These guys were my second call when my furnace stopped working properly. The first company I used sent a tech out who said the furnace needed to be replaced, and gave me a quote, but said he "jiggled a wire" and got it running again for the time being.
When it went out again the other day, I called Ray N. Welter. Their tech, Ralph, fixed the problem in half an hour. He told me the furnace is pretty old, but his fix should get me through the winter "and maybe a couple more," and then gave me a quote that was lower than the first company.
These guys are rad.

Furnace stopped working. When that happens after hours you learn a lot about companies. Today I called RW and got a person on the phone that knows about furnaces and he dispatched a service person Phil within 2 hours. I called them based on personal refer and reviews. They are excellent. Despite having a very old furnace it was the second time that this company said I did not need to replace. If I did replace it I want a Trane and RW would do to the work. For now I will call them for fall/spring tune ups and love that they don't have the club memberships etc. Just good solid customer service for all customers. A really ++ experience. Family run business with integrity.

If you need superior service this is your company!!! We were in Florida experiencing our first year as "snowbirds" when our furnace (in Bloomington) stopped working. Rick Welter personally took our call and not only sent a technician to our cold home, but checked on it for the next two days until our new heating unit could be properly installed. Phenomenal service!
In addition to the great service, their pricing was very competitive. I highly recommend this company for all of your heating or A/C needs!!!
