AC Repair FAQs

Common Questions About Our Service

If your AC isn’t cooling properly, several common issues might be the cause. Dirty or clogged air filters can restrict airflow, reducing cooling efficiency. Low refrigerant levels, often due to leaks, prevent the system from cooling effectively. Faulty thermostats or incorrect settings may also lead to insufficient cooling. Additionally, dirty or frozen evaporator coils, clogged condenser units, or electrical problems like tripped breakers can impact performance. Regular maintenance and timely professional service can help keep your AC running smoothly and cool your home efficiently.
You should schedule AC maintenance at least once a year, ideally in the spring before the cooling season starts. Regular maintenance helps your system run efficiently, reduces the risk of unexpected breakdowns, and can extend the lifespan of your unit. If you use your AC year-round or live in an area with heavy usage, consider scheduling maintenance twice a year, in the spring and fall. During a service visit, a technician will clean and inspect key components, check refrigerant levels, test performance, and make sure your system is operating safely and effectively.
Signs you may need AC repair include warm air blowing from vents, weak or inconsistent airflow, unusual noises like grinding or banging, and bad odors coming from the unit. A sudden spike in energy bills or frequent cycling on and off can also signal problems. If your thermostat isn’t responding properly or there are leaks or moisture around the system, it’s time to call a professional. Addressing these issues early can help prevent more serious and costly damage. Regular maintenance can also reduce the need for emergency repairs.
You can handle some basic AC issues yourself, like replacing or cleaning air filters, checking the thermostat settings, or clearing debris around the outdoor unit. However, more complex problems—like refrigerant leaks, electrical faults, or frozen coils—should be left to licensed professionals. Attempting DIY repairs on these components can be unsafe and may void your warranty. If your AC isn’t cooling properly after simple troubleshooting, it’s best to schedule a professional inspection to avoid further damage.
Our standard response time for AC repair requests in the San Mateo area is typically within 20 minutes, with a 100 percent response rate, based on customer feedback. In most cases, our technicians aim to begin service within 1 hour under normal conditions. For standard repair or maintenance calls, service usually takes 45 minutes to 1 hour, while more complex jobs may take 1.5 to 2 hours. In emergency situations, response times may vary slightly depending on technician availability and current demand, but we strive to dispatch help as quickly as possible.
During the repair service, a technician will begin by inspecting your AC system to diagnose the issue. They may check the thermostat, refrigerant levels, electrical components, filters, coils, and overall system performance. Once the problem is identified, the technician will explain the issue and recommend the best solution. If you approve the repair, they’ll proceed with fixing the problem, which may include replacing parts, cleaning components, or adjusting settings. After the repair, the system will be tested to ensure it’s working properly, and the technician will provide maintenance tips if needed.
