See for yourself the details of the most comprehensive Tune-up/Check-up in the industry.
- Check thermostat — Improperly calibrated thermostat affects comfort and operating costs.
- Start unit — Verify unit is operational before tune-up takes place.
- Check return air filter — A restricted filter causes unit to waste energy
- Routine cleaning of evaporator coil** — A dirty evaporator coil decreases efficiency and can lead to compressor failure.
- Check condensate pan and fittings for leaks — A cracked pan or loose fittings can cause expensive water damage.
- Check condensate drain** — A plugged condensate drain can cause expensive water damage.
- Check blower motor amp draw — Ensures optimum performance; protects equipment.
- Check blower wheel — A dirty blower wheel reduces airflow; increases operating costs and can lead to compressor failure.
- Check blower motor stability — Unstable blower motors can cause premature failure of the motor and damage to the system.
- Lube motors & bearings — Improperly lubricated rotating equipment will eventually fail.
- Check belt, pulleys and alignment — Avoids costly service calls, saves money on utility costs.
- Examine all electrical connections — Extends life of system; ensures safety.
- Check total electrical consumption — Ensures optimum performance; protects equipment.
- Check unit disconnect switch — Worn, overheated disconnect blows fuses; potentially dangerous
- Examine parts for visible wear — Avoids costly service calls.
- Check temperature difference across coil — Temperature difference can indicate proper cooling of system. Also affects comfort level.
- Remove debris around outside unit — Promotes efficiency. Prevents damage to equipment.
- Routine cleaning of condenser coil — Dirty condenser coils raises refrigerant pressures increasing electrical costs.
- Check condenser fan motor amp draw — Ensures optimum performance; protects equipment.
- Check condenser fan motor stability — Prevents costly service calls.
- Check condenser fan blades for vibration — Prevents damage to unit and costly service calls.
- Check crankcase heater* — Crankcase heaters that do not work lead to compressor failure.
- Check reversing valve* — Improperly operating reversing valve wastes energy.
- Check relays & contactors — Worn contactors and loose connections can lead to motor and compressor failure.
- Check capacitors — Bad capacitors lead to compressor and motor failure.
- Test time delay — Prevents unit from starting under load when power has been temporarily interrupted.
- Check defrost assembly* — A defrost timer that does not work correctly causes loss of heat and can shorten life of compressor.
- Check all controls — Extends the life, saves money, and prevents failure.
- Check all safety devices — Keeps unit in safe operating condition.
- Measure operating pressures with gauges — Improper refrigerant charge can reduce cooling capacity and efficiency.
- Test refrigeration metering device — Blockage or improper operations of metering device reduces cooling capacity, increases fuel costs, and shortens system life.
- Check compressor amp draw — Ensures optimum performance, protects equipment.
- Check noise and vibration levels — Increases comfort & extends life of equipment.
- Check and secure all panels — New systems have a blower door safety and will not operate if door is not properly in place.
- Wax outdoor unit** — For weather protection and extended life.
- Check water temperatures*** — Water temperatures are very important to the operation of the unit.
- Check water flow*** — Proper water flow is vital to system operation.
- Record System operation — For Homeowner’s information and records.
- Make final operations test — To ensure system operation.
- Explanation of tune-up results — Explanation of work performed in tune-up and results.
- Advise improvements as needed — To allow you to gauge effectiveness, efficiency and potential need for repair or replacement.
- Conclude Transaction — Answer questions, collect for work performed, signature(s) on invoice, leave customer copy of tune-up, make appointment for any additional work required.
