With the summer months approaching, many homeowners are starting to think about their air conditioning units and making sure they are in proper working order. However, air conditioning repairs can be costly, with the average repair costing around $300-$500. This is why many people are turning to DIY fixes to save money and keep their AC units running smoothly. In this article, we will discuss some common AC unit problems and how you can fix them yourself to save money.
Common AC Unit Problems
1. Dirty air filter – One of the most common problems with AC units is a dirty air filter. A dirty air filter can cause your AC unit to work harder and less efficiently, leading to higher energy bills and potential damage to the unit. To fix this issue, simply remove the old filter and replace it with a new one. Filters are relatively inexpensive and can be found at most hardware stores.
2. Frozen coils – Another common issue with AC units is frozen coils. This can be caused by a number of factors, including dirty coils, low refrigerant levels, or blocked airflow. To fix this issue, turn off the unit and let the coils thaw out. Once they are thawed, check for any blockages or dirt that may be causing the issue. If the problem persists, you may need to call a professional to recharge the refrigerant levels.
3. Leaking refrigerant – Leaking refrigerant is a serious issue that can lead to decreased cooling efficiency and potential damage to your AC unit. If you suspect that your unit is leaking refrigerant, it is important to address the issue as soon as possible. To fix this problem, you will need to locate the source of the leak and seal it. This can be a complex and potentially dangerous task, so it is best to leave it to a professional.
4. Faulty thermostat – A faulty thermostat can cause your AC unit to run erratically or not at all. To fix this issue, check the batteries in the thermostat and replace them if necessary. If the problem persists, you may need to replace the thermostat altogether. Thermostats are relatively inexpensive and can be found at most home improvement stores.
5. Blocked condenser unit – The condenser unit is located outside of your home and is responsible for releasing hot air from your AC unit. If the unit becomes blocked by leaves, debris, or other obstructions, it can lead to decreased cooling efficiency. To fix this issue, simply clear away any debris from the unit and make sure that there is at least two feet of clearance around it.
