AC Repair

If you notice that something is not quite right with your air conditioning unit, you want to get it inspected and repaired as quickly as possible. Air conditioning problems can grow quickly, and a small issue can turn into a much larger one that can prevent your unit from working.

Heat Pumps

A heat pump works in reverse to cool a space. Let us help you select the right heat pump for your home and care for it for you.

Edwardsville Indoor Air Quality Services

Indoor air quality is important. That’s why BEL-O Cooling & Heating Inc provides services for the following air quality services in Edwardsville, IL:

Air Cleaners

If you have anyone in your home who suffers from allergies or breathing issues, such as asthma, an air cleaner can help you to remove imperfections from the air that can trigger attacks. An air cleaner is able to remove dust, dander, and dirt from your air. 

Air Purifiers

If you have an individual who is immuno-compromised in your home, an air purifier may be a great tool to install. An air purifier not only cleans the air, but sanitizes it as well. This means that the air purifier can also kill germs and bacteria, making your home a bit safer for those who are more prone to illnesses.

Duct Cleaning

It is recommended that people have their ducts cleaned every two to five years. Your ducts can be filled with dirt, dust, and debris. When your heating or cooling unit kicks on, the air that the unit produces blows that dirt and dust into your home, making it dustier and dirtier than it needs to be. Duct cleaning keeps your ducts as clean as possible.  


Thermostats can be connected to your heating and cooling devices, as well as your air-cleaning devices to help ensure that these devices regularly turn on and off.
