How To Prep Your AC For Summer
The last thing you want is for your air conditioner to break during a summer heat wave. When the temperature starts rising in Chicagoland, you want your cooling system to be reliable.
This guide explains how to prepare your AC for summer. It includes what you can do yourself and when to call the experts.
7 Summer AC Maintenance Tips
Check and Replace Your Air Filter
A new air filter is one of the easiest and most effective ways to keep your AC running smoothly. Clogged filters restrict airflow, cause your system to work harder, and can affect your indoor air quality. Check your air filter every month during peak use, and replace it every one to three months.
Clean Your Outdoor Unit
Since your condenser lives outside, it can be affected by things like grass, dirt, leaves, and other debris. Ensure there’s at least two feet of unobstructed space around the unit. Gently rinse off the coils and fins with a garden hose to improve airflow.
Inspect and Clean Vents and Ducts
Make sure all the vents in your home are open and not being blocked by furniture or rugs. If the vents are dirty, clean the covers to maximize airflow. If your vents have excessive buildup, it might be time to schedule a professional cleaning.
Double Check Your Thermostat
Set your thermostat to cooling mode and double-check that your system turns on. A faulty thermostat can lead to cooling issues or make you think your system needs repair when it doesn’t.
Test Your Air Conditioner
Once your thermostat is set, let your AC run and pay attention to any strange noises or uneven cooling. Also, see how long it takes for your home to reach the desired temperature; this can help you assess any issues.
Look For Red Flags
Keep an eye out for warning signs that your air conditioner might be malfunctioning. If you notice warm air blowing from the vents, weak airflow, or a sudden increase in your utility bill, these could be signs that your system is struggling.
Schedule Professional Maintenance
Preventive maintenance helps ensure your cooling system works correctly after a long season of inactivity. A professional HVAC tune-up identifies and fixes minor issues before they become larger repairs.
