AC not blowing cold air (but running): 8 common causes + fixes
What’s wrong with this air-conditioning? If your air conditioning units are not working correctly, this is a common problem. It’s no bad experience if we can only watch the AC run and not cool down (blowing air temperatures of 88 to 90 degrees Celsius during summer). You can save electricity while you sweat at home. Approximately 30-30% of homes have a “cool air conditioner that doesn’t blow cold air”. Initially, this could be a problem. All air conditioners are designed to cool the house. It doesn’t cool your house, it doesn’t do their work correctly.
AC doesn’t blow cold air: 9 reasons & their solutions
All homeowners have nightmares about this situation. Temperatures have skyrocketed and your air conditioner is not blowing any cold air. Unless you can determine the problem quickly, everything becomes very uncomfortable. You know you need the air conditioning turned off before you go. Do not be miserable anymore. Let’s take a closer look at what can help keep your colder air in check.
Thermostat Set Incorrectly
Make sure the thermostat in your house has a temperature that’s either auto-cold or warm. A cooling system won ‘t work once the ambient temperature exceeds the temperature of the room. It’s essentially necessary to check the temperature of the thermostat. Often, thermostats turn on heating rather than cooling, and that may cause a problem. Check the temperature settings if someone else is doing this. Something could be wrong with faulty air conditioning. Turn on a warm thermostat and then turn it back down to cold when you are off. After a few seconds you should see if any warm air is coming from the register.
Issue with Condensers
A condensing coil blockage may be the cause of an air conditioner not cooling the air inside the room. A poorly conditioned condensing machine can reduce the system’s energy efficiency without the cool air from registers, or worse, the failure of the system, or the damage of compressors resulting from over usage. The condensing fan draws air to the outdoor unit by circulating the cooled condenser wire for the removal of heat from your house. The condensing unit operates continuously. Often dirt, grass or air particles can be collected around the edges of the coils, clogging them with air.
Have you changed your filter?
You may not think that filter helps with the cooling process, but the filters help. If your air filter is not regularly checked and cleaned your air conditioner might be inefficient. A central air conditioner unit containing an obstruction of filtration may limit air movement into your home and affect a variety of ac parts such as evaporator coils. Air particles will not only disappear from air, but may be dust and other stuff that may have developed from it. You should check the filter every 30 minutes, change the filter if necessary, or clean the filter. See details here.
Clear the clogged condensation drain
Air conditioning helps remove humidity from the air. A condensation drain hose is used to redirect water into your floor drain. A condensator drain can become blocked by mold or algae during this period. Often the AC blows hot air while others close completely after that. Simple DIY Fix: Find a drain line that has a condensation outlet (usually a utility room) that you can check visually to see if they contain obstructions. Ensure that the hole is cleared using a small screwdriver or other thin tool that can easily reach the bottom.
AC not blowing cold air: 10 possible reasons this happens
It can be one of several reasons your AC unit is not producing cold air. There’s quick AC repairs while others require professional help. If your Air Conditioner produces no air conditioning, it may need repairs. It is also important to contact an HVAC contractor when you have HVAC problems. For millions of people in the US, these cooling devices provide a reliable cooling source for their homes during the summer. Summer heat can only warm indoors in your home, causing health hazards in your family and your animals.
Is your condenser dirty?
The air conditioners outside have condensers on the outside. If dirt comes in it affects the process. It has to work harder to cool down the air you’re cooling off. Similar problems can be encountered with filtering. Fortunately, cleaning out your condensing units outdoors is an easy task. The soap and water can easily clean out any accumulated residue. The hose is easily pushed by the hand. If your air conditioner does not function properly, you need an appropriate weatherproof cover to prevent scuffing.
Is your thermostat set correctly?
Some thermostats are responsible for uncooperation with central air cooling systems. If the thermostat has a higher value, it can’t even activate itself. Suppose the room temperature is 24°C and the air conditioning temperature is 28°C. It may also not work when the auto setting is set rather than on. At that point there must be investigations underway. How do I make my AC fan shutoff switch flip off when it comes out of a shutoff box? How does the alarm work if it is not broken?
Issue with Evaporator Coil
evaporator coils are part of an HVAC piping system. If your house has heating pumps, your evaporator coil can be contained within the fan coil cabinet unless you install an indoor fan coil. It’s activated to remove air temperature by cooling heat. During these cycles the next stage of this cycle will allow warmer, better air flow into the home. The cylinders could be stuck to the cold water when it’s too hot to heat the air. Usually frozen coils are present in evaporators.
Is there a refrigerant leak?
The refrigeration fluid flows through air conditioning units and is compressed to a constant rate, reducing and enhancing the cooling system. There’ll always be re-use of it if there’s a replacement. In cases of leaks, however, they are less effective at absorption of heat. This decreases the temperature. It is possible that refrigerant leaks are a simple thing to detect. The HVAC professional will take the trouble out of your house.
