You're really not going about this the right way. You would be best off changing both the indoor coil and the outdoor condenser at the same time. The old coil is likely 34 years old too and could be leaking. Putting a 13 SEER condenser on a coil that is rated at around 6-8 SEER is really harming your outdoor unit. Make an investment and don't hurt your new outdoor unit; it needs a matching indoor coil for a warranty and guaranteed performance. R-410a would be a good idea but R-22 will still be available in the future for quite some time. No way should a new indoor coil be adding around $2k to the cost. I don't know why he's quoting so much more--maybe because they'll have to go into the attic? Get everything in writing: warranty, load calculation to guarantee proper sizing, extra parts, etc. New refrigerant lines for a R-410a system would be highly recommended. Good luck. Oh, and I'm not sure if I'd recommend Heil equipment. You'd be getting cheap grade equipment, but if that's all your budget allows, just make sure you're getting a quality installation. I think I'd consider another brand though. Goodman would be on my list if I had limited funds.

Thanks guys, I got a new quote today. Lenox Elite Series XL16 -036-230 Compressor 2 Stage Variable Speed 3 Ton Air Handler Lennox Signature Model # CBX32MV-036-230 Variable Speed Quote: $6,600.00 plus $500.00 Lennox Rebate & $500.00 JCP&L rebate total cost $5,500.00 after rebates. Question, is it more efficient to have a 2 stage compressor in my area as we only use the A/Cfor about 4/1/2 months . The XL17 in my second quote is a single stage in the Signature Series. There is a $1,500.00 difference in the pricing. Also the air handler in the second quote is the top handler in the Signature Series. Your yhougjts would be greayly appreciated.

The price of propane is rising, isn't it? In this case, I'd consider heat pumps that will switch over to propane when the temperature is low enough to warrant the use of propane over the efficient heat pumps (around 35-40* or so). Few matchups will get near the 19-20 SEER range. You need the sizes and full model numbers of the equipment being quoted to know for sure. Trane, Carrier and Bryant all make fine products. If going with Carrier, ask for a tin-plated copper coil (heard of leaking problems with Carrier's *ACA standard copper coils--I guess all mfg's have leak problems). The Infinity/Evolution is a nice system. I personally favor Trane over Carrier--I think Trane's quality is hard to beat, but that's just my opinion. I do wish the XL19i was available in R410A, but that will be a little later. Is your electricity particularly expensive? Going with the top-of-the-line SEER/units may not have a great payback. 20 years old? They've done their time. As far as duct noise goes, if your ductwork is sized correctly, then you should be fine. However, the variable-speed blowers maintain proper CFM and will overcome slightly deficient ductwork systems. If the ductwork system is undersized/deficient, it will be louder as it attempts to maintain proper CFM (versus the PSC blowers where if the ductwork was poor it wouldn't vary its speed to maintain airflow). If it's quiet now, I don't think it will be a problem--I'm just pointing this out about variable-speed blowers. Once you get a few quotes, post back with the info and we can advise.

Karen You are asking too much as those on the forum can not survey your site. There is a standard procedure in flushing lines. It is done everyday. There is no reason for you to know the details. It is an accepted practice in the industry. For lines that are concealed behind walls/ceilings etc and must be replaced, they are run outside the home and concealed by a plastic cover running from the condenser up to the attic and connected to air handler or furnace/evap coil. Again not very esthetically appealing to the eye but done everyday. It is important though that existing lineset is the correct size to the new AC condenser setup. IMO
