It's HOT in McKinney TX. Get your 5 day forecast and check out the best way to get the most air conditioning capacity out of your AC unit this summer with these 3 tips.

Step 1. Change your filter frequently. This is a step that is mostly overlooked in the summer. Most of the time customers tell me their AC filter only needs to be changed every 90 days... this is just not the case. In fact most AC filters in residential homes are 1 inch thick and require a new filter to be installed every 30 days when it is very hot outside. Your air conditioning unit will cool down faster and use less electricity with a brand new filter.

Step 2. Clean your outside unit. The outside unit draws air across the coils from the vertical sides and blows it out the top. When it is running almost most of the day in the summer you can imagine how much air the machine will pass through those coils. It is recommended that you clean your coils outside at least once a year. This will increase your capacity(because you need more AC for your house when it is 105 degrees outside) and reduce your electricity bill.

Step 3. Get your freon checked by a licensed and insured AC contractor. This step is vital to prevent premature damage to the system when running low on freon. Getting your freon checked in the AC unit at home should be a yearly thing. This helps make sure your always at top capacity and efficiency even if you do not have a brand new AC system at home.
