Return visit today for Nalk to install our new extended safety roof platform around our recently installed HVAC unit. Just like they did for the install of the HVAC system, communication was excellent. They called and texted the date and time for installation They texted when they were on their way and they arrived when they said they would. Once again their bid was competitive and the safety stand is well made and fits perfectly. All personnel are professional and reflect great customer service. I highly recommend Nalk for you HVAC needs. read more

I just completed my semi annual service check-ups on both of my units and as usual, they were prompt and efficient! Each and everyone of the service technicians are great. Super easy to talk to and do a fast, clean and efficient job. It says something for the company when you have the same technician coming year after year and also the same girls in the office that you talk to, it really is a family atmosphere. Thanks Nalk!! read more

I was surprised & didn't expect this October's rainfall to remind me of another time unexpected rain fell. Late summer of 2024, our 20+ year old Goodman AC "retired". My 24 year old grandson who had watched the old AC put in when he was a toddler, said to get estimates from four AC companies. I did. Nalk, a licensed, insured & highly recommended company was very informative not only about the quality of the AC needed, & chosen, but explained the process of installation from start to finish, the costs, including Fresno city expectations. But ACs are costly so I had to wait & have Nalk install later. In the Spring of 2025, Nalk had available days & even scheduled the installation on a day my grandson could be there. On a bright, warm sunny day with some moving clouds, the two installers arrived on time and explained the process to both of us, in detail, as work to be done before and after the arrival of the AC, including what Fresno City expected and then went to work. Their preparation over, the new AC arrived and was now raised & in place on my roof with Nalk's two men installing carefully. SUDDENLY, a DOWNPOUR! Being concerned (water & electricity) I asked if they should take a break? No problem, no electricity on they assured me & with rain gear, protected themselves, the AC, the area, & continued working. The rain lasted a short time. When finished they again explained what was completed & that Nalk is available for any concerns. That's dedication to arriving on time, sharing info and safely doing and completing a good, honest job, rain or sun . Much thanks to those two pleasant young men & Nalk for that & quality & honesty. Hope to have Nalk's regular AC checkups. read more

My son was employed with Nalk Air Conditioning and Heating years ago. It was because of his knowledge of the company that we purchased our unit from Larry back in 2006. We have our maintenance with Nalk ever since. Employees are knowledgeable and professional and friendly. read more

I would like to say thanks to Larry for sending out Ruben. I was a add on for Monday; but since I missed work today Larry had Ruben come service my AC so I didn't have to miss another day. I really appreciate that from Larry. He really cares. Ruben was awesome and respectful of my place. He listen to my concerns and explained what needed to be done. No BS from him. I would recommend this place. Again thanks Larry and Ruben. read more

Ruben was promptly and courteous. He took time to explain and got it done the same day . The price was reasonable . The best thing was that they were fast and delivered like they promised . Thanks so much for your service Ruben read more

I want to say Thanks to Larry and his team!!!! What a great job they did today. After three bids for a New HVAC, I am so happy that I went with Nalk. Everything went so smooth day. The team arrived in three trucks and went to work. And I was amazed because they were early to get things setup. So when he said they would start at 9am.....they started at 9! And again Amazed, 2 1/2 hours later my new unit was hooked up and running perfectly. I now have the biggest smile on my face after 9 days without air. read more

Our air has gone out twice at the condo that we are currently living in. The first time someone came out, not to sure what his name was or what happened but it didn't get fixed correctly. Today to correct the issue they sent out Ruben. He was very efficient, polite and most importantly fixed the problem. I didn't feel like I needed to stand over him the whole time, he has a comfortable, respectful vibe, which I appreciate the most when someone's in our home. The reason I'm giving 5 stars is because of him and because of how fast they were able to make it out here on such short notice. Thanks guys, keep it up! read more

Upon returning to our Fresno home a few weeks ago, we noticed that our heater would not start. We had used Nalk A/C for maintenance work on some rentals and had been satisfied with their competence and their work in general, and called them out. They arrived, went upon the roof and returned, saying that the ignitor was broken, and they could fix it for $465. I asked them to leave the estimate and paid for the service call - $65, which included them "hand starting" our heater. They said that when it reached the set temperature and turned of, it would not reignite, because of the broken ignitor. . I went online to find an ignitor - $ 17.95 on Amazon, compare to the $279 listed on their estimate. Also, YouTube showed how to replace within 15 minutes. However, the real interesting thing was that when the heater shut off, the next morning it automatically restarted! The Ignitor is good, and works. So, they were going to charge me $465 to misdiagnose and not fix the problem. Perhaps the company has changed hands, because these servicemen were incompetent or crooks, or both. Do not use them, as they are not up to their previous standards. read more

Of course the circa-1972 HVAC unit decides to take a dump during the sweltering heatwave we are currently enjoying. Called everyone and their mother to come fix it. Nalk sent someone within 24 hours. The guy who came out fixed the problem quickly and was honest (more than I can say for many of the repair folks in this town). At this point, I would recommend them. read more

They always respond quickly and are knowledgeable. Their prices are fair and technicians are professional!

The best air conditioning and heating business in Fresno excellent craftsmanship on time absolutely wonderful to work with....I highly recommend them. read more
