Let me start by saying:
WHETHER YOUR HOME IS NEW OR OLD….YOUR HEATING AND AIR SYSTEM IS VERY INEFFICIENT.
I have yet to find 1 home out of hundreds that I have tested over the years to actually meet its rated efficiency!!
The above is a 100% provable statement – Pick a home (any home) and I’ll show you that its Heating and A/C system(s) are underperforming by at least 40%. The majority of them this number will be much worst.
You might ask WHY?…
It has to do with 3 main factors that have to be done properly that I have yet to see get done right.
These are:
1) System Sizing ( AKA : “Load Calculation” ).
2) Distribution (“duct”) System.
3) Refrigerant System.
The reason these things are not done or not done right is due to alot of “rules of thumb” type practices as well as a lack of testing & understanding of whole house system performance.
THE KEY IS:
ALWAYS TEST – NEVER GUESS!!
