The Best AC Condenser Pads: 2019 Buyers Guide

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.

Durability

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.

Reviews of the Best Air Conditioner Condenser Pads

There’s not a whole lot of variety in pads. Let’s just take a quick look at a couple so you have an idea of sizes and what they’re like.

PROS

  • Versatile
  • Will Not Deteriorate Over Time
  • Able to Weather the Elements Easily
  • Lightweight, Despite Being Super Strong
  • Diversitech Provides Good Customer Service

CONS

  • Not the Greatest Aesthetic

Our Review

The Diversitech EL3636 E-Lite is an excellent AC pad that will be able to handle anything you throw at it. It is made of some of the thickest, most heavy-duty, solid material you will be able to find – it is a full three inches thick, in case you are doubting its capabilities.

It will be able to easily hold units of up to 250 pounds, which makes this pad quite versatile. Yes, it can be used for air conditioners, but it can also easily be used for generators, pool heaters, garden composters, rain barrels, and pretty much anything you could ever need a pad for.

It also comes with lots of bracing, which is ideal for those who live in especially windy areas, or areas of the country that are prone to tornados or strong hurricanes. All in all, this pad is incredibly tough. You will not be able to go wrong with the Diversitech EL3636-3 E-Lite.

Bottom Line

The Diversitech EL3636-3 E-Lite is a top-notch AC pad that will last you for years and years and not deteriorate, even with the heaviest air conditioning unit possible pressing down on it. The only thing to consider is that it is not the most attractive pad out there – users report it is a rather ugly pale grey color.    

PROS

  • Durable
  • Great Value
  • Can be Easily Removed
  • Feels as Solid as Concrete
  • Awesome for Mini-Split Air Conditioners Up to 18,000 BTUs

CONS

  • Does Not Come With Great Instructions
  • Condensation Easily Discolors the Platform

Our Review

The Ideal Air 728184 2 x 16 x 36 Cement Equipment Pad is a great AC pad if you are not interested in investing in real concrete. This item is made of a styrofoam base with a concrete cover, making it much more lightweight (it only weighs about ten pounds in total) and easier to move around than some of its more solid counterparts.

For AC units, you typically will not need a pad that is sturdier or made of higher levels of concrete, so you are not missing out on anything when you order this pad. And do not think that just because it has a styrofoam base it is somehow less tough or less able to withstand any adverse weather events – this pad will definitely be able to ride out even the toughest storms.

All in all, when you are talking about bang for your buck or even the pure convenience factor of being able to easily move this pad around in case you move or need to otherwise relocate your mini-split air conditioner – you will not be able to find something that works better for you than the Ideal Air 728184 2 x 16 x 36 Cement Equipment Pad.

Bottom Line

The Ideal Wir 728184 2 x 16 x 36 Cement Equipment Pad is an excellent AC pad that is lightweight and easily moved around but will still provide high-quality support. It may not be the most aesthetically pleasing after a while, though, as condensation will produce discoloration.

PROS

  •  Durable
  • Lightweight
  • Three Inches Thick
  • Can Hold up to 200 Pounds
  •  Textured Surface Prevents Slipping

CONS

  • Is Advertised as 36 Inches by 36 Inches But is Actually Smaller Than That

Our Review

The DiversiTech ACP36363 The Black Pad is a versatile little AC pad that can be used for a wide variety of different uses. Users report that this pad works great to hold different pieces of equipment, including a mini-split air conditioner, a generator, a pool heater, a pool pump, a mineral dispenser, and a washer/dryer – but also that it can be used to provide a boost to enter into a bathtub for elderly folks, or even as a dog bed that is completely resistant to chewing! And when we say completely resistant, we mean it – this pad is three inches thick and made of a specially concocted mixture of plastic and rubber.

And as a bonus, the rubber is recycled, meaning that when you purchase this pad, you are doing Mother Earth a service. But although it is thick and hefty, it is also quite easy to drill through this pad so that you can attach equipment to it or secure the pad into the ground. There is not much to dislike about the DiversiTech Black Pad!

Bottom Line

The DiversiTech ACP36363 The Black Pad is a great AC pad that is versatile and made of recycled material. The only consideration to make is that it is actually slightly smaller than advertised.  

PROS

  • USA made
  • Lightweight, flexible and durable
  • Made from 2 inches of UV resistant plastic
  • Textured with ribbing to ensure level platform for the unit
  • Able to support a condenser filled with water weighing over 200 lbs
  • This unit pad is self-leveling ground support without inserts for easy installation

CONS

  • Some might find this pad too thin for the weight of their condenser. However, in the vast majority of cases, its size does not compromise the integrity of the pad

Our Review

This plastic platform offers self-leveling ground support that doesn’t require inserts. It is a great valued platform for your air conditioning condenser as it is easy to install. It’s made of UV-resistant plastic. Be sure to check your local zoning laws before purchasing.

​Conclusion

Whether you use concrete pre-fab, pour your own concrete, or purchase a plastic pad for your AC condenser unit, the most important thing is to keep the unit dry and level. Talk to an HVAC professional to see what pad will work best with your unit, property, and climate.

As units are manufactured to be lighter and pads are better engineered to absorb vibrations, ordering a condenser pad online becomes a more viable and affordable option for homeowners.
