Fast Shipping, Great Service
I was in a pinch without A/C in the middle of summer. Supply House had the exact part I needed in stock and shipped quickly. I was back up and running in no time.

No air-conditioning is not a cool idea
I thought the capacitor was the problem with my heat pump. It turned out not to be but now ihave a new one anyway installed. This was the problem last time.
The quality is good and I'm happy. I'm keeping the old one as a spare, the price was very good too, anyway I will go yo you next time I have a problem part for replacing it thank you
