7 Reasons Your Air Conditioner Is Not Starting and How To Fix It…

Whenever you run into any problem with your air conditioning unit, it can be frustrating. Not being able to turn it on at all, will make you feel hot and helpless. The following are some reasons why your AC will not turn on… 

3 Easy Fixes You May Be Able To Do On Your Own

  • Thermostat Is Not Set Right – This is by far the simplest fix so before you lose your cool, double check your thermostat. Set your temperature lower than what it is outside, make sure it is set to “cool,” and that your system is responds to changes as you make them. This may seem silly to mention but surprisingly, it is not uncommon to overlook. 
  • Air Filter Needs Cleaned or Changed – Dirty air filters reduce the flow of air in your HVAC system and throughout your air ducts. Without a steady flow of air, your system might overheat and shut off then refuse to start back up. It may also cause your AC unit to freeze. This occurs when frost and ice form inside the unit and keep your unit from operating.
  • Your Unit Tripped It’s Breaker – Your HVAC unit likely has its own circuit on your service panel. Go to your breaker box and see if the breaker was tripped. Reset it. If this is a reoccurring problem; you should contact an electrician or HVAC repair company.

When You Should Call A Professional HVAC Repair Company

  • Dirty and/or Frozen Coils – Dust often find itself on evaporator coils which may result in caked on residue that will restrict air flow and limit the abilities of the unit. One reason AC tune ups are necessary.
  • Clogged Condensate Line – In time, the drain pan and condensate line may clog. These parts remove moisture from the unit. If they become clogged, the system might become backed up and refuse to start as a means to self-preserve.
  • Refrigerant Leak – Air conditioners will still run despite a refrigerant leak but because the unit does not have what it needs to remove heat, it will freeze up.
  • An Internal Component is Damaged – Worst case scenario, your internal component has become damaged keeping your AC unit from starting up. If you noticed any unusual noises prior to it not working, your AC blower assembly might be damaged; your condenser could be failing, or there could be another problem with one of the components.
