On behalf of the members of Crossroads Community Church, I wanted to first thank you for the time you spent coming to our location. Assessing our heating needs and writing a proposal on January 20th. We understood that you endured some challenges in receiving our needed equipment in a timely manner. Regardless of the challenges set before you, you succeeded on our behalf extremely well. On the morning of January 25, your technicians, Carlos and Chad, arrived timely and went right to work. We would like to state that they represented your company well. They demonstrated knowledge and efficiency; in addition to professionalism in their conduct with us. Thank you for solving our heating needs and for the payment arrangements you extended to us.
