I had Cassel come check my furnace last week. The unit had been in the house for the eight years I owned it. They came on time, even a few minutes early to the appointment and set to work doing their maintenance and inspection of the unit.
All was going well until they found two of the three heat exchangers were cracked. This can cause carbon monoxide to enter the air ducts. I was willing to get it fixed, but they offered a more than fair price to have the entire twenty year old unit replaced. And they did it that day!
The installation technicians arrived at 10:30am and had my new furnace installed and tested by 2pm. The service techs were affable and true professionals for their entire visit. I'm very satisfied with the quality of the install and the expertise showed by all the technicians that I interacted with.
I'm always a bit leery of technicians and how they price things, but Cassel offered a same day install at a price that was more than fair. Highly recommend them.
