5 Heat Pump Problems Encountered in the Summer

When the weather gets hot, your household relies on its heat pump to cool your home. That’s why it can become much more noticeable when something goes wrong during this time, and there are some specific heat pump problems that seem to happen more often in the summer. The extra heat can put more pressure on your unit, causing it to malfunction in a variety of ways. Knowing what heat pump problems to look out for in the summer can help you to catch them early on.

If you do find that you’re suffering from a heat pump issue in the summer, it’s best to call a professional. Professionals like Entek are able to repair small and large issues with your heat pump all year round and perform maintenance on it so that these problems are few and far between. To help you prepare for the issues that may arise when the weather changes, here are a few of the heat pump problems you may encounter in the summer.

1. Strange Smells

Have you noticed that your home has a strange smell in the summer? This could be caused by your heat pump. Heat pumps are known to give off odors if there’s an underlying problem within the unit. Though not always a cause for concern, contacting a professional when you notice a strange smell in your unit can be helpful. Depending on the smell, you might have a bigger problem on your hands.

One smell that people report coming from their heat pump in the summer is a musty smell. That smell is usually caused by mold building up in the unit. Condensation occurs when your unit is running, and without the proper drainage, your unit becomes the perfect environment for mold to grow. Though that mold may not affect how well your unit runs at first, it could be affecting the air quality in your home, which may lead to health issues.

 A burning smell is another issue that people have with their heat pumps in the summer. This could be caused by your unit overheating itself, due to not having good airflow to properly cool it. If these or any other strange smells start to occur with your heat pump, a professional like the staff at Entek will be able to properly fix it.

2. Increased Noise

An increase in noise from your heat pump can be cause for concern. You’ve probably become used to the typical sounds that come from your heat pump, so when you start to think that it’s a little noisier than usual, it probably is. Heat pumps don’t typically become a lot louder for no reason, so it’s best to figure out where the noise is coming from and address it as soon as possible.

The extra noise from your unit could be coming from a few different places. Sounds like a clang or bang could be an issue with your fan and should be addressed sooner than later. Loud vibrations could hint at something being loose within the system. If the noise level increases significantly, calling an HVAC specialist to help you with the problem is best.

3. Freezing Up

Having your heat pump freeze up in the summertime isn’t something you’d typically expect. With the hot temperatures that come in the summer months, it seems almost impossible for anything to freeze. Still, this is a pretty common heat pump problem for the summer, and it can end up causing other problems as well.

When heat pumps freeze in the summer, it’s not the whole unit that’s frozen. The heat pump coils are the thing that will experience this, and if you know anything about coils, you know how important they are to your unit. With frozen heat pump coils, the rest of your unit will have to work twice as hard, using up more energy and producing lackluster cooling results.

There are a few reasons why your heat pump coils may be freezing. Being low on refrigerant is a popular answer. When you’re low on refrigerant, the pressure in your system drops, causing the coil to grow colder. Another issue could be that your system has poor airflow due to dirty air filters, which prevents warm air from hitting the coil and preventing freezing.

4. Running Constantly

If your heat pump is running constantly in the summer, it may not be working to its full potential. An efficient heat pump will be able to heat your home properly, without having to work at all hours of the day. If your heat pump is overworking itself, you’ll notice it when your energy bills become much higher.

Your heat pump may be running constantly simply because you’ve set your thermostat too low. If your thermostat temperature is at an unrealistic number, your heat pump will be constantly trying to attain that temperature. Set your thermostat accurately and check it every once in a while to make sure no one bumped it accidentally.

Another reason your heat pump could be running constantly is that your filters are dirty. When your filter is clogged, your heat pump will have to work harder to cool your home as it pushes through the dirty filter. Checking the filter and replacing it often can help to avoid this problem.

5. Not Cooling

If your heat pump isn’t sufficiently cooling your home in the summer, it won’t take you long to notice. A decrease in efficiency with your unit can mean high temperatures in your home that you want to have fixed right away. Sometimes, these problems are just starting in the summer, and other times, they’ve been progressing throughout the previous seasons.

There are many possible causes for why your heat pump isn’t cooling your home properly in the summer. It could be something as small as a dirty filter or as big as faulty wiring. Keeping up with maintenance is a good way to avoid this issue at times when you need your heat pump the most.With proper maintenance, done semi-frequently, you can avoid these issues causing your heat pump to stop working. Specialists like Entek have a maintenance program that you can join, which gives you peace of mind while professionals keep track of your warranties and scheduled maintenance checkups. Regular maintenance can help you to avoid all of the issues that heat pumps face during the summer.
