Their salesperson that we dealt with (Steve?) was very friendly and down-to-Earth. He addressed our concerns that many other companies steered clear of about whether or not it'd be worth completing an energy audit for a 2nd time or not in this home (for us, it didn't make sense to do it again because we don't have a second project left that we could do that'd increase efficiency). Their final pricing was also $4000 less than other competitors partially because we were on the border line of needing a large a.c. unit and after explaining the advantages and disadvantages of each size, we went with the smaller unit; this option wasn't offered to us by other companies.
We have lived with the purchase for almost a week now and are happy with it. It's considerably quieter than our old unit and cools the house much more quickly than our old unit. They were able to accommodate our work schedule in terms of times to meet for estimates, measurements, and starting the install.
Only giving them 4/5 stars in terms of satisfaction as they didn't really clean up much after themselves and when they did, they used our own cleaning supplies and then didn't put them back where they found them. Our two brooms had been used, and we think our Shopvac as well. Even despite all that, there were screws and nails all over the place that took a long time to clean up.
They were also anticipating that they would be done around 3:30 on the install day, so I arrived home around 2:30 to meet them, but they called along the way that they were done. They said everything went well and there were no concerns. When I arrived home though, the house smelled so bad I had to call them back to find out why and wait in the backyard (the smell was that strong). Turns out there was oil on the coils that had to burn off, and that the fumes were originally so bad they set off our fire/carbon monoxide detector. So the smell was from that and the adhesives used... Would have been nice if that was stated as something to inspect instead of "everything is great and nothing went wrong!" To their credit, they did return to inspect/explain this in person within an hour. When they returned, I also asked that they finish repairing the duct insulation that was hanging off of the duct work. I anticipated that they'd have to dismantle it to work around it, but expected that they would have put it back when complete instead of leaving it for us to deal with.
Overall, relatively happy with the experience, but an extra 15 minutes of care at the end of the day would have gone a long way for my overall impression of them.
