“Again,I must commend your staff and business on our furnace install.Your staff showed up on time, were very courteous – answering all of my questions and they cleaned up after themselves. We are very impressed with the work and dealings with your business. Your receptionist is always very accommodating and pleasant on the phone.”

Lance and Liz R.

“I used to heat my home with a pellet stove. I could not get someone to service it, even though I told them it was my only source of heat and it started on fire. Called Bagniefski’s for a furnace quote. Came out the next day. Sent the proposal the next day, I signed it and they scheduled service as soon as I was available. Now four days later, I have heat because they were concerned about me. Good thing, it is 20 degrees at 1 pm and I am finally warm!”
