Will be moving into a 30 year old split level house outside of Boston. Looks like I will have to replace the existing heating furnace.
Presently, the house has a gas, forced hot air furnace, with a section for the condenser part of an A/C as part of the duct work exiting the furnace.
Would like to know a bit more about the state-of-the-art in these things before going to a contractor for an estimate.
a. Are there different types available these days ?
Pros and cons for the differences ? Recommendations ?
b. Is there any consensus regarding the "best" brand(s) ?
Probably more important, and brands to avoid ?
c. How does one size for the appropriate unit ?
d. Not really too sure what else to ask.
Any bells and whistles that I would want to consider ?
What should I be asking the contractor specifically about ?
Any opinions and thoughts would be most appreciated.
