I am new to the forum so thanks for any pro's advice in advance.
I just bought an old house at the beach. In 2004 the previous owner installed a Bryant electric heat unit in the attic and a Bryant AC unit in the yard. The owners did not spend a penny more than they had to on the place and it shows in the quality of everything in the house. The efficiency of the system has been on my mind since the purchase.
I do not plan on doing anything myself as I am not an HVAC guy nor plan to be. The pros are the pros. BUT I do want to be a bit knowledgeable about the process.
There are a few things I want to do:
1. Move the current round diffusers from the center of the room to another offset location so I can install ceiling fans.
2. Look into replacing the diffusers with closable registers so I am not heating/cooling unused rooms.
3. Expand the house into a 8x20 sunroom that does not currently have any registers/ducts.
Here are my questions:
1. Are there closable registers available that will attach to 8" round ducts?
2. Is it allowable to move ceiling diffusers away from the center point of the room to mount a ceiling fan?
3. Do I upgrade to a central air system now knowing that I will be expanding the house by an extra 160 sq ft, or do I just bite the bullet and live with the inefficient system until we decide to expand?
4. A close relative has a brand new Carrier heat pump (only the outdoor unit) that they are considering giving us. This may be the ULTIMATE newbie question, BUT... is there such a thing as too big? AND if it would work, is it an insult to the HVAC guy to install a unit that we were given?
Thanks in advance for any help you can give. Just trying to get a 101 course before talking with my local company.
