"Maynor replaced one of our AC units. This installation by Sergio, Austin, and Marcus was done quickly, efficiently, and professionally. I highly recommend Maynor for their service."

"Derrick checked the whole unit and identified parts to be replaced. He was very professional and knowledgeable"

"It went well. They have ordered a part and will come back to replace the piece."

"Removed old hot water tank and replaced it with a tankless hot water heater. Work was done in crawl space with less than six feet height available in work area. All done in a few hours last September. It's now the following August (11 months or so later). Everything seems to be working okay. Workmen were polite, professional, timely, focused on the job, carried away all the old parts and cleaned up well---we were quite pleased with the whole process."

"In summary: They were - Friendly - Accommodating - Error prone, both in installation and in documentation. - Willing to work until they finally got issues fully resolved. More detail below: Eventually, with enough effort on my part, I think I got a good installation with an accurate invoice. I believe that they were interested in providing a good installation. But there were many errors along the way which only I caught so that they could be corrected, both with the installation and the invoice. They were extremely friendly and easy to work with. I, like many engineers, research systems like these before starting the quoting process. So I knew enough to know many of the items to watch for to ensure a quality installation. For instance, when their technician came out to do the quote, I asked if the following things would be done: 1) Flush the existing coolant lines to clean them out, 2) Check the CFM (cubic feet per minute of airflow), and 3) When brazing the copper supply lines, would they flood them internally with nitrogen to eliminate oxidation, which can cause reliability problems years later. The answer to all three of these was yes. However, at installation, 1) They did not flush the coolant lines. Later they told me that Carrier advises against it, which is fine. But why their technician say that they would do it? 2) They did not check the CFM, until after a couple of later requests from me to do it on a return visit. 3) Their technicians did not plan on brazing with nitrogen even though they had a tank of nitrogen with them. They said that they didn’t even know how to do a complete nitrogen braze, which means that they had been installing HVAC systems without doing it for years. I wonder about the reliability of those other installations. Eventually, another technician with more training arrived and showed them how to do it. In addition, during the installation, they did not level the compressor correctly until I pointed it out to them. They later fixed this. The first thermostat they installed was a nice one, but it was wired incorrectly. I found this and reported it to them. Also, it was the wrong type. It did not have a way to activate the HVAC’s special feature to reduce humidity beyond that which a typical system does. I paid quite a bit more for a system which had this feature, but unless I had noticed this, I never would have gotten it. They came out and replaced the thermostat with another thermostat with the humidity control feature. But for whatever reason, when it thought it was time to reduce the humidity, it just turned on the blower, which does nothing to reduce humidity. I found that neither of the first two thermostats was the more expensive one which Carrier recommended as part of the installation. I reported this to them, and they then came out to install the third thermostat which finally got things working right. They did not charge me anything for the more expensive thermostat. It took 5 different invoices from them before I got one which had no errors in it. Problems included: no factory rebate included, factory rebate added, rather than subtracted from price, wrong equipment listed, and wrong serial numbers. I caught all of these problems and had them fixed. They also found that they had to change the thermostat model on one of the revisions of the invoice. This worked to my benefit as the changed thermostat model increased my factory rebate considerably. Finally, after paying them, they did not send out a receipt showing that I had paid them, even though I was told that I would get one by email. After not getting it, they simply took the final invoice, and hand-wrote on it that it was paid, the amount, the date, and the name of the person who wrote this by hand. They scanned it and emailed it to me. When I asked if there was not a more formal receipt, they said that this is all they supply for those who ask for payment documentation. Again, I think their heart was in the right place. When there was an error found, they did everything they could to make it right. But it was generally me, not them, who found the errors. I am not an HVAC expert, but still found the issues. They were generally quite friendly to work with."
