This company has scammed us out of over $200 for a "In-depth inspection" on our heating system. This was months ago but we were using this company for servicing our A/C and heating unit for about a year and a new technician had thought he found a crack in our heating unit. This was a new unit and so we wanted to make sure we were safe even though a crack was unexpected. He showed us a picture of a line that did not seem like a crack but he said he spoke with the manager and they both thought it was a crack. They told us we needed to get a more indepth inspection to make sure as this can be very dangerous. So we paid over $200 to get this in depth inspection by another employee which took him about 15 mins to open our unit and to tell us that nothing was wrong with it. He said our unit looks new and the "crack" is a normal line and build for our newer unit. He said that they previous employee probably did not know what he was looking at since its a newer unit. So i paid over $200 just because their employee and manager did not know what they were looking at? The lack of experience costed me over $200. I brought this up to the manager and she said wanted to make sure for the "safety of our family." I am not sure if we got absolutely scammed or they lack the experience which costed us unnecessary money. The manager gave us a credit of like $35 to make us feel better.

Avoid this company especially if you are not knowledgeable of your A/C and Heating units. They can take advantage of you. I want to make sure there is awareness of what they are doing.

Response from the owner:Thank you for your feedback. We understand your concerns and want to take a moment to clarify the steps that were taken during your visit. During your preventive maintenance service, which includes cleaning and verifying proper system operation, our technician observed what appeared to be a possible hairline fracture in the heat exchanger. Because heat exchangers are a critical safety component, even the possibility of a fracture should be investigated. A cracked heat exchanger can allow combustion gases—including carbon monoxide—to enter the air circulating through your home. This can pose health risks and can also increase the risk of further equipment damage if left unaddressed. To ensure proper function or lack of, the technician performed an initial test at no charge to help determine whether a fracture was present. Based on those findings our office discussed additional options with you. You then approved moving forward with Secondary Testing. Testing was performed using industry-standard methods to identify small or hard-to-detect fractures in heat exchangers. To help offset the cost, we provided a 25% discount on this service, along with the additional $35 refund you mentioned. At no point was there any intent to mislead—our recommendation for further testing was based entirely on the potential safety concern and the responsibility we have to ensure your system is operating safely. We always aim to be transparent, thorough, and proactive when it comes to our customers' comfort and safety. If you have any remaining questions we are more than happy to go over everything with you.

Mise Guys were very helpful in repairing my mini split Ac unit. Will call again if need arises.

Karen Winn

From Treacy to Jay to all of their team, we have had nothing but excellent quality work and service from Empire. Our old system was a maintenance nightmare, and expensive to fix. With our Empire systems, we finally have the heating and air conditioning we're happy with. Thanks guys!

Response from the owner:Hey Karen! We loved redesigning and optimizing the HVAC for your beautiful home. But we loved working with you and Mike even more! We're thrilled that our paths crossed and look forward to serving you for a lifetime! Thanks for the kind words. :)

Mark Buettner

Nick was helpful and professional.

Bill Davis

Hard to believe it is 2026 now. We have been getting outstanding service from these guys/and gals all the way back to 2017. Back then, they were Viking Mechanical, then it was Empire Heating and Air and now they are the Mize Guys (Mize Family owned business). That is all the more reason to support them!!!

During this period of time, we have had every 6 mth service (Spring A/C and Fall Heating) on the original 2006 system that was built into our home (NO, Mize did not install the original system and we could not wait to get rid of the original contractor either). Mize was our first and only choice for the new HVAC replacement system install.

Tremendous cost savings on the units so we joined their "Wisest" Protection Plan which gets you (2) two scheduled visits a year, a 15% discount on all repairs, pre-season scheduling, replacement filters, and most important, Priority Service 24/7.

To top it all off, Connor is their son and did a tremendous job with our install in Jan 2025 and now with our service every 6 months. In fact, Connor was just here last week.

Response from the owner:Thank you so much for your continued trust and support over the years—it truly means a lot to us! It’s incredible to hear we’ve been able to serve you all the way back since 2017 through each chapter of our company. We’re especially glad you’ve been happy with your maintenance services and your new HVAC system, and that the “Wisest” Protection Plan has been a great fit for your home. Connor will be thrilled to hear your kind words—we’re proud to have him on the team! We sincerely appreciate your loyalty and recommendation, and we look forward to taking care of your home for many years to come.

Cindy Faatz

I was able to get an appointment quickly to repair my heating system. Nick was professional, knowledgeable and very customer-service oriented. He walked me through each step he was taking and was able to diagnose and fix the issue quickly. I will be calling Mize Guys and requesting Nick for all my future HVAC-related work.

Response from the owner:Thank you so much for your wonderful review, Cindy! We're thrilled to hear that Nick provided you with such professional and knowledgeable service. We look forward to assisting you with all your future HVAC needs!

Brecken Walther

Steffanie Wood

Very responsive company with great representatives. Coral made the appt to meet my needs and was super helpful. Tech Nick arrived within the time window provided and quickly diagnosed the heater problem with professional ease. From inception phone call to diagnostic visit the service was the best. I will definitely have Mize Guys perform maintenance and other recommended preventative services. Couldn't be happier with this service that exceeded my expectations.

