Your Ultimate HVAC Maintenance Checklist for Spring

Your Ultimate HVAC Maintenance Checklist for Spring from ATN Mechanical Systems

It’s been a cold winter but as the weather is beginning to get a bit warmer, it’s time to start preparing your home and your HVAC system for the hot summer months that are just around the corner. One of the best things that you can do for your equipment is preventive seasonal HVAC maintenance in the spring to ensure your air conditioner runs at peak efficiency, just in time for the hot and humid summer weather! 

Proper maintenance of your home HVAC system will improve its efficiency, lower the energy bills, and prevent you from having to make high costing emergency repairs. After all, nobody wants to be stuck with an air conditioner that is not functioning properly in the middle of a super hot and humid summer day!

You can do several things at home to prepare your HVAC system for the upcoming heat and humidity; however, you should schedule annual service and maintenance appointments with a team of professionals to keep your home HVAC system running smoothly every month of the year.

Here is our Ultimate Spring HVAC Maintenance Checklist:

1. Remember to Replace Your Air Filters

It is one of the most commonly forgotten items on the HVAC checklist! Perhaps you can schedule filter changes on your smart device or phone. Set up a re-occurring quick reminder as over time your HVAC air filters become clogged with built-up dust, dirt, and debris.

If you forget to change the filters and this happens, your system has to work so much harder to keep the temperatures in your home at a comfortable level. A filter that is not replaced regularly can cause airflow issues, uses more energy, and even lead to severe damage to your system.

We would suggest to replace your air filters every three months. This will also help to decrease your energy costs! Furthermore, your equipment works more efficiently, but your indoor air quality will improve significantly. An ATN Mechanical Systems HVAC technician is more than happy to help you change your air filters during a maintenance or service appointment! Or we show you how to properly do this on your own so you can add this as part of your maintenance checklist.

2. Remove the Cover on Your AC Unit and Clean Around the Unit

With the summer months just around the corner, it is a good idea to take a look at your AC unit. As you prepare for the use of your air conditioner, you need to clean up the dirt and debris left behind from the winter months. Clear away any leaves from on top of your air conditioner’s top grill. Cut back any nearby bushes or shrubs in order to create two feet of clearance around your outdoor unit. We also suggest scheduling a maintenance appointment with a professional to have your air conditioner unit fully inspected for any potential damage that occurred over the winter. This will allow time to fix any necessary repairs before the heat and humidity of summer are here!

And – before you turn your AC unit on…Don’t forget to take the cover off your A/C unit! This simple step is essential since your system won’t work correctly with the cover on.

3. Check the Air Conditioner’s Refrigerant Lines

You may want to check the refrigerant levels according to your system. Too much or too little refrigerant will reduce the efficiency of your equipment. This can also cause an increase to your energy bill. Another item on the HVAC checklist is to check the refrigerant lines to be sure they are not worn, detached, or leaking. If you need assistance with these checkpoints, we are here to help!

4. Keep the AC Unit Level

Take a walk outside and make sure that the unit is properly levelled. Over time the concrete pad and stones under the unit can sink or tip to one side. This will put strain on the coolant lines and could cause the unit to have larger issues. To avoid unwanted damage to your air conditioner, make sure that this task is added to your spring HVAC checklist. In fact, we would suggest checking on this every couple of months!

5. Thermostat – Adjust It, Don’t Leave It

Make sure your cooling and heating systems are working correctly by setting the thermostat to cooling mode and run the air conditioner for 15 minutes when you first turn it on. If you don’t have a smart thermostat, you may want to consider having one installed this spring. The convenience and control of having a smart thermostat will save you time, money, and hassle! Give us a call to discuss which options would be best for your home.

6. Schedule your HVAC Maintenance Appointment

Early spring is the best time to schedule your annual HVAC maintenance appointment! Don’t wait until the warmer weather is here to have your air conditioner serviced, as you run the risk of being left without A/C in the middle of a hot and humid summer day. Without proper maintenance of your HVAC system, there is a greater chance it may need costly emergency repairs or even replacement. Avoid the hassle and wait times and contact us today to schedule your annual maintenance check.
