4. What should I know about the heating and cooling systems?
A good home inspector will look at the dates on the furnace and boiler maintenance stickers to see if it’s had a lot of service calls in a short time period, which isn’t a good sign. If the the unit is old and greasy, the inspector may recommend getting a replacement.
Remember these systems don’t last forever. the average lifespan of furnaces is about 15 years, water-heaters last about 10 years, and air conditioning units only last about 6 years. Note the date on the sticker and then figure out how long until you have to replace each unit.
