AC Maintenance Checklist

Can you imagine a hot Nashville summer without air conditioning? Your air conditioning system can be your very best friend on the warmest days. 

Be sure you take the time to perform basic maintenance regularly as well as invest in a professional checkup at least once a year. According to the US Department of Energy (DOE) , good maintenance can save you money and reduce your energy usage.

Here’s a comprehensive air conditioning maintenance checklist, courtesy of our professionals at True Blue Heating & Cooling, to help keep your system in excellent working order.

Check Air Circulation

Perhaps the most important thing to be sure you have around your air conditioner is plenty of space for good air circulation. Most air conditioners have a unit that sits outside your home. 

It’s a good idea to inspect this area to be sure leaves, sticks, and other yard debris are cleared every spring. However, once the summer in Nashville gets into full swing, don’t forget to mow and weed wack around your unit as well.

Change Filters

Being sure you regularly change your filters accomplishes the same goal of ensuring good air circulation. If you have a clogged filter, it can take your air conditioning system more effort to move the air throughout the unit, wearing down parts prematurely. Pay attention to the recommended life of your filters and change them on time.

Uses Your Senses

General awareness of how your air conditioning system should sound and look can be a simple thing for you to have. If you notice something doesn’t look quite right or your air conditioner is suddenly making unusual sounds or emitting strange odors, it can signal a need for air conditioning repair or maintenance. 

Check Coolant Levels

Although the first three items on the checklist are easy for just about any TN homeowner to do, the remainder of these items may take a bit more experience. If you are uncomfortable with any of these additional maintenance tasks, be sure to call in one of our professionals to help. 

The refrigerant or coolant must be at a specific level and pressure to keep your air conditioning system running efficiently. You’ll want to periodically check this level, and if your coolant is low, you’ll need to call in one of our professionals to refill your system. In addition, leaking coolant can be a significant problem for the environment, so address any noticeable leaks immediately.


Look for Ice Buildup

If you notice your air conditioning evaporator coil has ice building up on it, you probably have an air-circulation problem. Double check to be sure your filter and ductwork are clean. 

If you have a great deal of ice, you may need to shut off your system, defrost all of it, ensure air circulation is fine, and then turn it back on. If the problem continues, it’s a good idea to call one of our professionals to conduct an inspection.

Inspect Connections

Be sure all the electrical connections as well as ductwork and other tubing within the system look tight and secure. Again, this may take experience to understand what a solid system should look like, and you may want to rely on a professional inspection once a year. 

Most heating, ventilation, and air conditioning HVAC companies will provide a comprehensive service of cleaning and inspection for a reasonable fee. Relying on certified, trained technicians can be an excellent investment in your air conditioning system. Call our True Blue Heating & Cooling team with any questions you may have.

Check Thermostat

A thermostat is a bit of a tangential part of an air conditioning system, but it’s an important one. If your thermostat is not working properly, it will not be sending the correct information to your air conditioner. 

As a result, your system can’t work properly. In addition, if a broken thermostat causes your system to cycle on and off too frequently, it can cause longer-term damage to your entire air conditioning system.

We have used True Blue twice now. Both times we were happy with our experience. This time, although an unfortunate diagnosis for an entire new unit, Matt was fantastic! He was helpful, informative, very upfront and made the process seamless and quick to get handled. Very friendly and professional. We will be using them for all future needs!

True Blue Heating and Cooling went above and beyond to resolve our HVAC issue. We were experiencing an A061_F Blower Fault error, where the motor couldn’t run. Matt quickly diagnosed the problem on the first visit and determined that we needed a new control panel board and blower motor. By the second day, both were installed, and everything was running perfectly!Matt was exceptional—his communication was clear and professional every step of the way. Brandy was also kind and understanding, following up with me after I missed her call.The team’s efficiency, expertise, and excellent customer care make them stand out. I highly recommend True Blue Heating and Cooling!

Very pleased with the service provided by Randy! He was on site less than 24 hours after putting in the request, carefully went through our system and made recommendations on repairs or additions, and when we decided to move forward, he scheduled for next day and had everything installed and ready to go in about an hour. We were not happy with our previous HVAC company and wanted to try someone different. We’ll be sticking with True Blue moving forward!

Casey and Matt at TrueBlue were great! We were on the fence of getting a completely new unit because of the cost. After we heard about a Bosch unit that was extremely efficiently AND QUIET! we choose the change our 17 year old unit that was on its last leg. They even rip out and exchanged the ducting to new! It was fast service. Within a week they were here and completed the job in one day (new duct and all). I highly recommend TrueBlue if you need a new HVAC unit.

I recently had some concerns about my AC unit being unusually loud, and after my builders assured me everything was fine, I decided to get a second opinion. Casey was incredibly helpful. He kindly took the time to thoroughly inspect my unit and confirmed that everything was indeed in good working order. His professionalism and attention to detail provided me with the peace of mind I needed. If you're looking for reliable service, I highly recommend checking these guys out!
