It's recommended to schedule professional AC maintenance at least once a year, ideally in the spring before peak usage. Regular maintenance helps ensure your system is operating efficiently, can prevent costly repairs, and may extend the unit’s lifespan. During a service visit, technicians typically inspect components, clean coils, check refrigerant levels, test controls, and replace filters if needed.

A standard AC service typically includes a thorough inspection of the system, cleaning of coils and drains, lubrication of moving parts, checking refrigerant levels and pressure, testing the thermostat, and examining electrical components. These steps ensure the air conditioner is operating safely and efficiently, minimizing the risk of mid-season breakdowns.

Warm air from your AC could be caused by several issues including low refrigerant, a dirty air filter, electrical problems, or a malfunctioning compressor. It may also result from a thermostat setting error or blocked ducts. A professional technician can diagnose the root cause and restore proper cooling performance quickly and safely.

To improve AC efficiency, start by cleaning or replacing filters regularly, sealing air leaks in your home, using a programmable thermostat, and keeping vents unblocked. Annual professional maintenance and keeping the outdoor unit free from debris can also significantly boost system performance and lower energy bills.

Most central air conditioning units last between 10 to 15 years. With regular maintenance and prompt repairs, some systems may function well beyond that range. If your unit is nearing this age and experiencing frequent issues or high energy usage, it may be time to consider a replacement for improved reliability and efficiency.

If your AC unit is more than 10 years old, requires frequent repairs, or struggles to maintain comfort, replacement may be more cost-effective in the long run. However, newer systems with minor issues can usually be repaired. A qualified technician can help assess your unit's condition and recommend the most economical option.

Common signs include warm air blowing from vents, weak airflow, unusual noises, strange odors, leaking water, or increased energy bills. If you notice these issues, it's important to have your system inspected to avoid more serious damage and ensure your comfort throughout the season.

Refrigerant is essential for cooling. If your system is low on refrigerant due to a leak or improper charge, it will struggle to cool your home, may freeze over, and could suffer compressor damage. Only licensed HVAC professionals should check and refill refrigerant as part of routine service or repair.

Yes, dirty air filters can restrict airflow, causing your AC to work harder and less efficiently. This can lead to higher energy bills, reduced cooling performance, and even system breakdowns. Filters should be checked monthly and replaced as needed—typically every 1 to 3 months, depending on usage and environment.

Yes, annual AC servicing is highly recommended. It ensures all components are functioning correctly, helps catch small issues before they become major repairs, and keeps your system running at peak efficiency. Many manufacturers also require annual maintenance to keep warranties valid, making regular servicing a smart investment.
