Our central air stopped working at 1 pm on a Saturday afternoon. I called them based on reviews I saw online. Jason called me back in less than 5 minutes. He was on another call and said he'd be here as soon as possible. He showed up about 6pm. He was extremely professional and polite. He told me what he was looking at, and explained what he was doing the entire time. He had our air conditioner working in no time. He went above and beyond what we expected. I would recommend them to anyone needing quality work done to their heating and air.

I am so happy that I called Collier's. They were fantastic and fit me in, even although they were extremely busy. Robert came out and fixed my problem and I could tell his character and honesty were above reproach.

We bought our first Big Green Egg from Collier’s yesterday. They were so helpful, answered all our questions, and gave some tips. They had everything we were looking for and more. And a fast turnaround on delivery (these grills are heavy so delivery was an awesome perk). Thank you Collier’s!

The Collier's team communicated with us well and were very fast with getting us on the schedule. They lent us electric heaters when our heat went out which we ended up not needing to use but it was good piece of mind to have them there. Their pricing seems pretty average and the team is very polite.

From quote to install was only 4 days. We were told it would take most of day and in 4 hours they were done. Everyone was very professional, polite and explained everything thoroughly. Cleaned up everything completely and was very patient with all questions even if it was a repeat!

Very friendly nice people just waited 2 weeks on a part that wasn’t even the part we needed and then had to wait another week for the right part. Great people just not worth the waiting game.

Tried out the furnace yesterday .....in advance of what was forecast to be a night in the 30s.....and it was a no-go. Called Colliers, received the usual great customer service when scheduling, and Eric was here today ! Friendly, efficient and no nonsense.... had us up and running in no time ! We continue to be happy long-time Colliers customers...

Colllier’s installed a central humidifier on my furnace. They were in constant contact with me from quoting to scheduling to install. The 2 men arrived at 4:30 and were done by 6:30 and did a good job of installing and clean up. The install itself is neat and orderly and Trent made sure I was happy before they left. I only have 4 stars only because I haven’t been able to try the system yet, otherwise it would be 5 stars. I’ll revisit this review at a later date.

The team from Collier’s did an amazing job on our fireplace instillation from start to finish. Their pricing was fair, the product was of high quality and the install team made quick work of it. I appreciated… their attention detail and cleanliness. They left our home exactly as they found it and they treated us like we were family. Thanks again.

We had a great experience with Colliers. All personnel were prompt, knowledgeable and very conscientious about cleaning up after themselves. We especially appreciated their patience in explaining how our new fireplace works.

Well over a year later our geothermal unit is running great, with zero thanks to this business. Obviously a new furnace was not necessary, all that was needed was an actual honest business to fix their "mistakes". Attached an example of their "work", luckily it didn't catch on fire.

Never been so disappointed in my life. Had issues with heating on north end of house. They installed a two stage furnace knowing my ductwork was too small. So they initially cut an opening in my return plenum in the basement knowing that wouldn't recycle the house air. Then when I complained they installed another return air closing the opening for more money. That didn't help so they said get someone else to insulate the ducting. "We were only selling you a new furnace."
