I had experience with one of them for 3 jobs and every job was not done.
1 was an electric oulet issue - the GFCI would indicate red and lock out, meaning wiring fault, the guy they sent couldnt identify the fault and took money from my mother, I later on drove to their local office and got my money back and asked them abt this job.
Their electric repair only covers changing wall sockets and plates (anyone can do that)
the next was an AC problem. the guy stuck gauges on a dirty condenser coil and adjusted the r22 charge, - cue next day, no worky.
comes back - says there is a leak in the evap and condenser, instead of supplying a whole new matched unit (which would have made sense) - they supplied an old stock r22 evap slab coil furnace and an R407 condenser unit.
if they can find its 5 cents cheaper to do it the wrong way - then the wrong way it will be done.
