Why Is My AC Not Blowing Cold Air?

Published October 12, 2022 / By Big Bear Heating & Air

If you’re experiencing problems with your AC and it’s not blowing cold air, you’re not alone. This is a common issue that many homeowners face during the summer months. Thankfully, there are some things you can do to troubleshoot the problem and hopefully get your AC up and running again. In this blog post, we will discuss some of the most common reasons why an AC might not be blowing cold air, as well as some tips on how to fix the problem.

How Does An Air Conditioner Work?

Your air conditioner works by circulating cool air throughout your home. The cool air is created by evaporating refrigerant, which absorbs heat from your home’s air and then circulates back outside. If your AC is not blowing cold air, the problem could be with the evaporator coils, which may be frozen or dirty. Another possibility is that the air filter is dirty and needs to be replaced. In some cases, the problem may be with the thermostat, which may need to be recalibrated.

What Are The Different Kinds of Residential Air Conditioners?

There are three main types of residential air conditioners: window air conditioners, central air conditioners, and portable air conditioners.

  • Window air conditioner
  • Central air conditioners
  • Portable air conditioners

Window air conditioners are a popular type of AC unit due to the flexibility. They can be installed in any window near a plug. Window units are typically less expensive than central air conditioners, but they also have lower energy efficiency ratings.

Central air conditioners are the most common type of AC unit, and they are typically installed outside of your home. They are more expensive than window units, but they have higher energy efficiency ratings.

Portable air conditioners are the least popular type of AC unit, but they are a good option for people who do not have central air conditioning. Portable air conditioners can be moved from room to room and they have higher energy efficiency ratings than window units.

Common Causes of Air Conditioning Issues

There can be a number of causes for problems with your AC, including:

  • Improper installation
  • Incorrect sizing
  • Dirty filters
  • Frozen evaporator coils
  • Leaky ducts
  • Faulty thermostat

If you are experiencing problems with your AC, it is important to troubleshoot the issue as soon as possible. Some of the most common causes of air conditioning issues include:

Dirty air filter – If the air filter is dirty, it can cause the AC unit to work harder and eventually freeze the evaporator coils. The best way to prevent this is to replace the air filter every month.

Frozen evaporator coils – If the evaporator coils freeze, the AC will not be able to produce cool air. This can be caused by a variety of factors, such as a dirty air filter, low refrigerant levels, or a blocked airflow.

Leaky ducts – Leaky ducts can cause the AC unit to work harder and result in lowered cooling efficiency. In some cases, it may even cause the AC unit to shut down completely.

Faulty thermostat – A faulty thermostat can prevent the AC unit from turning on or cause it to cycle on and off too frequently. This can be a major problem, especially in homes with young children or elderly residents.

What Causes Air Filters To Get Dirty?

The most common cause of dirty air filters is insufficient airflow. This can be caused by a number of factors, such as blocked vents, dirty coils, or a clogged air filter. In order to prevent your air filter from becoming dirty, it is important to ensure that there is sufficient airflow through your HVAC system.

Ducts Are Leaking Air

If your AC unit is not blowing cold air, one of the possible causes is leaky ducts. Leaky ducts can cause the AC unit to work harder and result in lowered cooling efficiency. In some cases, it may even cause the AC unit to shut down completely. To prevent your AC unit from experiencing these problems, it is important to repair any leaky ducts as soon as possible.

How To Troubleshoot A Faulty Thermostat

If you think that the problem with your AC unit is a faulty thermostat, there are a few things you can do to troubleshoot the issue. First, try replacing the batteries in the thermostat. If this does not solve the problem, you may need to re-calibrate the thermostat. To do this, you will need to consult your owner’s manual.

How Much Does AC Repair Typically Cost?

The cost of AC repair can vary depending on the severity of the problem. However, in most cases, it will cost between $100 and $600 to have a professional technician come out and fix the issue.

If you are having problems with your AC in Sarasota, don’t hesitate to contact a professional Sarasota AC repair company. They will be able to diagnose the problem and recommend a course of action.
