Reviews of local pros in Merced, California

If you’re looking for an honest HVAC contractor to fix your air conditioner! Look no further. Zac was there for us when we called on a Sunday to assist us over the phone. Monday morning Zac was at our doorstep at 9am. And just so you know this is during a heatwave in the Central Valley when most HVAC contractors won’t even answer the phone. If you’re reading this review to find someone to fix you air conditioner, you’ve found your man here. Commitment to excellence is what you’re getting with ZACS Air Systems. I’ll definitely be recommending him to all my friends and family. Thank you for your good old fashion service! Greatly appreciated!!

During the sweltering heatwave my A/C went out…to make matters worse it was on a Saturday morning. I am so grateful that I found ZAC’s listing. I am reminded of a time when service people treated you like a neighbor. Straight forward, fix what’s needed and fix it correctly for the least amount of money possible cuz that’s the right thing to do. Wow!! Zac is trustworthy, kind and knowledgeable. I recommend him very highly.

Our AC started making a terrible noise and hasnt been working well. Called Zac yesterday, a Sunday, he answered and schedule an appointment with me for today. He was very friendly and knowledgeable. After about 20 minutes of him being on the roof he told us ours was the dirtiest he has seen in awhile. He spent quite a bit of time cleaning it and sure enough! The noise has stopped and the air inside is sooo much cooler! Great service, didnt try to charge me for things not needed. Wish I had called him earlier. Ill start using him for maintence once a year and any emergencies.

Zacs heating and air is the only business I will call. Has always been prompt and more than fair.. actually tried not to charge me one time ! Who does that these days...Zac does . Luv these people.

It was a scary moment when our HVAC system went out. With their knowledge, experience, and professionalism, they were able to take care of my family by providing high quality service. Let them be your first call for your HVAC needs.

Quick, kind, competitive price. So fast on the phone with same day service when it was convenient for me, Zac rocked and fixed my AC before it hit 100 again. Can not recommend a more trustworthy and respectable person.

Zac with ZACS AIR SYSTEMS repaired our heater recently. 12/10 Would recommend Zac to anyone needing heating, ventilated & air conditioning services!

Zac responded fast, and came out the same day to take a look at our heater. We needed a part to repair our heater and Zac gave us options to go to Modesto to get the part, wait the shipping, or overnight it. We happily chose to wait the shipping. Zac updated us on the parts early arrival, and urgently came back to repair as soon as it arrived. We thank and appreciate Zac for his professionalism, communication, urgency, and overall quality of work. Moving forward, we will give him a call for any hvac need and always refer his business to friends, family & strangers! Thank you again Zac!

Zac was very professional and didn't try to sell us something we didn't need. He did a great job installing a mini split unit for our master bedroom. He showed up when he said he would and finished on time as well. He was very professional and personable. Will definitely recommend him and also use him for any future work.

I want to share my positive experience with Zac who came to refill my air conditioner. I'm grateful that they arrived earlier than the scheduled appointment. The service was prompt and efficient, and my AC is now working perfectly. Thank you for the excellent service!

Thank you for coming out and fixing my ac unit. Zac came out to replace a motor and a clogged pipe that caused a little leak in the attic and he was very professional both times. He came out asap to fix our ac in the middle of a heat wave so I'm extremely grateful for his services.

My A/C unit suddenly stopped cooling during the recent heat wave here in the hot Central Valley of California . I called Zac’s Air Systems located in Merced,Ca., and within an hour Zac arrived at my home .
Zac throughly inspected my A/C system & was able to properly diagnose and identify exactly what components had failed causing my A/C to stop cooling. Zac didn’t just “ throw parts” at the A/C system or assume components were bad. Zac took the time to properly test & inspect each component which ultimately saved me over a thousand dollars by identifying a component that I had no idea was still under the original factory warranty!
Zac took care of the entire warranty process on my behalf and replaced the components in a timely manner. My A/C unit is now back working properly and is keeping my family cool!
Zac was very honest, professional & knowledgeable in his area of expertise!
If you have any problems with your A/C or Heating system and want the job done right the first time and at a fair price, I highly recommend Zac’s Air Systems! You will not be disappointed! Definitely a 5 Star experience! Thank you Zac’s Air Systems!!

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.

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.

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.

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!!

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!

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!

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.

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!

Zac and his team are super nice and professional. Zac stuck to his word and everything went smoothly and fast! He took care of my A/C issue seamlessly. I have utilized his services before and am a happy returning customer! Thanks so much!

Call them in a Sunday Morning, show up within an hour. Technician Jack was great and knowledgeable. Owner Zac showed up later and guided us tru the issue that was solved ASAP. Great service!!! 100% recommended.
