It will still be worth it to install the DC. If the temperature fluctuates wildly the piano will still drift around because of that but it tends to be more of a short term reactive change. The DC will still help stabilize the moisture content issues. Try and have the room brought to the temperature that it is when in use before you tune. See the discussion last month (or earlier this one, not sure) about tuning stability temperature versus humidity.

The church where I was tuning has a Broadman grand purchased in 2008. It doesn't hold a tuning for very long. It sits in a large sanctuary and the temp is not that consistant. The music director ask me about installing some dampp chasers to see if that would help. I told him that the strings still might be stretching but wasn't sure. I told him that dampp chasers work good in a verticle piano because there enclosed. He wanted to know if it would be worth putting them in a grand. I told him that I was on piano tech email and that I could get some intake on this matter from guys that had a Lot of experience on this subject and would get back to him. Any info will be appreciated.
