Learn how to tell if your AC is working with these six steps to keep you cool and comfortable
If you find yourself constantly turning down your thermostat, but your house isn’t reflecting a cool temperature, it’s time to examine your AC unit. Fixing your air conditioner can be costly, depending on the problem. However, you may be able to save some money if you can check out what the problem is yourself. Here are six steps to tell if your AC unit is working properly that will help you stay cool in the summer months.
1. Inspect Your Air Filter
Changing your air filter is an inexpensive, easy fix before calling out a specialist, as a filter tends to cost between $50 to $75. To start, locate your air filter, either within the unit or near a vent by your thermostat. Every unit is different, but you should be able to loosen the grill of the vent, pull the old one out, and insert the new one by looking at the arrows on the filter.
Be sure the filter is fully in place by tapping it to ensure it doesn’t move before placing the vent on again. This simple act can help keep your cooling costs down in those hot summer months.
2. Look at Your Circuit Breaker
If your air conditioner isn’t running, confirm you have not blown a fuse or tripped a circuit breaker. High-voltage breakers can shut the unit down. Flip the breaker back, and it should start blowing out cold air again.
3. Monitor Your Thermostat
Sometimes the problem is simpler than you think. Replace the batteries on your thermostat, and that may be the solution to your problem. Periodically check for a blinking battery light or symbol on the thermostat to avoid problems in the long term. If it happens often, it could mean that replacing your thermostat is the best answer.
4. Analyze Your Blower
Head out to your unit to investigate thoroughly but carefully. If your unit is outdoors, you should be able to hear and see if the fan is on. If you can see or hear the fan moving in your unit and you feel air at the top, this means your blower is working, and you can rule it out as the problem with your unit.
If you don’t see the blower moving or hear it working, be sure to mention that when you call a pro.
5. Study Your Drain Line
After you’ve inspected your unit’s blower, look for any signs of leaking. If your coil is covered in ice or you see liquid near the coil, the line is likely leaking refrigerant. You should not try to handle refrigerant and instead call a pro to take it from here.
In the case of a leak, a professional inspection by a local air conditioning repair tech is needed.
6. Consider the Weather
Is your area experiencing a heatwave? When it’s hotter outside, older units have a harder time keeping up. If you’ve checked for everything else, it could just be that your unit is on the older side or isn’t big enough to handle the heat and the size of your home. Because your unit cannot run at its maximum efficiency, it may be time for you to upgrade your unit.
After ruling out all of these issues, calling a local HVAC company can help identify the larger issue. On average, simple tune-up visits cost from $75 to $200, but extended problems can cost you up to $500.
