Highly recommend!Catherine L.Catherine L. ★★★★★ On a Saturday morning, I couldn’t find my cat and was hearing claws on the metal of the air vents. I tried to coax him out to no avail. So I called for help and was able to speak to someone right away. We had a technician on the way in less than 10 minutes! I’m very impressed and grateful for the quick response time. Apparently my cat had found a great new hiding place as he came sauntering out while the technician was on the way. So I didn’t need their help after all but I’m nonetheless thankful and we’ll definitely be using them in the future.Maggie C.Maggie C. ★★★★★ Tom is fantastic!
