Reasons Why Your AC is Not Cold

Is your aircon no longer cold? You do not want to awaken or return home to learn that your air conditioner is malfunctioning. This is extremely unpleasant and can pose health concerns to you, your family, and any household pets.

You should take prompt action as soon as you become aware of an issue. Do not wait until the heat gets intolerable before seeking relief. Always contact a professional for HVAC servicing when in doubt.

There are various potential causes for your HVAC system to stop circulating cold air. Some are straightforward and may be resolved instantly, while others require the assistance of an expert.

Here are some things to consider if your air conditioner is no longer blowing cold air and how to remedy the problem.

Low or Leaking Refrigerant

The refrigerant, which is often Puron or R410A, is the chemical that initiates the whole process.

If your central air conditioner is not producing cold air, the problem may be the refrigerant. The device might be low on refrigerant and require replenishment.

A leak most likely causes this. A leak not only prevents the air conditioner from functioning correctly, but it can also lead to additional problems within the home. When it isn’t cool enough, for instance, humidity levels might rise in your house, making it feel hotter than it is.

If you suspect there is a refrigerant leak, contact a skilled HVAC technician immediately. Unless the leak is substantial, it can be difficult to effectively diagnose and repair leaks.

The Filter Is Unclean or Clogged

Filters that are filthy or clogged are a common issue with air conditioning equipment. These filters capture hair, lint, dust, and pollen year-round. If they are not frequently emptied, it does not take long for them to be filled.

When this occurs, air cannot flow properly into the home, and your air conditioner may shut off due to a lack of air. Without a functioning air conditioner, the inside temperature increases. If left for too long, blocked filters can potentially accelerate the deterioration of components. Even the evaporator coil and condenser can be affected, creating a greater issue.

In addition to ordinary cleaning every three months, the filters should be replaced. You might need to do so more frequently if you have indoor pets.

You should be able to change your own interior air filters effortlessly. But, if you do not know which filter to use, an AC expert can assist you.

There is a Problem with the Condenser or Evaporator Coil

Even while the aforementioned filters do their best to keep the coils clean and working efficiently, the coils will eventually wear out.

Because of the continual wetness, your interior evaporator coil is susceptible to mildew and even mould growth. (UV lamps can protect against this and purify the air.) Low refrigerant levels inside a system can also cause coils to freeze.

Problems with the coils may create significant problems within the air conditioning unit and should be addressed by a qualified HVAC technician as soon as possible.

With time, the condenser might also deteriorate. Check this as well if your air conditioner is not delivering cold air and no other cause can be identified.

AC Not Generating Cold Air – Thermostat Problem

The thermostat is where everything begins. The air conditioner will not activate until the room temperature exceeds the regulated setting. First, confirm that the thermostat setting has not been altered. Next, ensure that it is set to automatic or cool. Occasionally, a thermostat will be set to heat rather than cool, causing the issue.

If it is properly set and the air conditioner still does not turn on, the thermostat may be at issue. If it requires batteries, inspect and, if required, replace them. If it does not address the issue, it is necessary to contact a skilled AC technician.
