New A/C: Help with determining fair replacement cost

kck · 2006-01-19T20:27:40+00:00

Hi, this is my first post so please excuse my lack of knowledge...Ihave a 10-year old home with builder grade Lennox, 10 SEER. 2-ton unitdownstairs, 2.5 upstairs. Over the last 2-3 summers, the downstairsunit has needed refrigerant and the last guy here determined the evapcoil has a leak.The same outfit estimated some items today and as I am very new at thisI wanted to try and get some advice, and also ask if these prices arein line. I am in the Atlanta, GA area.My choices:1) Replace evaporator coil only with like unit, $9502) Replace evap coil (upgrade 2 ton to 3 ton) plus replace externalunit, all taxes, materials, etc, upgrade the 2 ton outside to 2.5 ton(I think I need this as have never been happy with the power) : $2700.Parts will be Lennox, 11 SEER (13 SEER is about $1000 more so amthinking this will do as it is is till an upgrade from 10).Should I get more quotes? Or is this a pretty fair figure? The companycomes recommended from a neighbor who has been in the constructionbusiness (but is not affiliated).PS Had posted this to alt.hvac and was advised to try this forum.Thanks all!

Count all the doors in your home and divide by 7. Your answer will be how many tons of cooling you will need. Bubba

Wrong, you have to then multiply that number by the number of door frames and then add in the number of piles on he carpet then multiply all that by pi.

Interesting.

If I invite a friend to spend the night, the house will grow an extra door.

I always tell my friends that if they want to spend the night, they have to bring a door.

I don't get much company......
