“The technician Brandon Summers was very punctual. His technical knowledge and “honesty” is second to none. To be honest I have came across a dishonest technician. Mr. Assessed the problem within 5 minutes and we went from needing an A/C replacement setting the system to recognize the main thermostat. One Hour needs more professional and trustworthy technicians like you. Keep up the good work. Theron & Julien”
