When the temperature starts to climb, we rely on our air conditioners to create a haven from the heat.
But the hotter it is, the harder our air conditioners have to work, which means there's also a better chance something can go wrong.
There are things you can do to keep your unit in proper working order before you start to feel the heat.
Air conditioning experts say the most common problems they find are plugged filters, dirty condensing coils, and low freon levels.
The main thing homeowners can do: make sure the unit is clean and the filter is replaced regularly.
A hose is an easy cleaning tool.
Also keep the bushes and shrubs cut back at least two feet from the air conditioner so it has proper air flow.
Most people don't know they have a problem until the unit stops working, but there are other indicators.
HVAC technician Adam Sellers says, "Some of the symptoms that you can realize yourself is the unit is running all the time and never shutting off, or your unit can freeze up downstairs and you'll have water all over the place downstairs or ice on the lines going from the inside to the outside."
Experts say if you notice your unit isn't working correctly, shut it off.
The longer it runs, the more dad make it much worse.
