We have a semi-annual service contract with them, so when we had an issue with our AC, we expected prompt service – and they delivered! Always professional and courteous, with good service. Highly recommend.

We needed chimney, hot water tank, furnace, humidifier and central air. Lindemann was able to promptly provide service for everything we needed, and we were very happy with everything once all of the work was completed!

Thomas K. is great. Has serviced my furnace and installed a new water heater. Today he serviced my AC as part of my maintenance plan. Here are before and after pictures. Will always ask for Thomas and use Lindemann in the future.

Great company our guy explained everything clearly and gave great service.

The men that serviced our fireplace as well as our AC units were very professional, friendly and polite, highly recommend!

Great work has been done. I recommend Lindemann for chimney and furnace repair.I am so happy with their work that I will have my air-condition checked this month, May 30th by their expert service man.
