Overland, MO Heating & Air Conditioning Installation, Repair & Maintenance

Responded to no cooling complaint on 15-year-old ground-level unit that had received maintenance service days prior. Upon inspection, discovered extensive ice formation on evaporator coil and refrigerant lines, indicating restricted airflow rather than low refrigerant charge. Found evaporator coil heavily contaminated with dust and debris buildup between fins, preventing adequate air circulation across heat exchanger. Documented frozen coil conditions with significant frost crystallization on copper suction line and coil surfaces. System shut down to allow complete ice melt before further diagnosis. Identified restricted airflow as root cause of warm air complaint, requiring coil cleaning and possible blower motor evaluation to restore proper system operation.

Responded to report of water pooling near furnace in basement. Upon arrival, conducted thorough inspection of unit and surrounding area, including structural components and drainage systems. Documented conditions with photographs showing wooden floor joists, foundation walls, and stored materials in vicinity of HVAC equipment.

Responded to no-cool complaint on residential split system installed circa 2008. Previous contractor had replaced control board following power surge, but outdoor compressor remained non-operational. Upon arrival, confirmed outdoor condensing unit not running while indoor blower operated normally. Performed diagnostic testing on electrical components and compressor contactor. Found compressor electrically locked, likely damaged during initial power surge event when unit reportedly ran without condenser fan, causing frost formation on coils. Verified compressor windings showed abnormal resistance readings and would not start under load. Recommended compressor replacement due to internal failure from electrical damage sustained during power surge. Indoor evaporator coil showed moderate dust accumulation and drain pan exhibited biological growth and mineral deposits, requiring cleaning during future maintenance. Documented equipment condition with photographs for records.

Responded to no cooling complaint on 2-year-old system experiencing intermittent shutdowns. Upon inspection, discovered severely restricted airflow due to heavily soiled evaporator coil, as evidenced by visible dirt buildup and wave patterns across coil surface. Advised unit shutdown to prevent compressor damage and recommended immediate coil cleaning with repairs as necessary to restore proper system operation and cooling capacity.

Completed preventive seasonal cooling checkup on 4-year-old single outdoor condensing unit located in backyard. Performed comprehensive U10 cooling tune-up protocol including inspection of blower motor assembly, electrical connections, and ventilation components. All colored wiring connections verified secure, airflow pathways confirmed unobstructed through louvered grille system, and unit interior inspected for proper operation with standard dust accumulation noted for equipment age.

Responded to service call for 8-year-old residential air conditioning unit that would not shut off, causing excessive cooling despite thermostat set to 80 degrees. Upon arrival, confirmed thermostat display showed cooling mode active with set point at 80 degrees while actual temperature read 78 degrees, yet system continued running. Diagnosed faulty thermostat unable to properly signal compressor to cycle off when temperature setpoint was reached. Recommended thermostat replacement to restore proper temperature control and prevent continuous system operation.

Responded to no cooling complaint on 10-year-old residential air conditioning system. Upon arrival, connected refrigerant manifold and micron gauge to condenser unit to perform diagnostic testing of system pressures and temperatures. Measurements indicated abnormal operating conditions requiring further evaluation and potential repairs to restore proper cooling function.

Responded to callback for thermostat malfunction following new air conditioning installation. Upon inspection, identified that the RC/RH jumper wire had not been cut per manufacturer specifications for dual-transformer systems, causing improper voltage distribution to the thermostat terminal block. Removed jumper as indicated by installation instructions, verified proper wiring connections at all terminals (RC, RH, O/B, Y, G, W, C), and confirmed system functionality with successful heating and cooling cycles.

# HVAC Tune-Up Completed Performed comprehensive preventive maintenance tune-up on Rheem air conditioning unit located at front of property per Home Depot work order F59860966. Conducted electrical diagnostics using digital multimeter to verify voltage readings (5.02V measured) on control board, capacitor, and wiring harness connections. Inspected blower wheel assembly and squirrel cage fan for debris accumulation and proper operation. All electrical components, including relays, capacitors, and wire connections, were tested and found functioning within normal parameters. Unit operational and ready for cooling season.

Responded to callback for humidity and cooling issues on newly installed system. Inspected Lennox S40 smart thermostat operation and verified system notifications were cleared with no active alerts. Examined air return grille and noted dust accumulation on louvers that could restrict airflow and impact system performance; recommended cleaning to optimize air circulation and system efficiency.

Responded to no-cooling complaint on residential outdoor unit over 10 years old. Upon arrival, found unit blowing warm air as reported. Performed diagnostic testing with multimeter on condenser components to identify system failure. Accessed internal components by removing top panels and tested electrical systems and refrigerant circuit. Unit showed signs of age-related wear and required repair to restore cooling function.

Responded to no-cool call on 10+ year old residential AC unit experiencing loud humming noise and failure to reach set temperature. Upon arrival, found unit had been turned off per prior instruction. Performed diagnostic evaluation of system components including evaporator coil, ductwork connections, and refrigerant lines in attic space. Identified excessive condensation on supply ductwork and inspected blower motor operation, electrical connections, and capacitor function. Documented system condition with photos showing HVAC infrastructure, insulated plenum assembly with flexible duct connections, and moisture accumulation on metal ductwork indicating potential airflow or humidity issues.

Completed sewer lateral repair under City of Overland permit PSL26-0028, permit # PP26-0228. Excavated trench to access existing sewer line, installed new PVC piping with proper fittings and connections to restore functionality.
