HomeEnalasys™ Energy Efficiency: Heating & Cooling

Your air conditioner and/or heater contributes to the greatest amount of energy consumption and ultimately you end up paying for it. Enalasys is working with utilities to create unique programs that offer residential home owners and non-residential commercial businesses special rebates for updating and improving the efficiency of your home energy unit. Getting your system into shape can improve your home or business comfort, air quality and reduce your monthly energy cost.

The average price of electricity is 9.5 cents per kilo-watt hour. The average price of natural gas is $12.42 per million Btu.

Quick Energy Facts:

  • Heating and Cooling account for up to 50% of your Home Energy Bill
  • Switching to a more efficient air conditioner or heating unit can save you anywhere between 7 and 23 percent of your monthly energy bill depending on the size and efficiency of the unit you choose.
  • Investing in a more efficient air conditioner or heater will save you more in the long term.
  • About one-seventh of all the electricity generated in the US is used to air condition buildings.*

Do any of these statements apply to you?

  • My utility bills are excessive, especially during summer months
  • My Air Conditioning System cools slowly and unevenly
  • I do not regularly maintain my A/C system
  • My home is dusty
  • Our heater is noisy

If you answered yes to one of the above statements, your home air conditioner or heater may need to be tested by a participating HomeEnalasys™ contractor. HomeEnalasys™ contractors use advanced equipment that provide PROOF of SERVICE, unmatched by other contractors in the field.

A properly functioning Air Conditioning System:

  • Creates Comfortable Home Air Quality
  • Results in Energy Savings
  • Will Last Longer with Fewer Repairs
  • Is Easier on the Environment and the Planet

Have you had a HomeEnalasys™ energy evaluation? Enalasys has created breakthrough technology that will accurately identify inefficiencies in your home heating and cooling systems.

The HomeEnalasys energy evaluation program was developed by Enalasys to ensure quality installation and maintenance on new or existing air conditioning and/or heating systems and ductwork. HomeEnalasys™ participating contractors use our patented technology to diagnose your home air conditioning or heating systems for duct leakage, proper airflow, temperature and refrigerant levels.

Enalasys is working with utilities to create unique programs that offer residential home owners special rebates for updating and improving the efficiency of your home energy unit. Getting your system into shape can improve your home comfort, air quality and reduce your monthly energy cost.

Common Terms

What is HVAC?
HVAC stands for Heating Ventilation and Air Conditioning.

What is SEER? Seasonal Energy Efficiency Ratio
A higher SEER number is better. The SEER will be listed prominently on the yellow-and-black Energy Guide. The SEER is defined as the total cooling output in British thermal units or BTU provided by the unit during its normal annual usage period divided by its total energy input (in watt-hours during the same period).

What is EER?
EER stands for Energy Efficiency Ratio. It's the simple output of the equipment divided by the input. Again, a higher EER number is better. EER will also be listed prominently on the yellow-and-black Energy Guide and is an efficiency rating known as the energy efficiency ratio.

What is HSPF?
Heat pumps have a rating indicated known as Heating Seasonal Performance Factor or HSPF and a higher number is better. HSPF is a measure of a heat pump's energy efficiency over one heating season. It represents the total heating output of a heat pump (including supplementary electric heat) during the normal heating season (in Btu) as compared to the total electricity consumed (in watt-hours) during the same period.

Replacing Old Equipment: Why it is important?
A central A/C system is designed to last 12-18 years, so in some cases savings and reliability are limited due to equipment age. Your A/C contractor can help you decide when it is time to replace your old equipment with high efficiency equipment before your system breaks down and leaves you in the heat.

Duct Testing: Why Is It Important?
The ducts that are part of central heating and cooling systems offer one of the best opportunities to increase your energy efficiency, increase your comfort, and manage your energy bills. Studies indicate that 28%-35% of the heated or cooled air is lost-along with the money spent to heat or cool that air-through leaky ducts. Properly sized, installed, and sealed ductwork will make your heating and cooling systems significantly more efficient.

Refrigerant Charge and Airflow: Why is it important?
A system refrigerant check-up is a recommended service that should be performed when the equipment is first installed and during annual system check-ups. A refrigerant charge should be conducted if the system check indicates that one is needed. Once the system has been properly charged with refrigerant and has good airflow across the indoor coil, and assuming there is no damage to the duct system, only basic service such as changing filters and cleaning the outdoor unit annually should be needed to maintain the system operation at peak performance levels.
