Service and Professionalism
The reviews indicate that the company's professionalism and service varied greatly. One reviewer, Mario Trejos, had a terrible experience with Keystone Mechanical, describing the company as "unprofessional", "not punctual", and "dishonest". He was extremely disappointed and would not recommend the company to anyone.
On the other hand, two reviewers, Nick Pedro and Emily Mirkwood, had very positive experiences with the company. Nick described the company as "professional" and "reasonably priced", and praised the technicians who attended to his furnace emergency on New Year's Eve. Emily also had a positive experience, recommending the company and praising the technician who installed her central air conditioner as "extremely knowledgeable and friendly".
