Emergency AC Replacement in Larchmont, NY – Fast, Efficient & Eco-Friendly Cooling Solutions

When your air conditioner fails unexpectedly in the middle of a heatwave, quick action is critical. That’s exactly what we delivered for a homeowner in Larchmont, NY who was dealing with a leaking 10-year-old Lennox system. Our team at Sustainable Heating & Cooling responded with a fast, high-quality emergency AC replacement—restoring comfort the same day with a modern, environmentally responsible solution.

The Problem: A Leaking, Outdated AC System

The customer’s existing Lennox system had developed a serious refrigerant leak. At over a decade old, the unit was running on outdated refrigerants and no longer operating efficiently. With temperatures rising and no time to spare, this was a clear case for emergency air conditioner replacement.

The Solution: Rheem AC System with R-454B Refrigerant

We quickly mobilized our team and replaced the failing system with a high-efficiency Rheem central air conditioning unit. This new system runs on R-454B refrigerant, a next-generation, low global warming potential (GWP) refrigerant that aligns with New York’s push for more sustainable HVAC solutions.

Benefits of the new Rheem system:

Improved energy efficiency

Lower environmental impact

Reliable, quiet performance

Compatibility with modern smart thermostats
