Does your air conditioner have the correct airflow and refrigerant charge?
Unless you are a certified HVAC professional, you probably don’t even know what the correct airflow and refrigerant charge is, much less how to check it and make adjustments. But having the correct amount of refrigerant and the correct amount of air flowing through your A/C system is vital if you want your air conditioner to cool efficiently and last a long time.
This term refers to the amount of air that passes through your A/C system each minute. The flow of air is measured in CFM, or cubic feet per minute. For each ton of A/C capacity, your A/C blower should provide about 400 CFM of air. A two-ton system, for example, needs 800 CFM of airflow. If the airflow is too low, it won’t be able to transfer all of the cooling output into your home, and your electric bills will be higher. If airflow is too high, your A/C won’t do a good job of removing moisture from the air, and you will be left with humidity problems.
“Refrigerant charge” refers to the amount of refrigerant within your A/C. Every air conditioner is designed to run on a specific refrigerant charge, and having too much or too little refrigerant will cause it to operate at less than its stated energy efficiency and capacity. Incorrect refrigerant levels can also damage certain parts of the A/C, such as the compressor, leading to costly repairs or a shorter system life.
That is why you should schedule annual maintenance on your A/C system, and make sure that maintenance includes measuring airflow and refrigerant charge. An annual check-up can identify small problems, like leaks, before they turn into larger problems. It can also save you money on your electrical bills, while extending the life of the system and reducing lifetime costs.
