HVAC Upstairs QUESTION - DIY Chatroom

Statecowboy · 09-14-2007, 05:04 PM

Our house is an older (1920's) style and the upstairs does not heat or cool adequately, so I thought about having a second unit installed upstairs. I've had a couple of quotes for around 6-7k to install a new unit and one contractor told me he was 100% sure he could replace my ac a-coil (which is pretty old) and compressor and the upstairs would be fine. He's saying that because it's old, it's probably clogged up with dirt etc. and is blocking a lot of the flow from my blower which should go upstairs.

My question is, does this sound like a normal problem, and would 2400 be too much to pay for someone to replace the ac-coil, compressor, and balance the system? Also, would 6-7k be too much to pay for someone to put a new unit in the attic for upstairs use only? My upstairs is roughly 24'-30'.

A competent HVAC contractor is capable of determining the size of equipment to adequately cool your home.

Contractors are in business to make as much money as they can, and this attitude causes many of them to put the consumers' needs second.

If this contractor is competent, ask him to show you the calculated cooling load he arrived at to see if the equipment you now have is adequate
