Bill was quick to respond to my inquiry. He scheduled a visit to assess my system and gave me a quote with a couple of options and prices. Once we decided on an option and scheduled the work, things moved quickly. Bill and Richard were friendly, prompt, and professional. I am pleased with the work to replace my furnace, AC unit, and thermostat. I am happy to recommend Thermodynamix.

Bill & Richard replaced our heating/AC unit and thermostat. They installed our unit in 1 day and did a great job, Extra kudos for leaving my house clean after they were done. They called prior to arriving and they both are very friendly and very professional. I definitely would recommend Thermodynamix hands down!
