SOS Heating and Cooling, Sherman, did an awesome job. Following an appt with Airtron, resulting from a contract with Reliant, the repair would have been over $1850, $850 out of my pocket for a new circuit board, in addition to another suggestion which would have resulted in an additional $495.00 more, I requested they go no further and I would contact my home warranty policy instead. SOS was contacted by Liberty Home the next day. Sherman called to confirm the appointment, was on time and took less than 15 minutes to diagnose and my AC system was working. He showed me that the electrical switch outside was turned off, obviously never turned back on by the previous Airtron Tech that had stated I needed a new circuit board. Going forward, I will be be cancelling my current AC maintenance contract with Reliant and changing to the SOS Heating & Cooling AC maintenance agreement. Thank you Sherman for excellent service...
