HVAC reviews in Modesto, California

My parents are in their mid 60s to 70s and their air conditioner stopped working and I didn’t know who to turn to I found Cool Tech on the web and read the reviews. I called and Emily was very pleasant to talk to I explained what happened and she understood what I needed. Emily called back and said her technician was in the area and could stop by for an inspection. Jose showed up and went right to work he explained that my parents needed a new unit but also didn’t force the issue which was greatly appreciated he climbed back on top of the roof and was able to fixed the A/C. The personal treatment and professionalism received was really welcoming and I am gladly rating 5 stars for the Great service we received.

On two different occasions our AC unit went out. Jose came out the same day we called and was able to fix the unit both times on the same day of the call. He did a great job and unit is running well. I highly recommend cool-tech. Very happy with the service!

Install of new super efficient 2 stage heat pump. Start to finish Emily and Jose were fantastic! The crew was professional, on time and very hardworking. All of our questions were answered and addressed in a timely manner. We are very happy with both the system and the customer service. Couldn’t be more pleased. Thank you Cool-Tech!!!

Delighted with the speed, recommendation and quality of Jose + crew's work and Emily's responsiveness.
Got a 5 stage heat pump with all permits done in a timely and professional manner.
A friend referred Jose and I'm so glad I got my heat pump installed by Cooltech.
They didn't try to unnecessarily upsell or complicate the solution.

Ugh! My A/C went out in the middle of this crazy heat wave! I called Cool Tech, Emily was so helpful, extremely knowledgeable and very pleasant to speak with. She reassured me they would get my AC up and running ASAP. They put me on the schedule and the next day Jose came out. He walked me through what was going on and got my A/C up and running within the hour. He was professional- even wore his shoe covers inside my house without me having to ask! Prices were reasonable and did not cost me a arm and a leg. I definitely recommend!!

Cool-Tech was phenomenal to work with. Jose and his crew worked with our contractor through a home project we recently finished. They were very professional and the quality of the work put in has been great so far. They have always been very responsive in replying via phone, text, or email. Highly recommend this company.

Cool Tech has helped us with both of our properties for years now. Always does a great job, and doesn't rip you off. Jose was able to identify and fix many issues from previous companies' work. Much better when the job is done right!

Cool-Tech Heating and Air are the ONLY people I use to repair my air or heating. The Central Valley gets super hot in the summer. I have had some emergencies, where Jose has made time for me even after hours. I have not had to wait for parts because he has had them in his truck. He has saved me time and money. Not to say, saved us from the discomfort of not having cool air in the middle of a heat wave. He is a professional at what he does! You can never go wrong with this husband and wife team.

Customer service is top notch. Jose and Emily have gone above and beyond every time we have called them. Their quality of work is on the same level of customer service. If you are looking for a contractor for any HVAC needs, look no further. They offer quality products, amazing customer service and equally amazing work.
Their knowledge of the Go Green Finance program helped with the stress of the price tag and allowed us to go with a higher quality and more efficient unit that will save more money in the long run.

Cool Tech provided fast, friendly service when I urgently needed my heater fixed. I didn’t have to wait days, and they were quick and professional.

We recently completed a major home remodel and our HVAC contractor Jose was, hands down, one of the best professional we worked with. He installed a completely new system and took the time to walk us through every detail of how it operates.

What sets him apart is his honesty and eye for detail. He is incredibly knowledgeable, humble, and always clear about timelines and scheduling. No matter how many questions we had, he was patient and always made time to come out when we needed him. If you want someone who does the job right the first time and truly stands by their work, look no further."

After a quick 40-minute visit, the technician expertly restored our thermostat's functionality. So grateful!

Waking up to a cool breeze each morning feels like a dream come true since my AC got serviced. The technician’s skillful hands transformed my clunky old unit into a whisper-quiet marvel. I’m enjoying comfort like never before, and the efficiency boost is noticeable. Their attention to detail was top-notch!

Fast service, great service and friendly technicians,

Excellent service and concise useful feedback

Fast and prompt service. Pricing was reasonable and service was top notch

I can’t say enough good things about Next Day Air & Heating. My elderly mother woke up with no heat during one of the coldest mornings we’ve had this season. I called several HVAC companies, but Next Day Air & Heating was the only one that treated the situation with real urgency.

Their technicians were fully booked, but the owner himself came out to make sure my mom wasn’t left in the cold. He showed up quickly, was incredibly kind, and explained everything in a way she could understand. He had the heat back on in no time.

What really stood out was that they offer a senior and veteran discount, which means a lot when you’re on a fixed income. The pricing was fair, honest, and transparent — no surprises, no upselling, just genuine care.

It’s rare these days to find a company that still puts people first, but Next Day Air & Heating absolutely does.

Highly recommend them to anyone looking for trustworthy, dependable HVAC service.

Very respectful and reasonable! Extremely professional as well!

Very kind and trustworthy. They are family owned and have expanded from the bay area to my area. They have so many great reviews on their website . Thank you for helping us

Luigi Hernandez is another great representative of the DeHart team. When they came to fix the water main he was always professional and understanding to our needs. Definitely a 5 star member of your company.

It was wonderful having Ivan at DeHart take care of my home. He was very thorough and addressed all of my plumbing concerns. He was very helpful and meticulous. I couldn’t be more pleased!
