What are the most important home systems to maintain?
HVAC, plumbing, electrical, and roofing have the biggest impact on safety, comfort, and cost. Stay on top of filters, leaks, and annual professional service.
How often should I have my HVAC serviced?
Schedule a professional tune-up twice a year—before cooling and before heating season. Change filters monthly and keep outdoor units clear of debris.
When should I call a plumber vs. DIY?
DIY: unclogging drains, replacing faucet washers, testing shut-off valves. Call a pro for sewer issues, water heater problems, low pressure throughout the house, or gas lines.
How often should I test GFCI outlets?
Test GFCI outlets monthly using the test and reset buttons. They protect against shock in kitchens, bathrooms, and outdoors.
How often should I have my roof inspected?
Have a professional roof inspection at least once a year and after major storms. You can do ground-level checks and attic checks yourself.
