Four in five Naperville homes were built between 1970 and 2009. That puts a lot of furnaces and air conditioners at or past the end of their first life.
A furnace more than 10 years old may be nearing the end of its life, so an original unit in a house from the 1980s or '90s is on borrowed time. We repair it if it is worth fixing, or quote a new one for free.
Central AC typically lasts 12 to 15 years. If yours came with a house from the 1990s or 2000s and is running long or blowing warm, start with AC repair and an honest answer on replacement.
Naperville has had two major floods, in 1996 and 2013. In 1996 the city got 14 inches of rain in under 24 hours. If water ever reaches the furnace in your basement, have it checked before you run it again.
For equipment in its second decade, a spring AC tune-up and a fall furnace tune-up catch worn parts before they become a no-heat or no-cool call.
Repairs first, then maintenance, then new equipment when it's the better value.
