Winter is here, and you’re relying on your heat pump to keep your home warm and cozy. But what happens when it starts blowing cold air instead? It’s not only uncomfortable but also concerning. A heat pump blowing cold air in heat mode is a common issue that homeowners face during the colder months.
In this blog, we’ll discuss what causes a heat pump to blow cold air in heat mode and what you can do to fix it. So put on your fuzzy socks, grab a cup of hot cocoa, and let’s get started!
Check the Thermostat
If your heat pump is blowing cold air in heat mode, then one of the possible reasons could be your thermostat. A lot of times, people do not realize that their thermostat settings are not correct, leading to such issues. Check if the thermostat is set to the right mode – heat, cool, or auto.
If it is set to cool, then the heat pump will blow cold air irrespective of the mode selected. Also, ensure that the temperature set on the thermostat is appropriate for the heat mode. If it is too low, it means that the heat pump will struggle to heat the space, leading to cold air blowing out.
To avoid any confusion, it is best to refer to the thermostat manual or contact a professional to guide you through the right procedures. By checking the thermostat settings and ensuring that they are correct, you can prevent your heat pump from blowing cold air in heat mode.
Make sure the thermostat is set to heat mode and the temperature is set correctly.
When winter hits, it’s time to crank up the heat and stay comfortable indoors. However, before you reach for that thermostat, make sure it’s set to heat mode and the temperature is set correctly. It sounds simple, but many people forget to make this important check before resorting to more drastic measures.
A thermostat set to cooling will just send cool air through your home, and a thermostat set to the wrong temperature won’t effectively heat your home either. When you’re looking for that perfect temperature, remember to be realistic. A setting of 80 degrees might make you feel toasty, but it will also make your energy bill skyrocket.
A more reasonable temperature of 68-72 degrees will keep you comfortable and save you money at the same time.
Check the Air Filter
If your heat pump is blowing cold air in heat mode, one of the first things you should check is the air filter. A clogged or dirty air filter can restrict airflow and cause the heat pump to malfunction. It’s important to clean or replace the air filter regularly, especially during peak usage months.
A good rule of thumb is to check the filter at least once a month and replace it every three months. Additionally, a dirty filter can cause your system to work harder, leading to higher energy bills and potentially damaging the unit in the long run. So, be sure to prioritize air filter maintenance to keep your heat pump functioning properly.

Doing so can help improve the airflow, increase fuel efficiency, and prolong the life of your engine. A good rule of thumb is to check the air filter every 12,000 miles or so, or more frequently if you drive in dusty or polluted areas. If you’re not sure how to do it, consult your owner’s manual or take it to a professional mechanic.
Taking care of your air filter is a small yet significant step in making sure your vehicle stays healthy and runs smoothly for years to come.
Check the Outdoor Unit
If your heat pump is blowing cold air in heat mode, there might be an issue with the outdoor unit. The outdoor unit in a heat pump is responsible for pulling in heat from the outside air and transferring it to the indoor unit, which then distributes it throughout your home. If the outdoor unit isn’t working properly, the heat transfer won’t happen, and you’ll be left with cold air blowing inside.
There are a few reasons why your outdoor unit might not be working as it should. One common issue is a dirty or clogged air filter. If the air filter is dirty, it can restrict airflow to the outdoor unit, which makes it harder for the unit to pull in heat from the air outside.
Another possibility is that the outdoor unit is covered in ice or snow, which can also keep it from working correctly. If you’re experiencing this issue with your heat pump, start by checking the air filter and cleaning or replacing it if necessary. If that doesn’t solve the problem, take a look at the outdoor unit to see if there’s any ice or snow buildup.
If there is, turn off the heat pump and allow the ice to melt before trying again. If neither of these solutions works, it’s best to call in a professional to diagnose and repair the issue.
Ensure that the outdoor unit is free from debris and that the coils are not frozen.
When it comes to maintaining your HVAC system, it’s important to pay attention to the outdoor unit as well. This is the part of the system that is exposed to the elements and can become clogged with debris like leaves, dirt, and grass clippings. To ensure that your system runs efficiently and effectively, you should make sure that the outdoor unit is free from obstructions.
In addition, you should check the coils to make sure that they are not frozen. This can be a sign that there is a problem with the refrigerant going through the system. By checking on the outdoor unit regularly, you can prevent problems from occurring and keep your HVAC system running smoothly.
Remember, a well-maintained system will save you money in the long run, so it’s worth taking the time to check on it regularly.
If the coils are frozen, turn off the system and allow them to thaw before turning it back on again.
When your AC system fails to cool your home, it’s time to check the outdoor unit. One reason for a malfunction could be due to frozen coils. If you notice ice forming on the unit, turn it off and let it thaw before turning it back on again.
Ice blocks the air flow to and from the unit, making it unable to remove heat from your home. Another issue could be a dirty or clogged filter. A filter that’s clogged up with dust and debris causes the unit to work harder and longer, decreasing its efficiency and lifespan.
Clean or replace the filter to avoid this problem. Finally, inspect the area around the outdoor unit. Ensure that there are no obstructions like leaves or branches that can block air flow.
Proper air flow is vital for efficient cooling. So, the next time your AC isn’t keeping your home cool, check the outdoor unit for these common issues.
