I've gotten four quotes on installing a/c, quotes fall within $600 from
lowest to highest and all the estimators came up with recommending the
same size unit @ 1.5 ton with the newer coolant.

I have narrowed my choice to two companies, based on recommendations
from this group and my initial meeting with the company rep. Both
recommend a Carrier Comfort, with one offering Lennox Elite and the
other offering Lennox Merit as alternate choices.

Any comments on the above machines? With relatively comparable prices,
which would you put in your home?

I'd also appreciate general information on how often anyone has had to
have their units serviced and an average cost per service call. One
company is offering 10 year parts and labor on either unit, while the
other company offers 10 years on the Carrier and 5 on the Lennox.

Thanks for your helpful comments.
