What Affects the Efficiency of Your HVAC?

You want your HVAC in Kennesaw, GA, to keep you cool on those hot summer days and warm on those cold winter nights. You also want to keep your utility bills as low as possible. There are things you can do to make your HVAC unit work more efficiently. A good start is to become familiar with the top factors affecting the efficiency of your HVAC system.


Close Up HVAC Unit The Size of Your HVAC Unit

For your HVAC unit to work efficiently, it needs to be the right size for your house. If the HVAC unit is too big, you use energy you don't need. If it's too small, the unit works too hard to heat or cool the house.


Energy Ratings

The energy ratings of HVAC units make a difference. An air conditioner has a Seasonal Energy Efficiency Ratio (SEER) rating, and a furnace has an Annual Fuel Utilization Efficiency (AFUE) rating. A heat pump has both a SEER rating and a Heating Seasonal Performance Factor (HSPF). The higher the SEER, AFUE, or HSPF, the less energy the unit or pump uses to heat or cool a home.


The Age of Your HVAC Unit

The age of your HVAC affects its efficiency. Over the past couple of decades, manufacturers, in response to federal regulations, have made their HVAC units more efficient. If your unit is over 20 years old, your energy costs are probably higher than they should be. Consider replacing your unit. You'll recoup some of the money you spend on a new unit in lower energy costs.


If your unit is between 10 and 15 years old, contact HVAC professionals to see if there are parts that can be replaced or repairs that can be made to improve your unit's efficiency. Before spending a lot of money on replacement parts and repairs, consider the advantages of buying a new, more efficient unit.


Thermostat Setting

The lower your thermostat setting, the more energy your air conditioner will consume. Use a programmable thermostat so you can conserve energy, for example, by having the temperature higher until you are about ready to return home.


Thermostat Fan Setting

You should set your HVAC system on the automatic fan setting. When your unit is on the manual setting, the fan circulates air whether or not your system is cooling or heating. This will cause your energy bills to be higher and your filters to clog quicker. When on the automatic fan setting, the fan turns on when your unit is heating or cooling. You save on your energy costs and you don't have to change your filters as often.


Indoor Air Quality

When dust and debris move into your HVAC system's air filters, the system works harder and is less energy efficient. Using an air purifier or ventilator can help keep your indoor air cleaner and your HVAC system working more efficiently.


HVAC Maintenance

Regular maintenance of your HVAC system can increase its efficiency. Have HVAC professionals check your unit twice a year—in the spring and again in the fall. HVAC professionals can catch small problems and repair them before they become big problems requiring a major repair or a new unit. Dirty coils can be cleaned, or a duct leak can be sealed, resulting in your unit working more efficiently.
