Mina did a great job! He came over on a Saturday and repaired my wine cooler. He was timely, professional and knew exactly what the problem was with my fridge. I would definitely use him again for another repair.

Kevin installed our QuietCool ventilation system and we couldn't be happier with his work. He spent 12 hours in and out of our hot attic installing the system, patched the drywall up nicely after installing the vent, and had great communication throughout the process. Our home is so much cooler now and we are very happy with the results. We highly recommend kevin!

Adam was Awesome, Honest and Efficient. He is a Man who has love and passion for his craft. He told me how much it would be after I posted what the problem was. He didn't try to rip me off with those expensive diagnostics and crazy games people play trying to take all of your money. As a single Mom I thank God that there are still people with INTEGRITY left in this world. I had another company who came out and told me I needed a whole new system. I thank God for Adam and his company Planet Cool Breeze. He changed my wiring that my dog chewed up and added something to make the air cooler. You are what I prayed for and God sent you. I pray that you will have much success, blessings and favor in what ever you touch. I pray you will continue to flourish and prosper. Thank You! Thank You! Thank You!

The response was quick. Andy, the technician, was extremely knowledgeable, professional and courteous. I was expecting to replace evaporative coolers and was told that only maintenance was required. The estimate was very reasonable. Thank you Andy. I hope to be working with you very soon!

Power surges suck! Just the other day a car crashes into a power pole around the corner from where I live and the resulting surge from the exploding transformer burned through every charger and clock I had plugged directly into the wall as well as my fridge, oven and washer. I decided to give OC Appliance Masters a call and make an appointment for him to check things out the next day. I get a nice two hour window vs the 4 hour window that I've been accustomed to from previous experiences with professional service guys for fixing HVAC, electric, plumbing, cable etc. I spoke to Nick and he says he can call an hour or half an hour before the arrival time. Another plus. I was going to be home all day so I was okay with the half hour heads up call. On the day of the service Nick calls me earlier than expected and says he was able to finish his earlier appointment and if I'm available he can come earlier. I'm all for that! Who enjoys biding their time waiting for a service person? Not me. The sooner the better plus my fridge wasn't getting any cooler. When he arrives, he was a whirling dervish of information regarding possible culprits for what could be ailing my appliances and is listing them out as he's working on my fridge. He tells me he was a electrical engineer and will find out what the problem is. It turned out it was the controller board and he was able to give me an estimate immediately without saying he'd have to check the price for the part etc. This was a nice change from the other guys I've dealt with that don't say a word and have to crunch the numbers. What it told me was that he had experience with this issue before. He also had the part on hand and could get the unit back and running in no time. I was sold. After that, he also serviced the fridge's coils, at no extra charge, which were cluttered up with years of cat fur which he was shocked at seeing as he opened up my fridge's service panel. The next item he looked at was my stove/oven. Given what he saw with my fridge, his prognosis even before opening the stove/oven was that it would be expensive and I could be better off looking for a new oven but we'll look anyway. Turns out he was right. The digital display panel and control board were shot and would cost $700 if I wanted to have it fixed. Thank you for your honesty. Finally the dishwasher. Lo and behold, same problem as the others, burned out control board. Good news was that it was more reasonable to fix and wasn't going to cost as much as a new unit. Bad news was he didn't have the part on hand but we arranged for him to get the part and return to fix it later next week. The biggest take away from him during the service call was the preventative advice from Nick. Place ALL your expensive appliances on a SURGE PROTECTOR from now on. This is the first time anything like this has ever happened to me and this includes even when I was living in Denver and we would have some nasty thunderstorms that would cause power fluctuations like nobody's business so it never occurred to me to put anything except my computer and entertainment system on a nice surge protector. That's all changed now. All in all, it's hard finding a trustworthy appliance repair person. I read some of the positive reviews as well as the negative reviews of the well reviewed appliance service techs for the area and decided to take a chance with OC Masters and I'm very pleased with the results. I'm also glad that I'm dealing with a family owned and operated business since Nick and his brother are the guys who are doing all the work. HIGHLY RECOMMENDED.

Aaron is great. He cleaned our air ducts this fall, and it was just such a pleasure to do business with him. His rates were low, he was professional, communicative, and just a nice guy. My only complaint is that he doesn't handle all kinds of other home repairs, because I'd like to hire him for about a million other jobs!

I bought my house in Feb. Once it started getting warmer outside I realized that the warmer it got, the harder of a time my ac had keeping up. This house has a newer Trane (one of the best models you can buy) 20xli on it. But when it gets hot, it will creep up on temperature, once it approached 90 inside my house with the temp set to 72 and it going all day. I knew this wasn't right and called an a/c guy that my friend knows. He suggested a whole house fan. I took it into consideration. I had another ac guy come out, he "couldn't find anything wrong" with my unit and suggested he clean my coils first for 600 dollars😳 and then said "we will see if that fixes it and go from there. Not really the answer you want when spending 600 bucks. So I decided to deal with it. We had a few weeks of cooler weather so I didn't think much of it. This week it's been 100-109 outside and the temp inside around 2-3 pm is 80 or so degrees so I decide to come on thumbtack and put in a job request. Within hours Tony contacted me with a great price, and had availability the same day with 30 years experience. So I had him come over. Within 20 minutes he knew what was wrong and within an hour he had it fixed. Wow. Funny how much easier it is when you just have the right guy come and do the work. Thanks Tony. I'll use you for all future ac work.
