When certain things foul up CTI is my go to, and that's exactly what happened a couple of days ago when I realized it was getting chilly in my house. I checked the thermostat and only to discover the temperature dropping and it wouldn't turn on. I called CTI and set up an appointment. Zack arrived about 4 hours later right on time and we had heat about 45 mins later. Oh lovely heat!! Can't thank you enough. Good Job!!!
