Spring HVAC Maintenance Checklist: Prepare Your System for Warmer Weather

As temperatures rise in Des Moines, it's time to shift your focus from heating to cooling. A well-maintained air conditioning system runs more efficiently, lasts longer, and keeps your family comfortable all summer long.

Why spring HVAC maintenance matters

Regular maintenance isn't just about comfort. It protects your investment and helps your system perform better when demand spikes.

• Prevent costly breakdowns during peak summer heat
• Lower energy bills by improving system efficiency
• Extend equipment lifespan by catching small issues early
• Maintain warranty coverage on your HVAC equipment
• Improve indoor air quality for your family's health

Your spring HVAC maintenance checklist

1. Replace or clean air filters

Dirty filters restrict airflow, making your AC work harder and less efficiently. Check filters monthly during cooling season and replace them every 1 to 3 months depending on usage and filter type.

2. Clean around the outdoor unit

Your outdoor condenser needs breathing room. Clear away leaves, grass clippings, and debris within at least 2 feet of the unit.

3. Inspect thermostat settings

If you use a programmable or smart thermostat like our Freedom Smart Thermostat, create a summer schedule that saves energy while you're away without sacrificing comfort when you're home.

4. Check indoor vents and registers

Make sure supply and return vents are open and unobstructed. Furniture, curtains, or rugs blocking vents force the system to work harder and can create hot spots in the home.

5. Test your system early

Don't wait for the first 90-degree day to discover your AC isn't working. Run the system in early spring, listen for unusual noises, and verify that cool air is reaching all vents.

Professional maintenance is the smart investment

Homeowner upkeep matters, but professional service is still the best way to protect long-term performance.

• Inspect and clean evaporator and condenser coils
• Check refrigerant levels and look for leaks
• Test electrical connections and tighten if needed
• Lubricate moving parts to reduce friction
• Measure airflow and temperature differential
• Inspect the condensate drain and clear if clogged
• Test safety controls and overall system performance

Common spring HVAC problems to watch for

• Weak airflow from vents
• Warm air instead of cool air
• Grinding, squealing, or banging noises
• Unusual odors when the system runs
