Summer in our region means hot days, sticky nights, and plenty of time spent indoors relying on your air conditioner. But here’s the big question: will your AC make it through the season without a hitch? The last thing you want is for your system to fail in the middle of a heatwave.
The good news is that you can take steps right now to make sure your cooling system is ready to perform. Here’s a helpful checklist to guide you in preparing your AC for a worry-free summer.
Start With the Air Filter
Your air filter is small but mighty. A clogged or dirty filter restricts airflow, forces your AC to work harder, and can even cause breakdowns if ignored for too long. During summer’s peak use, filters should be checked monthly and replaced every one to three months. A clean filter also improves your indoor air quality, making your home healthier as well as cooler.
Clear the Outdoor Unit
Your outdoor condenser unit needs space and airflow to function properly. If it’s surrounded by tall grass, shrubs, or debris, your AC will struggle to release heat effectively. Take a few minutes to clear at least two feet of space around the unit and gently rinse the fins with a hose. This simple step can help your AC run more efficiently all summer.
Inspect the Thermostat
Your thermostat controls the comfort level of your home, so it needs to work correctly. Check that it responds quickly to adjustments and is reading the indoor temperature accurately. If you’re still relying on a manual thermostat, upgrading to a programmable or smart thermostat can help you save energy while ensuring steady comfort.
Look for Warning Signs
Your AC often shows signs of trouble before a breakdown happens. Be on the lookout for:
- Unusual noises like grinding, banging, or buzzing
- Uneven cooling or hot spots in certain rooms
- Weak airflow from vents
- Short cycling (constantly turning on and off)
- Spikes in your energy bill without explanation
If you notice any of these issues, it’s time to schedule a repair before the problem worsens.
Clean the Vents and Ductwork
Over time, dust and dirt can build up inside vents and ducts, reducing airflow and efficiency. Take a few minutes to vacuum your supply vents and make sure furniture isn’t blocking them. If your ducts haven’t been cleaned in years, professional cleaning may be worth considering—especially if you notice musty odors or uneven airflow.
Check Refrigerant Levels and Coils
Low refrigerant or dirty coils are two of the most common culprits behind inefficient cooling. While this part of the checklist requires professional service, it’s essential for keeping your system running properly. Annual AC tune-ups include coil cleaning and refrigerant checks, which can prevent costly breakdowns during summer’s hottest weeks.
Schedule Preventive Maintenance
Even if your AC seems to be running fine, preventive maintenance is one of the best ways to avoid unexpected issues. One of our licensed technicians will inspect, clean, and test your system to make sure it’s ready for heavy use. They can also catch small issues early—saving you from inconvenient breakdowns and expensive emergency repairs.
