Collis Heating and Cooling is just plain amazing. Over the years we've had them do yearly services, installation, inspection and emergency repairs. Top notch service. Everyone is very friendly, informative and helpful. I definitely recommend them. Well - if you want things done right, in a timely fashion and with a smile.
I called Collis for furnace repair and they were awesome! They were able to send someone right away and had us up and running in no time. The guys were friendly, knowledgeable and followed up with us the next day to make sure everything was good. Great service.
We called on a Saturday morning. They were very busy but kept us updated. The technician Jim, who was very nice, came out at about 5:30 pm. The pilot light on our furnace was out and we couldn't get it to relight. Jim worked on it for a while and finally got it going. Unfortunately, about an hour after he left it went out again. My husband was able to get it going the next morning. I called Collis back and let them know the fix didn't hold. Dave was very apologetic and said we would not be charged for the service. I was impressed with their customer service, and if we ever have an issue in the future I would not hesitate to call them again.
We bought a home and had another company perform duct cleaning but still had a musty odor when the furnace ran and our allergies were terrible. The home is 60 years old/Furnace 1 year old. Called Mike Kowalczyk and scheduled a duct cleaning service . Anthony, a very professional and polite tech, arrived on time the day of the cleaning and spent the day cleaning and sanitizing all of our duct work. No mess/debris were found in the basement when he was done. Its now 2 weeks later and No odors, Allergies are now much better. Great Job Anthony !! Highly Recommend this company! Very Professional, They do the job correctly and completely. Could not be happier!! .
