An air conditioner condenser is quite heavy. It isn’t something that we think about on a weekly or even yearly basis as homeowners. We buy our homes and the air condenser unit usually has some kind of concrete slab under it from a time long ago and far away.

So what do you do if it isn’t level anymore?

Or it isn’t structurally sound?

What if you are getting a new condenser and don’t have any foundation at all? This article will discuss the in’s and out’s of purchasing an AC condenser pad and explain why you need one in the first place.

The Purpose of a Condenser Pad

As the air conditioning condenser vibrates with continual use on the same surface over a period of time, it can sink into the ground or cause damage to the unit. That is why everyone needs a good AC condenser pad to help support and contain the unit over time.

This expensive piece of equipment needs to be properly supported. To help the unit survive harsh winters or summers a quality waterproof pad is essential.

Condensers also accumulate water as it does its job making them weigh even more. This can put significant strain on the lines and tubes that run underneath the unit. It is crucial that the unit stay dry as well as level to extend the equipment’s lifespan and functionality. Whether you decide to go concrete or pre-fab, having some kind of support system is necessary.

Why Not Just Pour Concrete?

Concrete is the more traditional, tried-and-true way of stabilizing an AC condenser. What is most appealing about pouring concrete is how durable and permanent it can be.  However, concrete’s biggest pro can also act as its biggest con.

Over time the weight of the unit can cause the concrete to settle deeper into the soil below. This could put a strain on the copper coolant tubes and electrical lines. While the unit itself may stay dry, it can become uneven and the sunken pad can take down or pull on pipes and lines in its path.

There are pre-fab concrete pads available, but some argue it is better to pour the concrete pad on site if you are going to use concrete at all. Constructing the pad requires building a frame, base, reinforcements, and pouring the concrete, but this can be well worth the effort. The more level and custom to the soil beneath the concrete slab is made, the better it can support the unit and the less it will sink over time. Pouring can lessen the chances of cracking due to stress or exposure to the elements.

While many HVAC old-timers stand by concrete as the best option, whether it be pre-fab or poured, it can have costly consequences in the long run if it does sink. Also, it is harder to replace cracked or damaged concrete pads than a plastic one.

While plastic sounds like a cheaper, flimsier alternative to some, the material is actually much better equipped to absorb the vibrations from the unit. A pad may be made out of plastic, rubber, or recycled materials. A more pliable surface can last just as long as any concrete slab if installed properly. Newer air condenser units are becoming lighter all the time, making concrete a more obsolete choice.

What to Look For in a Pre-Fab Pad  

Before purchasing a pre-fab pad, it is important to buy one that will meet your location and air conditioning condenser’s specific needs. Here are some factors you should consider before purchasing an AC condenser pad:

Zoning and Size

Before installing a pre-fab pad, be sure to check your town or city’s zoning codes. Some cities require you to have a 3” pad at minimum no matter the size of your unit.

There will also be rules and regulations that pertain to where the unit can be placed in relation to the house in the yard. Placement and size of your pad may not be up to you; it may be regulated by your local zoning boards.  

UV-Resistant and Waterproof

It is important to keep in mind the different weather your pad will experience year-round before purchasing a condenser pad. Your pad should be UV-resistant and waterproof. No matter where you live the pad will be exposed to the sun’s UV rays for prolonged periods of time. UV rays can cause cracking and can be very hard on a regular plastic pad without protection. Any pad that is UV-resistant will additionally be waterproof.


What makes a pad durable? Look for a pad with ribbed surfaces to distribute weight evenly and help absorb the vibrations from the unit. Pads made from recycled plastic are not only UV resistant, but also won’t crack from too much rain exposure.  

Plan for Proper Installation

No matter how great the pad you purchase might be, if it is installed incorrectly its functions can become moot. It is best to hire a professional to come install the pad properly to ensure that the unit is level and secure. A professional will also be familiar with local zoning laws and make sure everything is up to code.

People Also Ask

When it comes to AC condenser pads, people often tend to have a lot of questions as it does serve a very important purpose. Thus, we took your most frequently asked questions and answered them in the hope of clearing any confusion you may have. Let’s take a look at them:

What is a Condenser Pad?

The major purpose of a condenser pad is to provide stability to your air conditioning unit. It keeps your central AC unit in place securely despite all the vibrations coming from a running unit. If the condenser pad is properly placed and fitted, it can help extend the life of your AC.

How to Size an Air Conditioner Condenser Pad?

The sizing of the compressor pad plays an important role. When looking for one, make sure it’s big enough so that the compressor supports are away from the parameter.

Why Strap Down Condenser Pad?

Strapping down the condenser pad can be an additional step to ensure it remains secured in place. This is because, at times, the internal vibrations or perhaps earthquakes can set it loose. Furthermore, this is often mentioned in the instructional manuals of the products.

Does AC Condenser Need to Be Level?

It is absolutely crucial to have a leveled condenser, and one of the most important reasons why that is the case is because if the AC condenser is not leveled, it can affect oil levels inside and lead to the compressor’s motor not being lubricated. This can ultimately lead to an overheated or inefficient unit.  

Where to Set Pad For Ac Condenser?

The pad should be located in close proximity to the house so necessary hookups can be made. This is a very important factor to consider which, if not looked into, can be rather inconvenient.

How Do You Level an Ac Condenser Pad?

It is crucial to level your AC condenser pad as you can have problems with your fan blade or compressor oil if the unit is not leveled. If your unit is unlevelled, dig out a bit of dirt from underneath the unit from the side, which has sunk down. You can then use the same dirt underneath it to prop your unit up, which then makes it level. You can use a level device to check if the product is now leveled.
