My wife and I were in the market to replace a residential 2001 vintage(12 year old) Rheem Seer 12 Scroll 3 tonne air conditioner. This replacement was being done proactively for several reasons: 12 year old age of system, system was noisy inside the house due to the nature of he air flow and installation configuration, Spring time often has manufacturer discounts, we wanted this done before the summer heat, another Rheem unit failed last year before i had a chance to change it out proactively. Over a period of several months of research we had decided to purchase a Lennox seer 21 system. At that point I wrote up my specifications and found 3 Lennox dealers all who came out to our house, reviewed the situation, and supplied a quote. Two contractors supplied we felt fair and well thought out quotes. The 3rd contractor was from "Mars". At that point Advanced Air Systems jumped into the favored status because they were low bid after the other contractor could not lower the price.
Then came the installation which in our case was a 2 part effort. Removal of the old system was phase 1, after which I rebuilt the interior closet space, followed a week later with the install. Since this work was performed in the spring weather of Fort Lauderdale, the A/C absence for a week was no problem. Two men worked a full day to do the install and 4 men came the next morning to complete the install which I suspect Donnie the supervisor felt was running long. I was interacting with the install team to be sure my requirements were met, so I may have extended the system install time. But the install team handled my interruptions without fan fair and a can do attitude. I am giving a rating of 5 stars to Advanced Air of Fort Lauderdale, and 5 stars to the Lennox 21 seer system installed. We are totally satisfied with AA. I hope management over there at AA can keep the team performance this high consistently, no easy task I suspect in the A/C contractors business.
