I am a homeowner that needs assistance. I have found two contractors I like. Both will be installing packaged units for my downstairs (all electric) and a spilt syytem in my attic for my upstairs.

One will use a Tappan System 13 seer packaged and 16 seer spilt system. The other wants to use Heil 12 seer packaged and a 14 seer split system. The Heil proposal is about 9%less. I will be living here for around 10 more years.

Any idea on which is better? Or are they close and I just compare warranties?

Thanks,
Special Ed

It appears the Tappan is more efficient. That's probably why it's more expensive. In other words, you're not comparing apples to apples.

I am a home owner, like you, and I just placed an order for a new package unit (after pouring over the many posts in this forum, reading the several didactical web pages, and receiving advice from several professional members here <img> http://hvac-talk.com/vbb/images/icons/icon12.gif </img>
Wink). I would say that 9% for a higher efficiency system is really not much, since it might also have other features, like variable speed blowers and two stage furnaces, and all the other stuff that the helpful people in this site will tell you about. So, from the consumer point of view I think that a 9% or 10% difference is really not that much more for a presumably better system.

The Tappan split would be a 2 stage unit with the Copeland Ultra scroll. It should be more bucks than single stage and should have a variable speed air handler too. Make sure it does.

If you are in a cold climate the Heil 14 will have demand defrost, eliminating hundreds of unnecessary defrosts each winter, quite the energy-saver.

time and temp will terminate if it aint needed and it will keep coils defrosted and not wait until the frost is heavy. I suspect demand defrost is overrated.

The way I see it, Doc, if it is 5 above zero and windy, a timer will bring on a defrost and could stay in for the whole 10 minutes as with the wind, the coil could never warm up to 70 degrees. But the demand board knows the coil isn't frosty and won't initiate the defrost to begin with.
