"Our AC went out and we needed to get it fixed ASAP for a family reunion we were having at our house in the coming days. I submitted an Angi request and Tony was the first to call within minutes. He was very friendly and professional, and was able to schedule a same day appointment amidst the heat wave and countless others experiencing AC issues. Once he arrived he conducted a thorough diagnostic and determined what the problems were and proposed the fix. The costs were more than reasonable and he was able to complete the repairs in a timely manner and rescue us from the heat and another sleepless night! I would highly recommend Bertolini HVAC Services and they will be my go to for any future HVAC issues."
