Alco appliances was very responsive, knowledgable, and friendly - overall easy to work with. Our gas oven had been leaking gas just while the oven was on. It was easy to schedule an appointment and Alco came right out to look at the oven. The problem was diagnosed as two possible issues, either the safety valve or the thermostat. The technician recommended replacing the oven (as did the owner), but did say that a repair would extend the life of the appliance, which is really all I wanted. Both the technician and the owner were willing to go over our options and helped us make the decision. Unfortunately, the technician did not have the parts and had to order them and return to fix the problem. This was a minor inconvenience since it requires taking time off work to be in the apartment, but even with having the oven model number in advance I'm sure it's not possible to stock all parts all the time. Alco came back out at a time that was convenient for us, and made the repair. Only the safety valve needed to be replaced and the part that was not needed was returned at no cost to us. The only hiccup came when our tenant returned to the apartment on a Sat. after several days of being away and smelled a strong odor of gas. Washington Gas came out and turned off the gas line to the stove, and Alco returned the next business day to take a look. The assessment was a pilot light had gone out, normally not big deal - but with no one in the apartment for four days over the holiday - the smell built up. They rechecked the work that had been done the previous week, and stuck around to make sure the pilot stayed on. I was very pleased that Alco was so responsive, and both the technician and the owner answered our Sat. phone calls about the issue.
