AHM was bad (I had the district supervisor for Home Depot in my living room, trying to resolve all of the issues connected with the install), then they changed their name and are still bad. I was hard selled into a 5 year maintenance contract a few years ago, they showed up twice a year for the first year then sporadically after that. In 2014 they didn't show up at all, showed up for air conditioning check in February of 2015. I'd have to wait until fall for the heat. Fall never happened. Now it is 2016 and they are calling me to try and salvage the contract. Seeing as their techs have ripped me off more than once (one guy went up on the roof, waited until I was otherwise occupied, then snuck down the ladder and came in the house, going from room to room. He said he had to get something from the truck. I noticed him walking funny and carrying a large bag, which he had not had before. He came back in 30 seconds saying that the part wasn't on the truck. Then I noticed that $6000 worth of gemstones was gone out of my office. The company had fired him [supposedly] already so they took no responsibility) I am thinking to just ditch the contract and get a reputable company. I'd ask for a refund on the unused portion but I'm sure they'd just weasel out of it or agree to it and not do it.. I can't even begin to say how shady these people are. Tempting to get the service (it's been a couple of years) but not sure it's worth it.
