I have used this firm for years and have always been impressed with their responsiveness and courtesy. Today I had a technician come out for a condensate leak from a ceiling vent. He went into attic, took photos and patiently explained the problem and several solutions were presented. I ultimately decided to wait and see if it resolved itself when humidity receded. He didn't try to sell me on expensive repairs I didn't need, just presented the information I needed to decide for myself. I trust them to be honest and knowledgeable and unhesitatingly recommend them.
