Outdoor components of a residential air-source heat pump
A heat pump is a device that transfers heat energy from a source of heat to what is called a heat sink. Heat pumps move thermal energy in the opposite direction of spontaneous heat transfer, by absorbing heat from a cold space and releasing it to a warmer one. A heat pump uses external power to accomplish the work of transferring energy from the heat source to the heat sink. The most common design of a heat pump involves four main components – a condenser, an expansion valve, an evaporator and a compressor. The heat transfer medium circulated through these components is called refrigerant.
While air conditioners and freezers are familiar examples of heat pumps, the term "heat pump" is more general and applies to many heating, ventilating, and air conditioning (HVAC) devices used for space heating or space cooling. When a heat pump is used for heating, it employs the same basic refrigeration-type cycle used by an air conditioner or a refrigerator, but in the opposite direction – releasing heat into the conditioned space rather than the surrounding environment. In this use, heat pumps generally draw heat from the cooler external air or from the ground.
In the heating mode, heat pumps are significantly more energy efficient than simple electrical resistance heaters. However, the typical cost of installing a heat pump is higher than that of a resistance heater.
What is Included in a Furnace tune-up service?
Whether you have a preventive maintenance plan or schedule a seasonal furnace tune-up, the tasks and purpose are the same. The purpose of preventive maintenance is to extend the lifespan of the heating system, avoid costly repairs, increase energy efficiency for lower utility bills and to keep you warm and cozy in your home. When you have a tune-up, there is a lot included in the service. You’ll find that service technicians arrive with a long list of items to inspect, test, adjust, clean and possibly replace if needed. On average, a tune-up takes about an hour and requires specialized equipment.
Tasks Service Technicians Perform During a Tune-Up
Typically, service technicians arrive with a minimum of 20-points to check during a tune-up. Here’s a list of some of the tasks that are performed:
·Safety: For safety, tests are run to check airflow for carbon monoxide and to check for natural gas leaks. All electrical wiring is tightened and inspected. Safety controls will also be inspected for proper operation.
·Mechanical Parts: All moving parts will be lubricated. Upper and lower combustion vents, burners, blower motor and blowout heat exchanger are thoroughly cleaned.
·Operations: The ignition system is tested for proper operation, and the temperature differences for supply and return registers are measured for proper function. Both the thermostat and thermostat contacts will be inspected for proper calibration and operation.
