Best Boiler Installations in Denver CO

We have used Horizon for 20 years. Always professional.

Great job, quick triage and resolution. Provided advice to monitor and hopefully minimize future issues.

Blue Sky recently installed a new sump pump - Matt was extremely professional and made me feel very confident in the work that was done.

Good Company, Great service, and very professional service!!!!

Thanks guys

Matt explained everything in detail. The service was great.

Brendan was outstanding. He came on Saturday and Sunday for an urgent issue. He was knowledgeable, professional and communicated clearly throughout the entire process. He was very attentive to detail and thorough. We will definitely use them again!August 2020: we had additional plumbing work done by Will which was outstanding. Great work and very knowledgeable! Outstanding customer service.June 2021: we had additional work done on our A/C. Chris did a great job - helpful and knowledgeable!

We have had Dale out twice for the yearly service maintenance of our tankless boiler/water heater combo and we wouldn’t trust anyone else. He arrived on time, summarized the work he was expecting to do, how long it would take, brought extra parts in case and all the necessary tools, including a shopvac to clean up any mess. The extra part was not needed nor was the full-service flush. He explained when we would know that is needed (it will flash “SERV” once we reach the 4,000 hour mark) and how much time we have after that code appears.

Dale had a death in the family over the weekend but still arrived on time for the service when I would have expected him to reschedule (understandably, under the circumstances). To me, that says A LOT about his work ethic and character. Our new rescue dog that is usually scared of men would have happily jumped in the van and gone home with Dale when he left! Our rescue was underfoot, chatty and definitely wanted Dale’s attention for pets, even sitting “pretty” asking for attention. Dale was very patient and sweet with our special boy. Dale is 5 stars! Thank you Dale!

The service and professionalism is great. Will use To The T Plumbing & Heating in the future, they are definitely recommended.
