  This company took a $5000 deposit for a generator from my elderly mother. She has no generator and they are refusing to return her deposit. They saw an opportunity to rip off an elderly woman and they did. Scumbags. Avoid at all costs

  Called MidState when my boiler broke. Got threw to Guaranteed Service instead since they bought up MidState. They had a very professional tech (*****) out that same day and worked around my schedule. He showed me exactly what was failing and explained everything in detail as to why it needed to be replaced. That same night they had a supervisor (Al) come out to discuss options and give us some ideas on cost. We asked for a night to think about it. ** spent his time explaining options, talking to my father-in-law on the phone to explain the details, petting our cat, and generally treating us like people. He took his time with us which was really appreciated. Highly professional. Called them back the next day and scheduled an appointment that same day to sign the papers and revise the plan at 6pm. Since the job required a chimney liner install ** brought out **** to give his opinion on the plan. **** was extremely knowledgeable and said the job was well planned and ready to go. They came out the next morning at 8am to install the new boiler, thermostat, and chimney liner. Originally the liner was expected weeks later but somehow they got in there the next day. The installation crew lead by **** was awesome and polite and professional. The job was tricky but they got it done, communicated well to me and made sure everything was working before they left. Honestly the company from first call to last handshake was awesome. Really kind professionals that knew the line of work extremely well.

  They charged me $257 for 1lb of coolent and $89 for the 2nd lb and when I questioned why their price was so high they could only say that it was due to high prices everywhere. I contacted 3 other companies feeling I was ripped off and the highest quote for the same amount of coolent plus a service charge was $100 less! Their receipt is emailed without any itemization of the work that was performed which is also scetchy, when I asked to speak to the manager *****, I got the complete runaround and only after multiple calls did he finally return my call, he was rude, condescending seemed to not care less telling me I should have gone with another service. I would not recommend them to anyone and would never use their services again!
