Mainline Heating & Supply
Rated 5/5 Stars Based on 10 Customer Reviews
I want to thank you and your company for a great job in the installation of my Regency I2400M insert last Friday. The insert looks beautiful and the installation seems very solid. Your technicians, John and Brian were very courteous and careful in their work. I have a nice wood floor in my living room and the first thing that your techs did was to cover it with tarps so it would not get dirty or scratched. I was here and watched the process from start to finish and the job was done very professionally. The town inspector comes this afternoon, after which I am looking forward to our first fire in the insert. Thanks for a job well done.
