Woke up early this morning to a frigid house and realized my furnace had stopped working. I tried to do some minor troubleshooting myself but no success. Core Temp had installed a new a/c unit at my house a few years back, so I decided to give Richard a call to see if there was any way he could come out today to look at it. I called around 6am expecting to get voicemail but to my surprise Richard actually answered the phone. Considering it was almost -30C outside, I thought they would be booked solid, but Richard was able get one of this techs, Eric, to squeeze me into his schedule today. Eric was courteous, professional, and friendly, and he got my furnace up and running again in no time. Couldn't ask for better service from Eric and Richard. Core Temp will always be my first call for any heating or cooling issues , and I would highly recommend them to anyone who would need their services. Thanks guys!
