How good are weatherking a/cPost created: 2012-08-17 Type of Equipment: Air Conditioner Views: 320
This question was created on the page: https://www.furnacecompare.com/buying_central_ac.html.
I am in the process of replacing my furnace and a/c unit. The contractor said that my ductwork is undersized (the cold air return opening is only 10x10"). The air flow when my old a/c was running was pathetic (I placed fans on the supply vents and aimed them towards the ceiling). I currently have a broken Williamson that is 1.75 ton unit and a 50,000btu furnace. The furnace works fine.
The contractor wants to replace it with a 60,000btu furnace and 2 ton a/c. Does this seem reasonable? He said since I live in a condo were the ductwork can't be resized that the a/c cooling problem will always exist and will never work to my liking.
Would you keep the old furnace and only replace the a/c. Is there anything that can be done to improve the air flow since my ductwork is under sized?
He suggested putting in a less expensive Weatherking 2 ton unit.
any advice would be greatly appreciated.

All mfg brands of equipment,is good, as long as it's installed right. I have put it many lines. And they all work okay. You need to get bigger ductwork.
This is the only way you can get better air flow. Like the old saying, you can never have enought return air. For a 2ton unit you need 20X10 Return Air Duct. on your supply line you need at least a 18x8 duct with 8-6"runs. Since you need to dump 800cfm of air from you unit. This way you will have proper air flow to get rid of the heat from the furnace and to get rid of the cold air in the summer.
