HVAC reviews in Windsor, Ontario

Great, fast reliable service!! The best of the best in the city! John and Nathaniel did a great job replacing our compressor, and got us running quickly again! Thanks to the whome team!

They provided us with the best prices in the city, adjusting the equipment to fit the needs of our house. The estimates were clearly documented, and they scheduled an appointment within the same week. The explanations were very detailed and honest.
Thank you for the great service!

Rating: 5 Stars
The technician came after hours, which I really appreciated. He thoroughly checked the boiler and went above and beyond what I initially asked for. The quality of his work was excellent, and I’m very satisfied with the results. Highly recommend!

Gas was shut off by Enbridge due to leak. Nathaniel was great in getting the repair done. Really nice people.

Just a super company to have working for us … everytime we have a problem they are right there with a smile and of course there expertise… great company , great people .

Service was excellent. Worked steadily and neatly. Cleaned up after service. Service people were polite and clean in appearance.

Thank you for another professional install.
Much appreciated

I like to support or Canadian companies and products

I found the technicians at Langemann Heating and Coolin to be pleasant, competent, and hard working. I am very pleased with the job they've done.

John is very competent and polite. This is our second call with them. And very happy.

Quality service done in a timely manner. I believe Langemann to be a name of trust.

Was a great experience dealing with Ryan and his team. They were quick to arrive and diagnose the problem. We purchased a new furnace and they did a great job with the installation. Everyone we dealt with was very knowledgeable and professional. A great experience, would definitely recommend them!

Excellent customer service! The water heater serving mine and my tenant upstairs broke. A new one was installed, but it just wouldn't stay lit. After replacing several parts and trying to diagnose the issue, it remained unresolved. Ryan called me, as he had seen my number come up on the call display all week and he personally came out to look at it. He arranged for a new water heater and came back that afternoon to install. The install was challenging, but Ryan, Nate and Mitchell made sure everything was perfect. They even relocated the unit so that it would run better. They did an amazing job. Thank you to the entire Langemann team: from the friendly and helpful office staff to incredible technicians and installers: Harvinder, Nate, John and Mitchell, and lastly to Ryan, whose commitment to customers is legendary! Would definitely recommend Langemann Heating and Cooling.

I called about a broken hot water tank on Tuesday, and by noon Wednesday, it was replaced. They were quick and efficient and didn’t leave a single scrap of paper behind. So impressed with the efficiency and professionalism of the entire experience. From the initial call w Amber, to the service call with Ryan, pure excellence!
Thank you so much!!

John, the technician who came for the service call was professional and knowledgeable. He diagnosed the problem quickly and provided clear options, and recommendations. His expertise was helpful in making an informed decision. It was appreciated. Thank you.

Excellent service all around. Ryan came in and took his time doing his assessment of our furnace and the vents in the house. He was extremely knowledgeable and explained what was needed very well. Once we received our quote and sent in the deposit, we were booked in quickly for first thing the next morning, since we were already without heat for almost 2 days at that point. The team took their time and made sure that everything was perfect, up to code, and even made sure that due to the area we live in, they created a base for the furnace in case of flooding. We are very happy with the services we received with Langemann and will be using them again in the future, and recommending them to others.

I’m really impressed with the work Langemann's did for me in my clients crawlspace. They were professional, on time, and explained everything clearly. They left the space clean and made sure the job was done right. I highly recommend them for any HVAC work, especially in hard-to-reach areas like crawlspaces!
These are my "go-to guys", and I recommend you make them your "go to guys" as well.

Nate did a wonderful job of repairing my air conditioner. He was very knowledgeable about all the places where a leak could be. He was also transparent in proving to me what the costs were.

Great company . Easy to work with . Fixed water heater tank (multiple companies said they couldn’t do it)

Our team was amazing, very knowledgeable, thorough, honest and completed the work well. They were quick to get out, order parts and complete the work! Would recommend!

Nathaniel very friendly, very knowledgable, explained every single thing that he did, The industry needs more people like Nathaniel. We are very happy that we chose Langemann Heating & Cooling
Thankyou
