My wife and I upgraded our 2 a/c units in our house, as they were nearly 30 years old. I looked at vendors recommended on the Austin Energy web site and called one. The salesman offered two solutions, both using the old freon type, saying that the freon would be available for 20 more years, and the new freon was unproven and more expensive. My wife and I are pro-environment, and did not want the old freon. Research at hvac-talk showed that as long as the lines were correclty purged, the new freon was better, and that the cost of the old freon is already more than the new freon. Also, the vendor sold Trane, which is over-priced in my opinion. I called a contractor I had worked with once, who quoted Amana. I had not heard Amana made A/C units. They have a lifetime compressor warrantee, and 10 years on the rest of the system. They have stainless steel tubing, and over-pressure protection (whcih Trane does not have). They do not use proprietary parts (like Trane), and they also were one of the first to use the scroll compressor, now used everywhere. That quote was only $1000 less than the Trane, which did not match what I read on-line.
I then saw Austin Air Dynamics at the Amana web site. I saw glowing reviews at CitySearch, so I asked for a quote for both 15 SEER and 16 SEER 2-stage Amana units. The price installed was thousands less than the other quotes. And the price difference for the 16 SEER was paid for by the city rebates! It is a 2-stage system, which I also recommend (higher SEER on low).
Luke was very professional, and his crew did a stellar job. I put down cardboard to protect my new wood floors, which I recommend to anyone. The crew did not damage anything, and the installation was trouble-free (in a very small space). Luke applied for the city rebate, which arrived on schedule. He even called to make sure I received it!
In summary, a professional installation with excellent customer service at an unbeatable price.
Pros: Professional, Friendly, Great Price; Punctual; Good Follow Up; Great Service
