Our AC stopped working a year after installation. We spoke to the company that installed it and had another company come out to look at it. Both said there was nothing wrong with it and we were told to use thinner filters. After several years of being miserable over the summer months and thinking we were crazy, we decided to try one time with a company we hadn’t used before. We called FlowRight and they were able to come out and see us on short notice and more importantly, they were able to accurately identify the problem and fix it. Joe was amazing. Very knowledgeable and willing to tell and show you what he was doing. They came out after hours and had our AC up and running within the hour. They were very reasonably priced as well. My biggest regret is not calling them sooner.