Response from the owner:Thank you so much for taking the time to share your experience! We’re thrilled to hear that you were happy with our customer service and quick response. Providing timely, reliable service is very important to us, and it means a lot to know it made a difference for you.

Ray Abbitt

I called 10 companies that supposedly offered "Emergency Service" 24/7 and none of them could come on Sunday. I called Mize and talked to Conner and he was here less than an hour later. And less than an hour later my furnace was working again.

Response from the owner:Thank you so much for the great review! We’re glad we could respond quickly and get your heat back up and running. Providing fast, reliable service during no-heat situations is something we take seriously, and we truly appreciate you choosing Mize Guys Heating & Cooling. If you ever need anything in the future, we’re always here to help!

Nick was great

Response from the owner:Debi, Thank-You for your review, its always a pleasure to hear from our clients. We are glad to hear that Nick was a pleasure to work with.

Joe Keeper

These folks are first class. Absolutely everything was wonderful…from my cold call with Coral (the phone rep), to the bid, to the install, to the follow up. I would 100% recommend Mize.

Response from the owner:Joe, Thank-You for the wonderful review. It is always a pleasure meeting and working with new customers. We look forward to many years of conversation with you and your family. Please reach out should you have any questions.

J S

Absolutely no other reason to call anyone else! Fast response. Found the problem in 20 minutes. Two other companies spent days and hours, frying the new parts they installed. What a relief to find “friends” in the HVAC business.

As an updated follow-up: “Are you elderly, like me? Or do you have senior aged loved ones?” Mize Guys Org and its employees show a special affection and a sincere concern for those who are vulnerable, or insecure about approaching a company regarding their HVAC “mysteries”. Their Techs have become our friends, always welcome in our home. Never! Never! will you need to worry or be suspicious. “Now isn’t that just how it’s supposed to be?”

UPDATE PER Our most recent bimonthly inspection: Referencing Christian & Nick; These “Guys”, are “sooo” professional, and so sincerely friendly and accommodating, for us having gained two new friends that all there is left to say is the following: 1). 100% satisfied (cost, quality-workmanship, speed of completion, educating using understandable explanations, no salesmanship pressure!, and they demonstrate a sensitivity to home surroundings protecting it against the work environment). 2). Just use them and see for yourself. You’ll agree with above.

Response from the owner:Can't thank you enough for the kind words and vote of confidence. We're so happy to have gotten to the bottom of the issues and get you up and running. We appreciate having you as friends as well. Community is everything! Thanks again for the work. : )

jill chesla

Had Mize guys come out to look at my A/C unit and there service tech did a great job explaining and diagnosing what was going on with my system he was very up front and honest ! He explained what it could need in the future without trying to sell me on somthing i didn’t need at this time in the end it was a simple issue that was resolved through his thourogh diagnostic procedures! I will have them back for any future HVAC needs

Went to Mize Guys since they bought out Empire Mechanical. Had great experiences with Empire, cannot say enough.

Recently had Mize out when our AC stopped working and they wanted $1,300 to replace breakers and update electrical insisting nothing was wrong with the unit. Got a second opinion that found a leak in the coolant line and cleaned a connector, unit fired right up and cost less than $200.

Recommend shopping around.

Julio Ortiz

We have been using Mize Guys for our commercial and residential services exclusively
Mostly because

Customer service is outstanding work is excellent stand by their product and go above and beyond.

I have used plenty other HVAC companies in my kind of Business, which did good work, but nothing compared to the Mize Guys The crew are excellent and what they do they communicate with you on every step of the way and if they can’t get just a repair done, they’re fair on telling you whats wrong give you recommendations and Solutions

So my recommendation if you need HVAC service, don’t always look at the big box names give Mize guys a call promise You, you won’t be disappointed

Julio

Terry Poore

I can’t recommend The Mize Guys strongly enough. They installed a new wine cooling system over two and a half years ago which stopped working recently. Although it was definitely far out of warranty, they stood by their work, persuaded the equipment supplier to replace the failed component, out of warranty, and got the system running again for a very reasonable cost. Throughout the process all the staff were very professional and friendly.

Response from the owner:Thank You Terry for your 5-star review! We truly appreciate your patience and understanding throughout the warranty approval process. We know it was a longer journey than expected, and we're grateful you stuck with us as we worked with the manufacturer to get everything resolved. Your support and positive feedback mean a lot to our team. If you ever need anything in the future, we’re always here to help.

Pete Nuessmann

We have been Mize Guys customers since moving here to Auburn in 2022. And since day 1, our heating and cooling system has been in the capable hands of Conner Mize , our assigned technician. Conner is deeply familiar with the design, stability and health of our system. We literally sleep better at night knowing that we can depend on him for quickly addressing any issues that arise with our system. Needless to say, living here in Auburn, where temperatures are extreme during both summer and winter, dependable indoor climate control is critical to say the least.
Always on time, courteous and confident, Conner is a delight to be around. This positive outlook seems to be characteristic of the entire Mize Guys staff. Scheduling appointments, discussing billing is always easy and pleasant. We fully trust this company with the overall health and maintenance of our homes HVAC. We would highly recommend them to anyone.
