We found out about Commonwealth Cooling & Heating LLC through recommendations around the neighborhood.
We've had them for routine service and they've been great and on time. Everything has worked out as they said they would, so they're knowledgeable. When we had minor problems with our system, they took care of them quickly. We have a yearly service plan with them and we had a problem with our humidifier once, which they took care of right away. Our recommendations with our friends weighed heavily on our decision. What stood out to me about Commonwealth Cooling & Heating was that they were good to their word and had good pricing!
