Had been a customer for at least 25 years, but stopped using them when the name was bought by Cropp Metcalf. Found the Original Dwyer was still in business and was delighted. Called at 1:30pm to report AC not blowing cool air. Arrived at 8AM next morning to replace capacitor and check the entire HVAC system(it is 21 years old!). Gave excellent advice on how to set system during this heat wave. By 8:30AM, we had AC! Repair was very reasonably proced. I will use them again for repair and replacement. So glad to have found the original Dwyer!
