In short, do NOT hire this company or "Achinache Services", which they may have changed their name to. The end result of a very long story (below in case it helps anyone else) is that we paid Auchinache in full for the job, have had our unit about one year, and just had to pay another company $500 to reconfigure duct work and add a filter. Yes - a filter - basic. They did not configure duct work to allow for a filter that is 100% needed for the proper functioning of the system. The process of even getting them to finish the job in a decent way however, was the single worst professional experience in owning and renovating our house over the past 16 years, and end of day, they are simply not competent... Long story...we hired Auchinanche for this job because we had recently had good experience with their plumbing services, and knowingly were paying a high price for what we thought would be great service. However, upon install, there was MAJOR mistake after mistake caught by either us (homeowner) or our contractor. These included huge gaps in duct work - multiple times, failing to link the drain plug from the system into drainage OUTSIDE the house, instead drilling half way through the brand new foundation and stopping. Luckily, our contractor caught this one, but even so, they didn't even hook the drainage up correctly on the unit, so it ended up draining straight into our drop ceiling anyway. Again, pretty basic. On another occasion, the service guy handling hooking up the electric for the unit completely trashed our downstairs, knocking down clothing in laundry room, stepping all over it with muddy boots - you get the idea. complete disrespect of property (this is not an all inclusive list). Now, how did the company respond? As we complained with each instance, they DID respond. Offered to pay for dry cleaning, changed up the incompetent service techs for others, sent the LG reps for the unit out to consult on duct placement, replaced the drop ceiling, and at the end of the day refunded us $256 which was the amount our first service would cost (per VP - see below). This was a process that took us serious time and stress to manage, so I worked my way through the 'complaining' food chain up to the VP, Chris (who has only responded to one of many negative reviews on Angie's list). This is where I caution anyone reasonably considering going with them stop and pause. I spent almost 90 minutes conversing with Chris, during which time he claimed 'they would have caught their mistakes' and that if I (homeowner) hadn't try to manage their processes, they would have figured everything out themselves (all evidence to the contrary). This, even after he shared he himself reviews photos of the jobs daily. Since this was obviously getting me nowhere reasonable, I just stated to him that I felt since we had so many errors and inconvenience in this job, I wanted him to reduce our invoice amount - to which he said "I have never had a customer ask for financial compensation for their time and effort". This is laughable seeing that the only post on this site he responded to, he acknowledged he reduced a bill by $200....in 2014. In a nutshell, quality not there, and leadership that would rather argue that they fixed each issue instead of acknowledging these issues should never have happened to begin with considering the caliber of company they claim to be. Unfortunately, this overrides the very few good techs that popped in and out of the job here and there who clearly were frustrated and trying to do the right thing by us. We considered sending them our 500$ invoice we just incurred, but knowing the level of service, it's not worth the time. Hope this helps someone else avoid the same situation, as much in frustration as in cost.
