The phone number on this site is Don’s. When you call or send a request, you are dealing with Don himself.
Tell him what the equipment is, roughly how old it is, and what it is or is not doing. That is usually enough to start the conversation.
Ask Don to explain what he finds and what your options are before any work goes ahead, and ask whether he serves your area.
If your heating, cooling or hot water needs attention, call Don directly or send a short request describing the problem.
