“Dear Mr. Mills,
I have been a customer, almost twenty years, since 2002, and I have never had reason to complain about Mills Air.
After I purchased my home, in 2002, I had a new Trane A/C installed with a ten-year warranty. Well, as with all things mechanical the Trane system needed to be replaced this year.
The technician, Travis Passmore, suggested I speak with Steve Willis. After doing just that I decided to have a new Carrier system installed on April 1, 2021.
I am writing to thank all the people involved:
# The technician, TRAVIS PASSMORE, who suggested I speak with Steve Willis.
# STEVE WILLIS, who suggested the Carrier System.
# And the installers, NICK BRASCH and CORY THOMAS, who installed the new system very fast as I was without A/C for a few days while I decided what to buy.
I look forward to another twenty years of great service. Finally, I want to thank you, LEON MILLS, for employing such great people.”

“To Mike, the service manager: Valintine – serviced two homes for me today. He treated me and my sister-in-law like “family” and that’s my highest comment.
I expect great tech skills like all your other techs. BUT… His customer service skills was fantastic. He made a 72 single woman comfortable, explained everything without talking down to her. Then he then took extra time on my PM to get my condensate drain running the way “he wanted it”. He flushed it out 3 times the make sure it running clear correctly without debris. I can’t say enough about the quality of job and experience we received. Great addition to your staff, and I’ll ask for him by name next time.”

“Ryan L recently performed a coil replacement on a Lennox air handler. Ryan is qualified and a dedicated professional. He makes Mills Air a valued business. He actually provided emergency repairs on a neighbor who I recommended call Mills Air within the last month. Another neighbor will also be calling your company for service. You can thank Ryan L for this.”

“I called Mills air because my A/c stopped working. Sean showed up to diagnose the problem. I was very impressed with Sean’s professionalism, his caring nature, and understanding of the problem. It is clear that Sean wanted me to understand what he explained. I really appreciate that.”

Lovetta Kroma

“The team at Mills Air was wonderful. Air went out at 8:00 pm and by 8 am the office team had already called and Josh the service tech came and fixed the unit in a flash! Had the capacitor with him and I was feeling the cool breeze in minutes! Thanks so much for the efficient service, response team and economically priced repair!! Great Company!”

Donna Ginther

“I heard my friend Russ Rollins on Real Radio 104.1 FM recommended Mills Air on air. I know Russ doesn’t endorse businesses on air unless he’s truly had a good experience with said company. I scheduled an appointment Thursday May 14th around 10 am, and Dan was at my house Friday morning the 15th at 8am. It was kind of surreal because Carlos Navarro(Real Radio) was bragging about how impressed he was with Mills Air around the same time that Dan was at my home. I was not able to be there but my wife was, and said Dan was courtesy, and professional. We had scheduled a preventative maintenance checkup and Dan informed my wife exactly what he was going to do and would let her know if he found anything that might need attention. Dan then informed her that he would start outside and when he needed to come inside he would be wearing a mask, shoe booties, and gloves to perform his work indoors. Dan had also called me at 7:45 to let me know he would be arriving at my home at 8am. I told him I wasn’t there but to please call me if there were any issues. Dan followed up with me and said everything looked good. I later called Mills Air to let them know that my wife and I were impressed with Dan’s professionalism and good nature. It was Mike that I spoke with and he thanked me for letting him know and that Dan gets frequent calls about the jobs he does well. I’ve honestly only taken the time to write a review like this 1 other time in my life. Thank you Mike, and thank you Dan, for doing a job well done. I will go nowhere else but Mills Air in the future for my AC.”

Jerry Johnson

“I highly recommend Mills Air. The company is responsive and timely. Service technician Dan Arnold arrived on time, was courteous, knowledgeable, thorough and professional!”

