#2: There may not be enough oil in the system.
In a properly operating A/C system, refrigerant carries oil throughout the system, lubricating parts along the way. If you do have a refrigerant leak, some of the oil leaks out with it. Adding more refrigerant with an A/C recharging kit doesn’t replenish the lost oil. Continuing to run your A/C in this condition can cause damage to internal parts and lead to more expensive repairs later.
#3: Moisture is the enemy of an A/C system.
When oil and refrigerant leak out, moisture and air get in. This wreaks havoc on your A/C system because moisture reacts with refrigerant and oil to create acid and sludge. The sludge interferes with the transfer of heat and the acid eats away at internal parts and seals. In both cases, the system is rendered ineffective and parts break down prematurely.
#4: A/C recharging kits are often used inappropriately.
What many DIY’ers don’t know is that proper recharging of an A/C system is done by weight, not by pressure. Since DIY A/C recharging kits come only with a pressure gauge, and you have no idea how much refrigerant was lost or needs to be added, the systems often become overcharged.
The bottom line is that DIY A/C recharging kits may offer a temporary solution but rarely a long term one. And, they can cause more damage and result in the need for even more expensive repairs in the future. Instead, you can trust our expert technicians to fix the problem right the first time and get your A/C running efficiently again.
