dizzy

the pricing for a two ton HP system is absolutely absurd.

I would never purchase HVAC from a big box party including Costco. THe pricing suggests you are being taken advantage of.

what is your location?

these are my minimum specs for a new HP system. both outside and inside units should be replaced to have a properly matched system.

15 SEER, 12.5+ EER, 9 HSPF
best matching VS air handler
full BTUs in both cooling and heating for your rated size
R-410a refrigerant(same as Puron)
scroll compressor preferred
electronic demand defrost preferred
thermostat with "dehumidify on demand" feature
staged backup heat strips
new and correctly sized refrigerant lineset

you want a thorough inspection of your ductwork system. size, overall condition, supply and return lines, insulation qualities, leak test, etc.

any hot/cold spot issues in your home should be addressed.

I would only use authorized dealers for the various brands that provide quotes. see mfg websites.

I would look at Trane/AmStd,Rheem/Rudd,Carrier/Bryant.

I would not purchase a new HP system that did not have electronic demand defrost.

IMO

Thx for the reply tigerdunes,
I have quotes from 4 different installers, Costco actually offers the best bang for the buck. They contract well known HVAC companies in the area to do the work. I understand savings are $1k+ using your Costco membership.

Are you saying the above system isn't matched? The Lennox XP17-024 has a SEER rating of up to 17.70 and 9.50 HSPF. It is a scroll compressor...

I have a higher quote from a different (well established) installer who was listed on Trane's website (comfort specialists).

I'm in the Seattle area.
