Tips to Keep Your A/C Unit Maintained Year-Round

Tips to Keep Your A/C Unit Maintained Year-Round

Minnesota summers may be short, but when the heat hits, you want your air conditioning system to perform at its best. At MD’s Heating and Air Services, we’re a local, family-owned HVAC company dedicated to helping homeowners stay cool, comfortable, and energy-efficient through expert AC maintenance, professional repairs, and reliable installations.

With our state’s extreme seasonal swings, regular A/C care is especially important for performance and longevity. Below are simple yet essential tips to maintain your A/C unit and avoid unnecessary AC repair costs, along with how MD’s Heating and Air Services can help.

1. Change the Air Filter Regularly

One of the easiest ways to improve system efficiency is by changing the air filter every 1 to 2 months. A clean filter reduces allergens, improves airflow, and keeps your unit from working harder than it should.

Pro Tip: Don’t forget to check the filter size before purchasing a replacement. Using the wrong size can reduce filtration effectiveness and strain your system.

2. Check and Clear Vents

Blocked vents make it harder for your A/C to cool your home. Walk through each room and ensure that vents are free of furniture, curtains, rugs, or other obstructions. Good airflow helps maintain a consistent indoor temperature while reducing energy consumption.

3. Deep-Clean the Condenser Unit Annually

Your outdoor condenser unit collects dirt, leaves, and debris over time. Once a year, gently clean the unit with a hose (avoid using high pressure), and clear any buildup from the fins and coils.

If you’re uncomfortable doing this yourself, our team offers thorough system cleaning as part of our AC maintenance services.

4. Keep the Area Around the Outdoor Unit Clear

Proper airflow around the outdoor condenser is critical. Maintain at least 2 to 3 feet of clearance on all sides. Remove foliage, furniture, and tools that could restrict airflow or make the unit work harder.

This small step can significantly improve the efficiency of your Minnesota heating and air conditioning system.

5. Provide Shade Without Blocking Airflow

A/C units run more efficiently in cooler conditions. Planting shrubs or bushes that don’t shed leaves near the unit can offer valuable shade. Just make sure they’re planted far enough away to avoid clogging or airflow issues.

This is a natural and effective way to support your system's performance, especially during peak summer months.

6. Inspect Electrical Connections

Loose or damaged wiring can lead to performance issues—or worse, safety hazards. Carefully inspect your unit for frayed wires or loose connections. If you notice anything concerning, schedule professional AC repair immediately.

Our licensed technicians at MD’s Heating and Air Services can perform safe, thorough diagnostics to resolve issues before they escalate.

7. Cover the Unit in the Off-Season

When the cooling season ends, protect your A/C unit with a breathable cover. This helps keep out debris, ice, and moisture while allowing airflow that prevents condensation buildup.

Avoid plastic covers that trap moisture and lead to rust or mildew.
