Section Off Unused Areas And Maintain The System. When heating or cooling, ensure vents and thermostats in unoccupied areas are sectioned off to avoid energy waste. Air conditioning is not recommended in areas that don't need it, such as most storage rooms. .

Install a Thermostat. Programable thermostats can be used to automate HVAC systems. You can program the thermostat to ensure the HVAC system turns on half an hour before arrival and turns the system off half an hour before leaving. .

Adjust The Temperature With The Season. For maximum comfort, the thermostat should be set between 73.5-77°F in summer and 64.5-70°F in winter. .

Other Considerations. The obvious ones -- initial cost, warranty, sound ratings, quality of construction, and manufacturer reputation. The better manufacturers today have a product for each price range to accommodate different consumer priorities. Warranties and sound ratings tend to parallel the cost of the product. The wiser manufacturers don’t lessen the quality of the product components to get to the lower price bracket. Rather they simply deduct features.

The Science behind it. The refrigerant, like most substances, expands when it is heated and contracts when it is cooled. The refrigerant is specially selected for its ability to transfer heat. It is especially well-suited to absorbing heat and expanding and then giving off this heat when exposed to cooler air and compression. .

Air conditioning system's components. Air conditioning systems were once considered a luxury item in the old days! It wasn’t until the 1950’s that they became more common in homes. Today, it’s hard to image living without a comfort system of some sort in your house. Over the decades, air conditioners have changed to become more efficient and environmentally friendly. But, they still have the same basic components (compressor, evaporator coil, condenser coil, and a metering device) from decades past.
