HVAC & Plumbing Maintenance Inspection Checklists

A typical plumbing inspection in a home involves a thorough check of the home’s entire plumbing system to ensure everything is functioning properly and there are no leaks, blockages, or potential issues. Here’s what a plumber usually checks during an inspection:

• Water Supply Lines: Inspect for any leaks, corrosion, or damage in the water supply lines that bring water into the home.
• Faucets and Fixtures: Check all sinks, faucets, showers, and bathtubs for leaks, proper water pressure, and signs of corrosion or wear.
• Water Heater: Inspect the water heater for leaks, proper venting, signs of rust or corrosion, and ensure that the temperature settings are correct.
• Toilets: Ensure that toilets are flushing correctly, check for leaks around the base, and inspect the internal components for proper functioning.
• Drainage System: Check for proper drainage in all sinks, tubs, and showers, ensuring there are no clogs or slow drains.
• Water Pressure: Test the overall water pressure to make sure it is within a normal range and not too high, which can cause leaks.
• Exposed Pipes: Inspect any exposed plumbing pipes (in basements, crawl spaces, or under sinks) for leaks, corrosion, and proper insulation.
• Garbage Disposal: Check the function and condition of the garbage disposal if present.
• Valves and Shut-offs: Ensure that all shut-off valves for water supply lines (such as under sinks, toilets, and the main water shut-off) are functional and accessible.

A plumbing inspection helps to catch small issues before they become costly repairs and ensures that the home’s plumbing system operates safely and efficiently.

A 21-point HVAC inspection typically involves a thorough check of both the heating, ventilation, and air conditioning systems to ensure they are operating efficiently and safely. Here’s a simplified breakdown:

• Thermostat Check: Ensure the thermostat is set correctly and responds properly.
• Air Filter Inspection: Check if the air filter is clean or needs replacing.
• Electrical Components: Inspect electrical connections for wear or loose connections and check capacitors, relays, and wiring.
• System Controls: Test the start cycle, heating, cooling, and shutdown sequence.
• Refrigerant Levels: Measure and ensure proper refrigerant levels.
• Condenser Coils: Check for dirt or debris and recommend cleaning if necessary.
• Evaporator Coils: Inspect for cleanliness and blockages; recommend cleaning if necessary.
• Drain Lines: Check for clogs or leaks in the condensate drain lines.
• Airflow: Ensure proper airflow through ducts and vents.
• System Efficiency: Evaluate how efficiently the system is heating or cooling.
• Insulation: Inspect insulation on ducts and refrigerant lines.
• Fan and Blower: Test the operation and cleanliness of fans and blower motors; recommend cleaning if necessary.
• Heating Elements: Check for signs of wear or malfunction in heating elements.
• Gas Connections (for gas systems): Inspect for gas leaks or signs of corrosion.
• Burners (for gas systems): Check for proper burner flame and cleanliness.
• Heat Exchanger (for gas systems): Inspect for cracks or signs of damage.
• Vents and Ducts: Check for obstructions, leaks, or damage in vents and ducts.
• Outdoor Unit (for AC systems): Inspect the outdoor unit for debris, damage, and general condition.
• Safety Controls: Ensure all safety switches and controls are operational.
• System Efficiency: Measure overall system efficiency and performance metrics.
• Documentation and Recommendations: Provide a detailed report of findings and any recommendations for repairs or maintenance.
