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.

Horrible service to get scheduling. Finally a time was set for Friday between 4-6pm. I made sure I was available at that time by leaving work early. Cytech never arrived. I get a phone call a little after 7pm apologizing that they were running late and would be there within 15 minutes. I told them that would not work since I had dinner plans with my wife for 730pm. They insisted they were really close by. I became really upset (but calm) at the insistence and lectured them how I had waited for them for hours and sacrificed several hundred dollars in two billable hours by leaving work early. They apologized and insisted they had a tech ready to be at my home right away. I broke it down to them that it was not going to happen. I told them I expected them to show up tomorrow morning. The manager wouldn't allow it because it was only for "emergency calls". To shorten the story, they would not budge on the Saturday visit. I cautioned them that I would be leaving accurately poor reviews on Angie's List, Yelp, and all other reviewing sites to warn as may people as possible. Overall: I assume their techs are good, but their Customer Service is worthless! I will not do business with a company that cannot keep their word. It makes me upset thinking about how many other people they probably do this to on a daily basis; people who miss work and may not be able to afford it. I would hate to take them to Justice Court (aka "small claims") for their breach of contract as well as other cause of action, however, I'm blessed to have earned a law degree, so I am strongly contemplating moving forward with it so they can learn to respect their agreements and other people's time. I will pray on it.
Response from Cytech Heating & Cooling L C

"I again would like to apologize to Mr [Member Name Removed] that he did not have a good experience with our staff. To explain a few things I would like to start with the fact that we do not give out exact appointment times. We strive to do our best the first time we are at a residence and some times this calls for the technician to be there longer than expected. So we usually say afternoon or morning or something like "after 4pm". We advise we will call when we have a technician available so that the customer can meet us so there is not too much of a disruption of their schedule. We value ALL of our customers time and try our best to take care of everyone as quickly and efficiently as possible without reducing the level of service. We tried to do the visit that day even though it was later than what he expected. The service he purchased is only for regular business hours. It is stated clearly on the Angie's List website as such. Even Mr [Member Name Removed] himself notes how many times we apologized for the delay and tried to get the service completed. Unfortunately that did not work with his schedule. Therefore I am glad he received a prompt refund for all fees he paid."

In the past if they sent someone out they stayed til the problem was fixed = this time they sent someone out = didn't tell us til after they charged us $75 that they couldn't do anything til 6 days later.  We are both over 60 years old and care for several animals that are over 10 years old and are kept inside.  My husband told the guy when he left that we would never use them again.  For that reason I can't give them a good review.  They could have told us when we stopped by their office that they weren't available that day.  Since in the past if they sent someone out they only sent them out if they could repair the problem that day, we were under the assumption they were available to repair the problem.  We have also heard nothing from them since they left.  WE are not new customers = we have used them for years but their attitude that day was horrible.  We live in a mobile home and it is in the 90's outside.
Response from Cytech Heating & Cooling L C

"I can only apologize to the [Member Name Removed]'s for the way this was handled. We strive to never leave anyone not cooling. Unfortunately this summer with over 80 days over 100 degrees has us and I assume most other air conditioning companies stretched thin. When we normally diagnose a coil clean we usually do set it up for another day as that job takes multiple hours and sometimes multiple technicians to perform. Even in the past for the [Member Name Removed]'s we set up their coil cleans for days other than the original day it was recommended. I cannot say for sure at this point if the wait was six days, but being it was a Friday call I can see it would have rolled over to the next week, which is less than ideal. As for us not calling them back to schedule it was made clear to our technician that they would call us to schedule. We are not perfect but we do strive to take care of all our customers to the best of our ability and in this instance we did not live up to our own standards of quality care."

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.
