Central air conditioning systems work by sucking in air from inside a home, absorbing heat from the air, and then dumping the cooled air back into the home. Having sufficient air flow inside the air conditioning system is important because it determines how much air is available for cooling at a given time and hence the rate at which cooled air is introduced into a home.
There is also the fact that manufacturers design air conditioning systems with a given airflow rate in mind. Therefore, when the airflow rate is below a certain point, it can lead to complications such as coil icing that may then reduce the efficiency of the air conditioning process. The following are some of the things that you can do to avoid restricted airflow problems.
Remove return air register obstructions
Air register returns form the entry point for any air that enters the air conditioning system for cooling. Unfortunately, these inlets sometimes get blocked by furniture and other huge items around the home, thereby limiting the amount of air that can be pulled into the air conditioning system. There are also times when dirt and debris accumulate on the grills of the registers. This then restricts the amount of air that the return air registers can allow to pass through at any given time.
If your air conditioning system’s cooling efficiency has dropped, check for any register obstructions. Remove any furniture that may be blocking the registers. And if the registers are dirty, use a bucket of water and a cloth to clean them.
Clean the system’s air filters
Any air that is pulled into the air conditioning system has to pass through the system’s air filters. This is necessary so as to not only improve the quality of air that gets dumped into a home, but also to reduce the rate at which the air conditioner’s parts get clogged with dirt and debris. With time, this usually causes the filters to get clogged. And since clogged filters limit the amount of air that can get into the air conditioning system, it usually leads to airflow-related air conditioning problems such as evaporator coil frosting.
To avoid air filter clogging, you will have to clean your system’s air filters regularly. Doing so with a wet cloth is usually enough to improve the performance of your system. And given the importance of the role that the filters play, making sure that you change them at least once every 3 months will go a long way towards ensuring that your system is effective in not only cooling your home, but also in purifying the air that you and your family inhale.
