Excellent work by Plymouth Heating & Cooling Company. The technician was friendly, skilled, and professional. He diagnosed the issue quickly and repaired it properly. He explained everything clearly, and the pricing was fair. Plymouth Heating & Cooling Company consistently delivers reliable HVAC service that I confidently recommend to others without hesitation.

After the heat exchanger caused the gas heat to shut off after one minute during a severe cold spell, Griffith Heating & Cooling Company! came out the same day and confirmed the problem. By the end of the next day an entire new HVAC system had been installed. Great service, and this wasn't the first time I got a great response from Griffith Heating & Cooling Company!
