"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 recently had the pleasure of working with Albarado Electric to update my outdoor security lights, and I couldn't be more pleased with the results. David came in and replaced my old, outdated security light with a new, more efficient model. They also installed sensor-activated lights that automatically adjust based on sunrise and sunset, ensuring my property is always well-lit and secure at the right times. David was professional, efficient, and very knowledgeable about the latest lighting technology. The job was completed with minimal disruption, and David always remained in contact with us with the progress of the project. I truly appreciate their attention to detail and quality of work. The new lighting system is working perfectly, and I feel much safer knowing that my outdoor lights will automatically adjust according to the time of day. I highly recommend Albarado Electric for anyone needing electrical work—whether it's for security lights or other projects. They are reliable, trustworthy, and deliver excellent results."

FAQs for electrical wiring or panel upgrade projects in Mcallen, TX

Yes, a licensed electrician is essential for this project. Running an electrical service from the road to your house involves connecting to utility power lines, complying with national and local electrical codes, and safely handling high-voltage systems. 

Licensed professionals understand proper wire sizing, grounding requirements, and voltage drop calculations needed for safe installation. Most jurisdictions require permits and inspections that only certified professionals can obtain. The safety risks and potential for property damage make this project inappropriate for DIY attempts.

Overhead installations are less expensive than underground options. For a 1000-foot run, overhead service costs between $8,000 and $15,000, while underground service ranges from $10,000 to $25,000. 

Overhead lines require less labor and fewer materials since they don't need trenching or conduit. However, underground lines offer better protection from weather events and aesthetic benefits. Your decision should balance your budget constraints with long-term reliability and visual preferences.

You might need to upgrade your electrical panel depending on your power requirements. If your existing panel cannot handle the additional load from the extended service, upgrading to a 200-amp service (costing $750 to $2,000) may be necessary. 

A licensed electrician can evaluate your current system and determine if an upgrade is required. Factors include what you'll be powering at the end of the line, existing electrical demand, and whether voltage drop over the distance will affect performance.

Running electric service from the road to a house requires electrical permits from your local building department, costing between $500 and $2,000 depending on your location. You may also need excavation permits for trenching work if installing an underground service. Your utility company will have its own application process for connecting to its grid. A licensed electrical contractor can handle all the necessary permit applications as part of their service, ensuring your installation meets all local code requirements.
