Best energy efficiency auditors near Scott, LA

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

Homeowners may qualify for an HVAC tax credit if they install an ENERGY STAR®-certified HVAC system that exceeds the energy efficiency minimum standards:

• Split-System AC: 16 SEER2

• Packaged AC: 15.2 SEER2 and 11.5 EER2

• Ducted Split Heat Pump: 15.2 SEER2, 7.8 HSPF2, and 11.7 EER2 

• Packaged Heat Pump: 15.2 SEER2, 7.2 HSPF2, and 10.6 EER2

• Mini-Split System: 16 SEER2, 9 HSPF2, and 12 EER2

You can claim up to 30% of the cost of the job, subject to maximums.

Leaving vents open but closing doors in unused rooms will probably not save money on your energy bill. Closed doors prevent the natural flow of air throughout the home, which could reduce the efficiency of the overall HVAC system. They could also restrict airflow into and through the return vents, making the HVAC system less efficient.

Some types of electric fireplaces use more electricity than others. Models that produce 1,500 watts will have more of an effect on your heating bill than 750-watt models. 

Electric fireplaces use an average of $1.85 of electricity every eight hours. These minimal operational costs aren’t likely to make a big difference in your electric bill—unless you’re using it as a primary heating source for your home and it’s running most of the time.
