"Our natural gas furnace stopped working the day after Christmas. Most heating services were closed for the holidays but Ocean State was one of the few who would take the Friday afternoon call. Repair were done quickly and heat was back before it was cocktail hour. Ocean State is now our primary HVAC service provider."

He repaired the system correctly and perfectly, not rushing into a quick or convenient fix. Our home is comfortable again. His professionalism and dedication are outstanding. Highly recommend!"

"Alex was great! Courteous, responsive, prompt, friendly, but more importantly, honest. The job couldn’t be done because of the structure of my HVAC system, yet Alex (and Vinny) took the time to explain the problem and tried, albeit unsuccessfully, to seek an alternative solution. I have such respect for his honesty. I highly recommend using this company, for that reason alone."

"When they first came out, they got the AC to stop leaking inside my basement and they clean out some stuff in the system. Then about 3 days later the fan on the condenser kept going on and off. I reached out again and we made an appointment, but no one showed up. Then they showed up unexpectedly 3 days after our scheduled appointment and they fixed the issue."

"Bruce really listened to how I answered his questions and designed a natural-gas fueled steam boiler system that met all the requirements with the expansion potential I requested. During pre-installation logistics and the day of installation, Bruce and his crew were on-time, courteous and professional. Their work demonstrated the benefits of hiring a fully credentialed company, skilled and experienced at their craft. They completed their work in one very long day so that I could avoid a night without heat during a stretch of very cold January days. I trust Williams & Assoc. and would hire them for additional work in my home as needed"
