Air Conditioning Repair Guide – Know Your Refrigerants

For those who like DIY air conditioning repair, or are hiring a professional to get the job done, should know about refrigerants as they are critical components of your AC.

The federal government has implemented a ban on CFC based refrigerants that are harmful to the ozone layer. Most modern day refrigerants are not harmful to ozone as they do not use CFC as an ingredient.


Ammonia is toxic but it’s lighter than air, thus, it never stays on the floor area, even if there is a leak. This is one of the oldest refrigerants known to man but is usually used in large commercial sector.

Sulfur Dioxide and Hydrocarbons

Sulfur Dioxide and hydrocarbons are also used in the air-conditioning system but are not very popular today.


Freon is a commonly used refrigerant in HVAC systems and other home AC units.

There are many other refrigerants, including water, used in air-conditioning systems, but some of them are banned due to the CFC content in it.

Although the government banned using Ozone-unfriendly refrigerants in newly installed air-conditioning units, there is no problem for using them in air conditioning repair or service on an older AC.

For instance, you can change the ozone unfriendly refrigerants in an existing unit with the same refrigerant, but it is not permitted with a brand-new unit.

Commercial Aspects Of Air Conditioning Service And Refrigerants

If you have a very old air-conditioning unit that uses refrigerants like R-22, which is ozone unfriendly, it is important to note that your air conditioning repair sessions are going to cost you a lot more in the future as a government imposed restriction reduced their production, and the price is also likely to get high.

If your unit is pretty old and requires a major overhaul, consider changing the unit with a brand-new one to avoid expensive air conditioning repair in future.

DIY Air Conditioning Repair – Knowing Your AC’s Motors

With an abundance of information online, DIY air conditioning repair is not a daunting task for today’s handyman. You can ensure longevity and uncompromised performance for many years provided that you’re doing air conditioning service regularly.

An air conditioner has at least 3 motors to send hot or cold air to the room. These motors play a crucial role in your AC and knowing about them and how they functions, is important for air conditioning repair.

Indoor Blower Motor

The indoor blower motor moves the air to cooling or heating coils based on the user set preferences and then through the air conditioning ducts.

Compressor Refrigerant Motor

AC compressor gas needs to be converted into a liquid for an AC’s functioning. If gas coil sealing and other measures to maintain pressure in the coils are not working, the compressor motor is weak.

Condensate Pump Motor

The duty of the condensate pump motor is to remove the condensate from the air handler.

Repairing The AC Motors – Things You Need To Know

In most cases, air conditioning repair is not needed to make the AC motors work. Most faults are a result of the circuit switch getting turned off during an overload or voltage fluctuation. All you need to do is find the cut-off switch and turn it on.

If your air conditioner unit is a modern one, chances are that the cut-off switch resets automatically.

In the worst case scenario where the motor has to be replaced, it is recommended to hire a professional as you will need a completely new motor. Being a very sensitive part of the air conditioner, the motors should be replaced professionally for the smoother operation of an AC.

Being an expensive repair job, you want to try and get this AC, and it’s parts, covered by a warranty.
