Unfortunately I had to give them one star! They certainly do not deserve it! Bill Worlock came out to repair my system. They said it needed maintenance and to replace a basic part. After they were done(and $3400), it still didn't work. They then said I needed new thermostats at $189 each ($60 at the local hardware store). The one unit still didn't work. Then they said I needed a new compressor for an additional $1900. At that point I told them to leave and called a reputable HVAC company. The new contractor came out and fixed Bill Worlock's mistakes (wrong parts etc.) and advised me that if they had worked on it from the beginning it would have been just under $400.
Additionally, Bill advised me that his "sheet metal fabrication plant" would make me two new condensate pans for an additional $1100. Turns out the pans are $20 each at the local HVAC supplier.
Bill Worlock is very unprofessional, dishonest and incompetent. I guess this was a lesson learned for me!
