Frequently Asked Questions About Furnaces

Is servicing my furnace important?

Annual furnace tune-ups are an essential part of maintaining the furnace. Before the manufacturer can honor a warranty, they will first ask you for any proof which shows that you have been servicing your unit. Most, if not all, producers of these systems provide an instruction manual with every unit. The manual will explain to you how the unit should be maintained.

When should I schedule the furnace repair?

Ideally, servicing should be done on an annual basis. However, if the furnace develops a problem at any other point, the wisest thing to do is to call a professional as soon as possible. You want to avoid having to pay more at a later stage because the issue will have worsened. So, make sure that you call an HVAC company with an excellent reputation to handle any problems with your unit before the problem gets worse.

When should I replace my furnace?

The standard for many models is 15-20 years. So, if the unit is well-maintained, it can last for over ten years. Furnaces that do not receive regular maintenance will last far less. That means all things going well, you will not have to worry about saving for a new furnace before your current unit reaches ten years or so.
