FAQ
Frequently Asked Questions
Answers to the questions homeowners ask most about AC repair, installation, maintenance, and choosing a new air conditioner.
Your air conditioner should be maintained once a year, ideally in spring before the cooling season begins. Annual service keeps the system running efficiently and gives technicians a chance to catch small issues before they turn into mid-summer breakdowns.
The best time to book AC maintenance is early spring, before your system is working every day. Booking early avoids the seasonal rush and gives you time to address any issues before the first heat wave.
Most AC maintenance visits take about 30 to 60 minutes, depending on the system’s age, condition, and accessibility. During the visit, the technician inspects, cleans, tests, and checks key components to confirm the air conditioner is operating properly.
Yes. An air conditioner can appear to be working while still developing issues with coils, refrigerant, airflow, or electrical components. Regular maintenance extends equipment life and identifies problems early, before they affect comfort, efficiency, or reliability.
Most filters should be checked monthly and replaced every one to three months, depending on the filter type, pets, dust, allergies, and system usage. A clean filter protects airflow, efficiency, and the overall health of the system.
If we find an issue, we explain what we found, why it matters, and what your options are. Some items may be minor adjustments, while others may require repair or replacement. Our goal is a clear, informed decision.
