Precautions before Using a Home AC Recharge Kit

Precautions before Using a Home AC Recharge KitIn this day and age, we can buy almost anything and everything over the Internet with the prevalence of online stores; and this includes recharge kits for your home cooling system. Air conditioning units are considered necessities in many homes and when they fail to deliver the required cooling level they can cause a number of unwanted problems. Before you go out and buy a home AC recharge kit you should be aware of some of these precautions.

Perform a System Check

However, according to many air conditioning technicians, most of the time the real cause of the problem is not the need to recharge the AC unit, but rather inadequate maintenance.

  1. Before purchasing a home AC recharge kit make sure that you do routine maintenance on the unit by cleaning out or replacing, if necessary, the air filter. Proceed by cleaning the condenser and evaporator coils where refrigerant passes to deliver cool air. You must be aware that if refrigerant is added to a unit with dirty evaporator or condenser coils, it may be damaged.
  1. Remove obstructions from the blower fan that can prevent its normal operation. Do the same with the condenser fan to ensure that there is enough safe to allow air to pass through the coils to remove the hot air from your home.
  1. Make sure that the insulations are intact and that any joints or connections do not have leaks. These are commonly the cause of minor problems that can easily escalate to major ones that drastically degrades the efficiency of cooling units.

Know Your Refrigerant and Manifold

It is important for homeowners to understand that a home AC recharge kit is not a fix-all remedy. This is because there are different types of refrigerants in use for modern-day cooling systems. Check the product manual or the side of the AC unit for a manufacturer’s specification on whether your system uses R410A or R-22 refrigerant.

The type of charging manifold is also important. Not all AC units make use of quick connect adaptors like the inverted flare Schrader valve. Although this type of connection has been established in many tests to prevent refrigerant loss better, the choice of still remains a manufacturer’s prerogative.

Having the wrong charging manifold set will not only prevent effective system charging but also compromise the dangerously high refrigerant pressure in the unit.

Safety Comes First

Safety First When Using Home AC Unit Recharge KitSome people may think that this is basic, but, many homeowners do not realize that the thermostat circuitry serves as the on and off switch of the air conditioning system. Although cutting off power by unplugging the unit will turn it off, the cooling system remains at an on state once it is plugged back in.

You need to ensure that the thermostat is turned off before unplugging the system as part of a safety precaution to avoid possible refrigerant poisoning that can cut off oxygen supply to vital organs like the lungs.

In small doses it can cause headaches, heart palpitations, eye irritations, and dizziness among others. You need to do this before hooking up the home AC recharge kit to ensure safety for everyone.

The dangers to self and the environment are primary reasons why the air conditioning industry is a highly regulated one. You can even be slapped with penalties of up to $32,500 daily for the release of refrigerants to the environment.


Eventually, all air conditioning systems will become ineffective over time. Using a home AC recharge kit is obviously a cost effective measure to restore cooling efficiency, just make sure that you take heed of these precautions.
