• Gas furnaces
• Focus on burner and ignition system inspection, heat exchanger inspection for cracks, combustion analysis where required, and flue vent integrity.
• Carbon monoxide safety checks and gas pressure verification are included where applicable.
• Ductless mini-splits
• Clean indoor and outdoor units, check refrigerant lines and insulation, inspect drain lines, and verify remote sensors and controls.
• Ductless systems can accumulate dust and allergen loads in indoor units during smoky summers, so filter and coil cleaning is critical.
• Hybrid and variable-speed systems
• Verify control logic, inspect variable-speed motors and inverters for error codes, and confirm correct staging and modulation.
• These systems deliver efficiency gains when maintained to manufacturer tolerances.
• Older equipment and legacy systems
• Inspect for worn components and safety risks, document inefficiencies, and prioritize repairs to prevent breakdowns.
• Tune-ups for older units often uncover small issues that, if left unattended, lead to major failures in extreme weather.

Diagnostic checks and performance measures technicians use

A thorough tune-up includes measurable checks that go beyond visual observation. These diagnostics quantify system health and allow technicians to recommend targeted repairs.

• Refrigerant pressure readings: confirm correct charge relative to ambient conditions.
• Amp draw and voltage readings: compare motor current and voltage to rated values to detect motor or capacitor problems.
• Temperature split (delta T) across evaporator: typical ranges indicate proper heat transfer and airflow.
• Static pressure and airflow: measured when necessary to detect duct restrictions and blocked filters.
• Combustion analysis for gas systems: measures combustion efficiency and checks for unsafe exhaust conditions.
• Condensate flow inspection: ensures unobstructed drainage and functioning traps.
• System runtime analysis: identifies short cycling or excessive run times that indicate underlying issues.

These diagnostics help prioritize which items need repair immediately and which can be managed as part of regular maintenance.

Seasonal timing for tune-ups in Sammamish

Timing tune-ups to seasonal demands maximizes equipment readiness and efficiency.

• Spring tune-up (ideal for cooling)
• Schedule before the first consistent warm days so air conditioning or heat pump cooling is ready.
• Spring service in Sammamish also addresses pollen and dust build-up from wakes of spring growth.
• Fall tune-up (ideal for heating)
• Complete before the first sustained cold and rainy stretch to ensure safe and reliable heating through the wet months.
• Fall inspections emphasize condensate, flue integrity, and heat exchanger condition for furnaces.
• Heat pump owners
• Consider semi-annual tune-ups because heat pumps operate year-round as both heating and cooling systems in the Pacific Northwest climate.
