But first, you want to make sure your refrigerant is full (some products already contain fluorescent coloring). My outdoor ac on cool is blowing cool air out of the condensing unit not warm air like my other unit condensing unit.. This is at a church . The compressor sends compressed liquid refrigerant to the expansion valve or orifice tube, just before the evaporator. hbspt.forms.create(formDef); The AC only works when the car is cool. 50% { I checked the refrigerant pressure with the engine on/ac on high and it falls into the “full” level. 20% { } There are five major components to your car’s A/C system that enable this pressure-temperature exchange: Here’s how all of these components work together: When you turn on the A/C in your car, you activate the compressor which starts pumping refrigerant throughout the system and turns the refrigerant inside it into a high-pressure gas. That means when refrigerant from the high-pressure side loses pressure, it rapidly drops in temperature. Air in a car AC system decreases the system’s cooling ability because it takes up space in the condenser, yet it doesn’t condense. If this is the case, be sure to take it into a mechanic as quickly as you can. Find out what could be causing your car air conditioner to blow cold then warm! gtag('event', 'conversion', { 90% { Nobody enjoys driving a vehicle that needs repairs, especially if it’s something as vital as your AC system.
