Common Lennox AC Problems and How to Fix Them

When summer comes around it can be a nightmare trying to cool your place down and keep it comfortable. Having a properly functioning air conditioner is a vital part of making it through a hot summer. Lennox air conditioners are among the best on the market and are renowned for their quality. However, Lennox air conditioners are not without their faults and they can develop problems. Fortunately, there are some simple DIY solutions you can apply to common Lennox AC problems to resolve the issue.

Blower and Fan Issues

Air conditioners are made up of several components, one of which is the blower fan. This is a motor powered fan that is responsible for circulating air through your unit and throughout the rest of your home. If the blower fan is having problems, it’s likely to cause your unit to experience a decreased airflow. The most common issue for the blower fan is an issue with the motor, however other issues such as dust, hair and other debris accumulations can also block the fan from turning and result in a poor airflow. If your fan is having trouble it’s usually a matter of cleaning it out.

It’s safe to remove the cabinet from the outdoor unit and access the fan to clean it out. Some people are familiar with this process, however for those who are not it is advised to get a professional to inspect and clean your unit. Regular service of your LENNOX air conditioning unit is important in maintaining its accuracy and efficiency, which saves you money on the long run.

Insufficient Cooling

An A/C unit experienced insufficient cooling can be annoying and hit your wallet at the same time. Insufficient cooling is caused by a variety of problems, but they can be sorted out with careful troubleshooting and expertise. A loss of cool air or a weak flow of air needs to be investigated as soon as possible.

The most common cause of insufficient cooling is either a clogged filter or a refrigerant leak. Before investigating it’s important to check the unit’s filter and clean it out if it’s dirty. If that doesn’t solve the problem then the refrigerant levels should be checked and refilled if needed. Refilling the refrigerant is a task best left to the professionals.

It’s also worth checking out if the coils of your LENNOX air conditioner have accumulated dirt. Cleaning dirt from the coils with a simple brushstick can improve your air conditioner’s efficiency significantly and help solve the issue of insufficient cooling. If the issue persists for more than a couple of days, it’s time to call on a professional.

Poor Air Quality

Nowadays, concerns about air quality in the home have become a priority for many homeowners. The sad truth is that the air inside of a house can be many times more polluted than the air outside. Air conditioners do not just affect the temperature, they also filter out air pollution, dust, smoke, and pollen particles to protect you and your family from potential health risks.

If you experience poor air quality in your home it may be due to a malfunctioning air filter. Air filters are intended to clean the air as it passes through the air handler and they must be changed or cleaned regularly. In most cases, masks, curtains and sheets should be washed regularly as well to prevent air pollution.

A professional inspection of your air conditioning system can also be beneficial. A technician can inspect the unit and replace any broken, damaged, or inefficient components in your unit. Making sure that the unit is free of dust and debris is also key in keeping the air clean in your home.


Maintaining a properly functioning air conditioner is important for keeping your house cool in the summer. Lennox air conditioners are among some of the best on the market, however, problems can still arise from time to time. Fortunately, many of the common Lennox AC problems can be easily solved if you follow the advice provided in this article or opt to call a reliable and trusted appliance repair service.
