We appreciate the response to our call, as the temperature was to get down below freezing tonight.
Jim came out to our house this evening to replace the main limit on our furnace.
He was very polite, professional and answered all of the questions we had about the repair and proper maintenance of our heating system.
Thank you for providing such excellent service.
The person who came in to clean the furnace was very knowledgeable, and gave me several helpful hints for future care.
