We test the high-limit and rollout switches, confirm proper ignition and sequence, and check all safeties. We perform a carbon monoxide test at the supply and in ambient air, conduct a gas leak check at the gas line and valves, and confirm proper flue draft and venting to move combustion gases safely outdoors.

For natural gas furnaces, we clean and align the burners, set gas pressure and manifold settings, and inspect the heat exchanger for cracks. Where applicable, we inspect the pilot light and verify a strong flame signal at the flame sensor to maintain safe, consistent burner flames.

We measure supply and return air temperatures to confirm the correct temperature rise, check static pressure and airflow, and confirm blower speed settings. A full heating cycle test verifies that the system starts, runs, and shuts down correctly for peak efficiency.

We inspect wiring, electrical connections, capacitors, and contactors or relays, tightening lugs as needed. We record amp draw for the blower motor and inducer to spot stress before it causes costly repairs, and we verify the power switch and safety shut off switch operate correctly.

We clean the blower wheel when needed, inspect the blower compartment, and check blower shaft bearings and lubrication where applicable. We verify furnace filter size and replace the furnace filters to protect air quality and airflow through the return air duct.

We check the flue pipe condition and slope, inspect visible air ducts and connections for gaps, and service the condensate trap and lines on condensing units. Proper venting reduces exhaust gases in the home and supports the heating system’s efficiency.

We clean the burner compartment, vacuum the cabinet, and service the flame sensor and hot surface igniter. We wipe down exterior panels so you receive a clean furnace at the end of the visit.

We perform CO testing, inspect gas piping and the regulator for leaks, verify the emergency shutoff, and confirm adequate combustion air. Venting is checked at the flue pipe to move exhaust gases safely outdoors, and readings are documented for your service logs.

We inspect belts, bearings, and pulleys; confirm filter sizes and change cycles; test the economizer and calibrate dampers; and review coil condition with a cleaning plan. Drain pans and condensate lines are cleared so moisture drains correctly and indoor air quality is protected.

We examine contactors, sequencers or relays, control boards, and transformers; verify staging and heat strips where applicable; and test thermostat and network controls. Electrical connections are tightened, amp draws are recorded, and issues are flagged before they become costly repairs.

We measure temperature rise, check static pressure and airflow, and verify VFD operation when installed. Seasonal start up and shutdown procedures are completed so the heating system is ready for changing loads and colder weather.

We offer convenient windows, call or click scheduling, and reminder service before the heating season so you can schedule furnace maintenance at the right time. Members receive priority response and included tune-ups that help prevent emergency repairs and manage energy bills all winter.

Once per year before the heating season. Commercial and rooftop units may need seasonal or quarterly visits as part of a planned HVAC maintenance plan in Frankfort, IL.

Safety tests, cleaning, adjustments, electrical checks, airflow and temperature measurements, and a written report. Items include CO testing, gas leak checks, flame sensor cleaning, blower inspection, and filter check.

Yes. Gas furnace maintenance includes combustion, venting, gas valve and flue checks. Electric furnace maintenance focuses on heating elements, sequencers and relays, staging, and electrical connections.

Usually 60 to 90 minutes for residential systems. It can take longer if heavy cleaning is needed or if access is limited.

Most furnace manufacturers expect annual furnace inspections, professional service, and regular filter changes. Keep your receipts and the completed checklist.

Unusual noises or smells, short cycling, rising energy bills, weak airflow, uneven heat, frequent filter clogs, or burner flames that look unstable. If you suspect gas leaks or CO alarms, call a professional immediately.
