Spring maintenance focuses on preparing cooling systems for summer operation while addressing winter damage and optimizing equipment that has been dormant during heating season.
HVAC System Spring Preparation
Air Conditioning System Startup
Begin air conditioning preparation in early spring before the first hot weather. Remove winter covers from outdoor units and clear accumulated debris including leaves, dirt, and vegetation. Inspect refrigerant lines for damage from winter weather or animals, looking for signs of refrigerant leaks including oil stains or ice formation.
Filter Replacement and Airflow Optimization
Install fresh filters throughout the HVAC system, using the highest efficiency filters compatible with your equipment. Clean supply and return vents throughout the home, removing dust and debris that accumulated during winter heating season. Ensure furniture and household items haven't blocked airflow to vents during winter rearrangements.
Outdoor Unit Cleaning and Inspection
Clean outdoor condenser coils using a garden hose and appropriate coil cleaning solutions. Spray from inside the unit outward to avoid pushing debris deeper into coil fins. Straighten bent coil fins using a fin comb, as bent fins restrict airflow and reduce efficiency. Check electrical connections for corrosion or loose wires that could cause performance problems or safety hazards.
System Performance Testing
Test air conditioning systems during mild weather to identify problems before peak demand periods. Check that thermostats control systems properly and that temperature differentials across indoor coils indicate proper refrigerant levels. Listen for unusual noises that might indicate bearing wear, loose components, or other developing problems.
Water Heating System Spring Maintenance
Tank Water Heater Inspection
Inspect water heater tanks for signs of corrosion, leaks, or mineral buildup. Flush 2-3 gallons of water from tank drains to remove sediment that accumulated during winter. Check temperature and pressure relief valves for proper operation and replace anode rods if they show significant corrosion.
Tankless System Maintenance
Schedule professional descaling for tankless water heaters if not performed within the past year. Clean inlet water filters and inspect venting systems for obstructions or damage. Test safety systems including gas shut-offs and thermal protection devices.
Distribution System Optimization
Insulate hot water pipes that may have lost insulation during winter maintenance or repairs. Repair leaky faucets and fixtures that waste hot water and energy. Consider installing low-flow showerheads and faucet aerators if not already present.
Building Envelope Spring Assessment
Air Sealing Inspection and Repair
Inspect caulking and weatherstripping throughout the home for winter damage from thermal cycling and moisture. Pay particular attention to areas around windows, doors, and exterior penetrations where seasonal movement can create gaps.
Insulation Assessment
Check accessible insulation areas including attics and basements for settling, moisture damage, or animal intrusion that may have occurred during winter. Look for compressed insulation that has lost R-value effectiveness.
Ventilation System Preparation
Clean bathroom and kitchen exhaust fans that may have accumulated dust and debris during winter operation. Test operation and airflow to ensure proper moisture removal during humid summer months.
