Totally Cool has been providing a broad range of air conditioning services to the Austin area for more than 30 years. During summer, our service calls often deal with air conditioning systems that are operating but creating indoor environments that are unevenly cool. Here is a list of the top five causes of AC airflow problems.
1. Dirty Air Filters and Return Vents
Your system has at least one air filter and perhaps more that are designed to prevent particulates from entering the system. As a rule of thumb, such filters should be replaced at least every several months to maintain optimal airflow. Return vents should be kept open and dusted once a month or so.
2. Closed Return Vents or Not Enough Vents
Many people incorrectly presume that closing vents in unused rooms will save on energy costs but doing so actually creates a pressure problem that reduces airflow and can increase costs. A system with an inadequate number of vents can experience similar problems.
3. Duct Leakage
Your air ducts are crucial to distributing conditioned air throughout your home efficiently. Leaks can develop over time, which undermines this efficiency. It is a good idea to have your ducts cleaned at least every several years, and they can be inspected during this task as well.
4. Refrigerant Leaks
Refrigerant leaks that can occur over time are among the best arguments supporting seasonal maintenance visits. Such leaks can cause your AC to stop cooling altogether, but in many cases, the result is more uneven, and you will experience hot spots in some areas depending on how air moves through the home.
5. Undersized AC Unit
A common mistake made by do-it-yourselfers is to install an AC unit that is too small for the home. If you purchased an existing home, have the AC inspected for suitability to the environment.
In addition to air conditioning, Totally Cool in Austin specializes in heating services, and we offer preventative service agreements. Contact us at your earliest convenience with any questions or to schedule an inspection of your AC system.
