Highlights
- Emergency A/C repair — Jeff responded to a 4th of July breakdown
- System replacement — whole HVAC system finished sooner than expected in 2025
Sergi Oil Heat & AC is an HVAC business that states it offers 24/7 emergency service. When a central A/C stopped working during a heat wave, Jeff responded to a 4th of July emergency, and the repair included replacing the capacitor and cleaning the outdoor condenser, according to a recent Google review. Another recent job replaced a tank and included a tune-up. A recent review also says Jeff was on time and that follow-up was "fantastic." In a 2025 review, Jeff replaced a whole HVAC system, helped identify the right system to install and completed the job sooner than expected. In a separate 2025 review, Jeff performed maintenance on AC condensers for "a very reasonable price."

I’m so grateful I found Sergi Oil Heat & AC! My central A/C stopped working during the heat wave, and Jeff responded to my 4th of July emergency, getting my system back up and running quickly. There were no surprises, just a fast repair that included replacing the capacitor and cleaning the outdoor condenser. I highly recommend Jeff and Sergi Oil Heat & AC!
