AC Myth

AC Myth
There are many myths that float around in the HVAC world. In fact, there are so many, that we can’t keep all of them straight! Fortunately, at B&J Plumbing Heating & Air Conditioning Inc, we can lay all those silly myths to rest as we are knowledgeable and experienced in the HVAC industry. 

One common air conditioning myth we’d like to settle once and for all is the following: All the technician has to do is stick his gauges on the unit to tell if it is low on refrigerant.

The Answer:

Believe it or not, there’s no gauge to measure the level of refrigerant in a unit. The gauge that technicians use, is one of many tools used in the process that will inform our crews if the system is low or overcharged. Refrigerant gauges measure the pressure inside the A/C unit. 

As temperatures change inside and outside of the house, so does the pressure. Other factors that will change the temperature and pressure include the amount of air flowing through the unit’s coils, dirty filters and blower wheels, weak motors, duct restrictions, and more. 

With this being said, it’s vital for technicians to inspect, and if needed, fix any airflow issues before making any adjustments to the refrigerant levels. If the job isn’t done correctly, poor airflow could potentially lead to an overcharged unit, which can cause major damage to the A/C unit. Matters can get even worse if the damage is not detected for months or years. 

Don’t hire an inexperienced technician to handle your work. HVAC work is not a guessing game; each job needs to be done with the utmost precision to ensure your A/C unit lasts a long time and works properly. Enlist help from B&J Plumbing Heating & Air Conditioning Inc; we don’t guess at what we’re doing, because we know what we’re doing!
