Your furnace is about to take a summer-long break. Prepare it for prolonged inactivity by doing the following each spring:
- Clean area surrounding furnace
- Remove stored items so furnace has about 3 feet of clearance
- Wipe down exterior of furnace with damp cloth
- Change air filter, which is necessary for efficient and effective AC operation as well
- Switch off pilot, which will save you money on gas all summer
- Test carbon monoxide detector, keeping in mind that it has a life expectancy of 5 to 7 years
