I look at reviews and sometimes think they are fake or written by family members. This is not a fake review.
This contractor is dishonest and should not be used.
My tenant called me at 6PM on a Friday night and told me the furnace stopped working. I called Master Mechanical and they told me someone could be out in 2 hours. The charge would be $150 and I would be charged from the time the tech left the previous job to the time he finished my job. The tech called me at 8:12PM and told me he was leaving to my house. He completed his diagnoses at my house and left for another job at 9:03PM. This is less than one hour and I was charged $225. The supervisor told me I was charged extra for the tech to go home. However, the tech told me he was leaving for another job. The tech did not go home after my job, he went to another job. So the supervisor is double charging the tech travel time to me and the other job.Next the tech proceeded to tell me by blower motor was beyond repair and I had to get a new system (thousands of dollars). There was nothing that could be done until Monday because they were closed on Saturday and Sunday. The tech said his boss would call me first thing Monday morning. I had to tell my tenant to move out of the house until the furnace could be replaced. His boss never called me until Wed night ( 5 days later). I am glad I did not wait for them to fix my system.
I drove 4 hours round trip to check out the furnace myself the next day. I checked the blower motor and to my surprise there was nothing wrong with it so I called another contractor to diagnose the problem. In 15 minutes the other contractor found the problem and proceeded to fix it. The other contractor said it would be a good 5 years before the furnace needed replacement. I called my tenant and told her to move back into the home. Thanks to the other contractor my tenant only stayed away from the rental for 1 day instead of several days and I saved thousands of dollars.
I spoke to my neighbor about my furnace and he told me his blower went out about 3 years ago and he had to have his entire furnace replaced. I asked my neighbor "who told you your blower motor went out and the system needed to be replaced?". Surprise, surprise, Master mechanical.

They charged me for drive time TO AND FROM the appt. They also didn't quite have enough freon to fill my very average size AC system so they charged me for another appt, once again the drive time TO AND FROM the appt. This means they are essentially charging double time to their customers if they are going from appt to appt!! This didn't come out until I got charged $600 for a simple freon fill up. I've had many of these appointments before in my various rental houses and I've never been charged $600 for filling freon. When I told management (John) my camera saw their tech was only on site for an hour, he pulled the driving records and showed me they charge the drive time both ways too. In addition, if the tech doesn't have enough freon, any other AC company in the world would send the tech out again for free due to the embarrassment of the tech not having the most basic material that is so common to need when ACs go out. The technician was great, but the billing practices and management have backwards and corrupt views. How is it my fault you needed another trip because your tech ran out of freon? Why am I responsible to pay drive time between your appointments both ways, when your tech could be coming from California for all I know??
