Very happy with the entire Fred F. Collis & Sons experience. Mike the salesman is very knowledgeable and honest. Never did I feel pressured to buy something that was more than I wanted. The install team was top notch. Booties on their shoes and plastic on my stairs were some of the measures used keep my house clean. The system is working like a champ on these hot summer days. Genuinely happy with the service provided by the Collis team.
Great equipment and the best servo e in Utica Rome area.
Great company, polite, experienced, and friendly. Great price, and installed with ease. Great job and great people.
Helped me with some last minute heating oil on the same day that I called. Very accommodating and the women on the phone was extra helpful to make sure my needs were met. A++
