Whats the word on Oms Inc.? Here is what some of our customers are saying

“I can't say enough good about Glen! He showed up on time, correctly diagnosed the problem and resolved it right away. I had already dealt with another AC technician who ripped me off and never figured out why my AC didn't work. Glen was very conscientious, answered all my questions, made sure I understood what the problem was, what my repair options were, and fixed the system. After almost 2 weeks without AC, it was wonderful to wake up in a 70 degree house instead of a 79 degree house! He cleaned up everything he touched and left the house like he found it. He called the next day to make sure we were happy. I wouldn't hesitate to recommend his services to anyone."

“This job was to service and certify the furnace and service the AC. He and his assistant were considerate and easy to talk to. Took their shoes off at the door and cleaned up after themselves."

What a great group of people to deal with!
Glen was friendly, knowledgeable and informative. He spelled everything out for us and gave us all our options.
The install guys were really hard workers. They finished the job in one day and kept me posted on what was happening throughout the day.
Right now it's 90 degrees outside and I'm cool and comfortable in my home.
I would highly recommend Glen and OMS for any air conditioner or heater jobs.
