Our A/C condensor died this week, and we need a new one before we melt in this New England heat.
We also have a 24 year old Lennox furnace that works well, but we are concerned that it could also die at any moment.
We got 4 estimates to replace the condensor / coil with the option of a furnace replacement. We narrowed it down to two based on reputation and availability.
Lennox ACX13 condensor + CX34 coil, with a G60UHV furnace option (cheap AC with variable speed furnace)
Lennox XC14 condensor + CX34 coil, with a G50UH furnace option (quieter AC with single stage furnace)
Both estimates are for the same tonnage and BTUs, and are comparable after factoring in energy rebates.
Other notes: Our townhome is about 1,200 square feet, with adjoining neighbors on both sides. None of the contractors performed a manual J calc, stating that it is not necessary, and should use the originally designed townhome calcs. We plan to move in 3 years, so long term savings is not a huge concern. We are more concerned with smooth, trouble free operation, better cooling, and resale value. We also like the idea of a quieter AC, and more efficient furnace operation.
* Contractor 2 mentioned that we would qualify for a $500 rebate if we go with the XC14 for having seer/eer greater than 14/12. Could we get these ratings with this setup?
* Is the XC14 worth it for the quiet factor, better operation, and resale value?, or would we be just as happy with the ACX13.
* Is the variable speed furnance option of the G60UHV worth the extra cost over the G50UH. We did read some reliability issues on the G50UH on a consumer web site -- should we be concerned?
* Is it worth it to have them both quote an XC14 + G60UHV (better AC and variable speed furnance), or are we over engineering for our needs?
Thanks for any help!
