HVAC reviews in Fresno, California

They are always a pleasure to deal with. They offer a good product, professional installers and their service is top notch. Daniel their service technician is such a pleasure to deal with. He arrives on time is knowledgeable and does a great job servicing my system

We went through a very thorough bid process, getting proposals from several highly rated companies. In the end, California Indoor Comfort with Keith and his team was the best choice for us. Keith went above and beyond to answer every question, provided three different system options without any pressure, and explained the pros and cons of each in detail. He also offered indoor air quality product options upon request and was always prompt in his responses.

We were specifically interested in an inverter system or at least a 2-stage unit, and Keith’s expertise helped us confidently choose a Trane XV18 heat pump. Their labor warranty was competitive and unlike anything we were offered by other companies.

Installation by Daniel and Jose was excellent. They worked with care, made ductwork adjustments to fix a hot zone in our home, and returned promptly to install the UV system we added. The final install looks clean, the system runs beautifully, and the entire process was professional, responsive, and pressure free.

We are very happy with the result and look forward to working with California Indoor Comfort for years to come as they service our equipment. Highly recommend them to anyone looking for a reliable HVAC team in or around Fresno.

All smoke detector batteries were changed and the one in living room must be up 20 feet. Daniel was technician that came out and was so polite and nice and handled it quickly and efficiently. He even changed out a few light bulbs that were burnt out for me as being a senior I can't go up a ladder. I recommend them highly and will inform all family, friends and clients. Thank you so much Daniel.

I have been using California Indoor Comfort, Inc for three years, not just for annual preventive maintenance on my two units of HVAC, but also for couple of repairs. The owner Keith always provides fast services when repairs our needed. Technician Daniel is very skillful and great to work with. I go with this company because they are knowledgeable with my TRANS HVAC systems. Price wise I think this company is fair though I don't know the real market pricings. I just renewed my 4th year (2026) preventive maintenance contract with the company.

If you’re looking for honest and timely work to get done on your AC, this is your place. I scheduled a quote on a ducting issue & high PG&E bill.. Daniel and Keith came through with a great price after getting quotes 3x the amount from 2 other companies. Parts were ordered and the job was done within a week. They had financing available to me and I am soooo happy with everything. I don’t usually leave reviews but this company is exceptional and qualified!

Scheduling was easy and I received a call beforehand to confirm. The technician was great! Very knowledgeable, kind, and honest.Fixed our gas fireplace with a new thermocouple and connected the switch for easy off and on from the wall as opposed to the unit. Daniel was wonderful!

California Indoor Comfort is the best! Daniel is SUPER knowledgeable as a technician, shoots you completely straight, is incredibly clean and meticulous in his work. We are always pleased to have him anssigned to our home because there is a level of comfort in having capable technicians available who are kind, responsive, responsive, and honest! Thanks for the timely and effective service!

Thank you CIC, I took you up on your offer of a free second opinion on our HVAC units per your website. Turns out we did not need 2 new units costing approx $30K, only a new fan and motor in the attic for $1K, a savings of $29K. Do yourself a favor, call CIC for an honest second opinion, service or maintenance, Daniel is very thorough, honest and a wealth of information. Thank you CIC, see you in May for our AC maintenance. Shame on Allbritten.

Great work. Stellar service. Would recommend.

Knew exactly what was wrong with our AC unit and got it fixed immediately!

Awesome service. Fair and reasonable and super professional. Will use their services again. ☺️

Amazing customer service. I highly recommend this company to anyone in need of any HVAC services. They’re knowledgeable, efficient, and reliable.

Optimum air was awesome very punctual and professional and had all the parts to complete the job without having to leave and comeback . 10 out of 10 will use again !

Robert and his crew were very knowledgeable and had great customer service. First hot day of the summer and AC stopped blowing cold air, they had it fixed by the afternoon and it’s worked great ever since!

Had our AC go out in the dead of summer! Robert and The Optimum Air team had us up and running in no time! Highly recommend for any of your heating and air needs!

It’s hard to find good technicians in any field nowadays but these guys know what they’re doing. Very reasonable rates compared to others I got quotes from and they answered every question that me and my wife asked them. I would highly recommend these guys to anyone. A+++ Keep up the good work men!!!!

Had problems with mini split unit! He found wasn’t installed correctly and found it had a clogged drain!He arrived on time he not only explained the problem but showed me the problem and explained how it would be fixed! I have since referred him to 2 of my family members who were both pleased with his work! Quality service in a timely manner hard to find these days!!

Very professional! They took time to ensure all my A/C issues were resolved in my home which needed duct work fixed and a failing outside unit replaced. From start to finish they took care in making sure to not track any dirt in by kicking off their boots. No one I would rather call them a local hard working guy like Robert!

Optimum Air Conditioning & Heating replaced my ac unit a few years back at great price and was very efficient. The workers were very knowledgeable, helpful and friendly. I highly recommend these guys.

Optimum Air Conditioning and Heating did a fantastic job installing my new AC unit. They were professional, efficient, and the quality of their work was excellent. I was also very happy with their pricing. I highly recommend them for anyone needing AC installation or service!

I cannot recommend Optimum Air Conditioning & Heating highly enough! From the moment I contacted Robert, his professionalism and responsiveness stood out. He arrived on time, was courteous and clearly explained every step. Not only did he diagnose and repair the issue quickly, but he also took the time to ensure the system was running efficiently before leaving. No upselling, no unnecessary delays; just honest, reliable service from someone who is clearly an expert.

If you're looking for an HVAC company that delivers stellar service with integrity, call Optimum!
