Unit Efficiency


"Every unit that is already installed or is about to be installed have all been engineered to operate within certain parameters. When any of the units are operating outside of those parameters, there is most likely going to be a unnecessary and inefficient work load placed on both units (indoor/outdoor unit). The words both units is used because if one unit is operating out of spec. then the other ultimately is affected as well. 

Therefore the overall efficiency of your units reflects greatly upon your homes utility bills as well as the life span of your units."





Heating and cooling costs account for nearly half the home's total energy bill.


ENERGY STAR certified central air conditioners have a higher seasonal energy efficiency ratio (SEER) than standard models, which makes them about 14% more efficient than standard models. The higher the SEER, the greater the efficiency. Since sizing and proper installation of a central air conditioning system are critical to energy efficiency and home comfort, it is important to hire a qualified technician.


Although these products can be more expensive to purchase up front, the cost difference will be paid back over time through lower energy bills. 


Proper maintenance can go a long way in preventing future heating and cooling system problems. Ask your contractor about annual pre-season check-ups. Contractors often get very busy during summer and winter months, so it's a good idea to check the cooling system in the spring and the heating system in the fall.


How can I be more efficient?


  • Replace outdated equipment.  In 2006, the federal government increased the minimum cooling efficiency standard for new air conditioning units.  This rating is commonly referred to as a SEER (Seasonal Energy Efficiency Ratio) and all new air conditioning units manufactured after 2014 must be rated a 14 SEER or higher.  To be considered energy efficient, a unit must rate 14 or higher so In contrast, units manufactured prior to 2006 were only required to have a rating of 10 SEER.  That means that replacing even a 10 year old system could save up to 30% in energy costs.


  • Ensure equipment is properly installed.  


  • Properly sized ducts that are well insulated and sealed for minimum air leakage are also important to maximize efficiency.


  • Taking steps to reduce building load before replacing or upgrading is crucial to not only make sure that existing systems run less frequently but to also allow for smaller new systems, which lowers operating costs.  There are many simple ways to reduce load, all of which allow less heat to enter occupied space: Improving insulation and building envelope allow for less leakage. 

  •  Programmable thermostats, multiple heating and cooling zones and demand CO2 sensors are all strategies to ensure that systems are only being used when necessary.


  • Perform ongoing Maintenance.  Regular maintenance improves the efficiency and increases the useful life of heating and cooling systems
