    I'm stuck on " Reconnect existing ducts and drain lines
    Insulate the main drain line in the attic"

    Mentions drain pan also? Does that mean your unit never had one ( aux. drain pan under AH ) and they need to disconnect the ducts to elevate the AH then install one ( aux. drain pan ) and drop AH back to normal position and reconnect existing ducts and drain line?



    Certainly a mismatched system if only changing the OD section, you may have a 10-12 SEER indoor coil to a 14 SEER outdoor coil, will it work, sure, may not be the most efficient.

    If you go with a indoor unit make sure it's a AHRI matched system for optimal performance.

    Ask them for this, if going with a replacement ID unit. This is only an example of what they look like.

    Goodman already puts a filter drier inside the OD unit, so there really is not a necessity to have a field install one.

    What's the labor and manufacturer parts warranty they are going to give you?

    Who's going to register your system?

    Here's what the quote says about warranty: "The new systems will be A Goodman brand 14Seer system Seasonal
    Energy Efficiency Ratio, new systems comes with 10 years part warranty. We also honor a one year labor free warranty to ensure that the new system can and will operate smoothly and trouble free throughout all four seasons."

    The quote doesn't break things down between parts and labor. Is that typical?

    Totally normal to get a straight up price on a replacement and not broken down any farther then that.

    Still doesn't answer the question if they are replacing the indoor Air Handler or even just the coil. Make sure they give you a copy of your 10 year compressor and parts warranty.

    Again if they actually do replace the ID coil or Air Handler ask for the AHRI reference number, like the example sent to prove a match.

    Update: I got a new quote from another contractor who said the air handler/coil unit did not need to be replaced. This was the contractor who made repairs to the system for the previous homeowner. He pulled the records and saw the air handler/coil was replaced in 2006 with a unit that can work with R-410a. He did not think the pad, drain pan and thermostat needed replacing and came in with a quote for a larger tonnage A/C unit at a lower cost. Right now we're inclined to take that offer.

    NO! Do not install a larger unit! That is NOT an upgrade! It is highly unlikely that the duct system is big enough even for the old equipment. Undersized ducts will saddle you with a noisy, inefficient system for the shortened life of the equipment.

    A larger tonnage unit is not an upgrade of any kind, regardless of cost.
    You only need what the load calculation says you need.
    The metering device in the air handler still needs to be changed.

    Actually, the existing R-22 A/C unit is a 3-ton. I was wrong about the size of the unit and the first contractor didn't confirm the size when he wrote the quote (he made the original service call, so he should have quoted the price at replacement for existing size). The second contractor I contacted (not affiliated with our homeowner's warranty) had replaced the inside coil in 2006 and confirmed it will work with R-410a if he replaces the regulator(?). He didn't not think we needed any of the other (new pad, new liner, new programmable thermostat). His price came in much lower than the first quote. I'm inclined to go with this company since they installed and worked on our system with the previous homeowner and knew exactly when previous repairs had been made and what equipment currently exists.

    So you have a 3 ton now and they are proposing another 3 ton?

    Why not just replace the compressor and put in an R-22 replacement like R407C? Changing the equipment is the best bet in the long run, but life isn’t always convenient like that. Other parts could break down the road not under warranty, but when every dollar counts that’s likely the least costly route, and we do it everyday for customers

    No one gave us that option--this is the first I've heard of it. Thanks for sharing.
