Trusted HVAC Repair in Norman, OK 73072 - Luman Heating and Air Conditioning

Our maintenance service is designed to prevent common problems and keep your system running efficiently. It includes cleaning and inspecting key components, checking refrigerant levels, testing system controls and safety devices, and ensuring proper airflow. For Norman residents, we pay special attention to air filters and evaporator coils, which are frequent trouble spots here, helping to prevent freeze-ups and maintain indoor air quality.

In Norman's climate, evaporator coils often freeze due to restricted airflow from clogged filters or low refrigerant levels. When we respond to a freeze-up, our first step is to safely thaw the system. We then perform a thorough diagnosis to find the root cause, which is typically cleaning or replacing the air filter, checking for duct obstructions, or sealing a refrigerant leak. Our goal is to fix the underlying issue to prevent it from happening again.

As a technician with over 20 years of experience, I recommend considering replacement if your system is over 10-15 years old, requires frequent and costly repairs, or is no longer energy-efficient, leading to high utility bills. We provide a straightforward assessment, comparing the cost of continued repairs against the benefits and long-term savings of a new, properly sized installation for your Norman home.
