GNS Heating and Cooling

I have worked with GNS Heating and Cooling for several years now and their commitment to punctuality and dependability is spot on. I am a Farmer and Processor in the area and their technicians always call before heading in and keep us updated and address any AC issues promptly and efficiently. I never worry about them not showing up, or communicating with us. The company's management is super organized, and it shows.

Thank you so much for coming out so promptly and getting our AC unit up and running again! When I called this morning, I was quoted a time. and then got called a little while later and asked if the technician could come earlier! Heck Yes! Oto, the technician, was professional, knowledgeable and friendly. We will surely recommend GNS heating and cooling to all of our friends!

We’re very pleased with our new HVAC system. The estimate was was thorough and we were offered options of different efficiency ratings. Once we decided which system to go with it was only three weeks until all material was on hand and our installation was scheduled. The install team showed up as scheduled and went right to work. They were courteous and professional and very willing to answer any questions. Installation was completed in one day. The work is first class and the only cleanup we had to do was to mop the floor and that was minimal. Thanks GNS for a job well done!

GNS installed a 5 port ductless system on our house. From the very beginning of the process to the end everyone was helpful, friendly and professional.
I recommend GNS to a lot of my customers based on all of the positive feedback I have heard from other people but now I recommend them based on my own personal experience.
Not everything went smooth but that is why you hire professionals. Because even though there were bumps along the way in the end everything was taken care of and correct.

The team at GNS are prompt, efficient and courteous!
When our 16 yr old AC unit went down they were prompt to troubleshoot, search for and order the necessary parts and install them. Due to the age of our unit, parts were a little harder to find but they persevered and got our unit up and running. There was never any suggestion or sales pitch for a new unit, only prompt action for repair, saving us thousands of dollars. We appreciate their honesty and integrity.
Thank You GNS team!

Great service. On time and professional which is why we have used them for years.

We needed our air conditioning systems replaced. Guy Nolan came and gave us pertinent information regarding what was best for our home. He recommended several good options for replacing both of our air conditioners. His staff was friendly and professional while they installed the systems. They cleaned up any debris they had before leaving each day. They installed the systems in a prompt manner. I highly recommend this business and staff.

Oto came out to service our air issues. He was so polite and personable. He went above and beyond to get us all fixed up. Thank you so much Oto. God Bless.

After several estimates from other companies and areas that we had lackluster responses from we were recommended to GNS. We are so grateful and thankful to find them. They installed our new ductless a few yrs ago and we do biannual maintenence them. The are the best company we have dealt with in Arizona. They are the Pros. Dont hesitate to call them. Totally professionals.

They did a great job on our heating systems removed the old ones and ,installed the new heating systems. As well install our wall hot water heater works great. There work quality of work was excellent as well they saved us allot of money on all three items two heating units and the hot water wall unit. Very impressive work ethics. Thanks to all the men whom helped to get this work done and Mr.Nolan you have a great team .

GNS is an honest company that excels at quality & efficiency. After a thorough inspection, it was determined that our two AC units needed to be replaced. Two crews were sent & worked tirelessly to ensure that our systems were installed correctly and quickly. They were the most cost effective quote & their crew was professional and knowledgable. Thanks GNS for getting us back to cool!

The guys that installed my furnace were very polite, performed great work, and pointed out a loose gas pipe that could have turned into a problem. They fixed it for me for no additional cost. I really appreciated that they went above and beyond without having to do so!!

We got a mini split unit to cool/heat our tiny home. They were able to weld a frame for the unit to sit on onto the side of the house and run the lines in from there. We run our unit almost constantly during the heat of the summer and it keeps us super chill even on 105+ degree days.

We had some issues with the unit at first, but after calling GNS came back out and corrected the issue.

Very nice people. Called about a propane leak on a Coleman furnace and within 2 hours there was a service technician out and diagnosed the issue. Had it repaired two days later. Will not call anyone else for services these people offer. Five stars!

The staff at GNS was very professional and courteous with the installation of our AC unit. They were very responsive to our needs and did an outstanding job. I would definitely recommend GNS.

I called mid-afternoon and was able to get someone out within about an hour or so. Everything was explained well and pricing was clear and upfront before work began. The tech was knowledgeable, friendly, and professional.

Amazing service. Hank was the man who took care of our evaporative unit. He is the one you want. Good people and fantastic service. Would give 10 stars if I could.

It's tough to trust HVAC companies with whom you've never worked. You just never know the quality of the customer service you are going to experience regardless of who recommends them. GNS Heating and Cooling out of Willcox, AZ came highly recommended so I took a chance. This company is top notch. Very professional and they took care of me faster than I expected at the price they quoted. I'd recommend them to my family and friends without hesitation and I will use them from this point forward for my HVAC needs. Thank you, Mason. Pleasure working with you, sir!

I have had GNS do a number of things for us on several properties we own. They have always been fair and prompt. I highly recommend to anyone need hvac services in South Eastern Arizona.

Great service from office and field staff
