Before you spend thousands replacing your AC system, get a second opinion from a licensed local neighbor.

I’m Aaron, owner of SAG Quality Air. I provide residential HVAC diagnostics, repairs, and maintenance in McKinney, Frisco, Little Elm, and surrounding areas.

For a flat diagnostic fee, I’ll troubleshoot your system, explain what I find, and walk you through your options. If a safe, practical repair is possible, you’ll receive a clear price before any work begins. Honest service without sales pressure.

🚨 This is why condenser coil maintenance matters!

This condenser coil was completely packed with dirt and debris, severely restricting airflow. When a condenser can’t breathe, the system has to work harder, which can lead to:

🔥 Higher head pressure
⚡ Higher energy consumption
🥵 Poor cooling performance
🔧 Compressor and component failures
💰 Expensive repairs

After a thorough cleaning, you can actually see the coil again and the unit can properly reject heat.

A dirty system doesn’t always need a major repair — sometimes it just needs proper maintenance.

⚡ Burned Wiring Found on a 10-Ton Commercial RTU

During service on this Lennox rooftop unit, we found severely overheated high-voltage wiring at the main power connection.

Connections like this can cause equipment failure, nuisance shutdowns, and additional electrical damage if they aren’t caught.

We removed the damaged wiring, repaired the affected conductors and connections, and got the electrical side cleaned up and secured.
