Quick Answer: Start with the safety, water, heating and cooling checks that can prevent small problems from becoming expensive repairs.
What to check first
- Look for leaks under sinks, around toilets, and near water heaters.
- Test smoke and carbon-monoxide alarms.
- Replace or clean HVAC filters according to the manufacturer’s instructions.
- Clear leaves and debris from outdoor equipment and drains.
Seasonal routine
In spring and fall, inspect weather seals, gutters, visible ductwork, and exterior hose connections. Before extreme heat or cold, confirm that your thermostat, shutoff valves, and emergency contacts are easy to find.
Costs, maintenance intervals, and energy use vary by home, equipment, climate, and local service rates. Use this guide as a practical starting point, then check the manufacturer’s instructions and your local utility information.
When to Call a Professional
Call a licensed professional for exposed wiring, gas odors, structural damage, refrigerant work, or a leak you cannot safely isolate.