Know when it’s time to call a HVAC pro
If your HVAC system doesn’t cool up after doing the DIY above steps, it could be the result of leaky compressors. Freon has federal regulations that require only licensed HVAC professional work with Freon equipment. Depending on how many years old your system has been in service, or how old your system is, you could need a new compressor. All the problems have been dealt with in a professional way so give us your time.
A: I’ve just turned on the air conditioner for the summer but I just can’t get comfortable. Why is my air conditioner not cooling? How can I fix it?
The colder summer air would be a big problem if there was no air conditioning. When you contact an HVAC expert, you can easily resolve the problem and reduce the cost of a house call. Air Conditioning is performed using a simple principle known as phase conversion. It is possible that AC fans blow hot air from a number of different causes. The following can be inspected if the air conditioner doesn ’ t cool the room.
What causes air conditioners not blowing cold air?
This guide is organized into three separate sections. If your AC doesn’t work, it is necessary to repair it yourself. Alternatively, you could contact an HVAC technician. If you know what causes a cooling fan to blow cold air you can quickly fix this problem. If there is a problem with the AC unit blowing cold air we may divide the problem by three categories:
1 AC doesn’t blow cold air due to basic electrical problems (Blown Fuse, Tripped Breaker)
We will start by covering some basic things. The air conditioning system requires electricity to keep air flowing. In a case where the compressor doesn’t receive enough energy it may compressed R410A or R22 refrigeration gaseous fuel. This means no thermal exchange and that air conditioning can blow the same-temperature air. First check cable. It should connect properly to the outlet. Use the correct voltage. The bigger 240 V – 240 V is required in larger AC units. Make sure there’s a problem with the power cord. I wonder if anyone plugs into the AC or the fans? What about you? That is a standard response.
2 Faulty Thermostat Preventing AC Unit From Blowing Cold Air
The thermostat controls the air conditioner. The problem with thermostats can be identified by difficulty. If the thermostat is not cooling correctly, you can check the basic thermostat problem listed here. Batteries within thermostats can help to prevent cold air from being released. The batteries on your thermostat are sometimes fragile and even if there is very little use.
Why is my AC blowing cold air but not cooling the house?
The air conditioning system blows cold air but cannot cool the house, causing leaking air inside the home. Make sure everything is closed. When an air conditioner is colder than room temperature, this might not be what’s needed.
Dirty Air Filter
They keep the components inside the system cleaner and operating more efficiently, which helps to maintain the air in your home better. A dirty air filter might obstruct airflow and reduce the amount of heat your home is able to absorb. It can lead to the system shutting down in more serious situations. Find the air filter for your system, turn off the power, take out the filter, and look.
Air Conditioner Running
If you find a leak, or suspect you have one but aren’t sure where to look, stop using your air conditioner right away and get in touch with us. You should not leave your air conditioner running if you suspect an issue- an HVAC professional will handle the issue for you. Important : If you do have a refrigerant leak, you should not try to fix it yourself.
Indoor Air Handler Unit
Air conditioning systems are more than just the condenser unit (the AC unit or heat pump) sitting outside your home. Typical split-system air conditioners have a lot of moving parts, including an indoor air handler unit (furnace or fan coil), an evaporator coil, air filter, thermostat and copper tubing (refrigerant lines) that connect the indoor and outdoor units.
Condenser Fan Draws Air
A dirty condenser unit may result in a system’s energy efficiency being reduced, with no cool air from the registers, or in the worst-case scenario, system failure or compressor damage as a result of overuse. The condenser fan draws air into the outdoor unit through the condenser coil to remove heat energy from your home as long as it is in operation. Between the fins, dirt, grass, and other airborne particles can build up, clogging the coil.
Why is my AC running but not getting cold?
Depending on how well the condenser has run, it may cause the clog in your condenser’s coil. When properly functioning, the condenser fan draws air through the condenser and draws energy out the outside.
You know you should have looked at your air conditioner before turning it on but don’t spend any more time feeling miserable. Let’s walk through the list of things you can do to get the cold air blowing again. 1. Is Your Thermostat Set Correctly? Often the thermostat is the problem behind an uncooperative central air conditioning system. If your thermostat is set at a higher threshold, it might not actually be turning on.
Should I turn off AC if it’s not cooling?
Stop this. We always advise the customer to do so if their AC does not cool correctly. Unless your HVAC technicians are ice-free, they cannot fix the issue until the frozen ice melts away.
The gas then cycles back to a condenser coil unit (located outside) where it cools back down to a liquid and the cycle repeats itself over and over. If your AC system is blowing warm air, several culprits may be to blame. The following are a few things to check when your air conditioner is not cooling your space.
