What to Expect During a Satterlee HVAC Tune-Up

Many homeowners schedule annual HVAC tune-ups because they know it's good practice — but aren't sure exactly what a technician does during those visits. Here's a transparent look at what Satterlee's technicians check during a standard maintenance appointment, and why each step matters.

Air Filter Inspection and Replacement

We start with the air filter. A clogged filter is one of the most common causes of HVAC inefficiency and premature wear. We'll inspect your current filter and replace it if needed. We'll also discuss the right filter type for your system and your household's needs.

Thermostat Calibration

We verify that your thermostat is reading temperatures accurately and communicating correctly with your system. An uncalibrated thermostat can cause the system to run longer than necessary or fail to maintain the set temperature, wasting energy and reducing comfort.

Electrical Component Inspection

We inspect and tighten all electrical connections, check voltage and current on motors, and test capacitors and contactors. Loose or failing electrical components are a common cause of system failures — catching them during maintenance prevents a breakdown later.

Refrigerant Level Check

For cooling systems, we check refrigerant levels and inspect for leaks. Low refrigerant reduces cooling capacity, causes the system to work harder, and can eventually damage the compressor — the most expensive component in the system.

Coil Cleaning

We clean both the evaporator coil (indoor) and condenser coil (outdoor). Dirty coils reduce heat transfer efficiency, meaning the system has to run longer to achieve the same result. Regular cleaning can improve efficiency by 5–15%.

Blower Motor and Belt Inspection

We inspect and lubricate the blower motor and, where applicable, check belt tension and condition. A failing blower motor or a worn belt can significantly reduce airflow and comfort throughout the home.

Safety Control Testing

We test all safety controls and shutoffs to make sure they function properly. This includes checking the heat exchanger on furnaces for cracks, which can allow dangerous combustion gases including carbon monoxide to enter the living space.

System Performance Report

At the end of the visit, we'll review our findings with you, explain anything that needs attention, and provide a written summary. We believe in transparent communication — you'll always know exactly what we found and what your options are.
