Service Experts Heating & Air Conditioning

DO NOT USE! I have a rental property in Akron. Dispatch quoted an $ 84 service charge, waived if a repair was done. Then the tech called me to schedule and we again discussed the $ 84 service charge. Turns out the $ 84 is just for the guy to show up. There is another $ 86 diagnostic fee on top of that!
He diagnosed that the flame sensor is bad, and quoted $ 429 to replace it (this is a $ 13 part that takes 5 minutes to remove/​put back). When I said no, he said he could clean the old part for $ 229. I had a another company out a few months ago and they charged me $ 27 to clean the sensor, plus their service charge. So $ 229 is outrageous and $ 429 is highway robbery.
I had my regular maintenance guy to the house a few days later, and he said the sensor just needed to be cleaned, but not replaced. He did find that the clamp holding the sensor was not holding the sensor tight anymore, so I ended up replacing the $ 13 part (the clamp & sensor is one part). He charged me $ 50 bucks, including the part.
Service Experts cost me $ 170. I was willing to pay the $ 84 service fee, but it should have been made VERY CLEAR that, regardless of whether I chose to do the repair or not, there would be an ADDITIONAL diagnostic fee.
