It’s usually pretty obvious when your air conditioning unit stops working, especially when it happens on a hot summer afternoon. However, you don’t have to wait until you’re covered in sweat to recognize that your system could use some repairs. Below are five warning signs of a failing AC unit to look out for so you can schedule a tuneup before having to change your shirt.
AC Failure Warning Signs
Keep your eye out for any of the following warning signs of an AC failure.
Warm or weak airflow
It sounds like a no-brainer, but it can be easy not to notice that the air coming out of your vents is not cooled. Thankfully, this may be indicative of a simple problem with an easy fix, such as a clogged filter or low levels of refrigerant.
Sometimes the air coming from the vents may be cold, but the flow is very weak. Poor airflow is usually a sign of a leak or a buildup of debris in your filter or vents. Whatever the culprit, you may have a hard time cooling your living space until it’s addressed.
A well-working AC unit should be mostly quiet. If you hear scraping or squealing noises coming from your AC unit, one of its parts may be knocked out of place or in need of lubrication. Even if you can tolerate the noise, the AC unit should still be serviced as an untreated issue could lead to more costly repairs down the road.
A musty smell coming from your AC unit can indicate mold or fungus growth and presents a health hazard to anyone in the home. A burning smell can mean a wiring or insulation problem and pose a fire hazard. It’s also not uncommon for a deceased animal to turn up in a duct. Any odd smells coming from your vents or unit should be inspected by a professional immediately.
If you notice any moisture leaking around your AC system, it should be looked at right away. Refrigerant is a hazardous substance and any exposure can be extremely dangerous. Even if the moisture turns out to just be water, it still indicates a problem with the unit that needs repairing.
One sure sign of a failing AC unit is a sudden increase in your electricity bills with no increase in use. This indicates that your system is now working harder than it should to achieve the same results and is often due to a leak or clog.

Did you know that air conditioning accounts for about 12% of the average home energy bill? And that number could be even higher in Wilmington, NC, thanks to the particularly hot and humid summers.
But there are some ways to keep your electric bill down without the temperature going up. Below are 5 ways to save money on your air conditioning expenses this summer.
5 Steps to Lowering Your A/C Costs
1. Cover your windows
It’s nice to let some natural light into the room, but it also lets the heat in at the same time. Keep your windows covered with curtains or blinds during the hottest part of the day, especially any windows on the sun-side of your house.
2. Plant some trees
Heat creeps into the house through the roof and walls. But planting some tall trees or shrubs near the house can shade the areas where the sun is normally shining. Planting trees may require more of an investment upfront but will pay dividends once those trees are providing enough shade to cool your house naturally and allow you to turn down the air conditioner.
3. Install ceiling fans
The cost to run a ceiling fan at full speed is minimal in comparison to an air conditioner. Moving air helps evaporate sweat from the skin and is cooler than stagnant air. Installing and running numerous ceiling fans throughout the house will allow you to take it easier on the air conditioner.
4. Get a smart thermostat
A lot of money is lost when homeowners run the air conditioner when they aren’t home. Nobody likes coming home to a sweltering house, but keeping the unit running when nobody is there is not exactly efficient.
A smart thermostat can save you a significant amount of money on your air conditioning bill by programming it to only turn on at certain times of the day when you expect to be on your way home, and many can even be controlled remotely with your smartphone.
5. Place your thermostat on the correct wall
A thermostat located on an exterior wall or near a window can register higher temperatures and therefore kick on the air conditioning prematurely or more frequently. Your thermostat should be positioned on an interior wall away from any outside doors or windows. Don’t place it anywhere that receives direct sunlight in order to read the indoor air temperature accurately.
Have Your Air Conditioner Serviced
The above tips are all helpful ways to save on air conditioning this summer. But the single biggest culprit of large air conditioning expenses is an inefficient unit. When an air conditioner is not working properly, it’s forced to work harder. And the harder it has to work, the higher your electric bill ends up being.
A great way to save money on air conditioning every summer is to have your system inspected and tuned up every spring. Our HVAC repair and maintenance includes a 15-point inspection to make sure your system is working efficiently and minimizing your energy output.

How To Prep Your AC Unit for Summer
Clean and check the filters
Once you’ve successfully disconnected the power to the condenser, take a look at the filters. These filters not only act as the first line of defense against indoor pollutants, but they also directly impact the efficiency and longevity of your AC unit.
If a filter appears salvageable, use a vacuum hose to remove as much dust and debris as you can. Then, take the filters to the sink and gently wash them using one part water and one part white vinegar before rinsing with clean water and laying them in the sun to dry.
If there is visible damage to the filter, then it will need to be replaced. This process is fairly simple: Just follow the instructions provided by the manufacturer.
Clean the coils and fan
Most AC units are located outside. Often, these units are covered during the winter, in which case very little maintenance will be required. If not, however, the open grates on the sides of the unit will allow dust and debris to build up on the fan as well as the condenser coils.
Using a soft brush vacuum attachment, gently clean the coils and fan taking special care not to bend anything out of place. If you see any debris at the base of the condenser, be sure to remove it and check that the drain (if applicable) is clear of any obstruction. If there is grime on the blades of the fan, simply wipe them down using a damp cloth.
Inspect the insulation
Coolant lines run from the air handler to the condenser and should be covered with a layer of insulation to combat against extreme temperature changes. Typically a foam coolant line insulation sleeve and insulation tape are used to protect these lines.
Take a look at these lines and replace any insulation that appears damaged or missing as soon as possible to protect the lines from unwanted exposure.
Give the AC a test run
The most important step to ensure your AC unit is ready for summer is to power it up and make sure everything works as expected.
Once the AC unit dries off and the air filters have been replaced, switch the power breaker back on and switch the thermostat to cool to ensure there are no surprises.
