The service tech JEFF did a wonderful job, very efficient and thorough. Absolutely prompt, they said the tech would arrive between 8:30 and 9:30 AM and he pulled in the driveway at 8:30 on the dot. Explained everything he did, and left the Area around the system cleaner than it was before. The heat pump is running quieter and the house is cooler already. My wife will be thrilled when she gets home from work, that is priceless! I will be recommending gentry to all my friends, family, coworkers and folks at church.
