When summer heat rolls in, your AC system becomes more than just a convenience; it’s how you sleep, work, and stay sane. Basic maintenance helps, but if you’re still struggling with hot spots or constant cycling, it’s time to go a little deeper. At WK Mechanical, Inc. in Middletown, KY, we help homeowners take the guesswork out of AC upkeep so comfort isn’t left to chance.
Our tips below are about getting the most out of your system with real improvements you can feel.
Clean Coils Make a Big Difference
Your AC works hard in the summer, and when the coils get dirty, that job gets even tougher. The evaporator coil inside your house pulls heat out of the air, while the condenser coil outside dumps that heat. If either one gets covered in dirt or grime, it stops doing its job well.
That means your house stays warmer even when the AC runs longer. You might notice it takes longer to cool off, or maybe the air just doesn’t feel as crisp. You can’t always spot a dirty coil unless you open the unit, but a technician can clean it safely using a specialized solution and check for signs of wear.
Don’t Estimate Refrigerant Levels
If your air conditioner feels like it’s blowing room-temperature air, no matter how low you set the thermostat, low refrigerant might be the cause. Your system relies on a very specific amount of refrigerant to cool the air. Too little, and you’ll notice it.
It’s not something you can top off yourself like oil in a car, and it’s not supposed to run low unless there’s a leak somewhere. That’s why checking refrigerant levels is essential during AC tune-ups. A professional uses tools to measure the pressure and determine if your system is functioning properly. If it’s low, they’ll look for leaks and seal them before adding more.
Airflow Problems Can Sneak Up on You
Even if the unit itself seems fine, you might still have rooms that feel warmer than others. That’s often a sign of an airflow issue. Air needs a clear path to travel from the blower through the ducts and into each room. If your vents are blocked by furniture or if a damper inside the duct is closed, airflow drops fast. Sometimes, the ducts themselves get bent or disconnected.
You won’t see that from inside your home, but you’ll feel it. Uneven cooling, weak airflow from some vents, or extra noise can all be clues. If it’s something simple, like a blocked return vent, you can fix that yourself. If the issue is inside the ductwork, however, it helps to have someone take a closer look and make adjustments that get the air moving again.
A Smart Thermostat Doesn’t Fix a Weak System
Installing a smart thermostat might help you manage your cooling schedule better, but it won’t solve bigger problems with the AC unit. If your system is short-cycling, running constantly, or not cooling evenly, a new thermostat won’t fix the root cause. Sometimes the problem has to do with system size.
Maybe the unit was meant for a smaller home, or the ductwork doesn’t match the blower speed. If that’s the case, your AC will struggle every summer no matter how smart the thermostat is. Before spending money on gadgets, it’s worth checking whether your system is even the right size for your house. If you’ve added rooms or finished a basement, your AC might be trying to cool more space than it was built for.
Drain Line Blocks Can Cause Trouble
Summer means more humidity in the air, which means your AC has to pull extra moisture out before cooling things down. That moisture drains through a small pipe that leads away from the system. If that drain line gets clogged with dust or algae, the water can back up and overflow.
Some systems shut off automatically to prevent a leak, while others just keep running and make a mess. You might see water pooling near the unit or notice a musty smell. Clearing the drain line isn’t complicated, but it’s often overlooked. A quick vacuum or rinse with a special solution during your maintenance visit can prevent a lot of headaches.
