HVAC reviews across the US

Called at 8:00 at night they called me back fixed my air conditioning by 9:00 the next morning. It was hot and humid out thanks to Ziegelbaurs Fast response and Action I didn't have to suffer from Hot Humid Heat. I Highly recommend them. Very professional and polite Great Service. 👍

Worst customer service I have EVER had!! They cancelled on me 3 Times!!! Twice I called to find out if anyone was coming, and was told "no, they are caught up on another job". No apologies for cancelling on me, when I rearranged my work schedule to accommodate them!! They were reccomend to me by a satisfied customer. However, I will NEVER reccomend them to anyone else. I did give them the benefit of the doubt and took off a day of work to still use their services and Scott was Great, too bad I can't say the same for their customer service!!

Cathy is a blight on what may otherwise be a good company. She never answers the phone - I called from outside their office more than once since she wouldn’t answer, she lets it go to voicemail, I go in the office and she’s sitting at her desk playing on her cell phone. Doesn’t return phone calls and doesn’t follow up when she says she will. She never has any clue as to what’s going on. The actual guys doing the work were good guys. They left the job half done at 3p sharp though - so don’t expect any long days. Funny how she gave herself a 5 star review. The last thing she said to me was ‘welcome to fond du lac’ that this is how it is here. As if she was proud of her horrid service. I wish you could give negative stars.

Zero customer service. Doesn't return calls or perform follow through. Whoever runs their office plays "Queen of the Hill" and only responds when she feels like it. It's also really funny that she gave her own company 5 stars, ethics anyone?

I called for estimate and they wanted $85 to diagnose problem, and wouldn't give me hourly rate at first, and then after I pushed the issue a little more, she finally told me they bill out at $135/hr..... No Thanks!

Wesley has done both our A/C unit and our furnace installations and their customer service and professionalism is top-notch! We will be Wesley customers for many years to come! Thank you!

Welsey Heating & Cooling are always prompt and gave us same day service. Our furnace need to be replaced and they gave us many options on models and payment options. They are all friendly while maintaining their professionalism. Never been disappointed with them yet.

Our AC went out, and my dad called them as he's used them before. They told him the entire unit needed to be replaced and it would cost over $3,000. They set a come-and-fix-it date two weeks out and they were told the job needs to take place after 3:30pm since no one is home before then.
The day before they were to come, a lady called and told my dad they would be here in the morning. She refused to work with him on the time.
So my dad called another company, who promptly came out for the diagnostic and wound up fixing the whole unit. It was simply a wire that needed to be replaced. Cost a couple hundred! Not $3k!
We won't be using this service again.

The crew showed up on time, removed old furnace, and wasted no time installing new furnace and AC. Wesley gave me the best price out of 3 estimates I had done. Technicians were friendly and knowledgeable. I could not be happier.
Thank you, Mark

Very satisfied with replacement of our furnace

Central air stopped working. It was 87 degrees in house. Called and very knowledgeable guy came out and fixed it that same morning. So impressed. Thank you so much. 5 stars for sure.

Wesley came immediately within a half an hour of my call. They did a new install a few days later. They were quick, polite and efficient. I recommend Wesley all the way!

After my furnace went out, they went above and beyond to get to me fast. With the temperature dropping so fast, they offered portable heaters to help keep my home warm until the job was completed. Mike was the tech that came to my home, ahead of schedule, and got my furnace fixed in no time.
I can't thank them enough for being so kind to answer all my questions and get to me so fast!

From request for a service call, through diagnostic visit, providing an estimate of time and cost, through scheduling and final installation, I was kept fully informed, had my questions answered fully and with the authority of one who is intimately familiar with the product and process. The price was fair, the work was done more rapidly than I expected and clean up was effected beyond my expectations. I was pleased with the people who came, the office personnel who handled my calls and contacts and the work that was performed. The new boiler has been working beautifully ever since installation.

I had my furnace serviced by Mike Madison from AirTech today. Mike is very polite and professional. He completed my service in a reasonable amount of time. Fees were very reasonable.
Thank you

Had to have our furnace replaced after 30 years. Called Air Tech. They replaced it. Could not of asked for a nicer group of people to work with. From the office staff in both Ripon and Fond du Lac. To the technicians who came out first and tried to fix the old furnace. To technicians who installed the new furnace. They were all Rock Stars. True customer service is alive and well at Air Tech Heating. They knocked it out of the park!!! Highly recommend them.

There were many vendors in the Ripon Area to service the HVAC needs that I had for the 96 year old home I purchased in 2009. I was looking to replace an oil fed radiator heating system and discuss with the local vendors solutions on how to heat/cool a 2800 sq.ft house.

AirTech Heating proposed the best solution and most cost-effective at the time (and they were not in Ripon but Fond du Lac). They are now a great resource to have locally 10 years later. Usually their maintance plan covers service to your furnance and AC units; however, in my situation, I have 2 furnaces (one in the basement supplying the first floor, and one in the attic supplying the second floor) and 2 AC units supplying each floor as well.

The furnace in the basement is 95% efficient, while the attic one is 98% efficient. The furnace blower in the basement has been changed out twice in 10 years, and only minor maintance to the attic furnace. This year was the first year in 10 years that I needed a tech out to add some pounds of Puron into my AC Units. Otherwise, I have been very happy with AirTech Heating and the "Bryant" Brand that is supplying heat and AC for our home. I would highly recommend this company and the products they provide.

On a side note, the techs initially worked with my back in 2009-10 to also install all new duct work for the supply of the forced air units and the returns too.

I'm super glad I called! Mike came out & was super kind. Explained alot of things to me as I was a first time central air owner. Cleaned my absolute mess of an external unit really well. Will definitely keep their # for service & emergencies. Inspected/cleaned my heating unit as well, and cleaned up after himself. I am very grateful for his time & knowledge.

I initially contacted the after hours service on Christmas Eve 2025. My phone call was returned a short time later on the same day. I was located in Texas at the time. The staff was professional and provided expert advice related to the house located in WI and the upcoming weather, as the residence was not occupied at the time. They outlined a plan which was centered around common sense and the best bang for the dollar in scheduling a technician to respond and troubleshoot the heat related issue. Air Tech was recommended to me as a trustworthy and skilled HVAC business and I found this to be accurate and true.

We had a boiler repair completed today. 1.19.26. Noticed an issue over the weekend, submitted a request for service and was called Monday morning. Was lucky to have a technician available that morning for repair. Excellent friendly service. Technician explained the issue every step of the way and provided education on the boiler and what to expect for normal service and use. Would highly recommend. Thank you for the quick response and repair.

The font desk staff is very friendly and helpful. The techs that come out are always, polite and friendly along with being efficient. The price always seems fair for a job well done!
