HMS Cooling, Heating, and Plumbing

They installed a unit a little over 2 years ago, shortly after, our ceiling collapsed because of a faulty cut off switch, they came out and fixed the ceiling and the switch.
They came out June 2nd at a cost of $140 and they are supposed to thoroughly clean and service the unit, on July 29th less than 2 months since the service the unit malfunctioned, with the same problem as before, this time the cutoff switch worked, and shut down the unit, we called them and their answering service and were told we would have to wait until the 1st of August for repairs.

    We had to call another provider to come fix the unit, when they came out, they said that the units P-Trap needed cleaned out, and it should be done once a year on our type of unit. and that is what we paid this company to do and apparently, they charged us $140 for nothing. also, we had to pay $299 out of pocket to another company to thoroughly clean the unit, since this company did not.
   I have requested a refund for the $140 service call that did not happen and the $299 because they did not do a proper service call on June 2nd.

To this point all they have done is cancel our labor warranty and are refusing to take responsibility and are not paying the $439 out of pocket expense they owe. my experience with this company is that they do not honor their Labor warranty, they did not do a proper service call in June and will leave you hanging with out-of-pocket expenses instead of honoring their work.
