"During the sales process I had many questions regarding the efficiency of the system being recommended for installation. Jim, the owner of the company was patient and clear while answering these questions. He explained his reasoning for what he had suggested we purchase. The men that installed our new central air were polite and business-like. When done with the installation, they cleaned up their work areas. There was nothing left behind for me to clean up. After the installation, Jim came back out to inspect the work of his men. He checked with me about how satisfied I was and again answered all of my questions. I heartily recommend Maximum Heating and Cooling for any and all services they offer."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"Ac not working and thought it was compressor so found a company that would come out on Sunday. Spoke with tech and he was knowledgable and gave me a good deal of info. The after hours charge was high at $140.00 but it is a hot Sunday so the fee is what I expected maybe a bit more but they were one of few who would come out for an emergency. Ok perhaps no ac is no emergency but still. Lol Tech diagnosed the problem and it was a bad capacitor and he added freon but just a bit. Part cost was $215.00 or so and I researched the part and it only costs $40.00 new but I have zero experience with hvac and I am paying for their expertise plus they had the part etc. it costs what it costs and if you know about these things then yea it would be much less but it is less than a whole new system. I would call them again and there seems to be a wide variety of opinions on internet about that cost but they are a big company and I am paying for their expertise just like my clients pay for mine.

"There were several problems with the space pack AC unit AC Engineers installed in 2016. AC engineers really stands behind their work. Their technicians are excellent. It took several visits to restore my system but AC Engineers did the job right. I live in a 100 year old house and repairs to my boiler and AC and other systems are a fact of life. AC engineers is a pleasure to work with and I have no reservations to recommend them to a friend."
