    -Install Gas Flex with Safety Shut Off Ball Valve at new furnace
    -Install Sediment Trap on Gas Line prior to new Shut Off Ball Valve
    -Install Plastic Pad under new condenser to ensure proper drainage
    -Install Earthquake Brackets securing new condenser to plastic pad
    -Install Fusible Power Disconnect and Electrical Whip at new condenser
    -Seal and Insulate all exposed sheet metal and connection points
    -Flush existing refrigerant lines to accommodate new R-410a Refrigerant
    -Pressurize existing refrigerant lines with nitrogen to test for leaks and remove moisture
    -Pull vacuum on refrigerant lines and evaporator coil to remove all non-condensibles
    -Charge system with R-410a Refrigerant using Superheat and Subcool calculations
    -Test equipment to ensure proper operation
    .
    .
    RELOCATE FURNACE:

    That sounds about right. I've been quoted at about $2300 to $2800 to replace just one of our outdoor units that has a leak that can't be repaired. You've got at least 4 times that amount of work.

    Yeah, that was about the cost of having my entire ductwork redone and a new American Standard unit placed at my house.

    That's a really good price for Orange County, especially considering the new HERS regulations etc. Figure the HERS test and permits will add about $500-$1,000 on top of that bid depending on what's required in your area.

    If you are comfortable with that contractor, I'd be comfortable with that price.

    Asbestos is only a issue if air born. Don't cut the insulation and you won't have an issue. Much like lead paint, don't sand through the 5 layers on the wall and you'll never get lead poisoning.

    The ducts are still intact although there is a lot of air leak from the furnace to air ducts. I've have been getting high electricity bills when I use the AC especially during summer time.

    Contractor seems honest gave us an option to keep the old ac equipment and just do the duct work. But if we decide to change out the equipment in the future and move the furnace at the attic we have to redo the duct work again.

    In a 1000 sq. ft. Home, we got a new system (inside and outside units) with using existing ductwork, not relocated for $5000

    Sounds like you are on par. The big chunk of dough stings at first, but the difference will be worth it when you are sitting in a quiet and comfy home watching your energy bills drop.

    Do you have modern/updated windows?

    Just spent $12K for a top-of-the-line Trane system and new ductwork.
    So yeah.
    Not cheap, but what a difference.

    That doesn't seem too bad.
    We're a local HVAC company, if you'd like a second bid I'd be more than happy to send our salesguy over. Not trying to solicit any work, we're (thankfully) very busy just trying to help out a fellow TGP'er!
