HVAC bid - apples, oranges, and bananas!
Our 19-year-old HVAC system just died, and we'd really like to have a new one on line again before the weather gets hot, which might be soon in Maryland! Here's the problem: I don't speak HVAC. I'm hoping for some help translating, specifically regarding the quality and price of the systems I'm considering purchasing.
We have a 2-zone system for our 3-story house. The upstairs unit (a heat pump) was replaced two years ago, and is fine. The downstairs setup requires a gas furnace and AC, and heats/cools the main floor, about 1670 square feet with 9-foot ceilings. All three companies bidding this job are offering various flavors of Carrier systems. The sheet below shows a bid by one company, three different options, and I would love any advice you can give me about these options and pricing.
Thanks so much for any info you can give me!
