Upgrade your HVAC system to one with a SEER rating of at least 14. If your ac unit is more than 12 years old, consider replacing it with a more efficient system. Install a programmable thermostat to automatically adjust your home’s temperature settings when you’re away or sleeping. When used properly, a programmable thermostat with it’s 4 temperature settings can save up to $100 a year in energy costs. Seasonal Energy Efficiency Ratio. A measure of cooling efficiency for air conditioners. The higher the SEER, the more energy efficient the unit.

  R-410A is the common name for an emerging hydro-fluorocarbon (HFC) that is being used as a refrigerant in the HVAC industry. R-410A is more environmentally friendly than R-22 and is being seen as the most likely replacement for R-22 by HVAC manufacturers. At the beginning of 2010, the use of alternate refrigerant will be required in HVAC manufacturing.

At CHAPA’S A/C we realize that purchasing a heating or air conditioning system is no small matter. However, if your existing system is old, in need of repair or simply inefficient, purchasing a new unit, one which can be as much as 60% more efficient than a system purchased just 10 years ago, can offer long-term benefits. Rather than continuing to pay for ongoing maintenance and costly monthly bills, invest in a new system today that will save you money for years to come. Replacing a unit that is 10- to 15-years-old may reduce electricity costs by 30 to 50%

Variable speed units run longer, at lower speeds, allowing air to constantly circulate against the cooling coil and remove more moisture. Variable-speed motors also use less electricity than regular motors, reducing your energy costs
