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++
customer for over 11 years, including a new furnace; but.....BE AWARE: even if you call to confirm the service appointment that day, YOU MUST SIT BY THE PHONE. because if you do not answer the call prior to the tech coming over, they will go to the next call. there is no prior warning of this when you make an appointment.
Fred Collis and Sons, Inc is very professional, courteous and helpful. After doing some research I found they had great prices in the area for oil and they were very prompt with delivery.
The service department who’s also very knowledgeable have been my go to for all my plumbing and heating needs. Thank you Collis for always exceeding my expectations!
Although not the cheapest quote I received. But every time I called with a question or concern my call was answered or returned. When expressed concerns or raised an issue they were resolved. Those things you can not put a price on.
Had a completely new system installed. Required all new duct work. The installers did an excellent job working with my requests, when several changes were requested. Never once did they hesitate to accommodate my request.
Extremely happy with the work completed and looking forward to additional work to be done in the future.
