Recent Project
Rheem Central Air & Furnace Replacement in Bethel Park
Our residential install team recently completed a full HVAC system replacement for a homeowner in Bethel Park. The aging equipment had reached the end of its service life, and the homeowner needed a reliable, high-efficiency solution before the heating season. We installed a new Rheem central air conditioner and matching furnace — handling everything from equipment removal and ductwork modifications to refrigerant line set installation and final commissioning. The result is a properly sized, code-compliant system built to handle southwestern Pennsylvania winters and summers for years to come.
What Was Included
- Full removal of existing furnace and central AC equipment
- New Rheem high-efficiency gas furnace installation
- New Rheem central air conditioner and outdoor condenser
- Refrigerant line set installation and pressure testing
- Ductwork modifications and plenum fabrication
- Condensate drain line routing and trap installation
- Thermostat wiring and system commissioning
- Final safety inspection and homeowner walkthrough
If your Bethel Park home's HVAC system is more than 15 years old, showing signs of failure, or struggling to keep up with demand, a planned replacement is almost always more cost-effective than repeated repairs. See how our team handles emergency HVAC situations across Allegheny County →
