Having come back to a cold house after spring break, I phoned the highly rated companies, after normal working hours, to see if I could get someone to come out and assess. Even though I did not leave any messages, Jonathan returned my call, and set up an appointment for the following day. As he was finishing his previous job earlier and phoned to see if I was available to start early. The repair was completed that day after picking up a spare part. He also gave some advice on the running of the furnace etc. Very helpful, and well-deserving of his 5 stars. He now has our business for heating and cooling in Chaska, MN.
