- Use a multimeter to check voltage, current draw, and continuity on motors, contactors, capacitors, and control circuits
- Test safety switches, flame sensors, and limit switches in furnaces
- Inspect and test relays, transformers, and control boards
Refrigerant and pressure diagnosis
- Attach refrigerant gauges to check pressures and compare to manufacturer specifications and ambient conditions
- Look for signs of leaks: oil stains, hissing, UV dye, or low-side pressure anomalies
- Evaluate the evaporator and condenser coils for restrictions and airflow problems
Combustion and safety checks (for gas furnaces)
- Conduct combustion analysis and check venting for proper exhaust flow
- Test for carbon monoxide risks and gas leaks with appropriate detectors
- Inspect heat exchanger condition for cracks or severe corrosion
Ductwork and airflow assessment
- Assess static pressure, supply and return balance, and isolated airflow problems in specific rooms
- Inspect duct joints, insulation, and accessible returns for leakage
Compile findings and produce a clear, written estimate
- Provide a line-item diagnostic report showing failed components, safety issues, recommended repairs versus replacement options, expected outcomes, and warranties for parts and labor
Common HVAC repairs and realistic solutionsThis section describes typical repair actions and what homeowners and small business owners in Westerville can expect as solutions.
Air conditioner and heat pump repairs
- Refrigerant leak repair and recharge: Locate leak source, repair by brazing or replacing affected components, evacuate and recharge to correct levels, then test for proper pressure and temperature.
- Compressor or condenser motor replacement: When the compressor or outdoor fan motor fails, technicians replace the failed unit with a properly sized component and verify starting capacitors and contactors.
- Capacitor and contactor replacement: These small, inexpensive parts frequently cause hard-start or no-run conditions. Replacing them often restores reliable operation.
- Refrigerant metering device repair: Replace malfunctioning TXV or piston metering device to restore correct refrigerant flow and superheat.
- Coil cleaning and access panel repair: Dirty evaporator or condenser coils reduce heat transfer. Professional cleaning and restoring proper airflow can recover efficiency and capacity.
- Reversing valve or defrost control fixes on heat pumps: Correcting defrost circuit issues prevents excessive frost buildup and loss of heating performance.
Furnace and heating repairs
- Ignition system repair or replacement: Replace malfunctioning ignitors, flame sensors, or gas valves to restore reliable ignition.
- Blower motor and belt repairs: Replace worn motors, bearings, or belts and balance blower assemblies to restore airflow and reduce noise.
- Limit switch or control board repair: Replace failed safety switches or control boards that cause nuisance shutdowns.
- Heat exchanger evaluation and replacement recommendations: If a crack or irreparable corrosion is found in the heat exchanger, replacement of the furnace is typically the recommended safety action.
Electrical and control repairs
- Replace failing capacitors, contactors, and relays
- Repair/replace thermostat wiring and digital controls, including programmable and smart thermostats
- Repair transformer failures and correct low-voltage circuit issues
Ductwork and airflow repairs
- Reseal or reconfigure duct joints to recover lost static pressure and improve balance
- Add or repair return grills and pathway improvements for better airflow
- Recommend improvements like additional returns, upgraded insulation, or localized dampers for zoning
Parts replacement, warranties, and quality considerations
- Parts selection: Technicians use manufacturer-recommended parts or equivalent OEM-quality components to ensure compatibility and longevity.
- Warranties: Repairs typically come with documented warranties on parts and workmanship. Best Service Heating & Cooling documents warranty terms and registers manufacturer warranties when applicable.
- When to replace instead of repair: If repairing an older system will not provide satisfactory efficiency, safety or lifecycle value, technicians present replacement options with comparisons between repair cost, estimated remaining life, and long-term operating costs.
Safety and performance checks included with repairSafety and proper system performance are verified before any job is considered complete. Standard checks include:
- Carbon monoxide testing for combustion appliances and verification of proper venting
- Gas line leak checks and gas pressure validation
