Not AT ALL a pleasant experience. CANNOT recommend. Go read the NEGATIVE reviews of this company (on Yelp and elsewhere), and you'll notice a pattern. Oh, first off: be careful of leaving a negative review of them on yp.com--you know, like at THEIR (AAC's) website--it might get "disappeared" quicker than a Russian dissident under Putin--like mine did (after being "live" for a day or two). Oh well, so many web review sites, so much copying-and-pasting. In Dec. 2016, my wife called AAC to come have a look at our five-year-old (Navien) tankless water heater. To be clear, the system was not installed by AAC, but another company, now OOB (out of..). After five years of trouble-free service however, its hot water delivery had recently become intermittent and the system would (too) often need to be "reset" (from its control panel) to get hot water again. The "diagnostic code" the control panel displayed usually pointed (in the owner's manual) to a particular component: a "bypass" valve. Also to be extra-clear, this was NOT a OMG-WE'VE-GOT-NO-HOT-WATER situation. Just annoying, really. A once-or-twice-a-week thing, at most. But we wanted it fixed. When AAC came out, they told me that it appeared that not only that valve, but the entire "motherboard" (yes, a computer) would need replacing. But guess what? Turns out (AAC told me) these parts are all under warranty! Yay, right? I tell them to go ahead, get the parts and come install them--and install a "flush kit" that the original contractor should've put on the system anyway as well. It takes a couple of days for one of the parts to be shipped in, but they come back out (two different guys this time), install everything, and hand me--an EIGHT HUNDRED DOLLAR bill. Whoa. To say I was alarmed is putting it mildly. For a mental picture, think of one of those kids' moms on South Park: "Wha-wha-wha-WHAAAT?" But hold on, it gets better. When I balked at the size of the bill, and told them if I'd had any idea BEFORE they started,... (sound familiar?) they gave me the most irritating, insulting part (over the phone): "But, don't you remember that paperwork WE SHOWED YOU on our (the OTHER guy's) first visit...?" Implied: I'm possibly a memory-challenged DOLT, and I'm like, all confused and stuff. "Uh, no ma'am, never saw ANY SUCH THING." If I HAD, I certainly would've said Whisky-Tango-Foxtrot at that point--before parts were ordered and any agreement was made to proceed with the (irreversible, of course) work, etc. Who wouldn't? Bottom line (including, BTW, a HUNDRED AND FORTY DOLLARS AN HOUR FOR LABOR), I gave them the full amount (on my credit card) they got their money, and now...they got their review. I'll bet AAC doesn't remember my telling them I'd be sharing my experience with them on the web. Gotta run--more sites on which to share this. Places where fair, honest, NEGATIVE reviews don't usually get "disappeared," I might add. read more
