What Is Head Pressure In HVAC?

Let’s take a look head pressure in HVAC and what causes this cooling issue.

What Is Head Pressure?

The pressure that’s generated by the gas compressor of your air conditioning unit is known as head pressure. The head pressure is something to measure whenever you suspect a refrigerant issue.

While reasonable head pressure is nothing to worry about, it’s high head pressure that’s an issue. Schedule an appointment with the cooling professions if you believe high head pressure may be an issue in your AC system.

Signs Of High Head Pressure

Keep an eye out for these four factors below that could result in high head pressure.

Fan Motor Worn Down

You may notice some high head pressure if you possess a bad or worn down fan motor. Actually, this is the most common issue that causes high head pressure.

A bad fan motor can result from fan blades naturally wearing out over time. The blades wearing out can push debris outside the AC unit.

Refrigerant Issues

Refrigerant leaks can easily lead to high head pressure. This can also lead to the demise of your system, so call a professional immediately when you notice this problem.

Non-Condensing Gases

If you have done some DIY work on your AC unit, you may run into some confusion with the refrigerant system. High head pressure can be an unfortunate result of suspect DIY maintenance.

Dirty Condenser Coils

Coils in the AC unit can become dirty as time goes on. This can occur when the unit has not been inspected or cleaned in quite some time. It’s recommended to have the professionals maintain your AC system every spring.
