After having not good experiences with two local HVAC companies, I have been very impressed with the service and knowledge of the Mitsubishi Split units at Thermodynamix.

Leo, and his team were patient, thorough, and neat during the repair/service to our mini splits. Clean slip resistant tarps were laid throughout the house. Geraldo, popped in several times throughout the service/repair to provide the team with support, and keep me abreast of the diagnostics, process, and costs.
