Extremely dissatisfied with the service by this company. They serviced my home heating boiler in March 2019. The service man parked a block away from my home - in paid parking. Parking is free in my parking lot that is 30 feet away from the heater. I was then billed for the paid parking charges. The heating boiler was not completely serviced. The serviceman indicated it needed a better ph in the water. Also, the condensate filter (see picture) needed changing. This was not done.
Ten days after this inspection and service, I received a bill for $398. No explanation of what was done or itemization of the charges. I called the company and complained. Only then was I sent an email with a list of what was supposed to have been done. As you can see in the picture, the condensate filter was not cleaned or serviced nor was the ph of the water serviced.
Very poor follow up by the company to make this right. My advice is to stay away from this company as there are better choices out there for sure.
