The Top 5 Most Common Air Conditioner Problems (Plus How to Fix Them)
Don’t get heated up. Your air conditioner is going to break.
But keep a cool head when it does. You should keep the contact information for your local air conditioner repair company, but you can fix many problems yourself. You just have to know what the problems are.
Here are the top five most common air conditioner problems, and how you can fix them.
Be Prepared for Air Conditioner Problems
Buy the tools you need to fix your air conditioner. You will need a wrench, cordless drill, screwdriver, and flashlight.
Turn off the system before attempting any repairs. Have someone spot you and hand you your tools. Place the unit where you can access it easily.
Wear rubber gloves to protect yourself from electric shock. Give yourself time to fix the unit, since repairs may take a couple of hours.
1. Warm Air Flow
There are a few things that cause warm air flow.
Examine how sunlight impacts your outdoor cabinet. Sunlight warms air outside, and ducts carry this air into your home. Moving your cabinet to a shaded area should help.
Examine the seal around your ducts and compressor. Hot air may be flowing in, or cold air may be flowing out. Reapply weather stripping around them.
Go outside and examine your refrigerant and an outdoor compressor. If you hear a hissing sound, they may be leaking. Call your local repair company.
2. Broken Thermostat
Your thermostat measures the temperature outside so the system knows when to activate. Thermostats can break for several reasons.
Check how the thermostat’s heat sensor is aligned. If it is in direct sunlight, put it in a shaded area.
Make sure your thermostat is turned on. Thermostats can turn off by themselves, especially when the heat sensor is misaligned. Put the thermostat on the correct setting.
3. Blocked Filters
Look through your filters. If you can see through them, they are not blocked. If you can’t, they are.
Have spare filters on hand. Swap out old ones with new ones. Some filters clog more often than others, so research different filters and buy the longest lasting ones.
Pet hair often gets trapped in filters. Clean the area around your unit often. Put the unit in a place where your pet cannot go near it.
4. Weak Airflow
Blocked filters, leaks, and loose seals can cause weak airflow. Inspect your cabinet on a regular basis.
A duct needs at least two feet of open space to circulate air inside a house. Move plants and furniture out of the way. Put your unit in a place where you can feel air flowing in.
5. Unit Vibrating
Even if your system works fine, parts may vibrate. Place your ducts in sturdy walls. Check them often, especially after extreme weather.
Extreme weather can warp the wood in your walls and window frames. Reinforce your system with weather seals. They protect against air flows.
