4 Reasons Why Your HVAC Unit is Overheating
February 23rd, 2021 by alexys
You use your HVAC unit throughout the year to maintain a comfortable temperature. It helps regardless of if it’s the middle of winter or you’re in a heatwave. Over time, some issues can occur if the system doesn’t get the attention or care it needs. If the HVAC unit starts to overheat, there are a few causes to look at. Make sure you can hire an HVAC technician to perform these repairs.
1. Dirty Air Filters
Clogged air filters are one of the most common reasons HVAC systems overheat and fail. Homeowners often forget to replace the filter. This leads to a lack of airflow and cause the parts to work harder each time you heat or cool the home. It’s important to replace or clean the air filters every two months. It all depends on how often you use the system each season.
2. Dirty Coils
If you didn’t get your HVAC system maintained every year, then it can cause the parts to become dirty. This leads to them not working. Dirty coils prevent the parts from releasing enough heat. This causes the appliance to work too hard and leads to overheating.
Proper ventilation should prevent the coils from having issues. It also reduces the risk of overheating. The most common sign that this is the cause is if you notice the appliance has difficulty cooling the home.
3. Refrigerant Leaks
HVAC units can overheat if there’s not enough refrigerant present. The refrigerant helps to cool down the appliance. It won’t do its job right if a leak is present. Avoid repairing the leak without a technician’s help. This is to avoid accidents that can occur. A technician will know how to find the leak. They will perform the repairs to get the system back up and running.
4. Grimy Blades
The blades may also collect too much dirt and grime if they aren’t wiped down every few months. The blades can have a hard time moving if they’re covered in gunk. This causes the HVAC system to work harder to run. If your HVAC system is struggling to operate, you can expect it to overheat. Clean the parts and wipe everything down at least every six months to avoid repairs.
