Is over sizing your air conditioner better? D C’s heating & air conditioning 949-770-9616 Ok I have read many different posts on over sizing your air conditioner is bad! I want to ask why do you feel this way? I took out my 3 ton air conditioners system in Laguna Hills California and replaced it with a 5 ton 16 seer high energy efficient air conditioning system.
Is over sizing your air conditioner better?
Here are some of my results and down falls!
My electric bill went from $500.00 plus a moth down to $200.00 because the air conditioner unit does not have to run all day to cool down my home now! Yes run time is the key factor for high electrical costs! I do understand that living in southern California has less humidity than most states and we do want the air conditioner to remove the latent heat or humidity in the home or business!
Sizing Your HVAC System For Home Or Business
Ok we know or I am going to tell you that for each ton of refrigeration we need 400 cfm of airflow across the coil. Before having the 3 ton air conditioner I was only pushing 1200 cfm across the coil removing both the sensible and latent heat of the air to condition my home this result was with a 20 degree differential inside air against supply air coming out of the register.
Now that I over sized my unit to a 5 ton air conditioner the amount of air across the coil is now 2000 cfm more air to be conditioned both latent and sensible! With still a 20 degree differential the unit does not have to run long and thus saving money because the air conditioner is not running as long and all day!
HVAC Removing Heat From Your Home And Business
Here was the down falls that needed to be corrected! I was getting to much airflow through the supply registers! This is a easy fix if this happens to you just re duct with larger ducting to keep the velocity of the air lower and more flow! Velocity is the speed, which air flows and can be adjusted with dampers or the ducting. I also changed my supply registers to a newer style that allows me to change the flow directions also another cheap fix.
Removing the heat energy or cooling it removes humidity from the air! Either a large size air conditioner or smaller one will remove the moisture! I do not understand why people would not want a bigger air conditioner for those extra hot days?
Ok maybe you might say to my comment it costs a little more to run because the air conditioner is bigger now! True it will cost a fraction more but will not run as long as my old one did all day!
Like the old saying go big or go home! HAHA I did go big and I am impressed on how great my air conditioner works and the great savings on my electric bill!