Cathy Salerno Wallin

“Your serviceman Dan came to my house today to inspect and service my HVAC unit. He was very helpful, friendly and careful to provide social distancing. He protected himself with facemask, gloves and foot protection to prevent spreading Covid 19 virus. he was very informative and frank about the state of my HVAC units. I would readily recommend him to others. I wish all servicemen were like him. Thanks for sending your best”

Dave Plavcan

“During a recent maintenance visit one of my units was found to be low on coolant. It was recommended that I have a leak check done. Sean was the technician that responded for the leak check. Sean was very informative. He explained everything he was doing with great detail. He found the problem and ordered the part the indoor coil Today Sean returned to my home and installed the new coil. During the process Sean encountered a problem and immediately looked for the solution until it was fixed. He didn’t leave the work incomplete even though this additional work set him back on his later appointments. I really appreciate Sean’s knowledge and dedication to his work.”

Laly Serraty

“Jay did a great job and his customer service was good. He showed is what needed to be done to our A/C and explained it to us… We have other service people come to do our A/C over the years and did not do a good job. Jay is a keeper…..I have told some friends about the service already….”

Andrea F

“Dan did a great job! He was very thorough in determining the problem with our a/c unit. He was very patient and took the time to explain what he was doing and showed me parts that needed replaced or needed attention. He gave me great suggestions on how to fix things without being a pushy salesperson. Great experience. Would highly recommend.”

Stephany Helenthal

“Great service, quick repairs and fair prices. That’s what’s kept me a Mills Air customer for the last 15 years.”

Matt Pollitt

“2nd time I have used Mills Air for my AC needs and again I am so totally satisfied with the service and the professionalism of the tech, Hunter. He immediately identified what was wrong, completed the diagnostic check of my AC system and provided me with detailed information on the repair. Hunter is a credit to the profession and most definitely to Mills Air. Without reservation, I highly recommend them for all your AC needs. BTW, I heard about Mills Air on the Real Radio 104.1 on the Jim Colbert Show. Your advertising pays. Thank you again for a great job.”

Joseph Fuller

“Just wanted to say how pleased we are with our recent service, your company and our technician (Jay). He was outstanding in every way – friendly, professional and extremely thorough. Very happy with all aspects of our service and especially with the great job Jay did! Thanks!”

Denny Obermiller

“Every once in awhile people slip through the cracks. Unfortunately for both Mills Air & I that’s what happened to them. I won’t go into the details, but one of their techs showed up late, was very unprofessional and ended up doing more damage than good to my system. It turned out to be quite a costly error but Mills stepped up and took care of the problem very promptly and efficiently. Manager Mike was the ultimate professional and it was one of the best customer service interactions I have ever experienced. They sent their lead tech out the same day that I called and he quickly identified the problem and fixed it. Sadly, the fix came too late and the damage was already done. This was going to result in a significant cost to either me or Mills Air. Mills stepped up and gave us a very fair reimbursement check and relieved us of a significant financial burden right before Christmas. I don’t leave reviews as a rule, but due to the nature and severity of this issue I knew that I would be leaving one either way, good or bad. It is very important in my eyes, that companies still put the customer first and stand behind their product. I am very pleased to say that Mills went above and beyond and will have our business for years to come. As a side note, I am also pleased to say that between the time of the original Tech coming out and screwing everything up and the time that we recognized it, he had been identified as a bad egg and was no longer with the company.”

Chris S. Tavares

“Mills air called ahead to confirm appt. Sean, the service person was prompt. He took the time to review the issue I had with the system and quickly analyzed the problem. He explained in detail the mechanical issue and the need for a replacement part. He reported the issue to his office and I was surprised to find out that they could come back with the necessary part the same. All was installed quickly and my system is back in order. Sean was very professional and provided excellent service. I have been utilizing Mills Air for over 10 years. Their service personnel and customer experiences are great.”

James Rychlicki

“Lis and Ryan went above and beyond to resolve our AC issues. Ryan (our technician) spent almost four hours trouble shooting our multi zone carrier unit to ensure proper diagnosis. He took the time to explain the process to me and answered all of my questions. Highly recommend and will continue to use them in the future.”

