Summer is coming soon and checking/tuning the air conditioning system is a Must.
Some you can do yourself;
1- Air filter checking
2- Cleaning around the outside unit, all those unwanted grass growing next to the unit need to be cut.
3- Black plastic pipe covering the copper line should be good.
4- Small thermostat wire at the unit outside should not be dry to break.
5- in your attic look at all ducts to see if any of them broken and loosing air. When your ac is running your attic temp should not be cooler than outside, if it is then there is an air leak.
6- there is a tray under the unit in the attic, that tray should be dry. If it is wet , it needs to be checked by an air conditioning person.
7- turn your ac on and let it run for 1/2 hours , then check the air temp coming out of the vent verses air temp going in to the air filter.
The different should be between 15 and 20 or higher. If it is not, it needs to be checked by an ac person.
I hope this would help any one who needs it and beware of inexperienced person to tell you other ways .
