HVAC reviews in Fresno, California

Five out of five stars no doubt about it. One of the most honest owners and team I’ve ever met. Jennifer and Lisa are amazing receptionists and the technicians were there within 24 hours diagnosed everything same day and got the work done. Same day. Pricing was very transparent. I would recommend them 100 times out of 100.

Your technician Martin was awesome! He was very nice, knowledgeable and quick to fix our A/C. We highly appreciate the help and would recommend them 100% going forward!!!

We’ve had Nalk come out to our house twice for seasonal maintenance and also to repair our AC, and it was 5 star service every time. Good communication, fast service, and the techs are always helpful and friendly.

Love this company. They were fair, reasonable, and very professional!!

We only have good things to say about Nalk. This is our 5th year having them service our HVAC units in our homes. They are prompt, trustworthy, and professional. Ruben did an excellent job for us maintaining our heaters today.

Nalk Air Conditioning and Heating is the Absolute Best. Superior service prompt, fully explains everything in detail. Very respectful and reasonably priced. Call Nalk Air conditioning and heating I promise you will happy. :) 5 stars for Juan he is the Best!!! He serviced by sister's Air Conditioner today 8/7/25 excellent service!!

Juan was courteous and helpful. He performed the maintenance service in a professional manner

Ruben was amazing. Very knowledgeable and courteous. Had to replace a motor. Had it on the truck and ac is working great again. Thank you Nalk you never disappoint.

We pleased to say we had a great experience with the AC company. From the prompt affordable service, friendly staff and knowledgeable technician. We appreciate the automation and quick response. We will be calling back in the future.

Our prior service agent had not been doing his job! Poor air flow and pressure after each service! Well we had our regular scheduled service today, Super Juan came out and actually did a fantastic job serving our AC unit. Much better air flow and the unit was actually cleaned thoroughly!! Thank you super Juan.

They came out same day mid July !! to diagnose my mess of an ac installed by another hack company. Juan was professional and informative. I really wish I would have called them first! But they will definitely be the last company I use!

Great Service! They came on time and completed the task with few minutes and provided guidance for next steps. Will recommend this company to anyone in the central valley.

Fabulous service from scheduling the service to the technician showing up and doing great work!! He was so thorough and had everything needed to fix my AC all within the same appointment.

NALK AC was able to repair my AC system vs. total replacement saving me thousands of dollars. I appreciate their honesty and efforts to help save me $$$.

Ruben identified the problem quickly and repaired the issue promptly. He then explained the problem and the repair. He was prompt, courteous and knowledgeable.

Ruben was great and gave us helpful information and tips about our heating system.
Highly recommend!

This company is absolutely amazing! From the woman who scheduled my appointment to the man who serviced my AC unit. Great work by very knowledgeable, friendly, and professional staff. Martin knows what he’s doing! Service was done in a timely manner and issue resolved. 10/10 recommend!

I was very pleased with the Service from Nalk Air Conditioning. The AC Technician Angel 😇 Did a fantastic job. He was very knowledgeable and was very thorough at his work. He was able to fix the AC unit that, another AC company said, the AC unit was not repairable and needed to be replaced. I’m very thankful he was able to repair the AC unit.The temperatures have been rising. And we have a hot weekend ahead.Angel 😇 saved the day!!.. Thank you for sparing us from the dreaded heat!!!.. I would highly recommend Nalk Air Conditioning..

Nalk Air is absolutely fabulous. You will never regret calling him for any services that you need. Thank you again Ruben.

Everyone was professional & friendly. Their prices are very reasonable. Everyone was very helpful. Martin, Ruben, Juan & Lisa were all amazing people to work with. I’d highly recommend this company! They stand by their product & their work.

Nalk’s employees were very professional and helpful, from the office to the technician that came out to my home. I will be calling them without a doubt in the future :)
