Frequently Asked Questions
How long does a typical AC repair take?
A typical AC repair can vary in duration based on the issue. A simple fix, such as a clogged drain line or a minor electrical repair, can often be completed in as little as one to two hours. More complex problems, like a refrigerant leak or a compressor replacement, can take several hours or even require a second visit. Our technicians work efficiently to diagnose and fix the problem, minimizing your downtime. We will provide a clear timeline after our initial inspection so you know what to expect.
When should I consider replacing my AC instead of repairing it?
The decision to repair or replace often depends on the unit's age and the cost of the repair. If your AC is over 10-15 years old and a major component fails, it's usually more economical to replace it with a newer, more efficient model. Frequent repair needs and a significant drop in efficiency are also strong indicators that it might be time for a new system. A costly repair that amounts to more than 50% of the cost of a new unit is another clear sign to consider replacement. A professional technician can help you evaluate the best option for your specific situation.
How can I maintain my AC unit after repair?
After a repair, the best way to maintain your AC unit is to schedule regular professional maintenance. A professional tune-up ensures the system is running at peak efficiency and can catch small issues before they become major problems. Between service visits, make sure to regularly clean or replace the air filter, as a clean filter is crucial for good airflow. You should also keep the outdoor unit clear of any vegetation and debris. These simple steps will help ensure your AC continues to work reliably and efficiently for years to come.
How often should I get an AC tune-up?
You should have your AC professionally tuned up at least once a year. The ideal time for this is in the early spring, before the heavy cooling season begins. A tune-up ensures your system is in optimal condition to handle the summer heat and helps prevent unexpected breakdowns. Regular maintenance can significantly improve your AC's efficiency, lower your energy bills, and extend the lifespan of your unit. It is a proactive step that provides peace of mind throughout the cooling season. We also offer comprehensive maintenance plans to ensure that your air conditioning unit is in top shape year-round.
