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 setup 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. 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 services.
