Here's why I'm asking this: I received a letter from my local Heating/ CentralAC contractor, with whom I have a service contract and already have done business with. The letter said that this is the slow season for them, and that since they have some quality 2004 Central AC systems, and 2004 furnaces, in inventory which they obtained at low prices (and these are fully warranteed units, and not factory seconds or blems) they are making a special offer. They say they have around 72 complete systems in the four most popular sizes, so this is a limited offer.
Basically the deal is supposed to be that if I have one of the new AC units installed in March at a normal price (including installation), then they will "throw in" a brand new furnace at only $999 installed. My understanding is that the total cost for the entire system would be somewhere between $4500 and $6000 for the complete system depending on their determination of the sizes for the new furnace and new AC units. My understanding is that my total savings will by $1800 or more depending on the size of the newly installed units.
I'm located in northern NJ, and currently my townhouse has a 17 year old system with a 17 year old Carrier Furnace and a 17 year old Carrier central AC system (condensor, evaporator coils, etc.).
This offer is intended for homeowners who have 15 yr. old or older systems. They project that those who accept the offer will likely have heating bills and cooling bills that are 30 or 40% lower and have some sort of guarantee that if the heating bills and cooling bills are not 20% lower they will "double my savings" if it is less than 20%. (not sure what they would do if by some fluke my bills were higher rather than lower after the new installation though).
Anyway, they say they would be happy to have a specialist come over and work out the exact numbers, projected savings, etc. for me at no obligation. They don't want to work based on the sizes of my existing units, and prefer to take their own measurements.
Again, they say I'm under now obligation if they send someone over, but my time is valuable. Is this worth pursuing? Would I be better off replacing only when necessary? Is Goodman a quality top tier brand, or not? If not, then what other brands do you recommend.
