Depending on where you live, summer temperatures could climb well above 90 degrees. As a result, you probably rely on your AC system to ensure that your home stays comfortable all summer long. However, if your air conditioner isn’t cooling your home, there it can be a real source of frustration and create some pretty uncomfortable conditions inside your home.
If you’ve discovered your AC not cooling, there are a few things you can do before you call a professional. From checking your air filters to ensuring your thermostat is working, the problem could be a simple fix. Keep reading for some tips on what to do if your air conditioner isn’t cooling your home.
Clean or replace the air filters.
Most people don’t think about their air filters until they start having problems with their HVAC system. Contrary to popular belief, air filters are not just there to keep your system clean; they also play a very important role in your comfort. When air filters are clean, they provide clean, fresh air for your home and improved indoor air quality. However, when they’re dirty, your comfort could be in jeopardy. In fact, a dirty air filter can lead to reduced airflow, frozen evaporator coils, and system failure.
This is because a dirty air filter can impede airflow and prevent the coils from maintaining the right temperature. Dirty air filters lead to a number of problems, including a decrease in comfort and an increase in your energy bills. Most experts recommend cleaning or changing your air filters every three months. However, if you have pets or if you smoke, you may need to change them more frequently. This is especially true during the summer when your AC is running more often.
Check for ice on the coils.
If your AC unit isn’t cooling, you should check to make sure there is no ice on the coils. If there is, you will need to thaw them out before the unit will start working properly. You can do this by using a hairdryer or by turning on the furnace and letting the heat blow through the vents for a few minutes. There are a few reasons why your evaporator coil would freeze over, including obstructed airflow and dirty coils. If you can’t find a reason why your coils are freezing up, you might need to contact an HVAC technician to diagnose and remedy the problem.
Check your thermostat.
As the director of your heating and cooling operations, your thermostat plays an important role in maintaining temperatures in your home. If your AC isn’t cooling, you can check your thermostat settings. Your thermostat has two modes: cool and heat. The cool mode is used to lower the temperature in your home by blowing cold air through the vents. The heat mode is used to raise the temperature in your home by blowing hot air through the vents. To check if your AC is set to cool, look at the thermostat. If it’s set to cool, the word “cool” will be displayed on the screen. If it’s set to heat, the word “heat” will be displayed on the screen. You can also check the set temperature to ensure that it is low enough to engage the air conditioner.
If your thermostat isn’t working, you can check the batteries. Most thermostats use AA or AAA batteries. If the batteries are low or dead, replacing them should solve the problem. Many people often forget about the batteries in their thermostats until something goes wrong. You’ll want to try to install good-quality batteries to ensure that they last for several months. You can also put your thermostat on the same schedule as your smoke detectors for checking and changing batteries.
There are many common problems that can lead to your air conditioner not working correctly. However, if your AC has stopped cooling and you can’t troubleshoot the issue yourself, the most important thing to do is to call a professional. There could be a number of problems with your AC unit that need to be addressed by a professional.
