What’s Included in an AC Maintenance Visit
Each maintenance visit follows a detailed, system-wide checklist to ensure nothing is overlooked. During service, our technicians thoroughly inspect, test, and fine-tune critical components, including:
Thermostat test. A thermostat that isn’t working correctly can’t operate a system properly, so we’ll clean and test it, then calibrate it if needed.
Controls OK? We make sure the thermostat and AC are communicating correctly.
Heat exchanger check. We’ll carefully study your heater’s heat exchanger to make sure there are no cracks or damage that can waste heat and leak deadly carbon monoxide fumes.
Test refrigerant. The liquid refrigerant that flows between your AC’s indoor and outdoor sections is what makes it work, so we’ll make sure you have enough.
Drain review. We’ll inspect your condensate drain line to ensure it’s free-flowing with no leaks.
Air filters. Using clean filters improves airflow and indoor air quality.
Properly connected. We’ll make sure your electricity is properly connected for safe operation.
Run cycles. We’ll run the AC through its cycles, to verify it’s operating as efficiently as possible.
Lubrication. Proper lubrication helps components last longer.
Examine ductwork. We’ll look for energy-wasting leaks and inadequate insulation.
Clean condensing unit. We’ll keep leaves, dirt, and other debris from interfering with your home’s comfort.
Blower motor check. We’ll clean any dust and debris and make sure it’s working.
Fan bearings. Bearings are critical to keeping fans and blower motors operating safely and quietly.
Check electrical connections. Loose or corroded connections can cause poor performance or system failure — we tighten and secure all wiring.
Inspect insulation on refrigerant lines. Proper insulation prevents energy loss and helps maintain the correct refrigerant temperature as it moves between your indoor and outdoor units.
Preventive maintenance plays an important role in how long your AC system lasts and how well it performs. Building on the service steps outlined above, continued care can help reduce unexpected issues and keep cooling equipment operating as intended.

Frequently Asked Questions
What does AC maintenance include?
AC maintenance includes a full system inspection, testing, and cleaning of key components to ensure your air conditioner is operating safely and efficiently. This typically covers thermostat checks, refrigerant levels, electrical connections, airflow, and overall system performance.
How often should I schedule AC maintenance?
Most manufacturers recommend AC maintenance once per year, ideally before peak summer heat. Regular service helps reduce wear on components and lowers the risk of unexpected breakdowns during hot weather.
Is AC maintenance worth it if my system seems to be working fine?
Yes. Many performance issues develop gradually and aren’t immediately noticeable. Routine maintenance helps catch small problems early, improve efficiency, and extend the life of your system—even if it appears to be running normally.
How long does an AC maintenance visit take?
Most AC maintenance appointments take about one hour, depending on system type and condition. Your technician will review findings and answer any questions before completing the visit.
Can AC maintenance help lower energy bills?
Proper maintenance helps your system run more efficiently by reducing strain and improving airflow. While results vary, many homeowners notice improved performance and more consistent cooling after service.
Do you service all AC system types and brands?
Yes. Harmony Heating & Air services all major air conditioning brands and system types, including traditional AC systems, heat pumps, and ductless mini-splits.
Do I need to sign up for a maintenance plan to get service?
No. AC maintenance can be scheduled as a one-time service. Some homeowners also choose ongoing maintenance options for added convenience, but there’s no requirement to enroll.
When is the best time to schedule AC maintenance in Charlotte?
Spring is ideal, before temperatures rise and systems are under heavy demand. Scheduling early helps ensure availability and prepares your system for Charlotte’s summer heat.
