I am in the market for a total replacement of 3 units (5,5,2) for my house.
I currently have entry level 10 SEER Rheem units that are a dozen years old and breaking down non-stop. I am looking to replace both the outside units and associated furnaces. Estimated total bill is in the $$$$ to $$$$ range depending on options and models so it is a big job and I want to do it right. House is two stories, faces E/W, is in a hot city, has ceilings from 12-20 feet, 4,400 sq feet total. Media room has the 2 ton unit for it alone. Roughly 250 sq feet of the 4,400 sq feet total.
I'm in the D/FW area and used a half dozen companies over the years for various service jobs. I never done a full replacement or install.
I'm in the middle of the bid process and it's really confusing. Most of the companies seem qualified, they say and do the right things when I ask them about my current units versus size of house, etc.
How do you know who to trust (both install and price)? How much SEER is really needed (value/efficiency apex)? Brands to focus on/avoid? 1 Stage or 2?
So far the quotes are all over the board. Pretty much my range I noted above. Nobody has recommended the same thing.
Any thoughts or advice?
