25, 2022

When it’s running as it should, your heat pump offers better efficiency and lower costs than a standard furnace in Clute, TX. However, if you’ve noticed that it’s blowing cool air even though it’s running in heating mode, read on to learn some reasons why this is happening and what to do about it.

You Recently Converted From a Furnace

If you converted from a furnace to a heat pump this year, you’re likely expecting more heat from your vents. A heat pump works differently than a furnace, so the air isn’t heated as high as a furnace.

Heat pumps run longer than furnaces to supply heat because they don’t produce heat but simply transfer it. That means that what’s coming from your vents won’t be as warm as what you were used to with a furnace. Professionals use a detailed equation to make sure the system is producing the right amount of heat.

The System Is in Defrost Mode

Your system has an automatic defrost mode to prevent damage to the coils if it freezes. The compressor shuts off, but the fans continue to run while this mode is active, allowing the coils to thaw.

While the mode is active, it’ll feel like your air is cooler. This should only last about 10 minutes.

You Have a Stuck Reversing Valve

The reversing valve is what allows your heat pump to switch from cooling to heating. If the valve is failing or faulty, it’ll get stuck and won’t switch over. If you suspect this may be the problem, call a professional for heat pump repair services.

The System Needs Maintenance

Your HVAC system slowly collects airborne contaminants on the indoor coils. This begins affecting the system’s heating ability by restricting airflow and creating a kind of insulation on the coils. If you haven’t had maintenance recently, then your system may simply need the cleaning that’s included with these visits.
