    I am new to this forum so advice is appreciated.

    Getting quotes for a two story house around 2200 square feet.

    Recommendations are all for a 4 ton AC unit with new duct work and new furnace. Very expensive to say the least!

    I'm in Arcadia, CA 91006.

    1. Has anyone heard of Comfort Climate Control in Azusa?

    2. Is it really that much better to get variable speed rather than single speed?

    3. Any other good AC specialists in my area that I should know about?

    For what it is worth:

    Since this is California I believe a "heat gain / loss" calculation is required to insure the correct sizing of the HVAC system. Make sure you get one.

    Personally I would suggest a (2) system install instead of one 4 ton system unless they are installing a zoning system. Otherwise you will never get even cooling or heating in this setup. 4 tons sounds a bit much but then again I know nothing about your climate or the insulating qualities of your home. Good luck.

    SoCal is a funny market for AC, finding a good contractor may take some patience. Arcadia as I remember gets nasty in summer, the inversion effects.

    The pros here are big fans of doing a manual J to size the system, I tend to wonder about how well the existing system does when its working ok.

    From what I hear the cool weather has been holding off the big summer AC rush a "bit", but it may have kicked off during the last week. If you "need" AC you need AC, but paying through the nose is going to be part of it, best you can hope for a very busy contractor that is willing to work for a fair price, good luck finding one.

    Don't contradict what us pros say about Manual J. I've about had it with your comments, they aren't valid. Time for the mods to step in on this.

    1. No.
    Did they mention heat pumps?
    Did they mention life cycle cost evaluation?

    2. Yes.
    3. No, it does not take a 'specialist' to install A/C.
    It takes Experience and knowledge.

    How old is your house?
    Does it have adequate insulation?

    Do you have any windows? How many?
    Do the windows facing west have tinting?
    Just a minimal start ...

    Easy Seaton. He states the pros are big fans of Manual J's, which I agree totally. He's not, get it? If someone wants to risk a large sum of money without doing a load calc, that's fine. Just don't complain later if it's capacity doesn't work.

    Ya, but there is more to it than just capacity, we all know this. What the previous system did(yes, I'm harping on things that have been said a million times on here) doesn't matter. Did it cool the house, yes...but how efficiently?

    My house is old (>50 years) and has poor insulation and lots of single layer glass. 6 west facing windows without tinting.

    Arcadia routinely has 100 degree temps in the summer.

    It gets terribly hot in the second floor because Arcadia is damn hot in the summer. the upstairs is around 90 degrees in the summer with the current AC on full blast.

    They recommneded at Trane XL14i and XT80. the price difference with the XL19i is at least XXXX dollars.

    also, these guys are through Home Depot which was slightly cheaper than Sears.

    It never ceases to amaze me that homeowners think companies install equipment. People install equipment. Did you get the right person is the question you need to be asking.

    Tint the windows, especially ones facing West

    Besides doing all the good work of Manual J calculation and size the system properly. Check the New calc against your current system strictly for comparison purpose, as your current system may be oversized and therefore, a smaller unit (and less expensive) can do the same job.

    TINT your windows, either DIY (cost of film + your labor) or have a professional do it.

    TINTING saves me big buck already.
    - Last year May 2005: electricity bill $150/month (5500 SF home)
    - This year May 2006: $100/month (with windows tinted 2 months ago).

    Hope this helps.
