"The Repair Technician was excellent! Not only did he arrive before the appointment time; but he was courteous, efficient and very knowledgeable. He answered all my questions without hesitating and explained why the problem had occurred as well as alternatives to fixing it. I am very happy with the repair as well as Dennis and Comfort Solutions."

"I highly recommend this business. The technician, Pierer, and his colleague were true professionals and incredibly courteous. Even though I was their last appointment of the night, they went above and beyond to source a replacement part that wasn't stocked on their truck. I truly appreciate their dedication to getting our HVAC unit running late in the evening. Thanks to them, my family was able to sleep comfortably with the heat restored."

"Due to allergies that have been progressively getting worse my doctor prescribed singulair early this past summer. Unbeknownst to me, a big part of the problem was the air quality in my own home. I happened to need help with my pilot light last week and realized that I was breathing in some nasty stuff due to the condition of my still running circa 1978 heater. Needless to say I made the decision my health was worth the investment of a new HVAC system (and I wanted EVERYTHING replaced). I now have a MERV 11 filter, UV light and new duct work, everything. The unit is up and running and no runny nose or headache. I am soooo glad I made this decision. Their price was VERY competitive, they were very professional, and all in all it was a much better experience than I expected. Thank you Allgood!! If I could I would give you 6 stars."

"This positive review only pertains to the last tech, Jeananne, who did my regular service maintenance on 4/25/2022. She was thorough with the inspection of my units and gave great feedback. Customer service is the key to success of any business! In the past, ARS has been sorely lacking in customer service, I could write a book about it, but it seems that the company is turning a new page and engaging the customer as I would expect. I hope ARS will continue to hire more techs like Jeananne to ensure they are successful by keeping their current customers and also having them recommend the company to friends and relatives."
