HVAC reviews in Modesto, California

Express my sincere appreciation for the exceptional service provided by Roy during his recent visit to service my heater unit
Roy demonstrated great professionalism and expertise, coupled with excellent communication throughout the entire process.
His thorough approach and attention to detail were very reassuring.
In contrast, my previous technician, Derek Sawer, appeared to lack the necessary experience w/ Havoc svstems and unfortunately caused damage to my AC unit a few years ago.
Given my overwhelmingly positive experience w/ Roy, I would highly recommend that he be scheduled to service both my heater and AC units twice a year moving forward. His knowledge and dedication have restored my confidence in maintaining these critical systems in my home.
I Thank you once again, Roy, for your outstanding service. I look forward to continuing to work with you in the future.

These guys installed a tankless water heater and some duct work for me a few years ago and when it started giving me problems last year I had my home warranty company come out and check it but they told me they couldn’t touch it because it was installed incorrectly and the warranty was void because of it. It’s missing an exhaust or intake pipe as seen in pic and other issues. When I reached out to Derek Sawyer their Service Manager Steve told me told me they would take care of it and asked that I send them pics and model and serial #’s and they never got back to me after my repeated calls and texts. They never sent anyone out or even called me back. I’m still waiting now I’m stuck with a tankless water heater that I can’t fix because no one will touch it because of their incompetence. I will have to pay thousands of dollars out of my own pocket to fix. I DO NOT recommend that anyone use these guys STAY AWAY from them because they don’t care about customer service, they cut corners and they only want your money. They suck!!!!

UPDATE 12/12/25: They sent me a message on here for show as you can see by there reply below. I called and made an appointment and they never showed up and when I called to find out why I was told they don't work on tankless water heaters and that they would get back to me. They never did. Don't use this company they don't stand behind their work and are dishonest.

I want to thank Isaac and Francisco for a job well done. They were very professional while installing my central heat/ac unit. Very clean in the area they work. And also I want to thank Ronny who explained the promotions in financing a unit. There was no pressure in the purchase process. Because of you guys we have a new unit. Thank you again.
I definitely recommend this company Sawyers.

We had Mario came in to our home for check. He was great! Highly recommended! He taught me things about the wires and how things work. How to maintain it as well. He always answers my questions as well. So happy to have him as our tech. You’ve done a great job

Excellent service good customer service

Wholesaler.
Will not sell to individuals

Grate supply ware house on the spot.And excellent service to.

There’s guys have very good products, very friendly.

They always have the parts I need in stock and a great selection of units. I might pay a little more here but it is worth it!

"supplier/wholesaler" doesn't sell to the public. Went on Amazon and got the correct capacitor for $12.45, next day shipping.

This place sucks been here for over an hour and these guys still can't get someone to unload my trailer. Instead they are hiding in the warehouse house some where because even the girl came out here to look for her workers🤣🤣🤣🤣 crazy.

I'm an HVAC contractor and got burned by this supplier. I was carrying the Gree product line and had a customer ask if floor mounts where wifi capable. I forwarded their question to heating and cooling supply. They responded with yes it is and I simply forwarded that response back to the customer. Customer signed contract and we proceeded with job. Once everything was installed we found out floor mount was not compatible with wifi and customer was livid. Rightfully so. Heating and cooling supply left me hanging with no solution. I had to take out equipment and replaced it with Mitsubishi while eating all the install costs. Heating and cooling told me I could bring back equipment, but next day when I showed up I was told no they cant accept installed equipment and that the person who told me I could return it didnt have the authority to do so. Since then I ditched Gree and moved on to Mitsubishi, I still have the equipment from that job sitting in my shop. About 4k+ worth of equipment as well as all the lost labor and mItsubishi equipment that cost me more then gree. Heating and cooling supply straight burned me. For such a small amount when I've already purchased close to 300k in equipment from another supplier this year it's hard for me to understand their logic. All I can say is of they will do this for such a small amount I would certainly advise anybody thinking about doing business with them to watch out. And maybe think of going elsewhere as their loyalties are not with the consumer. Sadly, they have lost far more from me taking my business elsewhere and the potential to loose a lot more from reviews like this.
I should add they where willing to take it back, then have me buy all my supplies from them and they would "discount" those supplies. Problem is they dont carry much of what I need and their "discounted" prices are higher then what i get it for elsewhere. What sense does that make? The one thing i asked for they never got back to me about it. Its been 7 months...
