yea that sounds good
Your system is new enough to not worry about then. Do you know what SEER it is?
If your inside ambient air is 77* then yours is working ok, for a 117* day. By those numbers I would guess you have a single speed unith that is about 10 opr 12 SEER. That is what most a/c units are. The higher the SEER rating and the varibale speed units are what you are looking for.
The key being variable speed. What that is basically is just what it sounds like. There are two compressors in the outside units. One runs most all the time and the other one (the largeone) kicks in and cools down when the smaller ones "needs help" You would think that with it running all the time that your electric bill would be higher but it is actually less.
Think about this for a second. Most standard units run for a while then shut off (right). Then as the inside air heats back up the unit comes back on and cools down the house, right....... WRONG
Here is why. When your a/c is running before it came get cold air inside your house in has to cool down the air duct lines that are more than likely in your 145 165* attic. The attic air will heat up the air inside your ducts and when the units come on you the coold air will push all that super heated air into your home. Now the vents for the most part are put on your cielings so you will never know this. But stand in front of a grill and feel the hot aor that comes out when the unit comes on. Ron , you can point your thermomitor (sp) at the grill and see first hand the difference.
Then when your unit shout off it leaves all that cold ait you paid for in the attice ducts to get superheated again. It is a vicious cycle.
Now on varible speed units the smaller unit runs all the time, for the most part. Keeping the cold air you paid for coming into your house where it is needed. When the air gets warmer the larger compressor kicks in and cools it back down. This cycle will run for a lot less time that your standard single speed units run so, you are saving money by keep the hot air out of your ducts in the first place.
This is the short version of what all takes place. It would take me all day to ttpe what actually happens. But it does work and it is very cost effective. A variable speed unit will add about $850.00-$900.00 to the cost of a five ton unit. Most a/c units are three to threee and a half ton units.
As for the sprinkler. If you have an automatic sprinkler just point a head at the unit. it does not take much water at all.
