The problem you describe does not match the normal situation regarding warm and cold environments, unless we are talking about really cold. We need to know a bit more about the environmental conditions. Is the piano in a house ? What is the minumum temperature it is exposed to, and what is the maximum. If these are within normal house temperatures, I would think you need to get a new technician as your problems are not then properly solved by simply warming up the piano. Action problems you describe usually are related to humidity problems. In times of high relative humidity you should experience these problems (If you experience them at all) and in times of low relative humidity these usually lessen or disapear. Give us more information and we will be able to help you better.
