Cleaning all the ductwork is an additional $1200. The house is 3400 sq ft and was built in 1988. The units have a lifetime guarantee. I was kind of stunned at the price. (We live in the south and AC is a must). Does anybody know if I am being taken for a ride on these prices? 10,427 posts, read 37,316,391 times 8,923 posts, read 33,173,370 times 1,940 posts, read 6,665,304 times Could be you don't actually need that much A/C 4,516 posts, read 17,060,880 times 5,502 posts, read 10,136,839 times Originally Posted by vicket What brand are the units? Obviously Carrier or Trane is going to cost more than big-box-special low-end Goodman. So your estimate is for 2 new air handlers, a media filter on each, 2 new condensers, and 2 new thermostats -- right? In other words everything but the ductwork.

Cost will vary greatly depending on where you live. Here on Long Island, back in late 2002, the complete new install (ductwork, etc) of a 3-ton and a 5-ton Carrier Puron system with AprilAire filtration cost me just under $22,000 for the entire thing. And that was a competitive price, and an approximately 4500 sf house. I'm certain the same system would cost much more than 22K hereabouts nowadays. 4,508 posts, read 6,652,806 times Angie's List Answers is the trusted spot to ask home improvement and health questions and get answers from service companies, health providers and consumers.

Unit is about 20 years old and mounted on the roof with duct work in the attic.ac and heating window unit I just replaced one last month in California an the total cost to the customer was $250.00 For parts + tax and $150.00 Labor. 4 ton home ac unitA 20 year old unit in Southern California weather has lived a useful life. central ac sizing chartYou should be preparing to replace the unit in the near future. If it's a "package unit" it has an indoor and an outdoor motor. The indoor, could be between $450 to $700, the outdoor between $350 to $500, here in Florida.

If it's a "split system" it has only an outdoor motor,so same as above.20 years is a long time, other failures could be in the naer future , I'd think about replacing and reducing my electric costs, as a lot more effiecent units are made today, then 20 years ago.Saving hunderds per year in operating costs, is wiser investment. What would the installation cost be for a new Gas Furnace and HVAC unit if we purchased our own equipment? How much to replace an indoor ac fan motor for 6 ton carrier roof top 7 years old? I have a 4 ton York A/C that the technician today mentioned it needs a new Blower motor; The unit is 10 years old, How much should a standard height, 42 inch convector unit cost to replace in Washington, DC?Sorry to veer off topic a bit, is it common back east for houses built - say after early 70s - to not have forced air heating?I have only worked in the west and only homes I have experienced with no ducts were built in 50s / 60s or before.said by Liberty:Sorry to veer off topic a bit, is it common back east for houses built - say after early 70s - to not have forced air heating?

I have only worked in the west and only homes I have experienced with no ducts were built in 50s / 60s or before.I think that baseboard hydronic heat was considered a premium upgrade and people bought it to reduce drafts, noise, dust, etc. They likely never had plans for central air, that was a LOT less common in that era so provision for it wouldn't have been a consideration. These days most people want central air, or at least to have the option to install it later, so forced air heating is a natural. They estimated about $16,000, and my mother thought it was an outrageous price. (I beg to differ, considering we have NO ductwork at all!). What does anyone else think? House is about 1700 sq. ft. and they would install a 2 ton unit. Not vents in the lower level, just upper.said by pjsutton:They estimated about $16,000, and my mother thought it was an outrageous price. Not vents in the lower level, just upper.That price is outrageous For a 2 ton unit? its a Ripoff i got a 3ton 2 stage 16 Seer heat-pump had duct-work installed etc for 8-9K,My Brother had a existing unit the same unit for him $6890....My house is 1700SQ its 3 ton 2 ton wont cool it thats way undersized.

Have you looked in to High Velocity AC? That's what we have. We had no room to add ducts and it's worked out very well for us for 12 years.»The guy said it was better to err on the side of 2 tons for optimal efficiency, said a larger unit would run less and cause it to be less comfortable, more humid, etc.said by pjsutton:Interesting. The guy said it was better to err on the side of 2 tons for optimal efficiency, said a larger unit would run less and cause it to be less comfortable, more humid, etc.Did he also mention that he makes money on service calls when you complain that you're sweating inside on a hot day? Or that in order for the house to be comfortable at 5PM you have to run the A/C literally all day, thus negating all the savings and then some? Or that a variable speed air handler takes care of all humidity? What about the fact that the longer it runs per day the sooner it will have to be replaced?You don't want to grossly oversize - and a dual stage or variable speed unit will insure that, as it will run on the lower speed as long as it can handle the load.

to pjsuttonsaid by pjsutton:He actually mentioned that if we raise the temp 5 degrees when we aren't home it would only take an hour or two to cool it back down. I don't believe that at all. My dad has central air and going down 5 degrees would take several hours (but his system was installed cheaply by the condo contractor 30 years ago).That is undersized for sure. Many companies will claim as small as possible tons will be the most efficient but in real life it means you can't cool the place down. Depends on your windows, doors, insulation etc. Also the amount of people in the house along with how often the doors will be opening.If undersized this is what happens. With all the windows covered and no one goes in or out and there aren't many people in the house then you're fine. Don't want to live in a cave, have friends and pets??? Forget about it, you'll never cool the place down to after bed time. Forget about not running the AC during the day, you'll never cool it down when you get home.
