24-hour emergency service

A cold house at 2:30 in the morning.

Dan and Renae had just put their 18-month-old back to bed when they found the furnace wouldn’t run. This is how the night went, from the letter they wrote afterward.

“It meant so much to us that we did not have to wake our children and take them somewhere until the furnace could be fixed.”

“They did not push a new one.”

Customers keep making the same point: if the old furnace can be fixed, OK Heating will say so.

Great service ahead of Schedule

“Service came out the same day to look. Needed a new AC unit (was not surprised), Scheduled for the following Tuesday and got a call that they were coming Monday. Very happy with the whole process, and to have AC again!”

“Impressive customer service and response time. It was Saturday morning and I left a message on the emergency line. Within thirty minutes the owner had called me back and arrived at my place and by another thirty minutes the repair was done! Within one hour everything was taken care of. Thank you so much OK Heating and Cooling!”

Professional Installation

“Our installation of a high efficiency furnace and AC unit went very well. Cody and Brad did a great professional job. They really paid attention to the little details, communicated well, and cleaned up the work site. They made sure we had heat by the end of the day and returned the next day to complete the AC unit. Working with the staff at OK Heating was a very positive experience.”
