Why Isn’t My Air Conditioner Working Right?

Temperatures may still be mild for now, but you know how quickly summer can creep up on us, and before you know it you’ll be turning on your air conditioner. With proper maintenance, you shouldn’t run into any detrimental problems this summer. But not every AC issue is 100% avoidable, and one of the most common service calls that HVAC technicians get are in regards to a customers’ air conditioner not working right, as in it is turning on but not cooling their home. If this is you, don’t worry just yet. Read below for some common reasons your air conditioner might not be working as you expect.


Simply put, someone else in your home might have messed with your thermostat. While this may seem too obvious, you should double check. Remember that your family members might actually have different cooling preferences than you do, so be sure that your thermostat hasn’t been set to another temperature. You should also look to see that it’s displaying correctly and that it is set to “on.” You could just have the fan running without the thermostat being set to “cool.”

Damaged Ductwork

Your ducts are essential to a functioning central air conditioning system. If ductwork becomes cracked or bent, your conditioned air may be escaping through the ductwork. This could even happen if your ductwork was designed or installed poorly to begin with. While you will need a professional to inspect and possibly repair this, it’s not a huge problem.

Condenser Obstruction

Your condenser unit is located outside, and as such can get blocked by plants, bushes, other shrubbery, trash, or even mulch. If it’s blocked, it won’t receive enough air to release heat from the condenser coils. A dirty or blocked condenser unit can also cause your air conditioning unit to shut on and off repeatedly, a process known as short-cycling.
