Best Programmable Thermostat in Charlotte NC

I tried calling three times over three days. No-one answered my calls, and no-one called me back.

My home builder works with Romanoff for HVAC needs. Today a diligent HVAC repairman by the name of Robert came to address an issue I had with the AC. Robert was quick to troubleshoot the problem and went even further as to suggest how to solve the root issue (the breakers and labels were switched for the heavy appliances — range and AC unit) even though it wasn't the AC unit itself. It took him all of about 15 minutes. It was incredible to watch him work. Thank you Robert and Romanoff!
