FYI. For homeowners.

We get calls from our customers and they have various questions about how an A/C unit works.

1. If a proper load calculation is performed on your home, and the unit is sized based on ACCA manual J's processes, then the temperature of the inside will never be able to be colder than 20 degrees minus the outside temperature.

For example. If it is 95 degrees outside, then the coolest you could expect your home to get is 75 degrees. If it is 100 degrees, then 80 is the lowest.

2. A common question we get is... Does it hurt my system for it to run long periods.
And the answer to that is NO. Leave your thermostat set on whatever temperature you wish and let it run. On a VERY hot day you could expect your unit to run ALL day. And those motors never need a break. In fact, the starting and stopping of a motor is more dangerous than running continuously.

3. If I set my thermostat to 70, does my unit cool faster because it is lower? NO. The typical air conditioner, unless it is a TWO-STAGE unit, doesn't cool more at a higher capacity if it is lower. A thermostat is merely a switch to bring on your unit. Whether it is cooling or not is determined by whether the unit is operating properly. And even then, proper maintenance can extend the life of your system and it's functionality.

Gibson's All American HVAC specializes in keeping older units running longer. You can sign up for one of our maintenance programs that ensures you system is operating at it's optimum level.
