Jonny and crew do great work and always have the customer in mind!
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++
I wanted to have my heating oil boiler replaced with a high efficiency direct vent propane boiler. I called several local companies to get estimates. I took all the estimates and looked at each company. I wanted a company that could service what they sell. My previous boiler was installed by collis, and when I had issues and needed service they were always here quickly, the techs were always friendly, and they always made sure to keep my house clean. I narrowed it down to the three best estimates and companies. Collis not only gave me the best price., but their scope of work far exceeded the others. The system in my house is very complex . They did an amazing job and the installer Kenny did a beautiful just with all his copper work reloacation the boiler and wiring. I highly recommend Collis. Dave Collis came out several times and desgined a beautiful system. The installer Kenny and techs that came out to help him not only did an amazing job but are very courteous and friendly. Highly recommend them!!
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!
