TERRE HAUTE, Ind. (WTWO/WAWV) — With some of the hottest temperatures of the season settling into the city within the next few days, a local plumbing heating and cooling business gives tips on how to not overwhelm your cooling units.

“I would tell any homeowner out there, the most important thing is a clean air filter, one hundred percent,” said Scott Pickerill, HVAC Project Manager for B&S Plumbing Heating and Cooling.

Pickerill noted that even typical summer activities like mowing the grass or gardening can play a role in how well your cooling system works as debris can impact the effectiveness of AC filters when things get too hot to handle. 

“This time of year, after all the mowing grass and stuff like that blowing into the outdoor units, they’re usually dirty. It’s a great idea just to go out there with the garden hose, try to hose them down vertically, straight through the coils, just keep them clean.” 

While having clean filters will help to make sure an AC unit is running efficiently, it may just not be equipped to handle the extreme heat. Pickerill warns homeowners to not set their expectations too high.

“I think a lot of people, when the temperatures get this hot, they want their air conditioning to do things that it’s not really capable of. When it’s 100 outside, I mean, there’s no point cranking your thermostat down to 65, it’s not gonna do it. I try to tell everyone the basic rule of thumb, it’s 25 degrees. So if it’s 95 outside, you’re doing good if you keep your house at 70.”

For those that may not have access to AC, multiple churches, businesses, and other organizations in the area are operating as cooling centers for the community throughout the heatwave.
