Comparing two HVAC bids - would love your input
Hi - normally I post in the "building a home" forum, but I think it's more appropriate to post this here.
We are building a new house, 3700 sq ft, two story, in Austin TX hot climate. Plus separate guesthouse/casita but it will just have an electric heat/cool unit. I have two HVAC bids for the new construction.
I've pasted them each below. My questions are:
1. they both recommend heat pumps for heating and cooling. I've done some research on them, but no real experience. Is that sufficient for TX summers?
2. it's hard to compare apples to apples with the bids. Is there anything that one is including that the other isn't?
3. is there anything missing that you would expect to see in an HVAC bid?
4. The casita won't have ductwork, but how would the exhaust fan work in the bathroom? One bid mentions the casita, but not sure what they're saying.
Bid A is attached here. I'll attach Bid B as a follow-up.
Thanks in advance!
