Did you know that American demand for AC hit an all-time high of 15.3 million units in 2018?

It’s hot, you’re sweaty, and your A/C is on the fritz. You don’t want to think about it now, but you know you need to get your yearly HVAC tune up.

Not only is it important to stay cool in the summer, but skipping your yearly HVAC tune up can lead to bigger problems down the road.

But don’t worry. Keep reading to see when the best time is to get your yearly HVAC maintenance and HVAC check-up, what you can expect during the process, and how it will help keep you comfortable all year long.

Why You Need a Yearly Tune Up

Your A/C unit is made up of a lot of moving parts, and over time those parts can start to wear down. A professional HVAC technician will examine all of the major components of your unit, and identify any potential issues. By catching problems early, you can avoid a costly repair bill down the road.

In addition to examining the physical components of your unit, a tune up is also an opportunity to clean out all of the dust and debris that can accumulate over time. This build-up can cause your unit to work harder than it needs to, leading to higher energy bills and shortened lifespan for your A/C.

What to Expect During Your Tune Up

Ready to book an HVAC tune up? When you schedule a tune up for your A/C, a professional technician will come to your home and examine the following:

Air filters

Air filters need to be replaced regularly to be effective. Depending on the type of filter and the level of pollution in your area, they should be replaced every 1-3 months. If it’s been a while since you’ve changed your air filter, don’t worry – the technician will do it for you. Just be sure to let them know how long it’s been since the last time it was replaced.

Refrigerant levels

Most people know that their A/C unit needs electricity to run, but few realize that it also depends on a specific amount of refrigerant. This substance helps to cool the air as it circulates through the unit, and if the levels are too low, the A/C will be less effective.

In some cases, the unit may even overheat and shut down. That’s why it’s important to have a technician test the refrigerant levels regularly.


The coils in your A/C unit can get dirty over time, which reduces their efficiency. The technician will clean the coils and make sure they’re in good working condition during an HVAC repair.


The belts in your A/C unit can get worn down with use, causing them to slip or break. The technician will inspect the belts and replace them if necessary.

Ready for an HVAC Tune Up?

The best time to get your yearly HVAC tune up is before the hottest months of summer. A tune-up will help ensure that your air conditioning unit is running at its best and keeping you cool all summer long.