Hillary Spillman

“I had to have a blower motor replaced and used Mills Air. The tech was Ryan and he was outstanding. Very knowledgeable, answered all of my questions and completed the work very quickly. As luck would have it, shortly after, my compressor quit working and Ryan was nice enough to spend time texting things to check to try and get me up and running asap. Outstanding customer service! Thank you Ryan and Thank you Mills Air! And thank you Monsters in the Morning 104.1 for referring them!”

Rick Schoppe

“Jay came out to do routine tuneup on our system. From the moment he stepped in the house he was friendly and courteous. Jay went through what he was doing and what problems could occur. He suggested a preventative system to help keep our unit running well along with keeping the over all air quality in our home healthy for me and my family. Jay will alway welcome in my home. Thank you Mills Air for having friendly, knowledgeable, and courteous employees.”

Denise Rossi

“Jay has been our service technician since 2015. His customer service is superb. He is always helpful, knowledgeable and very courteous. I cannot say enough good things about Jay and Mills Air. Would recommend them to anyone looking for a company to install or maintain their HVAC units. Thank you for such great service!!!!”

Debra Koppenaal

“My air conditioning always failed at not regular working hours. Called them at 6. Friendly customer service and fast. Told me that from 8 to 10 they will be at my house and at 830 they arrived. Fixed it in less than 30 minutes. My air conditioning is alive again. Thank you for the excellent and fast service.”

Lizbeth Santana

“Jay was a tremendous help in getting our unit cleaned up and running. Showed me the issues first hand, demonstrated great knowledge of how to prevent these kinds of things in the future and how to prolong the life of the unit.”

Robert Findlay

“I was very upset, our air was off for 24 hours. We have 3 dogs, and had to take 2 cold showers. It was not a good day or night. When Jason showed up to my house, he was pleasant, understanding, and listened to me complain. He immediately knew what the problem was and got right to it. Jason made me feel like I was important, that he knew what we were feeling. Jason even took the time to explain the problem and gave me examples on what we could do in the future. I can’t say how much Jason made our house feel whole again. We had cold air and it felt amazing. Thank you so much sir we appreciate everything you did!”

Melissa S

“We purchased a newly constructed home & have had contractors in & out and Mills people always professional & seem to care which has not been the case with other companies. Leon A at Mills Air took the time to explain the issue, was very informative & professional. Lisa who answers the phones is always helpful & patient. Jason & Ryan have also been very thorough taking the time to cross off any potential problems. They are usually pretty prompt when coming out during weekends & off hours.”

Danielle N

“Professional, courteous demeanor, Sean the Technician was a pleasure to deal with. He went beyond the solution to make sure I understood the repair and it’s implications. I would recommend Mills Air to anyone needing air conditioning services.”

Connie Welch

“Jay came to do the semi-annual inspection of my air conditioning unit. While he was checking on the unit he found a lot of mold on the inside front cover. He recommended getting the ultraviolet system which is something I had been considering anyway. He was able to install it the same day. Jay was courteous and very efficient. I have been using Mills Air since 2014 and am very happy with their service.”

Maria Wiegelmann

“This e-mail is to comment about the dedication and professionalism Eric and Alex displayed when they installed my air condition unit on 27 Sep 2019. There were a few obstacles with the drain line, but Eric had all the solutions to the problems to get the job completed. The clean up job was very neatly done and I will definitely recommend your company (especially Eric and Alex) to my friends and neighbors. By the way, I would like to add, I am freezing. Have a good day.”

Wes Henry

“Thank you Hunter for getting my AC working again. Hunter was kind, professional & explained everything to me. Hunter was awesome.”

Roberta Player

“Mills Air came through for us again! Joe, Josh, & Ben all worked hard to fix our AC unit quickly during this hot summer. We greatly appreciated it their quick response, knowledge, & professionalism.”

Erika Dold

“We lost our a/c about 7:45 this evening (just before fireworks) and I called Mills to report. The on-call service reported that someone would get back with me shortly. In less than 5 minutes Josh C. called and said he would be able to be here within an hour. He was here in less than 40 minutes. He was knowledgeable and informative about the problem. THANK YOU to Josh for getting us back up and running. You were a pleasure to work with.”

