???? Location: Rockwall, TX |Residential Single family house
???? System: 10-Year-Old Lennox Outdoor Unit | 1-Year-Old Air Handler
???? Service: Amana 5-Ton R-410A Condenser Installation
???? The Problem:
A Rockwall homeowner called us when their A/C suddenly failed. We diagnosed a burnt-out compressor—the start winding was reading OL (open line), and insulation on the compressor motor winding failed megohm testing. The outdoor condenser, originally installed 10 years ago, was beyond repair.
???? Our Solution:
As a private label Daikin dealer, we had access to install an Amana 5-ton R-410A condenser, restoring full cooling performance while keeping the 1-year-old indoor air handler in place.
⚠️ Industry Insight:
Due to the 2024 refrigerant regulation change, manufacturers have phased out R-410A equipment. All brands are currently facing shortages of compatible outdoor units. That’s why we advise:
➡️ If your system is nearing 10 years old, and have any major failure on critical components (coil, air handler, compressor, heat exchanger…) replacing both indoor and outdoor units together is a smarter, long-term move—saving time, labor, and future headaches.
✅ The Result:
• Fast restoration of cooling
• Factory-matched performance
• Happy, informed homeowner
