Recommended Customer Reviews

Scheduled service for a leaking AC unit that is ruining my floors. Agreed to service between 10-1. I specifically tailored my schedule to be home between the scheduled time. I arrived at my house at 9:50. Checked my cameras to see the technician came between 9:15 and 9:30, well before the scheduled time. I called to see where he was and they said he cannot return between the time THEY had it scheduled for. I asked to speak with a manager and reschedule. They stopped answering their phones and did not call back. The manager I left a message with has not returned my calls. If you tell me when you will arrive at my home, don't show up 45 minutes early, not stay until the scheduled time, and blame it on the customer.
EDIT: I am editing this review after they attempted to "resolve" my issue and still give this business 1 Star. AFTER I left a review that negatively reflects on Master Tech, I received a call for a technician to return to my home on an agreed time. They finally showed up and claimed the issue was not an HVAC problem and to submit another service request thru my warranty company for plumbing. I did so and lo and behold, Master Tech was again contracted out for the job. I received a email saying someone would contact me shortly since I had an "emergency" request. I called to schedule an appointment, no answer. Master Tech never called me back or ever scheduled an appointment. I went online to check the service request and magically it stated that a contractor was yet to be located for my request. This is after I received a confirmation email stating Master Tech would contact me for expedited service.
This company is a joke and they DGAF until it affects their bottom line. Even then, they can't seem to get anything right. I actually had to call my warranty company to make sure to have Master Tech contracted out to my home.

Master Tech Service Corp does shoddy work and hides behind a worthless 30 day warranty. I had them (through American Home Shield Insurance) come out to fix a faulty shut off valve in my guest bathroom. Months later, unbeknownst to us , it had sprung a slow leak, slow enough that by the time it would be detected, the damage was already done to our once perfect floor. THE NEGLIGENCE WAS OBVIOUS TO THE OTHER PLUMBER WHO CAME AND REPAIRED LATER because there had been absolutely NO pipe dope or sealer put on the threads when they replaced the valve. That is BASIC plumbing and should not have been skipped over. Now we are in a position where we have to replace flooring and sub-flooring and remove the toilet to do so. I nicely requested to file a claim with their insurance and they flat out denied any responsibility. Now, I am forced to pursue this through other avenues. I've read other reviews as well and surprised they haven't been sued already. Worthless. I will not be using them or American Home Shield again ever. I suggest you steer clear of this company altogether.

This company is dishonest and unhelpful , unable to do the work but not welling to admit it. For Ac problem spending more than two months could not fix it, even not answer the phone, avoiding customer's questions during this hot summer weather in Texas.

Where do I begin? Wish I could leave no stars. Bear with me, as this review is a culmination of almost a month of rage and poor service. Our A/C had gone out (compressor was broken), and so our home warranty enlisted a technician from Master Tech to come out to our house on a Saturday in April (I believe it was around April 28).
To preface this review, I come from a family of HVAC engineers. For example, my dad used to design and install industrial HVAC systems (the giant units that go on top of industrial buildings and businesses). When I have a doubt or question about something, my family typically knows the answer. It's unfortunate that my dad no longer does that kind of work and, as such, does not have the necessary tools, or I would have had him do the repairs himself (and saved myself and my husband a lot of headaches and fluid loss).
As it was, my dad could not assist us except to give us his thoughts on what was wrong, and so we met with Rocky, the first Master Tech technician to whom we were introduced. Rocky seemed knowledgeable enough, and gave us a list of issues. One of the things my dad had said I should ask about is if we had a Freon leak. So I asked Rocky just that.
Rocky replied that he couldn't tell, because since the compressor was broken, he couldn't check the Freon levels. Rocky then said that it's quite possible we do. Later, I had my dad call Rocky and ask him (I guess in engineer-speak) what the PSI was on the meter when he was checking the compressor. Rocky said the PSI was 120. To which my dad replied, "Well then, if there is still that much pressure in there, wouldn't that rule out a Freon leak?" Rocky then backpedaled and told my dad that yes, most likely there wasn't a leak. Which completely goes against his earlier statement to me when he said "It's quite possible that you do have a Freon leak."
That was my first poor interaction with the company.
We were then left with three options given to us by Master Tech. Rocky told me that we should be hearing from the home warranty company in a couple of days in order to schedule a service.
Two days, then three, ticked by, and we still hadn't heard from the home warranty company. So I called the home warranty company. They informed me that they had yet to receive information from Master Tech regarding what was wrong, and that they would try and reach Master Tech and get back to us. Finally, after four days, the home warranty company called us and said they had finally been able to reach Master Tech and that Master Tech would be calling us to set up a time to schedule the service (we were going to have to pay a fraction of what we had thought we were going to pay, so we were happy at this point).
We waited. And waited. For FIVE more days, we waited. At this point, we'd been without A/C for two-and-a-half weeks. Did I mention yet that I am 9 months pregnant?
I called Master Tech and left voicemail after voicemail. I called them in the morning, afternoon and evening. I left my phone number, my name, my husband's phone number. I called the warranty company to ask them if they could reach out to Master Tech since Master Tech was being unresponsive.
And still no response from Master Tech. My home warranty company sent emails to them and also left them voicemails. NO RESPONSE. At this point, I was desperate and frustrated. No A/C, hot and angry, after a full 8 days of waiting for Master Tech to get back to me regarding setting up a service time, I decided to march my happy backside straight to their physical location to demand answers. When I showed up to their office (I had to take time off work in order to do this, which is piss poor service in my opinion...that I should have to go to them in order to be heard and helped), the lights were off in the lobby. I could hear a woman talking somewhere, but no one rushed out to help me. Finally someone saw me and asked me what I needed.
I told them my name and that I had been calling them and so had my home warranty company and that I couldn't seem to get a response regarding setting up a service time. The woman informed me that they were about to call me that day (to which my skeptical mind thought, suuuuuure). The woman said they had been waiting on the home warranty company to contact them to confirm that we wanted the service done. This had to have been complete BS, because my home warranty company and I had been calling them incessantly for over a week. I was able to schedule my service for the next day.
Long story short(ish), the technicians came out, installed the unit; they spit their dip tobacco slobber in my front bushes. They didn't give me an owners manual or any paperwork. I have since called my home warranty company and had them remove Master Tech as a vendor for any future work I might need done. NEVER USE THIS COMPANY. THEY ARE A NIGHTMARE. And impossible to get a hold of. Very shady.

