I got home and was greeted with a cold house! Knowing that nighttime wasn’t going to make it easier to stay warm, I called Capital Heating. Their “On Call” person, Mike was busy and couldn’t come till maybe 9pm. I was thankful for any time slot on the same day. He called about 8:35 and said he was about 20 away. When he arrived, he went to work not only fixing my furnace but describing in detail how it works and why, on this day, it was not. I could not have been more pleased. Thank you, Mike, for helping me have a warm night of sleep.