Richard Ferney

“I have an AC company but they let me down tonight wanting $200 an hour for after 5:00. Mills Air came to the rescue! Sean was here well before the promised time and fixed everything for a fraction of the cost. You have a new loyal customer Mills Air! Thank you Jim Colbert Show for running the Ad.”

Theresa Alford

“Dear Mr. Willis,

A note of appreciation: Your team installed a new a/c unit on April 13. I wish to thank them (Eric and Alex), your service technician (Julio) and YOU for a transaction that was handled in a very professional manner.

Julio took the time to explain the problems, you took the time to help sort through the options and the installation team were fast and friendly. The system passed inspection easily and is working well.

Again, thank you. I like dealing with your company.”


Paul Bergman

“I want to take this opportunity to commend two (2) of your employees, Chris Hdnriquez and Jonathan Roebuck, for providing outstanding service and demonstrating a high level of technical expertise; pride in their workmanship; maintaining high standards; dedication to mission (task) completion versus working to the clock; and total professionalism. Based on my observation, Chris and Jonathan work as a team ensuring the task is done correctly the first time and set the standard for others to emulate. Initially, I was convinced that the HVAC System installed in our home was designed for a torture chamber to destroy mankind with various damper mechanisms and possessed by the devil. After numbers visits by Mills Air technicians, Chris and Jonathan were given the mission to fix Steele’s HVAC System. As of date, they have been successful in resolving most of the major issues. Both individuals possess the ability to handle the complex issues as routine and accept the issues as challenges to solve. Chris and Jonathan are valuable assets to you and your company standards and their professionalism greatly reflects on your company standards and their pride as being Mills Air employees. They are the best of the best and reflect highly on your company and your leadership.”

Very Respectfully,

Edgar (Ed) W. Steele

“So far, my new system is working properly and cooling nicely. I will not hesitate to recommend Mills Air, and particularly this team of technicians; they represented your company well. Even my neighbors were impressed! Kudos to Ryan and Nick!”

Linda Bess

“I just wanted to write you and the crew a note letting you know how pleased I am with my new system and the professionalism, quality of work and courteous service Mills Air provided to me.

I appreciate that you did not try to up sell me a system that I did not need. The 13 Seer / 2 Ton unit is perfect. I keep it set at 79 and the house is quite comfortable. Your installation team of Oscar & Iswbar were a pleasure to work with (timely, friendly and tidy), when they left you did not even know they had been here. Today they completed the duct sealing work with the same quality of service.

I have already bragged on Mills Air to several of my friends.”

Pam Blanchard

“Within 2 hours of the call Raymond, one of your HVAC techs, showed up and was friendly, fixed the issue quickly AND properly, and was on his way within the hour. Probably the BEST experience I’ve had with HVAC issues in my time here in Florida. Thanks again Mills Air, I appreciate your fantastic employees and quick service!”

“Our experience with Mills Air was outstanding, beginning with your Comfort Expert Tom who spec’d our new unit, answering all of our questions and making knowledgeable recommendations to ensure that we received value for every dollar spent, to your technicians, Nick and Ryan, two outstanding performers who did an excellent job installing our new system. We couldn’t be more pleased and have already recommended Mills Air to our neighbors.”

“Mills Air did a great job!”

Tom S., Orlando, FL

“On June 12th I called to get someone to come to my house and give me an estimate for the replacement of my home A/C heat pump and I was told that Steve Willis would be here between 10 and 11 AM on Friday. Well Steve was here in that time frame and did a very good job answering my questions and explaining what the best way to go was and all the options available to me. As soon as he left I knew I was going to do business with your company. I called the other companies that were scheduled to come out and cancelled those appointments. I called Steve to come back so I could sign the contract. That’s not all, the next day Saturday the 13th Nick and Ryan were here at the time I was told they would be and did a great job getting this new unit installed and working in a timely manner. If this equipment performs as well as your company has so far I will be a very happy customer”

Tom Naughton

“I have been extremely happy with the unit. I found Mills Air to be friendly and trustworthy. I am very happy with Mills Air, Inc.”
