As the last of the winter chill thaws and gives way to the warmth of spring here in the Ozarks, it’s the perfect time to give your HVAC system the TLC it deserves. 

After months of working hard to keep you cozy, a little maintenance can go a long way in ensuring efficiency, longevity, and readiness for the warmer months ahead. 

Obviously, the summers here in the greater Springfield area are kind of the ‘main event’ of the year. They’re hot, humid, and did we mention hot? And humid? Our air conditioners tend to get a serious workout. 

And that leads us to this—the final ‘checklist’ of stuff you need to do before you kick that AC into overdrive for those Missouri summer temperatures. 

This list will help you to ensure your system runs smoothly and efficiently:

1. Change Your Filters

A fundamental yet often overlooked task, changing your HVAC filters is crucial for maintaining air quality and system efficiency.

Why is this important? 

Well, over the winter, filters can become clogged with dust, pet dander, and other particulates, which can strain your system. 

A fresh filter not only improves airflow but also reduces energy consumption, potentially lowering your utility bills.

2. Clean Your Vents and Registers

Dust and debris can accumulate on vents and registers, obstructing airflow and forcing your system to work harder. 

Gently vacuum the covers, and if possible, remove them to clean the inside with a damp cloth. 

This simple step ensures unimpeded air circulation, enhancing comfort and system efficiency.

You may also need to look into cleaning your air ducts. Here’s a guide to help you know if it may be time to perform this step. 

3. Test Your Air Conditioning

Before the thermometer rises, give your air conditioning unit a test run. 

Listen for unusual noises and monitor how quickly it begins to cool your space. 

Here’s a concise bullet point list for what to look or listen for when testing an air conditioner:

  • Unusual Noises: Listen for any strange sounds like banging, clicking, or whistling, which could indicate mechanical issues.
  • Cooling Time: Note how long it takes for the AC to start cooling the room. Longer than usual cooling times may suggest a problem.
  • Air Flow: Check if the air coming out of the vents is flowing freely and strongly. Weak airflow could point to blockages or motor issues.
  • Thermostat Accuracy: Ensure the temperature reading on the thermostat matches the actual feel of the room. Inaccuracies could mean thermostat or sensor problems.
  • Unpleasant Odors: Be alert to any strange smells that emerge when the AC is running. Musty odors could indicate mold, while a burning smell may signal electrical issues.
  • Humidity Levels: The AC should reduce humidity levels within your space. High humidity can suggest the system is not working efficiently.
  • Continuous Operation: Notice if the AC runs continuously without cycling off, which could indicate it’s struggling to cool your home efficiently.
  • Leaks or Moisture: Check around the AC unit for any signs of leaks or excessive moisture, as this could indicate a refrigerant leak or drainage problems.

Identifying and addressing any issues early can save you from sweltering through unexpected breakdowns during the summer’s peak heat.

4. Inspect Your Thermostat

Is your thermostat accurately reading the temperature? Does it respond correctly to adjustments? 

Ensuring your thermostat is in good working order is key to efficient HVAC operation. 

Consider upgrading to a smart thermostat for greater control and potential energy savings.

5. Schedule Professional Maintenance

While DIY maintenance is important, having your HVAC system professionally serviced can uncover deeper issues and ensure it’s in top shape. 

An HVAC technician can clean components you can’t easily access, check refrigerant levels, and make any necessary repairs.

6. Clear the Area Around Outdoor Units

Remove any leaves, branches, or debris that have accumulated around your outdoor AC unit. 

And if you covered your unit before wintertime, now is the time to remove the cover. 

A clear area ensures adequate airflow and prevents overheating. Additionally, inspect the insulation on refrigerant lines leading into your house and replace it if damaged.

7. Consider System Upgrades or Replacements

End of winter is a great time to assess the overall health of your HVAC system. 

If your system is old, inefficient, or requires frequent repairs, investing in a newer, energy-efficient model could be more cost-effective in the long run.


This checklist can help extend the life of your HVAC system, improve its efficiency, and ensure your comfort as seasons change from winter, to spring, to summer. 

A little attention now can prevent big problems later, so don’t delay your end-of-winter HVAC maintenance. 

Get ready to welcome the warmth of spring with open arms and a well-tuned HVAC system!
