I would highly suggest you call your local Sears (or 1-800-4MYHOME) and see if they have Kenmore furnance installers in your area. You will pay more upfront, but they are backed by an excellent warranty and will provide years of maintenance free worry. Best of all, for what little maintenance is needed, Sears sends someone out each year to take care of it for you.

You get what you pay for!
