What Is an AC Tune-Up and Is It Necessary?

Every scorching summer, when temperatures rise, there is nothing more delightful than seeking relief indoors with cool and comfortable air conditioning. A central air conditioning system, comprising indoor and outdoor units along with various internal components, is more than just an external box near your home. Similar to a car, it can operate efficiently and reliably with regular maintenance. That's why AC tune-ups, also known as air conditioner repair, are crucial for maintaining your home.

Air Conditioning (AC) Tune-Up

While air conditioners are designed and tested to run reliably for years, an annual AC tune-up is essential for ensuring peak performance and prolonging the lifespan of your HVAC system. Neglecting routine maintenance can lead to higher utility bills, reduced comfort, and increased strain on system components, which may result in a shorter lifespan or even complete failure.


During regular cooling system operation, critical components like the evaporator coil or condenser coil can accumulate dust, dirt, moisture, and microbial growth. If left unaddressed, these issues can decrease efficiency, damage component materials, and shorten the system's lifespan. In addition to scheduling regular AC tune-ups, it is advisable to have an annual tune-up for heating components or opt for a comprehensive preventative maintenance service for your entire HVAC system. Proper maintenance of both heating and cooling units can significantly extend the lifespan of the entire system.

While homeowners can handle simple tasks like replacing air filters, it is recommended to call a qualified HVAC technician for regular air conditioning system tune-ups. This ensures reliability, longevity, and the prevention of potential issues down the line. HVAC professionals will check cooling temperatures and identify signs of possible problems that could lead to trouble in the future. Scheduling an AC Tune-Up or annual HVAC system preventive maintenance service is relatively affordable compared to the costs of more severe issues that require extensive air conditioner repairs. In the long run, this proactive approach can save you money. The costs of AC tune-ups are relatively low considering the benefits they provide. Not only does annual maintenance optimize the energy efficiency of your system, but it also helps prevent larger and costlier issues in the future.


To ensure the smooth operation of your AC unit and all its moving parts, we recommend scheduling at least one annual tune-up. Ideally, this service should be performed in the spring before the cooling season intensifies. If you live in a warmer climate or extensively use your system, consider scheduling a second maintenance visit during the peak season to maintain optimal performance throughout the year. If it has been longer than usual since your last tune-up, you may notice signs indicating the need to contact Stable Temp HVAC:

  • Higher-than-expected energy bills

  • Reduced airflow from cooling vents

  • Higher indoor temperatures or inadequate cooling

  • Constantly running AC or frequent cycling on and off

  • Increased indoor humidity If you experience any of the above issues, it's time to call a professional HVAC technician.


When you contact your local HVAC contractor to schedule an air conditioner tune-up, expect the check to take about an hour, depending on the dealer and their service routine's thoroughness. If the service technician identifies any issues that require attention, the duration may be longer, particularly if they need to order replacement parts.

During a routine maintenance service call, the dealer will assess the air conditioner's performance in different modes of operation, determining its condition and whether repairs or adjustments are necessary. They will then disconnect electrical power to perform various inspection tasks. While specific maintenance services may vary among contractors, most HVAC dealers conduct similar tasks during a standard check-up appointment.


The cost of an air conditioner tune-up varies significantly among HVAC dealers. Some companies offer more comprehensive services with performance guarantees, while others may provide a basic service at a discounted rate to attract new customers. Both approaches can effectively prepare your air conditioner for optimal operation during the hot summer months, as long as the service is performed by a reputable HVAC contractor.

If summer is approaching and your AC hasn't been serviced recently, Stable Temp HVAC is here to assist you!
