Reliable Repairs for Common and Complex AC Issues

A malfunctioning air conditioner can quickly disrupt your comfort, especially during the peak of Corona’s summer heat. Whether your system has stopped blowing cold air or shows inefficiency, we can provide practical, long-lasting solutions. 

Our technicians don’t just show up to diagnose the problem. We offer honest, informed guidance to help you make a confident decision for your home. With fully stocked trucks and deep technical knowledge, most repairs can be handled during the initial visit, saving you time and unnecessary stress.

The following are some of the most common air conditioning issues we address:

• AC leaks – Refrigerant leaks reduce system efficiency and can lead to costly damage or environmental harm. We locate and seal leaks quickly, then recharge the system to restore performance.
• Blower motor problems – If your AC is running without air coming through the vents, or you hear strange noises, it may be a failing blower motor. We can assess the issue and repair or replace the motor as needed.
• Electrical failures – Faulty wiring, bad relays, or tripped breakers can cause your system to stop working. Our team can handle electrical repairs safely and thoroughly.
• Dirty or clogged filters – Restricted airflow from dirty filters can strain your system and reduce indoor air quality. We can clean or replace your filters to keep air moving freely.
• Frozen coils – This can indicate airflow restrictions or low refrigerant. We can uncover the cause and resolve the issue to prevent further complications.
• Bad capacitors – A failed capacitor can prevent your AC from turning on or staying on. We stock various capacitors and can replace them on-site.
• Sensor issues – Faulty sensors can lead to inaccurate temperature readings or cause your system to cycle improperly. We can test and replace them to restore proper function.

Each service call begins with a complete diagnostic evaluation and safety check to pinpoint the root cause. Once we've identified the problem, we walk you through your options and give you transparent, upfront pricing before beginning work. After completing the repair, we will follow up to confirm everything is running smoothly because earning your trust doesn't end when we finish the job.
