When it comes to refrigeration & HVAC, there are always questions about the condenser. What is a condenser? How does it work? How many types of condensers are there? Enough already! Don’t worry; we got you covered. Let’s kick a few basics out of the way, shall we?
A capillary tube is found in wide variety of refrigerators, water coolers, air conditioners and deep freezers. This component connects the condenser to the evaporator, and its length determines the amount of refrigerant at a specific pressure. Sometimes, issues can pop up that prevent cooling from happening. the capillary...

When technicians and facility managers search the web to learn about the refrigerant in the unit they're working on, there are four types that often...
In the United States, hydrochlorofluorocarbon (HCFC) refrigerants are being slowly phased out from production or being importing. The U.S. Environmental Protection Agency (EPA) still allows many of these types of HCFCs refrigerants to be used in repairs or retrofitting. However, without new production, the cost is becoming more...
R22 refrigerant is a colorless gas known chemically as hydrochlorofluorocarbon 22 (HCFC-22) and is one of several refrigerants that goes by the brand name "Freon." It's used in a wide variety of applications, including central HVAC,...
R134a refrigerant is an ethane-based hydrofluorocarbon used in a wide variety of refrigeration equipment, HVAC units and cars. Used as a primary replacement for R12 refrigerant, R134a refrigerant is considered a safe option because it has non-toxic and non-flammable properties and doesn't corrode. To help service technicians...
