What Is Involved in Air Conditioning Replacement?

Posted by

AC units that are older than 12 years usually need to be replaced, as they have outlived their life expectancy. The replacement of an old system requires the removal of the outdoor compressor and the indoor air handler. The entire process should be performed by a licensed professional with the tools that can remove the refrigerant and clean/replace the ductwork.

Calling a HVAC professional for air conditioning replacement and duct work is a smart choice for any homeowner. A professional will have the skills and tools necessary to disconnect and replace the central unit to clean or rerun ductwork wherever it is needed. The professionals will deal with the central unit, the outdoor compressor, the refrigerant, and the ductwork.

The Central Unit

The central air conditioning unit that keeps the air in your home comfortable in the warm summer months is usually a split system with an air handler and a compressor. The air handler is usually located somewhere on the main level of the home or up in the attic. It contains the blower (fan) and air exchanger. The compressor is usually located somewhere on the outside of the home, far away from windows, due to its ability to generate noise.

The professional will disconnect the compressor and the air handler from the air duct system and replace it with a new unit. Once the air duct system is cleaned or replaced, the professional will hook everything up including the electrical connection, and recharge the refrigerant so it can produce cold air again.

Air-Conditioning Duct Work

The cool air from your air conditioning system is delivered to all the rooms in your house including hallways and bathrooms through a hidden network of rigid or flexible ducts. Based on your home’s duct work condition, the contractor will choose to clean, repair or replace the system. To work efficiently, the air duct must be as airtight as possible. This allows the prevention of air from escaping, which would cause the system to become highly inefficient.


The refrigerant in the air-conditioning system is strictly controlled by the EPA (Environmental Protection Agency). Their tight controls minimize the escape of Freon refrigerant gas into the atmosphere. Only certified technicians with the proper equipment are allowed to charge, or fill, your air conditioning system with refrigerant to ensure it is functioning properly.

Usually, in an old system, the air ductwork does not necessarily need to be changed. However, if your AC unit is older than 12 years it most likely has outlived its life expectancy. A qualified, licensed, competent HVAC contractor will be able to quickly replace your old unit with a new one. Once installed, it will run more efficiently, creating lower utility bills and producing cleaner air for your home.

Customer Reviews

This was an exceptional experience! We woke up to our A/C on but not cooling (it was 6am and already 81 in the house). The person who set up our appointment was very nice, able to get us seen same-day, and let us know of some options to help save us money.

-Christy Cormier

The service from Sam and Chris was excellent! They were very knowledgeable and professional. They were able to answer all of my questions and completed all of my electrical issues. I will definitely use them again for future jobs. Thank you!

-Adrienne Beal

From the get go I could tell that the Snyder employees were truly professionals and didn’t push to make sales like other companies I’ve talked to my whole life. They took the time to explain so that I could make a decision. The installers and later the duct cleaners were very respectful during their work here. Thank you.

-Mike Daniels

The technicians were all so professional and took great care of us! We’re so thankful for their expertise. Great and easy communication with the call center. We will definitely use them again!

-Crystal Hill

Snyder provided an amazing experience from start to finish. Most of us dread getting estimates with pressuring salespeople. Erik was a great guy, explained all my options and didn’t try to pressure me to act quickly! Justin followed up with my husband and I to offer further assistance in our decision. Again, no pressure, just helped with our follow up questions.

-Michele Bauer

Snyder was easy to get in contact with and had availability the next day. Clint came out and needed some parts so had to reschedule us for the next day for installation. He did a great job converting our old 3 knob shower to one. Looks great! Professional and courteous. 100% recommend this company, especially Clint.
