Heating and Air | Experienced HVAC Repair in Omaha, NE

Yes, that humming sound often indicates a failing compressor, which is unfortunately a frequent problem for Omaha AC units during our intense summer heat waves. The compressor is the heart of your cooling system, and constant cycling in high temperatures can cause it to overheat and fail. We recommend turning the system off immediately to prevent further damage and calling for a professional diagnosis. Our technicians can assess whether a repair or replacement is the most cost-effective solution for your specific system.

A frozen evaporator coil is a common issue in Omaha homes, often caused by restricted airflow from a dirty air filter, low refrigerant levels, or a failing blower fan. When the coil freezes, it blocks airflow and can lead to water damage when it thaws. First, turn your AC to the 'fan only' setting to help thaw the coil safely—never try to chip the ice off. The most important step is to call a professional. We'll identify the root cause, whether it's a simple filter change or a refrigerant leak repair, to prevent it from happening again.

Preventative maintenance is key to avoiding the compressor failures and freeze-ups we often see. For Omaha homeowners, we recommend a professional tune-up twice a year—in spring for your AC and fall for your furnace. This includes checking refrigerant levels, cleaning coils, inspecting electrical components, and ensuring proper airflow. The most critical thing you can do yourself is change your air filter every 1-3 months, especially during peak seasons. This simple step maintains airflow and efficiency, protecting the heart of your system from the strain of our climate.
