During the sweltering summer months, an air conditioning system that is in good repair becomes a necessity for most households that live in a very hot climate. The last thing anyone one on a hot afternoon is to experience problems with the air conditioner. Unfortunately, air conditioners can experience problems and need to be repaired by a certified technician. Some of the most common problems you may experience with your home's air conditioner include:
1. Faulty Thermostat
If your home's air conditioner is not operating properly, the first thing you should check is the thermostat. Many people do not realize that thermostats can wear out after years of use and the sensor can stop working. Thermostats are typically quite affordable in home improvement stores, and the average person can install a new thermostat without the help of a professional.
2. Tripped Breaker
When your air conditioner won't turn on at all, it could be possible that the breaker for the HVAC unit tripped. Circuit breakers are designed to cut off power when the circuit becomes overloaded-- this can happen if the air conditioner's motor or compressor overheats. Check your electrical panel to see if your air conditioner has tripped a breaker. Even if that is the source of the problem, you should still have your air conditioner checked out by an HVAC technician to prevent the same problem from happening in the future.
3. Leaking Refrigerant
The refrigerant inside an air conditioning unit is essential for heat transfer and producing cold air. If your air conditioner is leaking refrigerant, it will not be able to blow cold air through your vents reliably, since the unit will not have the correct amount of refrigerant inside. Refrigerant for HVAC units is very toxic to humans and animals, so if you see liquid around your HVAC unit and suspect a refrigerant leak, contact an air conditioning repair service as quickly as possible.
4. Bad Capacitor
A capacitor is a cylinder-shaped device inside an HVAC unit that stores and transmits power to the fan. When the capacitor goes bad, the fan in the outside unit will not start up, and cold air won't flow into the house. The fan inside the house will blow, but the air coming through the vents will be warm. Bad capacitors are very common during the summer months, but an experienced HVAC technician can replace a faulty capacitor with a new one in a short amount of time.
