We need to replace a 15 year gas pack that serves the downstairs portion of our home.
2 quotes so far and waiting on a 3rd.
One quote is a for a Goodman 13 SEER 2.5 ton and the other is for a Lennox 13 SEER 2.5 ton (sorry I do not have the model number details handy at present). I believe the 3rd quote will be for a Trane unit. The Goodman offers 10 years on parts and 1 year on labor. The Lennox offers 10 years on parts and labor together. Not sure what the Trane will offer.
I am getting conflicting guidance on the difference between the brands. Some say Goodman is low end (just above builder's grade) and others say it is built in the same factory as Trane and there is no difference.
I am also seeing conflicting information on Lennox. Some say it is high quality and others say it is not.
To make it more confusing, I am reading that far above brand, the quality of the install trumps everything. In other words, a lower end unit could be just fine assuming the install is done correctly.
Would be grateful for some guidance and informed viewpoints on these issues. Thanks.
