Advice for a new heat pump system

I am a townhouse owner located in the Boston area. My HVAC system is a mismatched 2-ton Bryant heat pump with Fedders air handler. The air handler will not last the winter.

I bought HVAC-CALC to confirm my heat load, and then I asked my HVAC pro (a Bryant dealer) to propose a new heat pump with variable speed air handler, providing 13 SEER and 8+ HSPF. In this climate HSPF is more critical than SEER, but you must buy higher SEER in order to get higher HSPF.

The contractor reported back that only 10 SEER Bryant heat pumps are available now (no 13 SEER units in-stock before April 2006). VS air handlers are currently in stock. He offered the following choices:

1. First, install a new Bryant FV4BNF002 VS air handler now to match the current Bryant R-22 condenser. Then, in March/April swap out the R-22 condenser with a 13 SEER R-410a unit thus yielding 8 SEER.

2. Simply install a new 10-SEER R-22 condenser with VS air handler now, yielding an HSPF of about 6.9.

My only knowledge of HVAC comes from reading this forum, but I’m concerned that the first option might lead to R22-R410 cross-contamination. Should I be concerned? The 2nd option would solve the air handler problem but would lock in a lower efficiency system. Our electricity rates are high and rising 27% in January. Fossil fuels are not an alternative. Which alternative should I choose? Any insights would be appreciated.

Thanks for your help.

Call another contractor.

Sounds fishy.

Go with another brand of unit that is available in higher seer. Goodman/Amanna units new units are very nice equipment (contrary to what you hear on here) and quite affordable as an added bonus. Make sure you have a good contractor to do the install.

I respected your name so much, Mr Rowan Atkinson. Why the hell would you recommend a Goodman?
Only do that if you know the customer has stage 4 cancer and will not be around long!
I'd put one of those things in that you can't stop. Kind of like a train, only different.

fv air handler are for puron. r-22 uses fk air handler.
i think he does not install puron systems and thats why bryant does not have a 13. all of carrier and bryant 13 seer systems are puron not r-22. r-22 will be introduced into carriers new line of 13 seer equipment.
r-22 is being replaced by r410a ( puron) get another contractor and stay with the bryant, vary good equipment. now i will recommend the reliant models which are bryant deuxe units.
another thing is a variable speed air handler will make 13 seer with a 12 seer condenser and 14 seer with a 13 seer condenser.

i also donot recommend amana goodman which is still a janitrol.

I've always preferred a scroll compressor for better cold weather heating. There's a scientific explanation for it but don't recall off hand what it is. I also prefer demand defrost to eliminate hundreds of unnecessary defrosts each winter though I may be in the minority on that one.

I'm with you on this one Baldloonie, my heat pump is a timed defrost, and I wish it was a demand defrost. I'm really supprised that with these days of energy conservation that demand defrost on heat pumps in not manditory.

Carriers heat-pumps tend to do very well in cold climates. they are designed to do.

13 seer will be a nation-wide min. starting in January, You better call another contractor. Also, you should go with a Puron system, 410a, and a Variable Speed air ahandler.

If you are in as cold of a climate as you seem to be in, you may want to consider a duel-fuel system. Duel Fuel means that you have a heat pump and a gas furnance. The Furance is used in place of heat strips which is used during peak demand (colder periods).
