Summer Home Maintenance Tips for Mankato Homeowners

By Closer Look Home Inspectors | (507) 721-3820

Mankato summers bring heat, humidity, severe thunderstorms, and heavy rain, all of which stress your home's systems in different ways than winter. These maintenance tips help you protect your investment and stay comfortable from June through September.

Air Conditioning Maintenance

• Change filters monthly: Summer pollen and dust clog filters faster, reducing efficiency
• Keep condenser clear: Maintain 2 feet of clearance around the outdoor unit, trim vegetation, and clean debris from fins
• Check refrigerant lines: Insulation on copper lines should be intact, not crumbling or missing
• Monitor performance: If the system runs constantly without reaching set temperature, schedule service
• Clean condensate drain: A clogged drain causes water backup that can damage ceilings and walls

For comprehensive AC evaluation, see our AC maintenance guide.

Moisture and Humidity Control

Mankato's summer humidity regularly exceeds 80%, creating ideal conditions for mold growth:

• Run a dehumidifier in the basement, targeting 50% relative humidity or below
• Ensure bathroom exhaust fans vent to the exterior, not the attic
• Check for condensation on basement walls and windows
• Address any musty smells promptly, they indicate moisture or mold problems

Storm Preparedness

Southern Minnesota experiences severe thunderstorms with damaging winds, hail, and occasional tornadoes:

• Trim trees: Remove dead branches overhanging the roof and near power lines
• Secure loose items: Anchor or store outdoor furniture, trampolines, and decorations
• Check sump pump: Heavy rains can overwhelm drainage systems, verify pump function and consider a battery backup
• Review insurance: Confirm coverage for wind, hail, and water damage

Exterior Maintenance

• Deck maintenance: Clean, stain, or seal your deck. Check for loose boards and secure railings. See our deck inspection service.
• Foundation drainage: Verify grading still directs water away from the home after spring rains
• Window and door seals: Check caulk and weatherstripping for deterioration
• Garage door: Test auto-reverse safety feature monthly, lubricate moving parts

Plumbing Checks

• Inspect outdoor faucets for drips or leaks
• Check washing machine hoses for bulging, cracking, or weeping
• Test water heater pressure relief valve
• Monitor water bill for unexplained increases indicating hidden leaks

Pest Prevention

• Seal gaps around utility penetrations, windows, and door frames
• Keep vegetation trimmed 12 inches from siding and foundation
• Store firewood at least 20 feet from the home and elevated off ground
• Check window screens for tears and repair promptly
