You will always want to walk into your house when the temperatures increase rapidly during the day. It is more soothing if you can put on your AC and enjoy the cold air blowing from it. The worst nightmare comes in when you turn on the air conditioner, and it cannot blow cold air. Your AC can fail to cool off your home for many reasons, such as having the filter being dirty and setting the thermostat incorrectly. Figuring the specific problem is the key to getting your AC fixed. Below are some of the reasons that can make your AC not to blow cold air:
Often, your AC can be ruined by the thermostat settings. Setting your AC’s temperature higher than the warmth in your house can make it fail to automatically cool your home. If, for example, you set your air conditioner at 28°C and the temperatures in your house are at 24°C, the thermostat may fail to turn on. When the thermostat is on ‘Auto’ setting instead of the ‘On’ setting, it will hinder the AC from producing cold air.
You will have to investigate a little to figure out if it’s indeed the thermostat setting preventing your AC from producing cold air. Check if your AC ‘shut-off switch’ located at the shut-off box has been flipped. You will also need to confirm if the breakers are okay.
Once you have completed that procedure, reset your thermostat to the temperatures a few degrees cooler than inside your house. Though this may take a few minutes, you will begin to notice some changes if the AC is functioning appropriately. To confirm if there is any change, put your hands over the vents to feel if there is cold air being blown. If you don’t notice any difference after resetting your AC’s thermostat, there could be a problem with the internal wiring. It is advisable at this point to consult an expert for a solution.
According to Pearland Air Conditioning, The high temperature in your house is regulated by a liquid known as a refrigerant. It is this liquid that absorbs the heat from your home and eventually cools it off. Refrigerant may leak due to ice building up on the refrigerant line or outside the unit. You should turn your air conditioning unit off once the leak occurs since it may damage your compressor.
The following are ways you can identify a refrigerant leak:
Your AC’s furnace filter needs regular maintenance. It would help if you kept checking your air filter every 30 days to look out for any clogging. The filter should be cleaned or changed when clogged since it will restrict your house airflow. As a result, your home will be stuffy, dusty, and hot.
A condenser is typically an outdoor part of your air conditioning unit. Debris and dirt entering the condenser interfere with the process of pulling in the air and cooling it. You can gently wipe the dirt and debris from your condenser using water and soap and solve the issue. You should be careful enough to avoid bending or breaking anything in the condenser when wiping it.
A weatherproof cover can help to minimize then dirt getting in your AC when it is not functioning. The area surrounding the condenser should also be clear of overhanging branches, be weeded, and the plants around should be trimmed. On the same note, the condenser fan will not work correctly if it is broken. It is only a technician who can fix it if that is the case.
In the attic, the air duct system transports conditioned and clean air back into your house. With time air ducts weaken due to age, construction mistakes, and invasion by rodents. A damaged air duct lets the hotter air escape via the ducts to your home, giving a hint that your AC is not blowing cold air. It is wise to have your AC’s air ducts frequently checked by an HVAC expert for repairs.
A compressor operates as the air conditioner’s heart. It is responsible for moving the refrigerant inside and outside of the air conditioning system. A damaged compressor will require the outside part of the AC to be replaced, which is quite expensive. Again, an HVAC technician would be the best person to handle the issue.
An AC, which is either too big or too small, contributes to your condenser wearing out and hence making the AC fail to blow out cold air. Thus, it is imperative to know what AC unit size will be the best to use. You can consider the following factors when choosing your AC size:
During summer, the temperatures tend to be very sticky, hot, and humid. It is during this time that the need to have an air conditioner is felt. An AC that is big enough to regulate the sticky air and fight the warmth during this time would be the best.
The direction, size, and the number of your windows determining the size of an AC required. For instance, if your house has many big windows, you’ll need an AC which will accommodate the indoor temperatures and vice versa.
The air within your home is kept tight and efficient by your home insulation. Having poor insulation will require you to spend much on the AC. A larger AC unit will also be needed to cool a bigger home effectively.
The horrible moments when your AC cannot blow cold air during hot days can be solved by simply investigating and identifying the specific problem with your AC and resolving it. Sometimes it can be an issue that you can sort out by yourself while other times, a technician will be necessary.
