Patrick and Wyatt were absolutely wonderful. They were extremely professional, polite and early to our appointment time, which was much appreciated! We plan to hire them again for future projects. Service 1 definitely has a customer for life!

Thankyou Mike for fixing our issue with a hot new installation pipe. He went above and beyond to make it safe with our young children in the house. He put a guard up in front of the pipe for a shield. 😊 Thanks again!

Technician was on time, even a little early...went about his routine and tested my unit and explained the problem. Was not pushy nor did he try to sell me a new unit. Our our heating system is 20 + years old and we asked for an estimate to replace ..he took pictures and measurements for replacing out existing heating unit along with a great far, we are very happy with Comfort 1

Patrick came by on short notice to fix a problem that a Home Depot subcontractor left us with. He was prompt, friendly and knew his craft. Will absolutely contact Patrick again for any plumbing concerns in my home and recommend him to family/friends.

Mike was great! He communicated well about when he would get to our house and was able to tell us what the problem was quickly. He was honest and professional. He was able to fill our refrigerate and get us back up and running quickly.

Since Shawn installed the new Honeywell filter and Aerus Air Scrubber System we have NO dust and NO sneezes. What an amazing improvement in our daily living. Also, many thanks to Jim for recommending this system.

Called Service 1 to get someone to come out and look to why our AC and Coils had ice on them after a period of time. Scheduled an appointment for 6 to 8 pm but was surprised that David was able to come out around 1 pm and diagnosed the issue was with the AC unit and found it low on coolant. Since the AC was about 20 years old the coolant could not be obtained for it any longer. Since there was extremely low coolant, there had to be a leak of some sort as it had been several years since it was last needed. Due to the age of the of the AC unit, the Furnace was 20 years old as well. Instead of doing 1 it was decided to do a complete new furnace and ac install. The work start just in a few hours of the decision. The Install Techs came out and got to work. Both Shaun and Randy were very professional and got the job done within a few short hours. I really enjoyed watching them and I learned a few things along the way and came to the conclusion that i'll just leave all this up to the Professionals, LOL. Thank You Service 1 for being so on top and putting Customers as your top priority. Getting same day service like this to me is unheard of. You typically have to wait a few days or week(s) to get a huge job like this done. Great Job and thank you!