I did receive a call from the manager who did apologize for the wait, he was very friendly about it. I understand its that time of year and they are busy. He did take care of things.
Thanks

NEVER use this company, they don't do what they say and they lie about it!!!!
Got a text at 1:34 saying they were on their way. I got home in 28 minutes and tech was no where in the neighborhood!! Took over 30 minutes to get someone on the phone and then it took them 15 minutes to 'reach the tech'. Came back on the line and told me how they had been on the phone with him the whole time, he ate his lunch, etc, etc (maybe they should be answering customer calls instead of chatting with a tech for 30 minutes!!) Best part - my neighbor saw him drive up and leave - was there less than 5 minutes - I told her this and she still claimed he waited 30 minutes!!!!

Update: The owner did reach out to me and offered to fix the problem and pay me back for anything I had to spend back in May. My home warranty company has assigned this company again to us. We are giving them a second chance with hopes that they will be great.
My home warranty company sent them my claim when my AC went out. Myself and my husband tried to call many times, sat on hold and left an voicemail. My home warranty company tried to call and email as well. I understand that AC company's are very busy this time of year but I couldn't even get ahold of anyone just to see if they were actually available to come out. It's very disappointing because my mother in law had good things to say about them. Maybe if you have time to wait around for a call back they are worth it but if you are needing to speak with someone right away, then I suggest you move on. I am just looking to save someone else some time and frustration.

I am very disappointed with how my service was or really has not been handled. My AC has been out for 5 days, I filed my claim on Sunday 5/13 and Master Tech was supposed to contact me in 48 hrs, I had to contact them, the best they could do was set me an appt today Friday 5/18/2018 between 2 and 5pm, as of now 6pm, no call from them, I had to call them, when I did call I got Rachel the customer service manager who actually hung up the phone on me and was quite rude in my opinion. Its now past 6pm and no call, Rachel assured me the tech would call me and not go home until my service was complete. Well still not complete. This is horrible customer service, I tried to call Master Tech and now all I get is voice mail for Rachel "the customer service manager" I am guessing since its Friday Rachel wanted out of the office. Now that I have taken work off for the afternoon, I will have to contact my home warranty again to start all over and still no AC.

My home warranty paired me with this company. The customer service is excellent and they have a very friendly staff. However, expect to be on hold for a very long time before you actually talk to someone. I called several times and was on hold for 5-10 minutes each time until I got impatient and hung up. It was a very nice experience once I got someone on the phone. I understand they A/C companies are extremely busy during the summer so I don't hold this against them.
My A/C was working but it did not have a lot of pressure. Turns out the air filter was filthy and needed to be replaced (I know, rookie mistake). Per my home warranty, I am to pay the cost of the repair or a $100 service fee, whichever is less. All the technician did was test the pressure and then pull out the air filter. This must be a high priced company because it was cheaper to pay the $100 service fee. The customer service here was great but I would shop different companies to find a cheaper rate before using this company again.

I am editing my review. I received a call from Matt, who I believe is a Co-Owner. He informed me that he'd read my initial review and was very concerned about the service I'd received. He informed me that the plumber Adam was no longer with them. He gave what seemed to be a sincere apology for what we'd experienced. However, he went a step further by offering to replace my sink at NO charge, as well as attempting to accommodate us by offering to have a plumber come out on the weekend, in an effort to keep us from taking off work.
I can respect a company who is willing to own-up to their mistake, and put forth genuine efforts to make good on them. The faucet was replaced with one that was an upgrade from the previous one.
Since this review does not include a full name, it took some effort to find out that I was the customer that wrote the original review. I was contacted by and owner. The BAD employee was no longer working for them. My faucet was replaced to my wife and my satisfaction. For these reasons, I would recommend this company and would use them again. Due to my original experience, I can't get them a 5 star, however I will give them a 4, with the opportunity to earn a 5 when I call on them AGAIN!
