Does Dallas Homeowners Can Save Money Using Central Air Conditioner?

In the typical home, air conditioning uses more electricity than anything else—16% of total electricity used.  In warmer regions AC can be 60-70% of your summer electric bill. This is where the savings are folks, not in worrying that you left your cell phone charger plugged in too long.

Make sure your central air conditioner is ready for cooling season.


How to Maintain an Air Conditioner

Central air conditioners have two separate components: the condenser and the evap­orator. The condenser unit is usually located outside the house on a concrete slab. The evaporator coil is mounted in the plenum or main duct junction above the furnace.

Most central air conditioners are connected to a home’s forced-air distribution system. Thus, the same motor, blower, and ductwork used for heating are used to distribute cool air from the air conditioning system. When a central air conditioner is operating, hot air inside the house flows to the furnace through the return-air duct. The hot air is moved by the blower across the cooled evaporator coil in the plenum and is then delivered through ducts to cool the house. When the air conditioner works but the house doesn’t cool, the problem is probably in the distribution system.

In most homes, central air conditioners work together with an existing forced-air system to cool and circulate air.  The air is cooled when it passes over the central air conditioner’s evaporator coil, which is the main component of the system located inside the house.  The cooled air then travels through the ducts into the home while room-temperature air is pulled into the furnace’s return air duct, beginning the cycle again.

The condeser unit, which is located outside the home, is the other main component of the central air conditioning system.  Both the evaporator coil and condenser are sealed systems, and require servicing by a professional technician.  However, homeowners can perform some basic air conditioner maintenance that can keep the system’s components clean and functioning properly.

A central air conditioner is part of your home’s heating and cooling system. A central air conditioner is a closed loop system, and the specific components that make up the central air conditioning portion of your heating and cooling system include a condenser (outside) and an evaporator (inside).

The condenser contains a compressor, coils, and fins. Piped refrigerant is compressed under high pressure and temperature in the compressor and then travels as a  superheated vapor into the coils. It expands into a cool, low-pressure gas as it enters the evaporator, which is located on the supply side of a furnace, within the plenum. After warm air from the return side is filtered, the furnace blower directs air over a chilled evaporator. This supplies cooled, conditioned air to rooms within your home.

With proper maintenance, a new air conditioner should last 12-15 years, and can last much longer than that in some cases. With central air and/or window units it’s not only important to have routine maintenance performed on them, but to also use other features that will help you’re A/C run even better. Below are some maintenance tips, followed by some suggestions that will keep your unit from working too hard.


Whether you realize it or not, your home’s heating and cooling system has a profound impact on your overall comfort and day-to-day activities. During the winter months, your heating system ensures that you are immune from the harsh cold and bitter temperatures, and throughout the summer, nothing feels quite as nice as walking into a house kept cool after a day of sweating outside.
