5 Reasons Why Your A/C Won’t Turn On

We can all agree that the temperature is brutally hot during the summer. But do you want to know what’s more frustrating? It’s when your central air conditioner suddenly stops working. Here are five reasons why your A/C won’t turn on.

Refrigerant Leak

If the air coming out of the vents isn’t cold, then there could be a leak in the refrigerant lines. Small puncture holes allow the refrigerant to escape—causing low refrigerant levels.

There are a few things that cause refrigerant leaks, such as:

  • Corrosion of copper tube walls of the indoor coil
  • Improper AC installation
  • Vibration
  • Factory defects in your unit
  • Normal wear and tear causing thinning of tube walls
  • Joints or connections weakening over time

When faced with this problem, you’ll need to drain the refrigerant lines, repair the hole, and then recharge it with the correct level of refrigerant.

If you need assistance with fixing the refrigerant leak, then we advise you to call your trusted HVAC experts.

Broken A/C Motor

Your air conditioner goes through a lot of wear and tear during the summertime. If you don’t feel any air coming out of the vents, then the fan motor might be failing to push the cold air through the ductwork.

We do not recommend fixing it by yourself. Contact a professional technician to deal with the problem for guaranteed results.

Dirty Air Filter

Are you replacing your filters only when it’s needed? While the rule of thumb is to change your air filter every three months, it’s best to check its condition to see if it’s tremendously clogged and needs replacement. When it’s incredibly full of dust, bacteria, or dirt, it won’t effectively intake the air that it needs to cool.

Not sure about the kind of air filter you need? We recommend that you hire an HVAC professional in Manassas, VA, for expert assessment and advice. We will change your filters so that you’ll feel nice and cool in your home again.

Thermostat Issues


Thermostat issues may look simple, but they are among the common reasons why your A/C won’t work. Here’s a checklist for your thermostat before spending cash on costly air conditioning repairs:

  • Are the batteries drained?
  • Has the thermostat been bumped? Or is it properly fixed?
  • Is it set to “cool” mode?

It’s always good to check things before spending unnecessary money, especially if it doesn’t need a replacement. However, if you see the need to swap it out with a new one, then you can give a call to your reliable HVAC company in Manassas, VA.

Clogged Condensate Drain Line

Your air conditioner doesn’t only lower the temperature in your home; it also pulls the air’s humidity. The moisture is drained through a condensate drain line and takes that moisture back outside. Alternatively, if this line gets congested with gunk, then the water will be collected inside your A/C drain pan. It can stop your air conditioner from blowing cold air or even shut it down.
