    Mismatched system?

    We just bought a different home with a Bryant system. The Heat pump is a model 265ANH048000 4 ton (15 SEER) and the coil is a CNPVP4824ACA. We had the system serviced and the Technician told us that the coil that is installed isn't rated for a 15 SEER Bryant Preffered Series Heat Pump. He said the coil is for a 13 SEER unit. I looked up the coil on the web and it's an "N" coil?? There is little space for the coil so maybe that's why an "N" type was used? Anyway, he suggested we get this fixed so we can enjoy the higher SEER rating of the Heat Pump. The system seems very nice and quiet. The house feels really comfortable all the time but we do want to be energy efficient. Comments on the system match?

    Really great news!!!

    Thanks Isuredo. We were hoping this was an OK match. The company that installed it originally is out-of-business which is sad. The install looks very good to me. Very neat and nice routing of the lines. Thanks again!

    More inquiry.

    Isuredo - does the ARI match show what my expected SEER andor HSPF could be? Of course we are hoping this system will be efficient. The Furnace is a 92.3% single stage 75K BTU unit, says Comfortaire on it. Furnace is downflow and short, measures only 39" high IIRC. Furnace looks older than the HP. Previous owner says the furnace was installed in 2003.

    I don;t think you can mixmatch brands and get a complete SEER match. But as stated, teh coil and outdoor unit are a match, so if you are supplying it the correct airflow, it will be equivalent to a 15SEER systme fomr the refrigeration side.

    However, the Comfortaire unit, probably has a lower efficiency PSC blower motor in it. Hopefully it's a 4 ton blwoer and is set ot high and your dictwork doens't have high static pressure.

    Most likely, it's probably about 14 SEER overall as is.

    Furnace stats.

    Yes, Motoguy128, the furnace does have the 4 ton blower. I see from Heat Controller's (Comfortaire) site, the furnace was offered standard as a 3 ton blower and 4 ton was an option. Thank goodness we do have the 4 ton option. I crawled into the attic and think I found the bad. There is a 16" flex duct from the cold air return to the furnace. I only found one cold air return! I'm not an HVAC Engineer (just a homeowner) but the return ducting seems poor for a 2900 square foot home. The air filter is an Aprilaire 2400 and the filter element looks new. We may need an HVAC specialist to get us some more return air. Not sure how since the 16" flex is stuffed through a closet upstairs? Opinions?
