Change the Filter Regularly

Maintaining a central air conditioning unit is all about maintaining airflow. That is why it is important to regularly change the air filter on the system.

Filter packages usually state a recommended schedule for replacement (i.e. every 90 days or so) but it really depends more on how much the unit is running and how dirty the air is.

During hot months, it may be beneficial to change the air filter more frequently. The process is often as simple as sliding the old filter out and sliding in the new one.

According to air conditioner manufacturers,

…regular cleaning/changing of your filter will ensure the best filtration, increase the life of your machine, and give you peace of mind that you’re breathing easier.

Do Not Close Any Registers Completely

With a two-story house the upper level is often warmer than the lower level even with the central air running. This is the case with our home, and knowing that hot air rises and cool air falls I figured I could easily balance the air temperature by adjusting the register (air vent) openings.

The mistake:

It is true that closing some registers on the cooler lower level forces more air out of the registers upstairs. The cooler air then works its way downstairs and the air temperature becomes more even throughout the house. However, by doing this the air conditioning unit may completely shut off!

In fact, when level registers are totally closed, the coils in the unit froze and the A/C quit functioning. Luckily, by shutting off the entire cooling system and giving the coils time to thaw, the A/C was up and running again within a few hours.

The lesson:

Do not completely close registers. To balance the air temperature, registers can be slightly closed, but do not close them completely. Additionally, make sure supply vents are not blocked.
