(Seasonal Energy Efficiency Ratio)
- Indicates how efficient a heat pump is
- Look for a SEER rating of 14 or higher (Example: If you replace a heat pump from the early 1970’s with a SEER rating of 6 with a new one with a rating of 12, you will cut your heating and cooling costs in half!)
- High SEER ratings increase the “up front” costs a little, but they pay you back many times over
- Ask EMEPA about rebates on 14 SEER (or higher) heat pumps
- Remember the saying “you get what you pay for.”
- The cheapest heat pump may not be the best deal for you
- There are some very worthwhile features that will add cost to certain heat pumps – A few examples:
- System failure sensors that shut down the entire system to prevent damage to expensive components
- Power off timers that prevent a compressor from trying to restart under pressure during momentary power outages
- Dual speed and/or dual capacity compressors which provide more flexibility and efficiency
- Variable speed air handler motors
- Some warranties are longer and more comprehensive
- Discuss these features in detail with your contractor to decide which ones are right for you
- Make sure that your HVAC contractor is performing a load calculation, according to the Air Conditioning Contractors of America
- A Right-J load calculation accurately determines the proper size of a system
- This is not a simple question of “tonnage.” Rather, it is a questions of how much and what type of load.
- Any new system should be chosen from the heat pump manufacturer’s data and based on the Sensible Load and Latent Load characteristics of your home
- EMEPA can provide a free Right-J load calculation for you or your contractor
- Duct work should be designed and sized according to A.C.C.A.
- A Right-D calculation should provide /recommendations
- This assures the proper sizing of HVAC duct thus avoiding airflow problems
- Use flex duct ONLY in areas where rigid duct cannot be installed
- Any duct not located in the interior air space should be fully insulated
- Incorrect placement of supply registers can make the difference between a comfortable system and an uncomfortable one
- ALL DUCT JOINT AND SEAMS SHOULD BE SEALED WITH MASTIC!
- No longer is duct tape sufficient for seams, because duct tape will loose its adhesiveness with time
- EMEPA can provide a free Right-D duct plan for you or your contractor
