I have a Bryant Plus 90 high efficient gas furnace that is 4 years
old. I change the air filter every 30 days.
I keep getting mailing from area heating companies to do furnace
preventive maintenance for heating and air conditioning.
What questions should I ask about the heating company, to make sure I
am getting a knowledgeable person to do the PM? What will they do for
this type of PM?
How do I know if I am getting a repair person that is trained in the
latest technology of my furnace. Any way to check?
Thanks
