Case Study: Upgrading a 24-Year-Old HVAC System in Irvine

In Irvine, a homeowner faced a major HVAC dilemma: their 24-year-old Carrier system, still using R-22 refrigerant, was nearly out of coolant and on the verge of breakdown. The aging system had suffered multiple faults and costly repair estimates. As Today’s Homeowner explains, R-22 was phased out in 2020 and prices have soared (meaning over $1,000 for a full recharge). Rather than continue throwing money at repairs for an antiquated system, our All Set Service team recommended replacing the entire unit with a new high-efficiency setup.

We performed a load calculation and chose a 5-ton system sized for the home. The new AC Pro package included an inverter-driven outdoor condenser and a matching indoor furnace. The inverter (variable-speed) compressor continuously adjusts its speed, minimizing the wasted energy of on/off cycling and maintaining a steady temperature. We also installed a modern gas furnace built to ultra-low NOx standards, ensuring emissions below California’s 14 ng/J limi. These high-efficiency components deliver consistent comfort, lower energy use, and compliance with air-quality regulations.

After installation, the homeowner immediately noticed quieter, more responsive cooling and heating. With R-22 eliminated, the new R-410A system operates far more efficiently. In fact, Today’s Homeowner notes that a modern R-410A system can cut cooling energy use by 20–40% compared to an old unit. The customer was very pleased: their home is now comfortable and reliable, with lower expected energy bills and no more worries about costly R-22 recharges or breakdowns. This upgrade solved their immediate comfort needs and left them with long-term peace of mind.
