I'm trying to replace my 20+ year-old heat-pump / Central AC system before it dies (original to my new condo). I've had several contractors come it to quote, but most of them are recommending different brands. I've started my own comparison sheet, but I don't know the brands well and was wondering if I could get some recommendations or if there is a web-site that compares brands.
I'm looking for warrantee/reliability/quality, quiet, efficient (but the town has private electrical, so this is not the primary consideration), and good value for when I got to sell the condo (maybe in 5 years or so)
I have a 2.5 ton system. I am also having an air filter installed, but these all seem similar w/ a 5" or more media filter. My understanding is that the electrical ones are not significantly better.
Rheem 13 SEER vs. Trane 14 SEER
Bryant 15 SEER
Lennox 14 SEER
Carrier Comfort series
Thank you for any and all recommendations in advance.
Those are all quality brands but the most important part is the contractor.
Get the exact numbers of the products in question and get the ratings for them to compare. SEER, EER, cooling capacity, HSPF and heating capacity.
I just did a comparo of some of our brands. It varied widely on efficiency, espeically heating. And heating capacity. One brand was very lacking along those lines. That can mean more $$ in heating costs.
Key is best possible install and proper sizing, hard to find sometimes.
Here's some 2.5 ton R410a options
American Standard HP, Indoor blower SEER/HSPF Capacity Cooling/Heating
4A6H3030, 4TEE3F31 14.00/8.00 31,000/28,600
4A6H4030, 4TEE3F31 14.00/8.25 29,600/27,000
RPNL-030, RHLL-3617 15.00/9.25 29,800/31,600
RPPL-030, RHLL-3617 14.50/10.10 29,000,26,600 (heating output a week but incredible HSPF)
FT4BD-030, C5BA-30/VS blower 14.00/8.50 29,600/29,600
FT4BD-030, CE36D44/VS blower 15.00/8.40 30,000/29,800

Scan the forum for how often homeowners are left hanging by bad installers. If you do, you'll care less about which brand to buy and care more about which installer to choose. Start asking the right questions and you’ll find out that few if any of the companies you’ve talked with are going to do things correctly from start to finish.

On a new Heat pump system, I would want a var spd air handler with the following minimum metrics:14-15 SEER, 12 EER, 9 HSPF. You want to verify the BTUs in both cooling and heating on the system you are considering. Some system configurations/brands/models will shortchange you on the size you require.
Despite what the amateur regular members say, the pros all advocate separating the better companies from the wannabes by asking the simple question, "How do you determine the size of the system to replace my existing system?" Any answer except the one referring the ACCA Manual 'J' method (such as guessing, using the old equipment size, square footage of the space, etc.) are grounds to not even consider the offending company. The ONE you find that does do the load analysis by calculation is the company you should likely go with. They'll also ask about comfort, even temeratures in each room, look at the duct system (if it's visible) and finally will present you with two or three options on equipment. Multi-stage, variable speed products are far superior for comfort. But brand is pretty much the bottom of the list on what to install. I'd ask the installing company if what they're proposing is a builders model. I doubt it will be but you should know that all manufacturers have a builders model. All manufacturers produce equipment under multiple brand names. So choose your installing company far more carefully than you would the brand, then go with their recommendation. After all, if they take the care to properly size the equipment, don't you think they're going to want to install equipment that will meet your expectations and not have unnecessary breakdowns?
If YOU want change, YOU have to first change.
If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!
True enough. However, I want mysti to ask way more questions than that.
