How a typical annual Comfort Plan-style visit proceeds
A structured visit reduces guesswork and ensures consistent service every year. The typical visit sequence:
- 1. Initial system inspection and customer interview
Technician checks recent performance notes and asks about any issues you have noticed.2. Indoor system service- Replace or clean filters.
- Inspect and clean evaporator coil.
- Check blower motor, wheel, and airflow.
- Clear around the unit.
- Clean the condenser coil and inspect fan blades.
- Test defrost controls and reversing valve.
- Tighten electrical connections and run amperage tests.
- Measure refrigerant pressures and temperature differentials.
- Calibrate sensors and test system response to thermostat inputs.
- Run the system through a complete cycle and record operational data.
- Provide a maintenance report with any recommended corrective actions.
Visits typically last between 60 and 90 minutes depending on system complexity. Records are maintained for every visit, providing a maintenance history that protects system health and warranty status.
Recommended frequency of maintenance
For Maple Valley homes, Green Head Heating recommends:
- At minimum: one comprehensive visit per year for systems serving mild-load properties.
- Preferred: two visits per year, timed for spring and fall, to prepare the system for heavy cooling or heating seasons.
- Additional checks: older systems, units that operate near capacity, or properties with pets/allergies may benefit from quarterly filter inspections.
Scheduling seasonal visits allows technicians to address cooling needs before summer and heating performance before winter, which is especially important in a climate with seasonal precipitation and pollen.
Ductless and mini-split specifics
Ductless and mini-split systems have unique maintenance needs:
- Indoor wall-mounted units require regular cleaning of filters and inlet grilles to maintain airflow and indoor air quality.
- Condensate pans and drains should be inspected and sanitized to prevent odors and microbial growth.
- Line sets and outdoor units get the same refrigerant and electrical checks as central systems, but technicians also verify mounting stability and insulation on refrigerant lines.
- Zoning controls and remote sensors are checked for correct operation.
Ductless systems are highly efficient when clean and properly tuned; recurring service keeps performance consistent and prevents uneven heating between zones.
Performance tests technicians perform and what they mean
Technicians use several noninvasive tests during maintenance to assess system health. These checks are explained in homeowner-friendly terms:
- Temperature split or delta T
- The difference between return air and supply air indicates how well the system transfers heat. A meaningful split shows efficient heat exchange.
- Refrigerant pressure readings
- Pressures in the system help determine whether refrigerant charge is within range. Low refrigerant can reduce capacity and cause icing; high refrigerant pressure can stress components.
- Amp draw and voltage measurement
- Measuring electrical current and voltage verifies motors and compressors are not drawing excessive power, which would indicate wear or electrical issues.
- Airflow measurements and visual inspection
- Proper airflow ensures rooms reach set temperatures efficiently. Blocked vents or dirty coils reduce airflow and performance.
- Defrost cycle verification
- The defrost cycle keeps the outdoor coil functioning in cold, wet conditions. A failed defrost cycle causes icing and reduced heating performance.
These tests allow technicians to prioritize repairs that deliver the biggest reliability and efficiency gains.
Troubleshooting signs and homeowner tips
Homeowners can spot early warning signs that a maintenance visit is needed. If you notice any of the following, schedule a service visit during the next maintenance window:
- Unusual noises like grinding, buzzing, or rattling coming from the outdoor unit or air handler.
- Uneven temperatures between rooms or slow recovery after a thermostat change.
- Increased utility bills without a change in habits.
- Moisture pooling near indoor units or water stains on ductwork.
- Short cycling where the system turns on and off frequently.
Simple homeowner maintenance between visits helps too:
- Check and change filters monthly during heavy use seasons.
- Keep at least 18 inches of clearance around the outdoor unit and remove leaves, grass clippings, and debris.
- Keep vents and registers open and unblocked.
- Ensure outdoor unit is on a stable pad and free of standing water in heavy rains.
These small steps reduce wear and help technicians focus on more technical adjustments during service calls.
