Is Your AC System Ready for Summer? The One Checklist Every Homeowner Needs

Max Williams • April 29, 2025

As the temperatures begin to rise, we all rely on our air conditioning systems to keep us cool and comfortable. However, before you crank up the AC this summer, it’s important to ensure your system is in top shape to handle the heat. At Rizzo HVAC, we understand how frustrating it can be when your air conditioning fails at the worst possible time, which is why we’ve created this pre-summer checklist to help you avoid a breakdown and stay cool all season long.


1. Change or Clean Your Air Filters


Air filters play a crucial role in maintaining your AC’s efficiency. Over time, filters can become clogged with dirt and debris, which restricts airflow and forces your system to work harder. This not only affects the cooling efficiency but can also lead to higher energy bills. Before summer hits, make sure to replace or clean your filters, depending on the type you have. For those with reusable filters, a quick rinse or vacuuming can do the trick.


2. Inspect and Clean the Coils


Your AC system has two essential coils: the evaporator and condenser coils. Both are vital for heat exchange, but over time, dirt can accumulate on these coils and affect their ability to cool effectively. The evaporator coil, located inside the air handler, can get dirty faster, especially if your filters are clogged. The condenser coil, located outside, is exposed to the elements and can collect debris, such as leaves and dirt. It’s a good idea to have the coils cleaned and inspected by a professional to ensure optimal performance.


3. Check the Refrigerant Levels


Low refrigerant levels can lead to poor cooling performance and even cause your air conditioner to freeze up. If you notice that your AC isn’t cooling as effectively as it used to, it may be time to check the refrigerant levels. This is not a task you should attempt on your own, as handling refrigerant requires specialized knowledge and tools. Calling the best AC repair & install company, like Rizzo HVAC, for an inspection and refrigerant refill is the safest and most effective solution.


4. Inspect the Ductwork for Leaks


Leaky ducts are one of the most common causes of inefficient cooling. Air can escape through gaps in the ducts, reducing your system’s efficiency and making your home less comfortable. Before summer, inspect your ductwork for any visible cracks, holes, or disconnected sections. If you find any issues, it’s best to call a professional to seal the leaks and restore your system’s efficiency.


5. Clear the Area Around Your Outdoor Unit


Your outdoor condenser unit needs ample space to operate efficiently. Over time, debris like leaves, twigs, and dirt can accumulate around the unit, obstructing airflow and reducing its cooling efficiency. Make sure to clear at least two feet of space around the unit and remove any obstructions. This will help your AC unit run smoothly and avoid unnecessary wear and tear.


6. Test Your Thermostat


Your thermostat controls the temperature of your home and communicates with your AC system. If your thermostat isn’t working correctly, your system may not cool your home to the desired temperature, or it could cause your AC to cycle on and off frequently, leading to inefficiency. Test your thermostat to ensure it’s calibrated correctly. If you have an older model, consider upgrading to a smart thermostat that can help you control the temperature remotely and save energy.
