Signs That Your Central Air Conditioner Is Struggling


The central air conditioner you have installed in your home is one of your household’s most prized resources, even if you don’t think of it as such. Consider how much it does for your quality of life!

Central air conditioners are also one of the most specialized home comfort systems that can be found in a household–while the average homeowner can typically handle small tasks like fixing a leaky faucet, replacing an outlet plate, or changing their air filter, anything that involves adjusting or repairing the components of an air conditioner must be done by a trained and experienced professional.

Just like your vehicle or any other big piece of equipment, your AC system needs routine professional maintenance to keep it working as it should, and it’s a lot easier, and more affordable, to address a problem when it’s just begun rather than when it’s had time to build up and create further problems within the system. But how do you know when your air conditioner needs repair service? Read on to find out!

Lack of Cool Air

This problem is pretty apparent, right? After all, your air conditioning system is supposed to keep your home at an even, comfortable temperature. Poor cooling ability may mean something as simple as a gradual refrigerant leak (this is still serious and needs professional assistance to fix) or an air filter change (which you can do on your own).

Alternatively, however, it may be something more serious, like a failing compressor or ice development on the evaporator coil preventing the system from doing its job to absorb heat. Regardless, it’s time to call in a professional if you notice poor cooling performance.

Poor Airflow

Have you noticed that rather suddenly, what used to be a nice, powerful blast of cold air through your vents has become weak and puny? There could be a couple of issues at hand here–your HVAC system’s blower might be starting to fail, or there could be an issue with the ductwork in your home. If some rooms in your living space are getting better airflow than others, it may very well be a problem with damaged ductwork.

What can happen is that debris such as dust and mold spores can accumulate in the cool, damp passages of your air ducts, and this is more than simply an air conditioning performance issue–it can be a health hazard for you and your family and should be addressed ASAP.

Thermostat Troubles

Your thermostat is essentially the brain of your central air conditioner, helping to control and regulate your air conditioner’s temperature settings. If your thermostat is failing or miscalibrated, you might notice symptoms like your air conditioner not turning on, or not shutting off, or a temperature reading that doesn’t seem to correspond with what the actual temperature is inside.

Whatever the case, while you’ll first want to check that you have the right setting, your next step should be to give us a call.
