The dryer was steaming things vs. drying them. A rainy day when Pat came, the assumption after an internal inspection was that the venting likely needed cleaning, as did the dryer itself. That's honestly almost always the issue with the symptoms my dryer was having. When the problem wasn't remedied, Pat returned promptly, went on the roof for a more thorough inspection and determined the venting didn't exhaust to the outdoors properly. Pat was able to install a new exhaust in the roof and add several feet of new venting to remedy the problem that same day. Fast, courteous, efficient and fair. I will recommend and reuse his services as called for.
