What is Done in an AC Servicing Visit?

During a scheduled AC service visit, an HVAC (Heating, Ventilation, and Air Conditioning) technician performs a comprehensive set of tasks to ensure that your air conditioning system is running efficiently, reliably, and safely. Regular maintenance by a professional technician is crucial for extending the lifespan of your AC unit and maintaining optimal cooling performance. Here are the services performed by an HVAC technician during a scheduled AC service visit (aka Preventive Maintenance):

1. Visual Inspection: The technician starts by visually inspecting the entire AC system, including the indoor and outdoor units, components, and connections. They look for signs of wear, damage, or corrosion.
2. Thermostat Calibration: The thermostat is checked and calibrated to ensure accurate temperature readings and proper communication with the AC system.
3. Electrical Component Inspection: The technician inspects electrical components, such as wiring, relays, capacitors, and contactors, to ensure they are in good condition and making secure connections.
4. Refrigerant Level Check: The technician measures the refrigerant levels in the system to ensure they are within the manufacturer’s recommended range. If levels are low, it might indicate a refrigerant leak.
5. Condenser and Evaporator Coil Cleaning: The coils in the condenser (outdoor unit) and evaporator (indoor unit) are cleaned to remove dirt, debris, and dust that can hinder heat exchange and cooling efficiency.
6. Air Filter Inspection/Replacement: The technician checks the air filter and replaces it if it’s dirty or clogged. A clean filter ensures proper airflow and improves indoor air quality.
7. Condensate Drain Inspection: The condensate drain line is inspected to ensure it’s clear of blockages. A clogged drain line can lead to water leaks and damage.
8. Fan and Motor Inspection: The fan blades and motors in both the indoor and outdoor units are inspected for proper operation, lubrication, and any signs of wear.
9. Safety Control Check: Safety controls and switches, such as high-pressure switches and safety shutoffs, are tested to ensure they are functioning correctly.
10. Duct Inspection: If applicable, the technician might inspect the ductwork for leaks, blockages, or damage that could affect airflow and cooling efficiency.
11. Tightening and Lubrication: Loose components are tightened, and moving parts are lubricated as needed to reduce friction and improve efficiency.
12. System Performance Test: The technician tests the cooling performance of the AC system to ensure it’s achieving the desired temperature. They also assess the airflow to make sure it’s balanced and adequate in all rooms.
13. Energy Efficiency Check: The technician assesses the energy efficiency of the system and provides recommendations for improving efficiency, such as adjusting settings or upgrading components.
14. Overall System Evaluation: Based on their findings, the technician provides you with a summary of the system’s condition, potential issues, and any necessary repairs or adjustments.
15. Maintenance Recommendations: The technician might offer suggestions for ongoing maintenance tasks you can perform between service visits to keep your AC system in good shape.

Regular AC maintenance is important to prevent breakdowns, improve energy efficiency, and extend the lifespan of your system. You should schedule a professional HVAC technician for a comprehensive service visit at least once a year, typically before the cooling season begins.

How much should it cost, assuming there are no issues?

• The cost of an AC service visit can range from $75 to $200 or more, depending on your location and the service package offered by the HVAC company.
• Some HVAC companies offer annual maintenance plans that include multiple service visits throughout the year, typically for a higher upfront cost but potentially at a discounted rate per visit.
• Keep in mind that prices can vary significantly based on regional differences in labor costs, market competition, and the level of service offered.

Investing in regular AC maintenance is a wise decision. It can help prevent major breakdowns, extend the life of your system, and improve energy efficiency. If the technician finds any issues during the service visit, the cost might increase because of the need to do repairs or additional work. Always ask for a detailed breakdown of the services included in the maintenance package and their costs before scheduling the visit to avoid any surprises.
