How to Prevent Your AC from Breaking Down in the Summer

The summer months are notorious for being hot and humid, but this doesn’t stop people from using their air conditioners to stay cool. However, if you want to avoid an AC breakdown in the summer, it’s important to take certain precautions. Your AC should be in good working condition to avoid AC repair and AC replacements, especially during the hottest months of the year.

Here are some tips you should consider.

Stop Overworking It

Preventing an AC breakdown in the summer starts by not overworking it. Keep it running on a regular schedule to prevent your AC from breaking down. This means that you should be mindful when your unit is on, and avoid leaving it on unnecessarily, like leaving it running while you are out of town. If you notice that your air conditioning isn’t as cold as usual, you should start by increasing the temperature setting and then try restarting your unit.

Turn Off the Lights

If your AC is running, you should also turn off all lights that you’re not using in your home. This is because every light bulb generates heat, which can add to the heat buildup inside your home. This means that, while if you’re not using them, it’s always smart to turn off the lights during the summer months.

Stop Using the Fan so Often

Another way to avoid an AC breakdown in the summer is by not using the unit’s fan so often. If your AC is too cold, it can either be because you are overworking it or that you are running your indoor unit during the winter months on high temperatures. If this proves to be true, then shutting down the unit for a few days should kick start the cooling system again.

Clean and Change Filters Regularly

If your AC has a filter, clean and change it regularly. Filters are especially important to keep clean during the summer months because they protect your air conditioner. Without a clean filter, you might be forced to replace your unit sooner than you would have to otherwise. Dirty filters also hinder the airflow of your AC, which can lead to overheating.

Clean Your Coils Regularly

The coils of your AC should also be kept clean after periods of high humidity. You should try to wipe them down periodically with a rag that has been soaked in rubbing alcohol. This will help prevent the growth of mold and mildew, which can cause an AC breakdown in the summer months.

Remove Furniture and Add Fans

Having a lot of furniture can block the air flow in your home. Remove unnecessary furniture, especially if it is placed in front of a vent, and place fans strategically throughout your home. If some furniture cannot be moved but it is in a central spot in your home, use a fan nearby to keep the air moving. Consider a personal sized fan to keep yourself cool as you move throughout your home. If you’re cool while you sit inside, you won’t feel the need to overwork your unit.


There are a number of steps that can be taken in order to prevent an AC breakdown in the summer months, but if your unit has already broken down, it might be time for a replacement.
