"I originally hired Temperature Pro for my AC/Furnace maintenance. Every time they come I get more than my money's worth from their mechanics. Everyone is not only kind, but very knowledgeable. They always offer me multiple solutions (including usually one that would cost me no money) when they find small issues. The worst moment at my house came on Dec 23, 2023. Furnace went out as we had the horrible snow storm and we were supposed to host a holiday party. Shawn from TP made sure to work me into the schedule that day after facetiming me to see if he could detect an easier fix that wouldn't require him to come out. Needless to say, he made it in time, got it fixed and no guest knew the difference. I cannot recommend Temperature Pro enough!"

"I am a new customer with Service Professor, Inc. as of May 2021. In each of three service calls for routine system checks of my HVAC, plumbing, and furnace systems, I couldn't have been more satisfied with the professionalism of the individual tradesmen or with the customer service communication provided by friendly and patient office staff. This review is being posted especially to praise the exceptional routine service call provided by John Courtney on 10/11/2021. John presented as being a good listener and one who genuinely enjoyed his work and serving others. For example, he listened carefully to my questions and responded with detailed information that I could understand easily. And, after I commented to John about my previous positive interactions with Service Professor, Inc. tradesmen and with customer service staff, John responded by stating he has worked in the heating and cooling trade for 12 years and felt very fortunate, as a newer employee, to be able to work for an organization such as Service Professor that places caring and quality customer service communication among its most important priorities. I hope my comments encourage anyone seeking HVAC, plumbing, or furnace routine service or repair work to not hesitate to contact Service Professor."

"They were here the next day, and installed the furnace in two days, just enough time to wait for parts. They were fast, clean, and their work was great."

"Since we have lived in this current home, Crome Mechanical Heating & Cooling has installed a new Lennox high efficiency ductless ac/heating system and a Lennox high efficiency boiler. Both units have performed very well in a cost effective manner. Meanwhile, I am certain Crome Mechanical will maintain our equipment at a high level of service."

"Did a great job, cleaned up when they were done. New furnace works so much better than the old one. We are looking forward to the savings of an efficient furnace."

"During early Dec 2013, during one of the coldest winters in Michigan in 30 years, my furnace was having trouble keeping the house warm so I called Grand Ledge based Aire Serv to do a furnace check-up based on a coupon. They came out quickly and found a crack in the heat exchanger on my 20 year old furnace and shut it off, saying it was unsafe to run. Apparently it was about twice the BTU capacity than needed for the house and the constant shutting on and off had taken its toll. I was not the original owner so I am not sure why they over-sized the furnace.
I asked for quotes on a new furnace on the spot and they tried to sell me a $17,000 furnace and said no enough that the price came down to around $6,000. I really didn't like the very rehearsed sales pitch. It was so focused on how much better their warranty and service was compared to others that I knew it would be pricey. I really wish they had just laid out all their models and the features and prices and just let me pick my comfort level in features and prices rather than a sleazy sales pitch. I recommend you force them to skip the sales pitch and go straight to the facts.
I didn't have time to shop around and the house was very cold so I purchased one that night. They left some infrared heaters at no cost to help keep at least one room warm. I really appreciated that they offered to work a Saturday so we could have heat as soon as possible. They installed everything on time and as promised and were very nice. No complaints on the install experience at all.
I went with a two-stage Amana furnace at half the BTU of the previous furnace. It had no problems keeping the house warm during the rest of that very cold winter. I like the two-stage motor and have to set to always run on low when not heating or cooling. That keeps the air moving through the house for more even temperature and greater comfort - it really is noticeably better than on/off heating.
The exhaust venting couldn't go where they planned due to an unseen obstruction and so they had to vent it somewhere else that was a longer run and required extra work to get outside of the house. They did the extra work at no charge as promised.
Bottom line - they are an excellent company that did high quality work and kept all their promises and gave me an excellent product that fit my needs well and did it all on a tight timeline.
My only complaint is that since I was without heat, I feel I had to pay full price.But that is not their fault - that was mine for letting the furnace go bad and creating the emergency where I couldn't comparison shop.
When they sent me the post-installation survey, I sent a full response equivalent to what I have written here. They never responded back to me.
