HVAC reviews in Fond du Lac, Wisconsin

Guys were outstanding with cleaning my dryer vent. Dryer works perfectly now and they were so upfront and honestly about the whole process

Jeremy S was awesome to work with. Was very clear as to what to expect & the process. Was very knowledgeable and respectful. Jeremy kept me updated throughout the entire day about how things were going and where he was at in the cleaning stages. Was mindful and respectful of our home and our requests. All in all...extremely pleased with Jeremy, the awesome job he did and his work ethics.
Would absolutely recommend Jeremy to anyone in need of duct cleaning and would invite him into our home should future duct cleaning present itself. Thank you for a job well done!

Josiah is a very knowledgeable service professional and his staff (Jeremy at our home) did a great job. They arrived on time and set up for the job. As the process progressed we were advised what was happening. We were shown before and after pictures. Amazing! The job ended at approximately the estimated time.
Jeremy was personable, professional and thorough with his cleaning work. I highly recommend this company!!

Josiah from WI Natural Air Duct Cleaning came in & did such great quality work! The difference in my air quality was literally like night & day! You will not find a more professional business that has such a quality person as their owner|operator. I was more than pleased with the service I received and the price! He went through each room & took his time doing a great job! He explained everything to me with photos. I couldn't be more grateful and
I highly recommend!

Great experience with our air duct cleaning! Jeremy was professional, friendly, and very thorough. He explained everything clearly and did an excellent job. Highly recommend!

Josiah did a fantastic job installing my bathroom fan, and he had his work cut out for him, replacing an extremely old unit. He was very friendly, informative, and professional. Would highly recommend him.

Our experience with Wisconsin Natural Air Duct Cleaning was unbelievable! Jeremy took time to explained everything he did throughout the day and was very informative. Jeremy was punctual, professional, and treated our home as if it were his own home. Wisconsin Natural Air Duct prices were very fair and Jeremy worked very hard throughout the day. I strongly recommend Wisconsin Natural Air Duct Cleaning Service.

I bought an air purifier that said the air quality in my home was bad. So I called Josiah and he came to clean my hvac a few days later. He was very friendly and did a great job. I would highly recommend their service

He is super kind and informative . He did an awesome Job! Will be contacting him next Chimney cleaning time. Thank you Chimney Medics!

Jason has been in the business a long time and it shows. Showed up right when he said he would both times, and gave a fair an honest assessment of my fireplace/flue condition both times. Based on his professional opinion, I was able to make a decision to upgrade my faulty system, which turned out to be the best way forward-

Great and honest people.

Amazing company. Very professional. Highly recommend

My air conditioner wasn't working. I called Randy at 7:15 and by 8:30 someone was here to help get my air working again!

Thank you Shane for coming out and fixing our AC on the hottest day of the year!

You want excellent service you call Hilbert Heating and Cooling in Fond du Lac.
Wonderful people! Very responsive. I called and they were there the same day. Had to order a part. As soon as it came in they were back to replace the part.

Ryan came on a Saturday, to help with our AC. Just a great company to work with. From his dad to him always great service.

Ryan does the maintenance on our business’s ice machine and has always done a great job in a timely-manner. 10/10 recommend

They wanted to change a bunch of items for installing a new furnace including return air and overcomplicated the process for really no reason and made it seem like a big deal to install it. (Mentioned he would have to get in contact with an engineer even). I'm an electrician and I'm no dummy so I went with another reputable contractor and they got the job done with a nice 2 stage furnace thats not only a smaller unit but also more fit for the house. Return air was a simple solution of adding a vent to the main area of the house through a wall for flow. Worked wonderfully. Price was very reasonable with my other company. I won't return here or recommend them to future home buyers for the hassle. Not pleased in anyway. The only reason I gave 2 stars instead of one was because he was at least on time and spoke in a professional manner.

They did a great job installing a heater and A/C unit in our building. Very professional and forward thinking.

I used Fondy Heating on a recent basement remodel. The customer service and pricing was great. Explained the best solution for my needs and serviced my existing system (that they did not install) while they were there.
Thank you!

Was a little nervous reading some of these reviews prior, but Caldera did an excellent job fixing our AC and replacing our capacitor! We have HSA home warranty. Luis and Omar were very friendly and respectful. They even arrived earlier than they planned to on the day of when I called them to let them know our condo office and maintenance personnel would be out of office if they came later in the day. They fixed the issue quickly and also took out our old yucky filter for us and told us exactly where to get a replacement filter and what size. Really appreciated their responsiveness, timeliness, and courtesy!
