HVAC Systems

Your heating, ventilation, and air conditioning system is one of the most expensive components in your home. Proper maintenance extends its lifespan by 5-10 years and reduces energy bills by 15-25%.

Cost of neglect: $5,000 - $15,000 for full system replacement

Maintenance Tasks

Replace air filtersEvery 90 days (monthly if you have pets)

Dirty filters force your system to work harder, increasing energy costs and causing premature wear.

Schedule professional tune-upTwice yearly (spring and fall)

Technicians catch refrigerant leaks, electrical issues, and efficiency problems before they become expensive repairs.

Clean vents and registersMonthly

Dust buildup restricts airflow and can trigger allergies.

Clear area around outdoor unitAs needed

Debris blocks airflow and reduces cooling efficiency.

Check thermostat batteriesAnnually

Dead batteries can cause the system to stop working at the worst time.

Pro Tips

  • Keep trees and shrubs at least 2 feet from outdoor units
  • Consider a programmable thermostat to save 10% on energy bills
  • Listen for unusual sounds - they often indicate problems
  • Change filters more often during peak usage seasons

Plumbing

Water damage is one of the most common and expensive home insurance claims. Regular plumbing maintenance prevents catastrophic leaks that can cost tens of thousands in repairs and mold remediation.

Cost of neglect: $7,000 - $30,000+ for major water damage

Maintenance Tasks

Check for leaks under sinksMonthly

Small leaks become big problems. Early detection saves thousands.

Flush water heaterAnnually

Sediment buildup reduces efficiency and shortens tank life.

Test water pressureEvery 6 months

High pressure (above 80 PSI) damages pipes and appliances.

Clean faucet aeratorsEvery 6 months

Mineral buildup reduces water flow and pressure.

Inspect washing machine hosesEvery 6 months

Rubber hoses fail suddenly and can flood your home.

Know your main shut-off locationDocument once

In an emergency, you need to stop water flow within seconds.

Pro Tips

  • Replace rubber washing machine hoses with steel-braided ones
  • Never pour grease down drains - it solidifies and causes clogs
  • Run water in unused drains monthly to prevent sewer gas
  • Consider installing water leak sensors near appliances

Electrical Systems

Electrical problems cause about 50,000 home fires annually. While major electrical work requires a licensed electrician, homeowners can perform basic inspections to catch warning signs early.

Cost of neglect: Fire risk, $3,000 - $10,000 for panel upgrades

Maintenance Tasks

Test GFCI outletsMonthly

These protect against electrical shock in wet areas like bathrooms and kitchens.

Check for warm outlets or switchesEvery 6 months

Heat indicates loose connections or overloaded circuits.

Inspect electrical panelAnnually

Look for signs of corrosion, burn marks, or unusual smells.

Test smoke and CO detectorsMonthly

Working detectors save lives. Replace batteries annually.

Replace smoke detector unitsEvery 10 years

Sensors degrade over time and become less effective.

Pro Tips

  • Never overload outlets with too many devices
  • Use surge protectors for expensive electronics
  • Flickering lights often indicate loose wiring - call an electrician
  • Keep space around your electrical panel clear

Exterior & Roof

Your home's exterior is its first line of defense against the elements. Regular maintenance prevents water intrusion, structural damage, and pest infestations that can cost tens of thousands to repair.

Cost of neglect: $5,000+ for foundation repair, $10,000+ for roof replacement

Maintenance Tasks

Clean gutters and downspoutsTwice yearly (spring and fall)

Clogged gutters cause foundation damage, basement flooding, and fascia rot.

Inspect roofTwice yearly and after storms

Missing or damaged shingles lead to leaks and structural damage.

Check exterior caulkingAnnually

Failed caulking lets water and pests into your home.

Inspect foundationAnnually

Cracks can indicate settling or water problems that worsen over time.

Trim trees near houseAs needed

Branches damage roofs and siding, and provide pest access.

Check gradingAnnually

Soil should slope away from foundation to prevent water intrusion.

Pro Tips

  • Install gutter guards to reduce cleaning frequency
  • Extend downspouts at least 4 feet from foundation
  • Use binoculars to inspect roof from ground level
  • Address small cracks before they become big problems

Safety & Security

Home safety systems protect your family from fires, carbon monoxide poisoning, and other hazards. Regular testing ensures they work when you need them most.

Cost of neglect: Priceless - safety systems save lives

Maintenance Tasks

Test smoke detectorsMonthly

Working smoke detectors double your chances of surviving a fire.

Test carbon monoxide detectorsMonthly

CO is odorless and deadly. Early warning is critical.

Replace detector batteriesAnnually or when they chirp

Dead batteries make detectors useless.

Check fire extinguisherMonthly (full inspection annually)

Ensure pressure gauge is in green zone and pin is intact.

Review escape routesAnnually

Every family member should know two ways out of every room.

Test garage door auto-reverseMonthly

Place a 2x4 under the door - it should reverse when it touches.

Pro Tips

  • Install smoke detectors on every level and in every bedroom
  • Replace all smoke detectors every 10 years
  • Keep a fire extinguisher on each floor and in the garage
  • Practice fire drills with your family twice yearly

Major Systems

Your major systems represent thousands of dollars in investment. Simple maintenance extends their lifespan, improves efficiency, and prevents costly breakdowns.

Cost of neglect: $500 - $2,000+ per system replacement

Maintenance Tasks

Clean refrigerator coilsEvery 6 months

Dust-clogged coils force compressor to work harder, wasting energy and shortening lifespan.

Clean dryer ventAnnually

Lint buildup is a leading cause of house fires and reduces drying efficiency.

Run dishwasher cleanerMonthly

Removes grease and mineral buildup that causes odors and reduces cleaning power.

Clean washing machineMonthly

Prevents mold and mildew that cause musty smells on clothes.
