Zac provides honest professional service at a reasonable price. These guys are the best choice in town. I asked Zac to come out for a second opinion. Previously Blaine Heating and A/C had come but they were unclear about what would fix the heater, they wanted to replace part after part, and the cost kept rising. I’m glad I called Zac. He answered his own phone and came out immediately. He recommended a yearly service rather than replacing costly parts. My heater is working in one visit and I’m paying a fair price. Also gives Military discount 10/10

Zach and his technician were excellent completely responsive immediately efficient and got my two heaters working for my two homes within just a couple of hours of my first call. I’m super grateful and our whole family is nice and cozy now. Having him give me a quote for fixing the Cooling system systems now.

Zac, you went above and Beyond, your Service was the best ever. Given the circumstances, you arrived at my house at 2:20 and did not leave until almost 7 o’clock. Thank you so much for what you did for me and making sure that I had heat in my home tonight. You are an amazing guy. I appreciate your service and everything that you did. Thank you, Zach.

Highly recommended. Came across them last year and they fixed the issue the same day. So it was only right to call them for a system maintenance. Great customer service.

⭐️⭐️⭐️⭐️⭐️ ZACK AIR SYSTEMS came through when I needed them most! Frank quickly diagnosed the issue, explained everything clearly, and got things moving ASAP. He was professional, informative, and efficient. Zack followed through right away, understood the urgency, and made sure the job was done fast and right. On top of that, the price was very reasonable. I really appreciated their responsiveness and care—highly recommend!

I highly recommend Zac’s Air Systems. Not only did he show up on time, but he scheduled an earlier time with me when he had an opening pop up. He did a full and very thorough service on my AC unit, which you could see by the photos it definitely needed. I was just expecting a before summer service but he found a few maintenance issues that if left unattended would become an issue in the future. He gave me the option to fix them now (if I wanted to) to avoid a future service call. I opted for him to make the repairs and I thought his price was more than fair! After he was done we went inside for a function test and it was pumping out cold air faster than ever! I don’t often write many reviews like this, but I felt like it is well deserved in this case. I will be using him every year. Very happy and highly recommend!

ZACS Air Systems is by far the best in town, with customer service being there first priority. They don't keep you in the "mist" but instead inform you of where you are and what you truly need. Had the best night sleep in 6 years and couldn't be happier!!! A+ business!!!

I got home after a long day of work to find out my AC was not working. On a Sunday and after 7pm I was super bummed thinking no one would come out. I remembered seeing some positive posts about Zacs services online so I figured I'd give it a shot. I called the numbe and Zac literally came out, assessed the issue and fixed my AC all in under one hour. He was super professional, up front about pricing (very fair pricing) and just a genuinely kind person. Extremely happy I called him. Thank you Zac!

I just wanted to take a moment to share my appreciation for the exceptional service I received from Frank. He came out to help me repair my Lennox air conditioning unit, and I was truly impressed from the moment he arrived. Frank was fast, knowledgeable, and clearly experienced. It was immediately evident that he understood my system inside and out. His ability to quickly diagnose and resolve the issue gave me great confidence in his expertise, and I’m so grateful for the help—especially during the heat we’ve been having! Thanks to Frank, my AC is running perfectly again. I wouldn’t hesitate to recommend Zacs to anyone looking for a trustworthy and reputable service provider. You’ve definitely earned a loyal customer.

I had another company come out and tell me I had to replace my AC unit. Zacs made time in their schedule, same day, to verify if it needed replacing and it did not! I was a simple part replacement. They literally saved me thousands of dollars! All the guys were friendly and honest and did a great job. I will call them for any future HVAC needs! Highly recommend.

Exelent work and customer service, I called Zac for the firs time today in the morning, we arrange a 2 hours time frame and he came by on time, he also told me what the issue was with my furnace heater, and gave me an estimate to fix the problem, and i told him to fix it so it could solve the miss function on my furnace heater., and now my furnace heater is working out normally, I would strongly recommend him to service your AC or Heater problems.

Had issues with the ac blowing warm air and shutting off in 100+ degree weather! I called Zac on a Sunday in the evening to book an appointment for the next day but he squeezed me in last minute and promptly came to check what was going on. I'm so grateful for the service despite the time I called, especially during this heat! He kindly explained what was wrong and gave me a first time customer discount! I most definitely will continue using Zac's Air System's services in the future and strongly recommend them!

Overall a great experience! I really appreciate that he is available on weekends, so many companies are not. Zac came out same day and was diligent in trouble shooting my HVAC system. He took his time in explaining what he was doing and looking for during the process. I would recommend Zacs Air Systems and will be reaching out to him in the future. Thank you!

Today I called Zacs Air to see if they were the ones who took care of my air conditioner last year. They were. I talked to Zac told him what was going on. He was busy but said if he had a cancellation he would come out. Prayer works. Zac called me said he would be at my house in 10 minutes. He was. Zac and his coworker came and did what they do best professionally. They fixed the system and now I'm good. Zac was very kind in service & fair with pricing. If you need good. No I mean great service give them a call. You won't regret it. Thank you Zac.

Zac was so great! I called him at 8AM on a Monday and by 8:30 he arrived to my house in Atwater. He fixed so many things that were wrong with our home and was so upfront with everything. He was also super honest, which is hard to find these days with repairmen. I highly recommend you go with Zac for your AC needs and make him your go to. He sure is ours!

Zac's has excellent customer service, timely responses and doesn't try to upcharge you with service you don't need. When they give you time window of when they are going to show up, they show up in that time frame and text or call you to let you know they're on the way. Highly reccomend Zac's!

AWESOME! Zac’s the guy you call when you need help with AC or heat! ! He goes above and beyond, is customer oriented, kind, and knows what he’s doing. I called him at the end of finishing a job out of town and he was at my home within 20 min. He saved me from having to replace my AC unit by going above and beyond and trouble shooting some issues. Thank you Zac (and Frank). Your time is much appreciated!!

Contacted Zac’s air system. After explaining what the issue was. He was able to go over that same day, and took care of the issue right away. I live out of the area so was not there in the home. But he kept me informed the whole time. He was quick to fix the problem. Will definitely save his number, to keep doing business with him since his services were quick and very professional.

After explaining my issue over the phone Zac’s air systems fit me into the schedule almost immediately! So soon during this busy time I wasn’t ready for the response. After arriving and diagnosing the issue he installed a new thermostat I had and fixed a wiring issue. All of this was after another A/C company attempted and were unable to find the issue! Zac’s air systems stayed in contact for a few days to make sure the problem was addressed and need no further response! Oh and a good personality.

HIGHLY recommend you give Zac a call. Our office AC unit stopped working, I gave Zac a call and he was there in less than 40 mins. Gave me a quote, had the part he needed, and got the job done in an hour. He truly cares about the customer and he cares about his business and reputation and it shows with the quality of work and professionalism.
