5 Signs Your AC Needs a Tune-Up

Your AC is Louder than Normal
After a long winter of no use, your AC might need a pick me up! An unusually loud AC could mean a number of things, but the most common issues are typically related to loose screws, motor malfunctions, debris build-up, and bent blades.
Screws hold your system in place, so if you're noticing an increase in noise level, it could be a sign a few of those have fallen loose.
Unlike your car, your AC is made up of multiple motors. Different noises often indicate where the malfunctioned motor is. For example, a grinding noise could relate to an issue with your fan motor.
Having debris caught in your AC unit can create some strange noises. Turn off your AC unit and clean in and around the area. Trim any surrounding hedges and remove any twigs or branches that may cause problems.
A bent blade can oftentimes be the culprit for a noisy AC unit. Look at the blades on your unit. Take note if any appear to be bent. Even the slightest bend can cause the blade to rub against the inside of the unit, causing the loud noise.
Uneven cooling temperatures throughout your home shouldn't go unnoticed. Ensure that if there are windows or doors in rooms with uneven temperatures that they are properly sealed. If you don't notice the temperature evenly distributing, it might be a good idea to contact a heating and cooling expert.
Your AC is Blowing Warm Air
The last thing you want is your AC to be blowing warm air into your already hot home. If you're experiencing warmer air, the first place to check out is your air filter. The air filter is one of the most important components of your air conditioning system. When you're dealing with a dirty air filter your airflow can be affected. When the air can't flow properly throughout your air conditioning system, it can make the air feel warmer.
Strange Smells Coming From Your AC
If you ever got home and turned your AC on only to be wafted with a horrible smell in the air, there could be several causes. Dirty condenser coils can build up grime and dust. When your AC fires up, it blows air over these coils, so if they are caked in dirt and bacteria, you'll be able to smell it.
Another issue could deal with your air filtration quality. If your air filters aren't protecting your home from outside air and bacteria, foul odors can fill your home.
Weak Outflow of Air
If you notice cool air isn't reaching its destination, it could be a sign that there is something going on with your air ducts. This could also have to do with your air filters, so if you've replaced these already, it's safe to assume that isn't the case here. If one of your air ducts is leaking, you are wasting precious air! And no, duct tape is not the answer here!
For maximum efficiency, annual tune-ups/maintenance is recommended.
