This was our annual maintenance check up, part of a monthly plan through Aire One. We made our appointment when services were made available following Covid shut down. Aire One confirmed the appointment, and the technician’s expected arrival time, the afternoon before our appointment. Vahid arrived on time. He was polite, followed social distancing protocol, and was efficient in completing his work (he even removed and left his shoes on the stoop). He inspected the furnace, ventilation and air conditioning in a timely, careful manner. He seems knowledgeable, and he thorough.
