Nothing beats air conditioning on a hot day, as it drastically improves indoor comfort. However, your system may malfunction, rendering it inoperable. In such a case, you may notice the cooling unit failing to turn on, creating an uncomfortable atmosphere. When this happens, you may want to call an AC repair expert to come and check your unit as soon as possible. On arrival, they will inspect your system and remedy the underlying malfunction to restore proper cooling. The following are the reasons your AC is not turning on.
Tripped Circuit Breaker
During inclement weather, your system may experience power surges, creating a current overload that trips the circuit breaker. Additionally, worn-out electrical components such as naked wires may cause a short circuit, triggering the circuit breaker. As a result, the breaker will cut power to your AC, preventing it from running. This means your unit will not turn on when you instruct it until you reset the circuit breaker. Note that electrical failure is a problem only an expert should handle to avoid electrocution or the risk of fire damage. In this case, the AC expert will replace the worn-out wires for proper current flow. In addition, they will install a surge protector to prevent voltage spikes in your home.
Clogged Condensate Line
Your AC cools as it simultaneously dehumidifies the air in your home. In this case, the evaporator coil facilitates heat exchange between the coolant and air. Note that as the air cools, water will drip and collects on the drain pan. However, if there is dirt and grime build-up on the condensate line, it will restrict water from flowing out. This results in a water backup that overflows in the drain pan and triggers the float switch. Ultimately, the system will not turn on as the float switch aims to prevent water damage.
Clogged Air Filters
An air filter traps dust, dirt, and other airborne particulates, ensuring clean air circulation. However, contaminants may accumulate on the filter, hindering airflow. This causes the evaporator coil to ice up as the refrigerant flows without adequate air for cooling. Since the internal pressure is too low, your compressor may overwork to pressurize it, causing it to overheat. As a result, your unit will not turn on until the ice on the evaporator coil thaws.
Defective Thermostat
A thermostat will display the room temperature and allow you to adjust it to your preferred level. However, dirt and dust accumulation on the thermostat may restrict proper temperature detection. On the other hand, placing your thermostat near heat-emitting sources may cause it to detect temperatures inaccurately. Consequently, the device will not send signals to your system to run cooling cycles, hence not turning on.
A unit that will not turn on can be a major inconvenience in your home. Thus, you should employ the services of an AC expert for maintenance checks to ensure your unit offers peak performance at all times.

Every summer, I agonized over energy bills that would shoot into the stratosphere as a result of my efforts to keep cool in the heat. Every time I turned the temperature down, my bills increased. This summer, I decided to take some of the control over my energy bill back. I installed reflective film on my windows that reduced the amount of light and heat coming into the house. I started serving more cold meals or asking my husband to barbecue outside, so that my air conditioner didn't have to compete with the hot stove, and I started doing laundry at night to reduce appliance heat in the house at peak times. I also had ceiling fans installed. So far, the difference in my bill has been tremendous. This blog is a way for me to explore other ways to reduce energy drain during the summer months.
