He came out last minute because the furnace was not working properly. He answered the phone outside of normal working hours. He figured the problem out quickly and fixed it just as quick. Would highly recommend!

He came to our house to review the problem. He has not replaced the furnace yet (our choice to wait a bit) but his response was immediate and he was professional at our home and with the provided quote.
