Unless your furnace has a high eff or var speed blower, you are wasting your money on a 15 SEER condenser. I assume a matching Carrier evap coil and new refrigerant lineset. You don't want a third party brand. Why not a matching Day and Nite condenser to have a complete matching system? For California, I don't think the price is too bad for a 5 ton.

Hi tigerdunes,

I guess we asked for carrier because we recognized the carrier name and not Day & Night. Also assumed my former general contractor installed the cheapest furnace he could find.

So you're saying stick with a 13 SER Day & Night 5-ton condensor if the existing Day & Night furnace is not high-efficiency or variable speed.

Everything is new. It's a major remodel that replaced the furnace/blower/condenser. I'm assuming the furnance and evap coil are both by Day & Night. The contractor said the unit was hanging from the rafters in the attic space.

Thanks!

Perhaps I misunderstood. If you already have an evap coil mounted, then get the brand and model and match it up to the correct condenser. That's the best and only way to go. What size is home and furnace?

I just climbed up there to take a look. I could only see a label on the furnace that said "Day & Night" and a manual that said "International Comfort Products" Model N8MSL/N8MSN. I could see the insulated freon line running into another sheet metal box at the other end of the furnace, but I couldn't find any writing or labels on it. So I can't tell what type of cooling coils it has or whether the blower is variable speed or high-efficiency.

First you need to know and understand exactly what you have including evap coil and furnace.

I would call a day and night dealer first.

What size home? Why do you think you need a 5 ton? New furnace has a 5 ton rated blower. Any filter cabinet? Get these questions answered before you make a mistake.

IMO

That model of Day & Night furnace is not a high efficiency unit so there is no need to try and go with a 15 seer condensener. Also, it is never recommended to mismatching a system especially a lower end brand with a higher end brand because you will just end up with more problems which will cost more in the long run. I would either install a Day & Night 5 ton 13 seer condenser which should cost you $2,900 or replace the whole system for around $4,800.

OP is certain he already has an evap coil installed?
