HVAC system is critical for productivity, safety, and comfort. One of the most frustrating experiences is when it fails to start during O’Fallon’s sweltering, muggy summer weather. Before you call an HVAC technician, try resetting your air conditioner. If there was a power outage or the breaker was tripped, a quick reset can solve the issue. There are many reasons the AC may not work, such as faulty equipment. However, sometimes you can solve the problem with a restart. In this article, we will outline how to reset your system and why it may be essential.
Why Do I Need to Reset My HVAC ?
The most common reason for an AC unit requiring a reset is when the protection circuit breaker in your AC unit kicks in. This typically happens after a power outage and is in place to prevent fires and explosions.
A reset can also correct an AC that’s only blowing warm air, even when the thermostat is set to “cool.” There are a handful of reasons your AC could be blowing warm air, but one of them is a general thermostat error. Sometimes a hard reset of your AC can solve that problem.
While resetting an air conditioner is an easy task, if you are uncertain or uncomfortable, please contact an HVAC professional to assist by requesting an appointment with One Hour Heating & Air Conditioning. As a final precautionary note, accessing your resent button may require you to open your condensing unit plan and with certain units, this could impact your warranty. Please check your warranty guidelines before attempting to reset your air conditioner. If you are familiar with your AC unit, and comfortable moving forward, follow the simple instructions below.
How to Reset an HVAC
Reset Your Circuit Breaker
If you can’t reset your air conditioning unit through the isolation or reset buttons, you can try the circuit breaker. The breaker is usually in your laundry, the side of the house, or the basement. In some homes, it will be in a closet or even the crawlspaces.
The breaker box typically has one big switch and multiple switches for separate circuits in your home. Most breakers will have a label indicating the specific connection. Locate the one labeled “AC” and switch it off.
An outage or electrical surge can cause the breaker to switch off. If there is no label, find the switch in the neutral position and turn it on. You can now restart your AC to test if it is working.
