I can generously say that I have used them before and would not use them again…read more I agree with the other warning review(s). I last used them 2 yrs ago and posted to Yelp my concerns but review was deleted. Paid for A/C services and had to have another A/C company come out. They said they cleaned a unit but below pictures were taken after their expensive service. They also tell you after the fact that there is an extra charge for using a credit card to pay for their service. Always tries to sell more expensive services. I'm sure they can do good work... but if you use them get a second quote/opinion.

By far the best service company I've ever had the pleasure to have out to my home. Eddie Sr and…read moreEddie Jr are both phenomenal men, who were polite and answered all questions that I had. Heather was wonderful to speak to on the phone, and quick to try and meet the needs that I had for scheduling. I just wish I could have met her! I had to have work done, not once but twice, and after the first time I requested their service for the second service call I had to make. The first issue was AC related, and Eddie Jr had my AC up and running in no time. The second call was made two weeks later for heating issues, and when Eddie Jr couldn't fix the secondary problem that was found, they were prompt in ordering the necessary parts and came out a few days later. Eddie Sr came out to replace the ordered parts, and made great conversation while still quickly working to repair the problem. After he replaced the part, he was thorough in making sure everything worked properly. I appreciate all the work they did for us, and will certainly be calling them for any other HVAC needs that we have. I will also be sure to recommend them to anybody who needs help!

Then me as the owner of the house . I was not there at the time and just a friend was there. So the tech was only there for a about 10mins and never called me. Just told my friend that the main breaker was a fire hazard and then left. So I called the main office and asked to speak with the tech and never received a call at all. And then I text the number that you can send a text and they just said that tech found something wrong with main panel and I would have to get with my warranty people. And till this day no one in person has called me at all from Montz.

Eventually the unit was replaced by a York AC/Heat Pump. For years I have taken advantage of the Marvin's Comfort Club which does a Spring and Fall tune-up each year to prolong the life of the unit.

His workers were able to use the casing, however the wheel had a small flaw and a small humming noise that I could only heat back in my master bathroom. I reached out again to Marvin's and once the replacement came in, they were right on top of replacement and now no hum and my son states his room has a much better air flow! We also had a HALO unit installed to help prevent bacteria growth! For a house built in 1969, she feels much better!

Seems the last two companies had not been cleaning the Evaporator, probably for over seven years. I rewrapped the lines (which had been seeping condensate after multiple tech repairs), cut out the intake and cleaned the Evaporator coil 4 times. It was bad due to lack of cleaning. I also installed an egg crate filter box return. After hearing 3 different opinions from 4 different HVAC techs, I called Mel. He showed up on time, listened to the saga, and checked the unit. He removed and cleaned the blower (which the last company said they could not access). He said the evap coil looked good and the inflow was fine. I love that Mel does his own work, and he does it right. He was calm, listened and knows his science. Oh, and he took care not to track up our carpet.
