Practical preventive care

More than a quick look at the unit.

John Calhoun Electric & HVAC provides AC maintenance and tune-ups for homeowners throughout Roanoke, VA and nearby communities. Our team services central AC systems, heat pumps, mini-splits, and other cooling equipment.

We check the parts that affect cooling, airflow, drainage, electrical operation, and overall system performance.

Maintenance will not stop every AC problem. It does catch most of the common ones before they turn into a breakdown.

Why maintenance matters

Many AC problems start small.

Our work records show poor cooling and shutdowns tied to dirty coils, clogged drains, bad filters, weak capacitors, and low refrigerant. Regular maintenance gives us a chance to look for those problems before the system stops working on a hot day.

That means fewer surprise calls and a better shot at getting through August without one.

A thorough system check

What we check during an AC tune-up.

Outdoor Coil

We inspect the outdoor coil and clean it so the system can dump heat.

Indoor Coil

We check the evaporator coil for dirt and buildup that chokes airflow.

Condensate Drain and Trap

We check the drain and trap so water runs off instead of tripping the float switch.

Air Filter and Airflow

We check filter condition, installation, and signs of restricted airflow that make the system work harder.

Refrigerant Operation

We check how the system runs and watch for refrigerant that is off.

Electrical Components

We inspect capacitors, contactors, wiring, motors, and controls for wear, looseness, damage, or abnormal operation.

Motors and Moving Parts

We check indoor blowers and outdoor fans and listen for unusual noise or poor performance.

Supply and Return Temperatures

Temperature readings help show whether the system is removing heat from the home as expected.

Overall System Operation

We confirm that indoor and outdoor equipment starts, runs, and shuts down properly and look for other repair needs.

Maintenance timing

How often should your AC be serviced?

Older equipment, hard use, pets, and a history of drain trouble all mean you want it looked at more often.

A heat pump runs all year, so it earns two visits. Once before cooling season and again before heating season. Learn more about our heat pump services.

If we turn up a problem, we tell you whether it is an AC repair or, on older equipment with a major failure, time to talk about AC installation and replacement.
