Why is my air conditioner not blowing cold air?

This week we are seeing record heat for what might seem like an unending stretch of days. With highs in the upper 90s, people are turning to their air conditioning system to provide comfort. But what if you turn on your air conditioner and it isn’t blowing cold air? Here are some of the most common reasons why your air conditioner might be doing this.

#1: Your filter is clogged.
Your air filter plays a very important role in the overall functioning of your cooling system. Not only does it filter the dirt and debris from the air to help provide you clean air to breathe, but it also affects how the system runs. Excess debris build up will impact airflow, which could cause your system to not do its job. Take out the filter every 1 to 2 months to check and make sure it is not dirty, and either replace it or clean it thoroughly. This will help prolong the life of your system too.

#2: Dirty coils.
Your evaporator coils will get dirty over time and if they are not cleaned well, it can affect the performance of your air conditioning system, making it more difficult to remove warm air from your home. If the coils are extremely dirty, more serious issues can occur like having the system completely overheat and shut off. Contact our team of experienced technicians at Specialty Heating and Cooling for a preventative maintenance appointment, where we will make sure that the evaporator coils are cleaned properly.

#3: Leaks.
Refrigerant is required for your air conditioner to do its job, but if there is a leak, then your home will stay warm and your system may not be blowing cold air. Refrigerant can be hazardous to handle, so make sure you contact our team of technicians to do the work if this is something you suspect as the problem. Another type of leak that can happen is an air duct leak. If there are leaks in your air ducts, the cool air may be escaping, instead of going into your home, where you need it most. Air duct leaks cause homeowners to lose hundreds, sometimes thousands of dollars each year. We can help with that. We are proud to use Aeroseal technology for our customers that are experiencing duct leakage in their homes. Contact us today for information on how Aeroseal may be right for you.
