I've been using window units for years but I had enough and finally got some estimates for central air conditioning. I had a couple of estimates done both recommended a 2.5 ton setup for my 1200 sq ft home. This is what they had for equipment. The air handler will be in the attic.
These two plans call for 1 return. Rebates make the first option a lot cheaper than the 2nd.
1) 16 SEER Lennox Merit 14ACX condenser with Elite CBX27UH air handler.
2) 16.5 SEER Lennox signature XC17 conditioner with signature CBX40UHV air handler
I also got an estimate with Rheem 16 SEER equipment using 2 returns. No product numbers were given (still waiting for that). Price is about the same as the 16.5 setup above.
How are these two systems? are they comparable assuming both 16+ seer setups are within a couple hundred dollars of eachother?
Is there an advantage to a variable speed fan? Can it really clean the air if kept on?
I dont know what else to ask since i have no experience with central air. Should I push for certain kinds of ducts, dampers, anything like that? My attic is truss and kinda tight. The air handler will go above the garage on one side of the house where its completley open. The ductwork will run about 45ft to the other end of the house (ranch) through the trusses. maybe thats why 2 returns versus 1? Not really sure. Thanks in advance !!
