Inspected the return air filter housing and verified the installed 20x25x1 pleated filter was clean and properly seated, with no restriction to airflow. System was found in good operating condition with no deficiencies requiring repair.

Performed a complete furnace tune-up on a 5-year-old unit, including inspection of the cabinet, vent louvers, and associated components, which were found clean and intact with no visible rust, cracks, or frost. Measured electrical performance with a true RMS clamp meter, recording a stable 2.82 A AC draw to verify proper component operation. Unit was left in good working condition and enrolled in the recurring furnace maintenance plan.

Responded to a no-heat call on the downstairs furnace, which was cycling on and shutting off after a few minutes. Inspected the equipment, flue and vent piping, and air handler, and removed the filter to check airflow, finding it clean and free of obstruction. Completed a service evaluation under the service contract and documented the system's condition with photos.

Replaced the heat exchanger and burner assembly in the Trane gas furnace using pre-staged parts. Reconnected the gas valve, manifold, inducer, pressure switch, and wiring, then verified proper gas flow and burner operation with a handheld meter. The furnace was left in working condition with no visible damage or abnormal conditions.

Performed a full tune-up on two 7+ year-old furnaces, including inspection of the burner assemblies, wiring harnesses, control boards, and condensate/PVC piping. Burner components showed heat discoloration and residue buildup consistent with age, and the pleated filter media was found with light dust accumulation but no tears, rust, or frost. Cleaned and serviced the equipment to restore proper combustion and airflow, and verified safe, normal operation on both units.

Completed comprehensive BFMA tune-up on 15-year-old furnace system located in basement. Performed standard maintenance protocol including full system inspection, burner assembly cleaning, heat exchanger examination, and electrical component testing using digital clamp meter to verify proper amperage draw. Evaporator coil displayed significant frost and ice accumulation indicating potential airflow restriction or refrigerant issue requiring monitoring. All gas connections, piping, and electrical wiring inspected and confirmed secure with no immediate safety concerns identified.

Completed full HVAC system estimate following diagnosis of cracked heat exchanger resulting in no heat condition. Evaluated existing outdoor condensing unit installation and electrical service panel capacity to determine proper equipment specifications for complete system replacement including furnace and air conditioning components. Documented current equipment location, utility connections, refrigerant line routing, and electrical infrastructure to ensure accurate proposal for Lennox EL297 high-efficiency furnace paired with either EL16 or EL18 air conditioner model based on homeowner comfort requirements and system compatibility.

Completed comprehensive BFMA tune-up on 13-year-old furnace system including full inspection, combustion analysis, and cleaning of burner assembly components. Replaced 16x25x5 air filter and installed new #35 humidifier pad as part of semi-annual maintenance service. All equipment tested and operating within manufacturer specifications upon completion.

Completed comprehensive BFMA tune-up on residential split system with basement-mounted furnace and air handler. Performed full system inspection, verified operational parameters, cleaned condensate drain lines, checked refrigerant levels, tested thermostat functionality, and inspected ductwork connections. Documented equipment age and model information for new homeowner's service records, as system history was unknown at time of membership transfer.

Completed comprehensive BFMA tune-up service on two residential Lennox air conditioning systems. Performed standard maintenance procedures including inspection of outdoor condensing units, cleaning of condenser coils showing dirt accumulation and environmental debris, verification of electrical connections at disconnect box, assessment of refrigerant levels, and testing of system operations. Both units operational and running within manufacturer specifications upon completion.

Completed comprehensive BFMA tune-up service on residential HVAC system with equipment age of 1+ years. Performed standard air conditioning maintenance protocol including system inspection, replaced heavily soiled air filter with significant dust and debris accumulation, and verified proper operation of all components. System is now operating efficiently with improved airflow following filter replacement and routine maintenance procedures.

Responded to no cooling call on one-year-old Goodman residential system that had been previously serviced 4-5 times by installing contractor without resolution. Upon inspection, discovered evaporator coil completely frozen with extensive ice buildup on refrigerant lines and surrounding surfaces. Identified restricted airflow as root cause due to severely clogged air filter and inadequate return air, causing coil temperature to drop below freezing point. Shut down system to allow coil to thaw completely, replaced air filter, verified proper airflow across evaporator, and checked refrigerant charge levels. Once thawed, restarted system and confirmed proper operation with adequate cooling and no further ice formation. Educated homeowner on importance of regular filter changes and proper system maintenance to prevent recurrence.
