5 Factors Affecting Your HVAC Efficiency

Air Conditioners Do you think your HVAC system could be more efficient at heating and cooling your home? You’re not alone in these thoughts. In fact, homeowners contact local HVAC techs for air and heating replacement in Alpharetta because they’re looking for better performance. Before you decide to do something as expensive as replacing an entire heating and cooling system, it’s a good idea to learn more about what affects the efficiency of your unit. Some simple adjustments could save you money on your energy bills and help you avoid the expense associated with replacing the unit.

Manual vs. Automatic Fan Settings

A/C and heating systems in Alpharetta have two fan settings, manual and automatic. The automatic setting turns on when the unit turns on. However, some people prefer to use the manual setting, which keeps the fan blowing even when the unit’s not heating or cooling. People choose the manual setting because they believe it gives them even heating and cooling and that it makes the unit work less. The truth is that when the fan is in the manual mode it’s constantly drawing energy. It’s also constantly circulating the air in the home and drawing dirt, dander, and other debris into the air filter, which puts a strain on the unit. If your HVAC system is working well, but you want to lower your energy usage, keep the fan set to the automatic mode.

Sizing

Is your HVAC system the right size for your home? Improper sizing leads to inefficient results. When a unit is too big for the home, your using energy you don’t need to use. It’s a waste of money. Homes that have units that are too small often need more cooling and heating repair services in Alpharetta because the unit has to work harder to achieve optimal results. When it’s time to replace your HVAC unit, make sure to work with professionals who understand the importance of proper sizing.

Ratings

ThermostatAll heating and cooling systems are assigned energy ratings. If you’re in the market for a new HVAC system, pay close attention to the Seasonal Energy Efficiency Ratio (SEER) for air conditioners. For furnaces, you want to know that the Annual Fuel Utilization Efficiency (AFUE) rating. Ideally, you’re looking for a higher number. The higher the rating, the less energy the unit uses to heat and cool the home. If you’re installing a heat pump, you’ll look at the SEER rating and the Heating Seasonal Performance Factor, HSPF.

Traditional heating systems work well for most homes, but if you’re looking for improved efficiency consider installing a heat pump. Depending on the type of heat pump you install, electric vs. geothermal, you can use little to no energy.

The Unit’s Age

How old your unit is has a lot to do with its efficiency. Over the last couple of decades, manufacturers have responded to federal regulations to make units more energy efficient. Therefore, if you have an HVAC system that is older than 20 years old, it’s highly likely that it’s not saving you any money. It’s an energy sucker.

If you have a unit that’s 10 – 15 years old and you’re concerned about efficiency, contact HVAC professionals. Often, cooling and heating unit repair in Alpharetta is effective at improving efficiency problems.

Maintenance

Lastly, make sure that you stay on top of maintenance. Taking care of small problems always improves efficiency. Contact Cool Air Mechanical for cooling and heating maintenance in Alpharetta.
