Save your time and money. They fixed nothing, but charged me $99 for a dispatch fee and then $303 as a “diagnostic” fee. Basically, they called the company that made the machine and pointed out some things that need to be fixed. Then ultimately said that a new entire heating system is the solution for the price of $15,000. Tried to make it sound great by offering payment plans and credit. Got a new HVAC specialist who was able to repair what they could not and just looked at. Companies like these are tricky because they charge you for doing very little, but really want the big bucks of a new system.
