My tenants complained that the heater is somewhat noisy. Is that something you can look at? Part of the house is a central heating unit, while one room is a wall heater.

Before I give you a schedule, let me tell you how we work here. For our technician to come out and do a full diagnostic, we have a service call fee. The fee will be waived once you proceed with our repairs. Unfortunately, we are fully booked for this week, so the soonest schedule we can give will be Monday next week. If that's okay for you, I can schedule an appointment for that date.
