Will this hurt anything?

[1-hour]

My contractor just completed installing my new system. Trane XV95, XB13, T803, and all new ductwork. Part of the system serves a new addition (780sft). The addition is not yet insulated and drywalled so all the registers and returns are closed/covered. The remainder of the system serves the existing 1040 sft house. Can/should the system be run in this condition? The contractor said it's fine because there's plenty of return air in the existing house.

Should be ok. If its only for a week.

Twilli says it amazing how some systems run at all

[tinknocker service tech]

should be fine

you dont want the runs in the addition opened untill it is painted

the dust will cause a lot more harm then a little less air can

Thanks. Will try to use sparingly, if at all, until remaining ducts can be opened up, hopefully about three weeks. We've never had a/c other than window unit so we should be able to survive a little bit longer.

Don't let them open them while they are sanding the drywall, how ever, if the unit is sized for the whole house, you may have an air flow issue until they're done.

10x8 supply, 14x8 return closed off to addition. 14x8 supply, 20x8 return open to existing house. 2.5 ton outdoor unit, not sure of cfm setting. The blower seems a little louder than I expected but noise is almost undetectable at registers. We will definately wait until drywall is complete before opening them up. I just don't want cause a problem with the blower motor.
