When a homeowner turns on the air conditioning in their home, they do so to cool the space. However, sometimes, the level of cooling they experience is far more than they requested. When an air conditioning unit is too cold, it is not normal and is usually an indication that something is wrong.
1. Vent Obstructions
A vent obstruction might be to blame if certain parts of your home appear cooler than others. When a vent is obstructed, air cannot pass through. As such, the air reroutes and is forced out of another vent, pouring too much cold air into one space. The ducts should be inspected to see what is causing the obstruction.
2. Clogged Air Filter
Air filters should be changed at least four times a year, and maybe more for people with pets. When a filter is clogged with debris, the air conditioning has to work harder to push air through the filter. When the unit works harder, it will also produce more cold air. However, with this issue, a cooler-than-desired home is only one problem; you risk shortening the unit's lifespan due to excessive working.
3. Incorrect-Sized Unit
If your unit is brand new or seems in otherwise great shape, you could feel too cold in your home due to being too large. How much cool air an air conditioning unit produces is based on size, so if it is sized for a larger home than yours, you will end up with too much cold air inside. This issue can also lead to increase energy usage costs.
4. Dirty Contactor
When the preset temperature on the thermostat is reached, the contactor inside the air conditioning gets a signal, which in turn causes the unit to power off. Sometimes, dirt and insects can collect on the contactor. If it is dirty, it will not receive the signal, which will cause the air conditioning to continue to pump cold air into your home.
5. Faulty Thermostat
The thermostat sends the signal to the contactor that the proper temperature has been reached, but sometimes, the thermostat may not measure the temperature accurately. When a thermostat is faulty, it can register a temperature warmer than it is, forcing the unit to remain on. It may be time for new batteries or a complete replacement.
If your air conditioning is freezing you out, get out of the cold. Contact an HVAC professional to inspect your unit so that the appropriate repairs can be performed.
