If you’re like most people, when you turn on the AC, you may expect it to cool down your home quickly and efficiently. But when your AC is not working properly, not only will you be uncomfortable, but you could also see a spike in your energy bill as your HVAC system struggles to keep you cool. 

Before the heat of summer hits, it is important to take some time to prepare your HVAC system so that it runs smoothly and efficiently throughout the entire summer season. 

Here are some tips on how to do just that:

1.     Schedule an Annual Maintenance Checkup

2.     Change Your Air Filter Regularly

3.     Keep Your Vents Clear

4.     Seal Any Leaks

5.     Insulate or Re-Insulate Your Home

6.     Use Ceiling Fans

7.     Keep Your AC Unit Clean

8.     Upgrade to a Programmable Thermostat 

Now, let’s go more in-depth.

1. Schedule an Annual Maintenance Checkup

This is the best way to ensure that your HVAC system is running properly and to prevent any issues from arising. A professional will be able to clean the unit, check for any potential problems, and make any necessary repairs. A professional can also provide you with guidance to help you sustain your own maintenance year long.

2. Change Your Air Filter Regularly

A dirty air filter can restrict airflow and cause your AC to work harder than it needs to. As a result, your energy bills will be higher, and your unit will have a shorter lifespan. Be sure to check your filter monthly and change it as needed.

3. Keep Your Vents Clear

Make sure that there is nothing blocking your vents, as this can restrict airflow and cause your AC to work harder than necessary. If you have furniture or other items blocking your vents, simply move them out of the way. If you notice a buildup of dust and debris, clean them regularly and consider replacing vents in disrepair.

4. Seal Any Leaks

If there are any leaks in your ductwork, this can cause cool air to escape and warm air to enter. This will make your AC work harder and cause your energy bills to increase. Be sure to have any leaks professionally sealed so that your AC can run efficiently. If you’re unable to do this or you aren’t sure how to check, then contact an HVAC professional like us who can help!

5. Insulate or Re-Insulate Your Home

Proper insulation in your home will help to keep the cool air in and the warm air out. This will reduce the amount of work your AC has to do, which will save you money on your energy bills. If you’re not sure if your home is properly insulated, then contact an insulation specialist to assess your home and make recommendations.

6. Use Ceiling Fans

Ceiling fans can help to circulate the air in your home, which can make you feel cooler without having to lower the temperature on your AC unit. Be sure to use ceiling fans in conjunction with your AC unit rather than as a replacement, as fans alone will not be enough to cool your home during the hottest days of summer.

7. Keep Your AC Unit Clean

If your AC unit is full of dirt and debris, it won’t be able to work as efficiently. Be sure to clean your unit regularly, especially before the start of summer. You can hire a professional to do this for you, or you can rinse it off yourself.

8. Upgrade to a Programmable Thermostat

If you don’t already have one, consider upgrading to a programmable thermostat. This will allow you to set your AC to run only when you need it, which can save you money on your energy bills. You can also set it to a higher temperature when you’re away from home so that your AC doesn’t have to work as hard to cool an empty house.


With just a tiny bit of preparation and consistent checks, you can ensure your HVAC system will make it through the summer heat unscathed. And by following the tips we’ve outlined in this article, you can keep your home cool and comfortable all season long and save money in the long run.
