1. Start with a Filter Check
Your AC filter works overtime during Maryland’s allergy season — catching pollen, dust, and pet dander before it clogs your airflow. A dirty filter makes your system work harder, wasting energy and reducing performance. If it’s been more than 60 days, swap it out now. If you have pets or allergies, aim for every 30 days during peak season.
2. Clear Out the Outdoor Unit
Head outside and take a look at your condenser unit. Winter can leave behind leaves, sticks, and dirt that block airflow. Trim back any bushes or weeds within two feet, and gently spray the coils with a garden hose to remove grime. Just be sure the power is off before you do anything hands-on.
3. Check the Vents Inside
Blocked or closed vents can throw off your AC’s balance. Make sure all your supply and return vents are open and unobstructed. Furniture or rugs blocking vents can lead to poor airflow, uneven cooling, and higher utility costs. This is especially important in Baltimore row homes, where airflow can already be tricky.
4. Test Your Thermostat
It might seem obvious, but a quick thermostat test goes a long way. Set it to cooling mode and drop the temp a few degrees. Make sure your system kicks on promptly. If there’s a delay, strange noise, or no response, it could point to an issue you’ll want to fix now — not mid-July.
5. Inspect for Leaks and Odors
When your system first runs in spring, watch for signs of leaks or musty smells. Baltimore’s damp basements and crawl spaces are a breeding ground for mold, and clogged drains can lead to water damage or mildew smells in your ductwork. If anything seems off, call in the pros.
