PSA for all of the people with AC!!! Have you turned it on yet? Tomorrow might be the day, it’s gonna be a fairly hot one for the Southeast. A couple of things to remember!

- AC needs proper airflow. Your system will have a filter(s). Make sure to clean them if they’re washable, or replace them if its been more than 6 months!

- Set backs. Try to keep your thermostat set backs to a modest amount when the system is under heavy load. We recommend no more than 4°. For example, if it’s 90° out and you like 72° inside, we don’t recommend setting the stat past 76° when you leave so that the system doesn’t have to have to work so hard to catch back up. These big recoveries aren’t as cost effective as some may think.

- Condensing units. The big noisy box outside!! Be sure to check the outdoor unit for any over growth or impingement on the coil, lineset and fan blades. If found carefully remove!

- Maintenance. AC systems should have preventative maintenance performed at a min of every other year. Its the best way to keep your system performing efficiently and minimize the chance of issues in peak season.

- Lastly, if it does break down, shut it off for an hour, check the filter and give it one more try. If that doesn’t work, call us, or whomever you have that takes care of your equipment and check for availablity!!!

Hope any of this was helpful!! Keep cool folks!!
