Don’t forget to change your filters!

We have had numerous calls about AC & Heat Pumps not being able to keep up with the hot days. Inside temps of over 80 degrees!

The simple fix, changing the filter. This allows for better air flow and helps with the efficiency of your unit.

Doesn’t matter if it’s an AC unit, heat pump or a window unit, clean filters will help you stay cool!

This week is only going to get hotter!
With temperatures well into the 30’s your system will be working hard to keep up.

To help out, keep your curtains and blinds closed, and if you can, avoid cooking in the house. This is great BBQ weather!

If you run into any problems with your AC or heat pump, give us a call!
