Triple-digit temperatures across the Treasure Valley has some heating and cooling companies working overtime.

KTVB spoke with Diamond Heating and Cooling in Garden City about what it takes to keep your air conditioner functioning properly this summer.

The company says it's all about preventive maintenance.

We also asked about the what causes the most air conditioning problems.

“Lack of maintenance. It really is. When we can get in front of these problems and clean these systems up and get them ready to withstand the heat it makes a huge impact on its ability to perform in the heat, so that's the biggest problem we see. The other problem is dirty filters; which is also a maintenance item," Kimber Doolittle, Diamond Heating and Cooling Service Manager, said.

When it comes to how often you should change your filter, Doolittle told KTVB, it depends on the size of your home, the number of people in your household and if you have any pets; but it's usually recommended every one to two months.
