When your air conditioner isn’t working right, it can be frustrating, especially in the heat of summer. The good news is, many common issues can be easily fixed with some basic DIY knowledge. Problems like weak airflow, odd sounds, or inadequate cool air can often be resolved with a few simple steps.
This guide will walk you through diagnosing and fixing your AC issues, helping you keep your home cool without breaking the bank. At Putnam Mechanical, in Mooresville, NC, we’re happy to help with more serious problems, but these quick fixes can save you a significant amount of money.
Check Your Thermostat Settings
When your air conditioner isn’t working right, your thermostat is one of the first things to check. Sometimes, it’s a simple mistake like the thermostat being set to heat instead of cool. Take a glance at your settings to ensure the mode is set correctly. If the thermostat is set correctly, but you’re still not getting the cooling you need, it could be that it is out of calibration.
In that case, adjusting or replacing it might be necessary. Another thing to check is the temperature setting. If set too high, the system might not cool your home effectively. Consider lowering it by a few degrees and seeing if that does the trick.
If your thermostat isn’t working properly, try resetting it. Turn it off, wait a few seconds, then turn it back on. This can help clear any temporary errors or glitches. Also, check the batteries if your thermostat runs on them. Low battery power can sometimes cause erratic behavior and incorrect temperature readings. If the problem persists, consider a more advanced thermostat with better sensors, like a smart thermostat, to help you manage your AC more efficiently.
Check the Air Filters
A clogged air filter is one of the most common reasons air conditioners fail to perform as expected. When the air filter gets dirty, it restricts airflow, which can cause your system to overheat and even freeze up. This is something you can easily check and fix yourself. Simply locate the filter, which is usually behind a panel near the return air duct, and remove it. If it’s covered in dust, dirt, or debris, it’s time for a cleaning or replacement.
If you have a reusable filter, clean it thoroughly by washing it with water and letting it dry before reinstalling it. For disposable filters, replace them with a new one. When purchasing a new filter, buy the correct size for your system. Most air filters need to be replaced in 1–3 months.
Examine the Air Vents
Another simple DIY fix is to check the air vents throughout your home. If some areas are warmer than others, it could be due to blocked or closed vents. Walk around your home and ensure all the vents are open and unblocked by furniture or other obstructions. Sometimes, furniture or curtains can block airflow, making it harder for your AC to cool the room. Even small objects like rugs or décor can prevent the air from flowing freely.
Once you’ve confirmed that the vents are open, check for visible dust that might be clogging the vent. You can easily clean vents by using a vacuum cleaner with a brush attachment. Cleaning the vents helps to improve airflow, making your AC system more effective.
If the vents look clean but your AC still struggles, it might be worth checking the ductwork. Leaky or disconnected ducts can seriously impact your system’s performance. If you suspect an issue with your ducts, consider calling an AC repair professional to inspect and seal them.
Clear the Condenser Unit
The outdoor condenser unit is another important part of your air conditioning system that often gets overlooked. Dirt, leaves, and debris can build up around the condenser, making it harder to release heat.. Clear the area around the condenser to keep your AC running smoothly.
