Customer feedback highlights Dave as a technician who received commendation for resolving a caller's urgent need. Conversely, multiple reviewers recount frustration: Mike Anderson described persistent scheduling cancellations after a heat system failure, noting his maintenance inspection occurred weeks prior with no detected issues. Another reviewer, Ferney Lopez, reported ordering a replacement part that arrived incorrectly after one month, alongside an eight-hundred-fifty-dollar charge for three hours of project-based labor. A separate reviewer identified dangerous driving conduct by a company driver on snowy roadways, refusing entry to their residence. Marro761 simply referenced great technicians without elaboration.
