    Danielle was a great help getting my service call scheduled quickly and was very nice to work with. Technician Jimmy was very knowledgeable and did a great job fixing my furnace. Highly recommend this company!

    After my heat breaking mid-winter on a 15° day, and not finding any company able to help for 48 hours (and HUNDREDS of dollars in charges for a weekend visit) Thermodynamix jumped in and sent someone over within 30 mins - on a Sunday. Chris was super knowledgeable and even taught me about the older furnace I had, and why it wasn’t working. I was so pleased with the service, I immediately recommended my uncle to call them for help when his furnace broke not even 24 hrs after. We are both SO happy to have heat - and a fast responding, knowledgeable company to support our whole family. I’ve already recommended them to my parents and other friends.

    Spring 2025 A/C Checkup. Chris came to check our 2 A/C systems Thermodynamix previously installed. Chris was very courteous and arrived timely for the appointment. He examined our 2 A/C systems very thoroughly; made sure our filters and coils were clean and ready for the summer season. Well done, a satisfied customer!

    The technician, Kevin, arrived right on time and was friendly and courteous. He got straight to work and quickly and efficiently serviced my whole system. He also answered several questions I had and gave me some good advice. Excellent service! Thank you.
