"All of my interactions with One Hour have been outstanding. From scheduling to execution of services requested. All of the technicians are excellent. They are courteous, on time and efficient. They came highly recommended several years ago and I am glad to continue to work with them."

"We have used this company for two years to install and maintain several systems in our house. They do terrific work and are always prompt, punctual, and respectful. We recently had two furnaces out just as it started getting cold. Scott Ruleman came out and quickly diagnosed the problems and got them back up and running. I also appreciate that he took care of some very gross work (pulling dead birds out of the furnace motor). Everything seems to be working well since the appointment. Thank you!!"

"Adam B. is our service tech and is always professional, considerate, knowledgeable, and informative. He does a great job identifying and explaining any maintenance needs, concerns, or available upgrades or products. We've been happy with our system that was installed and has been maintained by Modern Mechanical/One Hour Heating for 10 years and going strong!"

"These guys are all great. They always show up quickly and on time, they give me options without pressuring me to spend more than I need to. Unlike other companies that have come out I never worry about leaving these guys unattended in my house and my dog just loves them! Thanks for the great service!"
