    New AC needed

    Hey guys,

    Anyone had a new AC/Heater installed recently? And good brands/rebates anyone knows of? We just added a 500 sq foot addition to our house and our current unit cannot keep up. By 6pm it is 80 in our house. It does not cool off till after midnight and the AC is running 24x7. We might try to squeek through this year, and get one in the winter since we have already maxed our tax credit for installing energy efficient windows. But if there is a good rebate from somewhere else, we may act soon.

    What size is your old unit? I'm in the market for one as ours is 27 years old and the pan on the evaporator coil just rusted through.

    Re: New AC needed

    No matter which brand you get, I highly recommend that you get one of the models with a 2-speed/variable speed fan and a 2-stage compressor in the condensing unit.

    I had a Carrier R-410A system installed 3 years ago. I have a 2-speed fan in the furnace/blower unit, but they weren't making the 2-stage condensing units back then. It doesn't get horribly cold here, but in the winter during heating season, the fan rarely runs at the higher speed, and it is nice and quiet on the low speed.

    Summer is a different story. Because my condening unit does not have a 2-stage compressor, the blower fan is required to run at full blast, and there is significant noise at most of the ducts. The system is able to cool the house quickly, but does a terrible job of dehumidifying. I've had to buy a couple of portable dehumidifers. Also, back then, the R-410A units were designed to run at a higher evaporator coil temperature in order to get the EER up, which further reduces the the dehumidifying capability of the system.

    The newer systems with the variable speed fan and 2-stage compressor have a dehumidfying mode, where the fan runs at a slow speed and the compressor runs at about 1/2 capacity. The longer run time and slow air speed allow for proper dehumidification. I have some friends who have these systems and they really work good. They will cost more, but I think they are worth it. Since the control system can modulate the fan speed and compressor capacity, it can optimize the run time to increase the efficiency and reduce power consumption.

    This fall, when the HVAC guys are looking for work, I'm going to see if I can trade my condensing unit for a 2-stage model.

    There is also a tax credit you can qualify for if the new AC is rated 15 SEER or higher

    Re: New AC needed

    U might want to look into getting a heat pump and electric furnace its what we did back in December. We had a York system put in the 2 stage system with variable speed blower. Our energy bill went poof to next to nothing and its so much more comfortable inside. Another added bonus with the York was u get the college team panels on the outside of the heat pump so Cy is proudly displayed.

    Not sure, our house used to be 1500 sq feet and it was enough to cool that all off. I will get you some details.

    Yeah the one I was looking at was SEER 16, they also make a 19 model, but I bet that one is pretty pricey. I have maxed out my federal tax credit for energy efficiency in 2007 by putting in new windows. So I may have to wait till 2008 for this.

    So do heat pumps work as good as as traditional ones? What are the pros/cons? I know nothing about them.
