    Assured Comfort for 15 Years
    Assured Comfort has been the company we turn to for our heating/AC and plumbing problems. We have used them for at least 15 years and have a yearly contract to monitor our HVAC. Today we got to meet one of their excellent servicemen, Josh Proppell, who came to do exactly that. He thoroughly checked the entire system, inside and out. He was extremely knowledgeable and very friendly. It was a pleasure to have him do today’s system check. I feel assured that our system will get us through the winter with no difficulty. Thank you, Josh.

    They crushed it.
    Loved my experience with this company, they were really honest and informative (thank you to Guy who came out to give us a quote and really broke it down for us). They came out 2 days after we booked and finished the job in one day. Jay and Craig were so awesome! They were so nice, considerate, and very, very thorough. They crushed it.
    Billy Cahill
    Excellent Customer Service
    Craig and Jay were awesome! Very professional, kind, and courteous. They made sure the job was done right and that we were satisfied with everything before they left. I feel confident that we went with the right company to provide us with our new HVAC system. We were happy to give our business to a company that provides excellent customer service and also takes care of their own employees. Guy - the project manager was also great! He came out to talk with us about the initial assessment and what needed to be done. He was very pleasant and transparent with pricing, which we appreciated. He worked to win over our business and instill trust and confidence that we were in good hands with Assured.

    Fantastic service!
    20-year-old hot water heater finally gave out on Friday morning. Called Assured and they were able to come out Sunday morning to install a tankless system. Our tech, Ken, was fantastic. Kept me in the loop throughout the install, pointed out a few electrical issues that needed to be remedied, and gave me a good rundown on the system and how to properly maintain it so the warranty doesn’t void. Fantastic service!
    David Ernst

    We called at 5:30 p.m. when we got back home, and it was super hot because the AC had gone out. Michael Simmons came to see us a couple of hours later and stayed until our unit was working and he figured out the problem! Very friendly and reliable. We signed up for the membership after the service we got.

    Mikel did an excellent job
    Mikel Resto arrived on time to do the air duct cleaning at my house on Saturday, June 7, 2025. His air duct cleaning was intended to remove the dust, debris, and contaminants from my air ducts. It had not been cleaned in many years. Mikel did an excellent job and was a great resource when I had some questions about my newly installed AC system. Thank you, Mikel!
