I was planning to replace my 20-year old gas furnace and air conditioner, and upon doing research learned that Trane is one of the most reliable brands. As an architect, I am particular about this kind of thing. Looking at reviews for local Trane dealers I landed on Able. Greg Grimshaw came out and we reviewed my current system and discussed options. The next morning I had detailed quotes on a half-dozen options, including available rebates and credits; I chose the highest efficiency one which was a heat pump with HE gas furnace for backup.

I was able to get them scheduled for 6 days later and they 2-man crew showed up at 8am joined by a second 2 in the afternoon. They completed the job, which required some duct modifications, by 4pm. Initially there was a problem with the backup heat which was traced to a circuit board which they replaced within 2 days. I am pleased with the system and the installation.

Able only does retrofits, no new construction. They don't ask for payment until they are sure you are happy a couple weeks after the installation. They take care of all the rebate paperwork and it is just deducted from your bill. I am happy to recommend them.
