Preventative Maintenance That Pays Off in Peace of Mind

When our team visited a home in Norman for a routine AC maintenance check, we found more than just a few minor issues—it was clear the system was on its last leg. These kinds of checks are crucial for AC maintenance in Norman, OK.
During the inspection, we discovered:
- A blower motor leaking oil
- An extremely dirty blower wheel and evaporator coil
- A charred contactor and a capacitor outside of its acceptable range
- Improper refrigerant levels showing no superheat and high subcooling
After clearing the drain lines, cleaning the outdoor unit, and installing a new thermostat, we talked with the homeowner and our Service Replacement Manager about the best next step. Given the system’s age, lack of warranty, and extent of needed repairs, the customer decided to explore a full replacement to keep up with their AC maintenance in Norman.
They also signed up for our Heritage Maintenance Plan to stay ahead of future issues and keep their new system in top shape once installed. Smart decisions like these are what turn temporary issues into long-term comfort.
