Is your AC blowing out lukewarm air instead of that refreshing, cool breeze you were hoping for? 70 degree air may not sound terrible, but when you’re sweating in the summer heat, it’s far from comfortable. So why is this happening? There could be a few reasons why your AC is blowing out air that isn’t quite cold enough. In this blog, we’ll explore the most common causes of this frustrating issue and what you can do to fix it.
Don’t let your AC lower your comfort level this summer – let’s take a look at why your AC is blowing 70 degree air.
How AC Units Work
If your AC unit is blowing air at 70°F, there might be a few reasons why. To understand how AC units work, let’s delve into it a bit. Air conditioning units are designed to remove heat and moisture from the air.
They do this by circulating refrigerant through a cycle of evaporation and condensation. The refrigerant absorbs heat as it evaporates and releases it as it condenses. This cycle is repeated over and over again until the desired temperature is achieved.
So if your unit is blowing air at 70°F, it might be an issue with the refrigerant levels or the compressor. Low refrigerant levels can cause the unit to blow out warmer air, while a faulty compressor can restrict the flow of refrigerant and prevent it from cooling properly. It is best to have a professional come and inspect your unit to diagnose the issue and make necessary repairs.
Don’t ignore the issue and suffer through the heat; with the right repair, your AC unit can be blowing 60°F or lower air in no time.
Heat Absorption and Cooling Process
When it comes to beating the heat, air conditioning units are a game-changer. But have you ever wondered how exactly they work? Well, the answer lies in the science of heat absorption and cooling. You see, AC units utilize a fluid known as refrigerant, which absorbs heat from the air in your home and cools it down before blowing it back out.
The refrigerant circulates through a closed system of pipes and coils, alternating between gas and liquid states as it absorbs and releases heat. But how does it absorb heat, you ask? Well, the refrigerant starts off as a cold liquid that evaporates when it comes into contact with warm air. As it evaporates, it draws heat from the surrounding air, essentially cooling it down in the process.
Once the refrigerant has absorbed enough heat, it is compressed by the AC unit’s compressor, which increases its temperature and pressure. The hot, pressurized refrigerant is then passed through another set of coils located outside of your home, where it releases the absorbed heat into the outside air. This allows the refrigerant to cool down and return to a liquid state, ready to start the process all over again.
So, the next time you turn on your AC, remember that it’s all just a clever use of science and fluid dynamics!
Thermostat Malfunction
AC units work by using a thermostat to control the temperature in your home. When the temperature rises, the thermostat sends a signal to your air conditioning unit to turn on, and when the temperature reaches the desired level, the AC shuts off. However, a malfunctioning thermostat can cause a host of problems, including inconsistent temperatures and higher energy bills.
If your AC unit seems to be running constantly or if you notice temperature fluctuations, it might be time to check your thermostat. One way to test your thermostat is to set it lower than the current temperature and see if the unit kicks on. If not, you may need to call a professional to diagnose and repair the issue.
Remember, a properly functioning thermostat is key to keeping your home comfortable and your energy bills under control.
Troubleshooting Your AC System
If your AC system is blowing out 70 degree air, it’s likely not functioning as efficiently as it should be. One possible cause for this could be dirty air filters, which can restrict airflow and cause the system to overwork, resulting in warmer air being blown out. Another possibility is a refrigerant leak, which can cause cooling performance to significantly decrease.
If this is the case, it’s important to contact an HVAC professional to fix the issue before it worsens and causes damage to the system. Another potential cause is faulty ductwork, which can result in cool air escaping before it reaches its intended destination, and warm air being pushed through the vents instead. It’s important to check your ductwork for any visible leaks or damage to prevent this from happening.
By staying on top of maintenance and troubleshooting issues, you can keep your AC system running as efficiently as possible and prevent any costly repairs down the line.
Check the Air Filter
When it comes to troubleshooting your AC system, one of the first things you should check is the air filter. A dirty air filter can cause your AC system to work harder and less efficiently, which can lead to higher energy bills and potential damage to your system over time.

Simply locate the air filter housing unit, remove the old filter, and replace it with a new one. It’s important to make sure you have the correct size and type of filter for your system, so double-check before making a purchase. By regularly checking and changing your air filter, you can improve the overall performance and longevity of your AC system.
So don’t ignore this quick and simple maintenance task, it could save you a lot of money in the long run!
Inspect the Evaporator Coil
Inspecting the evaporator coil is crucial in troubleshooting your AC system. The evaporator coil plays a vital role in the heat transfer process, absorbing the heat from your home’s air and cooling it down. However, over time, the coil can become dirty or even freeze over, impeding its efficiency and causing your AC to malfunction.
Therefore, it is essential to inspect the evaporator coil regularly. You can do this by removing the paneling in your air handler or blower compartment and visually inspecting the coil. If the coil appears dirty or covered in ice, it’s time to call in a professional technician.
Ignoring the issue can cause further damage to your AC system and result in higher energy bills. So if you notice anything suspicious or unusual about your AC’s performance, don’t hesitate to contact a professional for an inspection. Remember to clean or replace your air filters regularly to prevent accumulation of dirt on the evaporator coil.
Ensuring that your evaporator coil is functioning efficiently will save you money in the long run and extend the life of your AC system.
Test the Thermostat
If your air conditioning system suddenly stops working, one of the first things you should check is the thermostat. A malfunctioning thermostat can cause your AC to stop working and leave you hot and frustrated. To test your thermostat, start by turning off your AC at the circuit breaker.
Then, remove the thermostat cover and check the wiring to make sure everything is securely connected. Once you’ve checked the wiring, set the thermostat to a temperature that is a few degrees lower than the current room temperature and wait a few minutes. If you don’t hear your AC turn on, try replacing the batteries in your thermostat.
If that doesn’t work, it may be time to call in an HVAC professional to diagnose the issue. Keeping your thermostat in good working order is essential for the smooth operation of your air conditioning system, so make sure to test it regularly. Keyword: Test the Thermostat.
