If you want your air conditioner repaired, even at the end of the warm season: it’s always wise to fix anything before it has a chance to create more damage and raise expenses. There have been some really hot days in Thornton, Colorado if your AC can't keep up, don't turn the thermostat down. It may be the first think of, but you could cause your air conditioner to breakdown.
However, when homes start to grow hotter than normal while the air conditioning system is running, people often resort to a simple “solution”: they turn down the thermostat further. The recommended temperature setting during the summer is 78°F (this comes from the Department of Energy). If you’re used to having the thermostat at this temperature, but your house begins to feel hotter, you’ll feel the temptation to lower the thermostat setting to make up for it.
This is a mistake! There’s something wrong with the HVAC system somewhere, and lowering the thermostat will not solve the problem. It will probably make it worse!
If Your AC Can't Keep Up, Don't Turn the Thermostat Down
A note on thermostat operation
First, we want to clarify how a thermostat works to show that lowering it isn’t a way to get more
cooling. The thermostat doesn’t operate like the throttle in a car. You aren’t pushing down a pedal that makes the air conditioner “ramp up” and produce greater levels of cooling. A thermostat is actually a switch; a switch often connected to complex computer controls, but still a switch that’s “on” or “off.” When the indoor temperature registers as higher than the setting on the thermostat, the thermostat turns on the compressor to start cooling the space. When space is cooled down to the setting, the thermostat then turns off the compressor.
So when you turn down the thermostat to a low setting, you’re just requesting that the compressor run longer
to reach that temperature. It isn’t a way to make the AC work faster at its job or give you better cooling levels.
An AC that can’t keep up needs to be repaired
You can see that even under normal circumstances it’s not a good idea to turn a thermostat down too low: the compressor will run longer without giving you better cooling. Trying to use this to compensate for an air conditioner that can no longer cool down the house the way it should is putting extra strain on a system that’s already malfunctioning. You may end up hastening a complete AC failure. After making checks on the air filter to see that it’s clean and that all the vents are unblocked, call on HVAC professionals to see what’s wrong.
Sometimes the problem is actually in the thermostat. If the temperature sensors are miscalibrated, the thermostat may be shutting the compressor off prematurely—and that means you won’t get the cooling you need. There are many other possibilities, however, including issues with the compressor, the evaporator coil, the blower fan, or even the ductwork. It takes an HVAC expert to complete a proper diagnosis, and we have the right people for the job!
Schedule Professional Maintenance
Like a car, a central air conditioner is a big investment. Just as you take your car into the shop for a tune-up, you should have an HVAC contractor look at the unit every year. When a professional services your air conditioner, they will make sure the various parts have sufficient lubrication and will make adjustments that will help increase the efficiency of your system. They will also let you know about minor problems that need attention before they become expensive repairs in the future.
