You might call it Freon or maybe know it by another brand name, but the chemical refrigerant that’s inside your AC is an essential component allowing the system to do its job. Without refrigerant, your air conditioning system is nothing more than a large central house fan. Fans can help out a bit in hot weather—in fact, we recommend homeowners turn their ACs to “fan only” mode during the milder hot weather to help save energy. But if you want to endure an intense Texas summer, you’ll need an air conditioner system that actually draws heat from the air to cool it down. And for that, the AC needs refrigerant.
But people often don’t understand exactly how refrigerant works in an air conditioner. For example, a question that HVAC professionals sometimes hear from customers is when they should have more refrigerant put into the system. The answer is, “Hopefully, never.” We’re here to give you some facts about refrigerant, which will help you know when your AC needs repair work done.
