5 Signs Your Air Conditioner is Failing 

By Angell Aire /

In the summer months, air conditioning is a necessity rather than a luxury. Without air conditioning, your home may feel sticky and humid, with interior temperatures spiking to dangerous levels during a heat wave. So you can stay safe year round, learn 5 signs your air conditioner is failing so you can schedule a repair before the unit breaks.


You hear odd noises

Strange noises indicate there’s something wrong. If your air conditioner sounds louder than usual, or if it makes a strange hum, it’s wise to get the unit inspected. Some noises can be fixed with routine maintenance, while other noises indicate the unit is on its last legs and should be replaced. Being proactive about air conditioner maintenance means you can get the unit repaired or replaced before it breaks down, so you don’t need to suffer without air conditioning.


Your home doesn’t feel cool anymore  

You run your air conditioner like usual, but your home feels warm: This tends to mean your thermostat is broken or your air conditioner needs a fix. Troubleshoot both problems with a call to your local HVAC technician, who can inspect the air conditioning unit and the thermostat, to make repairs.


There’s low airflow

If you put your hand up to the vents and feel nothing or a very low airflow, then there may be a problem with your ducts or the blower fan. Dust can clog air conditioning ducts over time, making it difficult for air to flow through the system. Your HVAC technician can inspect the system, clean the unit, repair the fan, and make sure everything works the way it should This can have the side effect of improving indoor air quality, by removing dust in the system.


Your AC cycles on and off repeatedly 

When things are working properly, your air conditioner should stay on until the home is cool to the desired temperature, then turn off. When your air conditioner cycles on and off repeatedly, it indicates something isn’t right. A simple fix may be a good cleaning or a new thermostat, but you could be looking at replacing the condenser. Depending on the age and condition of your unit, it could be better to replace an old air conditioner than spend money fixing it.


Your utility bills have spiked

It’s common to spend more on energy during the summer because your air conditioner is working so hard to cool the home. However, if you notice bills have gone up, and temperatures don’t seem unusually high, it could be a sign your air conditioner is nearing the end of its life. If you’re not sure why the bills are higher than they should be, it’s worth the peace of mind to have an HVAC tech out to inspect things.


If you notice one or more of these signs, schedule an appointment for air conditioner cleaning and repair. If you delay the phone call because your unit still functions, you risk waiting so long that you can’t get an appointment when you need it due to peak demand. Rather than suffer through a heat wave with an underperforming or broken air conditioner, get your unit checked out today and gain peace of mind with preventative AC maintenance.



"Jason was very professional and knowledgeable. He gave a summary of everything he did and how our furnace and AC are performing based on their age. Fortunately, we had a good check up and he didn't try to sell us any replacement parts that we didn't need. Highly recommend!"
