| Check List | Benefit To You |
| Check refrigerant pressures. | A low or high charge can increase your operating costs and an improper charge can cause compressor damage. |
| Check and tighten electrical connections and wiring. | Loose connections can lead to motor or compressor failure. |
| Check and lube motors and bearings (if applicable). | Improperly lubricated rotating equipment will eventually fail. |
| Check volts and amp draw on electrical components. | High amperage readings can lead to major component failure. |
| Check outside coil conditions. | Dirty condenser coils raise refrigerant pressure higher than needed, increasing your electric bill. |
| Check noise and vibration levels. | Noise & vibration are generally a warning of future malfunction. |
| Check condensate line for drainage. | Algae can plug a condensate drain which can cause expensive water damage. |
| Check thermostat operations. | Units run longer than necessary with improperly calibrated thermostats. |
| Check safety controls. | Safety controls that do not function properly can increase operation costs and cause component failure. |
| Check air filter/replace as necessary. | A restricted air filter can cause your air conditioning unit to waste energy and shorten compressor's life. It can also restrict air flow throughout your home. |
| Check overall operation of system. | Ensures your system is in good operating condition. |
| Turn off humidifier (if requested). | Ensures that system is not humidifying during the cooling season. |

Air Conditioning Inspection
| Only |
| Check List | Benefit To You |
| Check superheat readings. | Improper superheat level can cause major system component damage. |

| Heat Pump Inspection | Only |
| Check List | Benefit To You |
| Check reversing valve operation. | An improperly operating reversing valve costs you $$. |
| Check defrost system operation. | An improperly functioning defrost system can cause compressor damage. |
| Check auxiliary heat. | Properly functioning auxiliary heat will keep you warn while your system is in a defrost cycle. |
| Visually inspect blower and assembly wheel. | A clean blower assembly moves proper heat. |

| Check List | Benefit To You |
| Check gas pressures. | Improper pressures can increase your operating costs. |
| Check for gas leaks. | Undetected gas leaks are dangerous. |
| Check for carbon monoxide leaks. | Carbon monoxide is a by product of inefficient combustion and is very dangerous. |
| Check inducer draft motor for proper venting. | Accumulation of gas can cause a catastrophic failure. |
| Check pilot and thermo coupling assembly (if applicable). | A weak and/or dirty pilot, as well as, a defective thermo couple will cause the furnace to shut down. |
| Check electronic spark ignition. | Spark failure will leave home unheated. |
| Check heat exchanger for leaks and cracks. | A leak in the heat exchanger puts you at risk of toxic fumes. |
| Check safety controls. | Safety controls that do not function properly can increase operation cost and cause component failure. |
| Check overall operation of the furnace. | Ensures your system is in good operating condition. |
| Check electrical wiring. | Loose connections can lead to motor or compressor failure. |
| Vacuum the main fire box and blower compartment. | Dirty compartments restricts air and causes your system to run inefficiently. |

| Furnace Inspection | Only |
| Check List | Benefit To You |
| Check and lube all motors and bearings (if applicable). | Improperly lubricated rotating equipment will eventually fail. |
| Check air filter/replace as necessary. | A restricted air filter can cause your furnace to waste energy and shorten it's life. It will also restrict air flow through out your house. |
| Check noise and vibration levels. | Noise and vibration are generally a warning of a future malfunction. |
| Turn on humidifier (if requested). | Convenience and quick check for problems. |

| Boiler Inspection | Only |
| Check List | Benefit To You |
| Check circular pump (if applicable). | An improperly functioning circular pump can increase your operating costs and cause damage to your system. |
| Check pressure relief valves. | Keeps your system from exploding and releasing hot water or steam. |
| Check zone valve operations. | Improperly functioning zone valves can increase your operating costs. |
| Check water and termperature pressure valves. | Keeps your system from exploding and releasing hot waer and steam. |
| Check expansion tank pressure and water level (if applicable). | Keeps your system from releasing hot water or steam. |
