Very well. Another reputable company who had been in business for 40 years could not figure out why my master bedroom was always 4-5 degrees hotter than the rest of home. They blamed it on several factors which was incorrect . This company immediately knew what needed to be done by doing an air balancing and now my master bedroom is as cool as the rest of the house. I decided to buy a new unit also , which had nothing to do with the cooling problem in the master bedroom. I would call them again if I need too.

Great! They couldn't replace our system right away, so they sent the repairman who spent three to four hours installing a temporary air conditioner so we would be comfortable. They also financed the purchase of our new system. They have all been wonderful at Cytec.

From beginning to end the process went very smoothly. We started with a service call as the AC was not cooling well. It was found that the unit (outside and in the attic) had to be replaced though there was no pressure. The technician did say he could service the unit and with the service it would probably last a while longer. We decided to replace the system as the units are used year round with the south Texas temperatures are were 13+ years old. The technician was very professional and thorough patching the old system to get us through as the weather was in the 105 degree range all week. The company made an appointment to install the system and arrived as planned. This is very refreshing as we experience many companies who simple do not show up without repeated calls. The two young men who came to complete the install were very professional, cleaned up after themselves and stayed until everything worked as it should. I truly don't know how the two young men were able to complete the task as the temperature was SOOOO hot especially in the attic but work they did. I was very impressed from beginning to end and highly recommend this company.

Employees at Cytech were very courteous and assisted with the scheduling. I had never purchased thru Angie's and didn't know how it worked. The office manager assisted graciously and scheduled the work. The technician stopped by later than expected but I was called before to verify that someone would be home. The technician answered our many questions and made suggestions that would help us in saving on our electricity and maintenance on our AC unit. Additional estimate was scheduled and they were able to meet our timeframes. We are considering getting additional work done by Cytech.

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.

Normally Cytech charges a travel fee for work in Harlingen, but after talking to the friendly office staff, they agreed to waive the fee and instead call me when they had a technician already in Harlingen that could do my service next.  They called later the same day and technician arrive less than 30 minutes later.  He was very professional and did a great job.

Ronnie came out next day and performed the service. Great service very professional, friendly, and thorough. No pressure sales pitches or expensive "recommendations" just a solid System check. I will definitely use them again for my A/C needs. The communications were excellent and Ronnie did a great job of explaining things.
