“We recently had a new A/C unit installed, and the entire experience was seamless. ​Miguel was our consultant and did a fantastic job and took the time to explain every detail of the system and the process, ensuring we felt confident with our choice. ​The technicians, Edgar and Josue, were equally impressive. They clearly took pride in their work, taking the necessary time to ensure our A/C was installed correctly and functioning perfectly. ​It is rare to find a team that is this thorough and professional. I highly recommend their services to anyone looking for a stress-free installation!”

“Very happy with the work. He knew exactly what was wrong and fixed it. Gave me insight on my older model equipment. Made recommendations Strait forwarded i highly recommended Cytech. They have my trust. And as a Vet that means something”

“Cytech has always been dependable and provided great service that leads to a permanent solution. You don't have to worry about having to call them back after they've been on site. You can find a cheaper HVAC guy out there, but they won't be as reputable or reliable as Cytech.”

“Our A.C. unit was not cooling well enough, turns out the inner and outer coils needed some serious cleaning. We have had good results from Cytech before. Called, made arrangements and within a few hours, our unit is back on line and cooling like it should. Thanks for the Great work and service. Oscar M.”

“Excellent, thorough service. The technician noticed my thermostat (smart device).had not been fully configured from when it was installed (also by Cytech, but different person) and completed the configuration. He also verified a higher than normal fan current on an off-brand air filter I had purchased so I returned it and saved burning up the fan motor prematurely. Very great service. High knowledge and high caring. I hope the company takes good care of folks like this.”

“Called them late in the evening yesterday. They picked up the phone! They set my appointment for next morning 8-12pm. They sent Carlos the tech and he was very courteous and professional. Answered all my questions, explained everything about my unit and what it needed and how much everything would cost up-front. Thank you Cytech for answering my call and thank you Carlos! My AC is working 💯 percent and I am a very happy customer 😊!”

“I originally had some concerns regarding communication around AC maintenance requirements and warranty coverage after our unit was installed. We were under the impression that the 5-year warranty provided more coverage than it actually did, and we later learned that yearly maintenance is required to help keep the unit operating properly. After speaking with the company, they were willing to address our concerns, issued a refund, and scheduled a follow-up service appointment for our AC in 6 months. I appreciate them taking the time to make the situation right and improve the experience. I would recommend that future customers ask detailed questions upfront about maintenance requirements, labor warranty options, and what is or is not covered after installation. Overall, I’m thankful the company followed up and worked toward a fair resolution.”

“Professional and knowledgeable staff. The company ensured that my house’s AC issue was repaired as soon as possible which makes a big difference when the temperature outside is over 100 degrees. Thanks”

“Very professional and prompt. Received several purchase options to choose from and since it was nearing the weekend they were able to secure the ac system and install on Friday. I highly recommend Cytech.”

“We are extremely grateful for this company. Finally got referred to this no hassle credible company. I was using someone else and they charged whatever they wanted or needed. A credible company is the best way to go to avoid crazy and unnecessary charges. Thank you Cytech for helping us with our A/C system.”

“Home warranty company could not send anyone to assess the issue with my a/c for over 2 weeks. Called Cytech and they were here that day, assessed, repaired and went a step beyond and found the drain line was clogged. The Cytech technician was very knowledgeable and had our house cool again in a short period of time.”

They will answer any questions you may have about their products. They will help with insurance claims, if any can be filed.

“Our heating and cooling system wasnt working when we arrived. They came after hours to let us know it was unfortunately shot. They gave us some freon to keep us cool until the new unit came in. 2 days later they were here to install the new unit. Friendly and thorough.”

“When no other company would come out and look at my mini split Cytech did. Tech came out and already knew the problem when I explained what was going on and yet he still did a thorough diagnostic double checking everything making sure the rest of the unit was good. A short time later lines where vacuumed, new refrigerant was added and my AC was up and running cold. Thank you Cytech for stepping up to the plate and hitting a home run. If any problems come up again you'll be the one I call.”

“Outstanding service and professionalism. Our AC went down and Cytech was able to send a technician to us within a few hours. Had our AC running back in no time. Will call them again in case of emergency. We have also used Cytech for our semi annual maintenance of our HVAC. It is definitely worth the investment.”
