Common Reasons Your AC Isn’t Cooling Your Home
When your AC doesn’t supply you with cold air in the summer, it can be a stressful – and hot – time. That’s why it’s recommended to have your air conditioner serviced in the spring before summer rolls around, to ensure everything is in good working condition. However, if you find yourself without cool air this season, there could be many reasons why that is.
1. Incorrect Thermostat
If your thermostat is set incorrectly, you could be thinking your AC isn’t working when that’s not the case. Make sure your thermostat and your air conditioner are both turned on. Then, you’ll want to make sure your thermostat is set about 5 degrees cooler than your currently home’s temperature. At this point, you should be feeling the cool air blowing through the vents. If you don’t, then you may have another issue.
2. Clogged Air Filter
Your air filter should be changed every 1-3 months. If you notice inefficient cooling in your home, check to make sure your air filter isn’t clogged. The debris, dust, dirt and dander can all clog your filter, which will obstruct the airflow and cause your air conditioner to have to work harder to cool your space. The more clogged it becomes, the less air that can pass through so make sure you’re changing it frequently.
3. Dirty Outdoor Unit
Do you have an outdoor unit? Then, you may want to make sure there’s nothing covering it. Leaves and other debris can make your fan work harder. You should always make sure there’s at least 2-3 feet between your outdoor unit and any bushes, branches, or other items that have the potential to obstruct air flow. If you notice your outdoor unit is dirty and in need of a cleaning, schedule a professional cleaning today.
4. Your AC Isn’t the Right Size
Bigger isn’t always better. If you have an air conditioner that is too big, you may find that it shuts off quickly because it doesn’t have to run too long to cool a small space. This can lead to inconsistent temperatures. On the contrary, if your air conditioner is too small, it won’t be able to properly cool the size of your home. Not only that, but you’ll likely be dealing with higher energy bills as a result. To make sure you have the right size AC unit for your space, schedule an appointment with a professional HVAC technician.
5. Refrigerant Leaks
A refrigerant leak can be a serious issue. Not only can it cause your AC to not cool properly, but it can also cause refrigerant poisoning which can be life threatening if not treated right away. If you suspect you may have a refrigerant leak, it’s important you turn off your air conditioner right away and call a professional. Refrigerant doesn’t ever get used up, so if you notice the level has dropped at all then you can be fairly certain you have a leak.
