"We picked Cytech from a listed of recommended AC contractors on Angie's List.  They did have to competitively bid against another contractor.

We worked with CyTech (Leo Cantu) for a couple of weeks hammering out the scope and details for the ac replacement.  They were extremely professional and easy to work with, given the fact that we were developing the proposal remotely (me in  the New Orleans area and CyTech in Edinburg Texas).  They answered all our questions and went the extra step to ensure that we could use the updated electrical system by having the owner personally come to our house and  look at the configuration. They even recommended a LOWER tonnage AC unit after their visit, saving us hundreds of dollars from the previous estimate.

The job itself started on Monday and the crew  performed very well all the while being courteous to my mother.  The crew worked into the evening of the second day to ensure that a minimally operational AC unit was available  to provide  cooled, dehumidified air,  delivered through a few selected vents including the bedrooms.   That was real commitment by CyTech to ensure they wouldn't have to go through another hot humid night.   They completed the balance of the work, including a new duct system by late Wednesday afternoon.

We did have a bit of a concern when looking at the outside condensing unit, based on the dimensions we measured.  I was sure that we did not have the correct unit.   The system was shorter that we had thought, and was definitely shorter than listed in the Lennox literature on the Lennox webpage.  

After Leo followed up, consulting with the owner, we were told that they had installed the latest Lennox unit. The reduced height was the result of incorporating a two deep evaporator coil system, maintaining the radiating surface area, but lowering the height f the unit.    My sister went outside and spoke with the crew. They showed her the new design; I felt much better after that confirmation.

The unit has been operating for just three days, but it has been fantastic.  I especially love the Wi-Fi thermostat that was installed with the unit.  I can see, from here in the New Orleans area, the current status of the unit, the temperature and indoor humidity.  We can change the setpoints from our iPhones!!!...how much fun is that.

I have asked them to proceed to add blown in insulation to the attic documented in a separate proposal.  That work will be done after some minor repairs (shingle replacements) are completed on my mother's house roof.

Five stars rating to CyTech.

"I used the Neli service, where the tech connects with you via video chat and then walks you through troubleshooting and repair. I’m pretty handy so this seemed like a route that would work for me. Once we got connected we got right to work and figured out what the issue was and how to repair it. I had to run to hardware store to get the correct tool to make the fix, but Bob, the tech I worked with, left me detailed instructions and with the right tool, I was then able to make the fix and reassemble the range. It works like a charm!!"

"I was impressed by their professionalism and customer service. They arrived prepared, solved the issue quickly, and left the area clean. I would gladly recommend them to family and friends."

"Very happy with the work done. Found more damage after work started but Medina Brothers gave me a price and repaired everything on time. Replaced"

"I contacted Angels cooling, due to my a/c had stopped working. I found out my system was way too old and not worth the repair. I got a system replacement that same week. Thank you Angels cooling!"
