Bob is such a professional, knowledgeable artisan in his field of HVAC. We have known him for over 25 years, and his response is so quick. Yesterday, with the sweltering heat, we made a call, and the problem was corrected within 45 minutes after his arrival. Ahhhh, what a nice, comfortable home to sleep in last night. We recommend Bob Bartlett for all your A/C needs. Thank you, Bob!
