What Your Neighbors Say About Us and "The Doty Difference"

"Working with all of you on the phone (Laurie) and in person (Arnold, Darren and Nick) was a good as it gets. The very first question everyone asked was "Are you staying warm?" (which warmed my heart immediately). The second question was "What can we do for you?" And the rest, as they say, is history."
-Marie R.

"I can't say enough good things about the staff and the service - both are excellent. It was great to come from the barn into a warm house! Bree and Sam are the best! The community is blessed to have your company serving their needs."
-Teri H.

"Hi Pete! Just wanted to send you a quick email to say thank you for being so professional and wonderful to work with. I did get the rebates from consumers energy and the Board of water and light, so I appreciate you guys submitting those. I also wanted to pass along a quick compliment from the person who came to inspect the AC/furnace mechanical work from the city of Lansing. When I told him who installed our furnace and air conditioning units he immediately piped up and said “you had the best company work on your house“. That really says something. Thanks again,"
-Sonia F

Thank you so much for returning my check... I really appreciate your kindness, honesty, integrity and you are a woman of your word! Sad to say, it seems to be rare qualities these days, especially businesses, and it's so good to know I chose Doty's.
I will continue to recommend your company in the future and the excellent service you provide. May God bless you!
-Mary E

"Tim went above and beyond his duty during our annual air conditioner maintenance check-up yesterday, diagnosing the propane leak that we have been trying to resolve for more than a year.
He arrived at our home after the plumber had been unable to identify the source of ta strong odor, similar to sewer gas. As I greeted Tim, I expressed my frustration at our failure to identify the source of our stinky-smelling basement. Tim immediately offered to take a quick look, and within thirty seconds, said we had a propane leak. He tested the water heater hook-up with a soapy water solution, and showed the plumber, who ultimately made the necessary repair.
The water heater repair was not Doty's responsibility, but Tim stepped up and helped us resolve what was an unpleasant and potentially dangerous situation. We greatly appreciate Tim and the culture of service and helpfulness that you have obviously ingrained in your staff.
Many thanks to Tim and Doty Mechanical! "
-Richard H., St. Johns

Justin, the technician, was a very nice young man, his manners were incredible, and he seemed very knowledgeable about your product line and how to service it! He also gave me some very helpful suggestions, which I really appreciate!
I hope to see you one day soon!"

By noon he had fixed the problems, a faulty wiring problem, and we were up and running. Not only did we get a quick response, but the repairman identified a problem that could have resulted in a fire. WE CAN'T THANK YOU ENOUGH!"
-Amy S.--Vice-President of Operations, MRI Network

"I just want to thank your sales and service staff for the great experience I had with my recently-installed furnace and AC units. It was a pleasure doing business with you.

I will definitely recommend you to others who need a furnace/AC repair or installation."

Thank you Darren and all of the Doty team for restoring my trust in the contracting world!"

"Your service tech, Will, went above and beyond when my furnace "shorted" on Christmas evening. Will arrived at 10 pm on that holiday and fixed the transformer giving me heat at 11:00 p.m. On December 26th something else "shorted" out and Will returned at 9:30 a.m. and stayed for almost 6 hours troubleshooting the "short" (which was like attempting to find a needle in a haystack). Will found the problem and the furnace began providing heat again. The service provided by Doty Mechanical was excellent and in closing, I would like to again commend Will, the service tech, for his stick-to-it attitude in locating the problem and (completing) it's associated repair. A satisfied customer."

"Last fall I purchased a heat pump from Doty Mechanical. I decided to go with their less-expensive secondary brand. Unfortunately, I have experienced several problems with it. Each time I called they immediately responded with a service call and fixed the problem... I mentioned that I wished I had spent the extra money and purchased their main brand unit. The next day I received a call from them informing me that they wanted happy satisfied customers. If I would be willing to pay the difference in cost as stated on the original quote, they would absorb the labor cost of removing the secondary brand heat pump and installing a new primary brand name one. This was even more than I hoped for.

Their staff is all very professional and courteous and my experience with them has been extremely positive.

Needless to say, I am very pleased with Doty Mechanical and would highly recommend them for anyone who has heating, air conditioning, or heat pump needs."

It’s been just over a year now since it was installed, and we continue to notice a positive difference in the air and dust in the house. An additional observation is that there appears to be even less dust now that the heat is on instead of the AC."

-Tyree D., Lansing

Subject: I LOVE your company!!!!
"Tonight, I volunteered to ring the Salvation Army bell at Meridian Mall with a friend of ours - she's 82 - and I couldn't believe she was going there alone. Her husband was going with Tom to the MSU women's b-ball game. About 5:00, we realized the upstairs furnace wasn't working. I called your office, then the emergency number. Arnold (?) came from Perry- I can't believe he got here that fast and fixed the furnace so fast... I was gone, but Tom and Ray still made it to the game. Tom tried 2 or 3 times to tip Arnold, but he wouldn't take a tip. Your service was THE BEST - and Arnold is as honest as they come. So - Tom and I are now home, warm and cozy!!! Give Arnold a big hug from us!!! Thank you so much!!! ME :-) "

The technician who came to my house today was not only prompt but friendly, courteous, professional and knowledgeable. I appreciated the way he explained to me, every step along the way, what the problems... were and how they could be fixed...

- Tim and Gail B., Okemos

"We have been very pleased with the service, and very impressed with the service representatives of Doty Mechanical. After having made the most recent purchase, your installation man impressed us very much. He showed great respect for our home and to us. This has become a lost art in this country. So often it is get in, throw the job together as quickly as possible, get paid and get out. Doty Mechanical does not operate like that, and because you care about customer relations even in these difficult times, it is our opinion that the customer will never be sacrificed due to economical slowdown or a way of just doing business. We thank you for your past service(s) and will continue to use Doty Mechanical as it becomes necessary."
