Westinghouse, Rheem or Lennox
I have a Lennox furnace that is 27 years old, and is very inefficient. I live in Dayton, Ohio. Manual J comes out to 99000 on coldest day. All units are over 90,000 btu or over. Which manufacturer makes the most efficient system.
Westinghouse systems is:
Model FG6TL1---CVB with matching 3 ton coil
model FT5DB036K Heatpump
White-Rodgers 90 serise thermstat.
Model RGGD-10EZCMS Furnace with RCFLHM3621 coil
Model RPNL-036JAZ Heatpump
Rheem Termostat 41-24312-04
Model G61MPV-36C-090 Furnace
Model XP140-36 Heatpump
Model CR33-48C Coil W 49L25TXV
Line set L15-41-50
Model T8000 W/ OD sensor Thermostat
Companies look sound and check out with the local BB. Warranties are all close to the same.
Any thought advice would be helpful and appreciated.
The Mod with the matching stat will give you a comfort and quiet the rest only dream of Be sure they use the matching thermostat. The RPNL is a nice heat pump as well.
We've sold some Nordyne products. They seem pretty decent with a super warranty. The FT5BD is an R22 unit, the FT4BD is R410a to compare to the RPNL. When you put a Nordyne system on a variable speed blower you end up at 14.00 SEER which may qualify you for a local rebate. If they use the FT4BD and CE36D44 coil, you end up at 15.00 SEER and get the federal tax credit, $300 less taxes to pay Be sure to request a Vision Pro IAQ for best comfort.
Sorry, not a Lennox fan.
