ArmorPad™, High-Strength & Light-Weight

ArmorPad’s light weight requires only one installer to transport; durable polymer shell resists UV, cracking, crumbling and spalling of its cementitious competition.


The ArmorPad is constructed of a dense foam core base enveloped in a shell of durable polymer on five sides that aesthetically simulates the texture and color of gray concrete. The entire product line of 24, 30, 32, 36, and 40-inch-square (61, 76, 81, 91, 101-cm2) x 3-inch-high (7.6-cm) models saves jobsite costs, because only one person is needed to transport and install it. For example, a 36-inch-square x 3-inch-high ArmorPad weighs only 8-pounds (3.6-kg) versus competing foam core pads with cementitious shells weighing 35-pounds (15.8-kg), or solid concrete pads weighing more than 300-pounds (136-kg).

ArmorPads also surpass the competition in durability tests, which prove the weight of a truck driving over it can’t crush it, drilling into it can’t crumble or crack the polymer shell, landscaping implements can’t spall the surface, and equipment weight of even the largest of residential condensers can’t indent or depress it.

The ArmorPad polymer shell is not sprayed on, but rather molded into a one-piece, strong and durable extrusion that’s compliant with ASTM D-2299 standard “Recommended Practice for Determining Relative Stain Resistance of Plastics.” The polymer surface perpetuates a brand new appearance, because of its built-in resistance to UV degradation, coil cleaning chemicals, landscaping chemicals, weather and canine urine.

The ArmorPads also boast the industry’s most dense foam core, which minimizes permanent compression damage and holds anchors securely. The foam core bottom also features a unique foil-backing that resists moisture and an embedded chemical repellent that deters burrowing animals and insects.

Other ArmorPad features include:

  • Design and performance-tested in the field with contractor focus groups;
  • Designed for 90-percent of the industry’s condenser sizes of up to five-ton systems. Additional size introductions are planned in the future;
  • Ideal for retrofits where larger, more efficient condenser replacements require a larger or new equipment mounting pad;
  • Can be secured onto and cantilevered out over smaller unsightly, but structurally-sound existing pads during retrofits;
  • Easily accepts and securely holds drilled-in hurricane clip anchors in high wind zones;
  • Available through most traditional wholesale HVAC/R distributors.

RectorSeal® Introduces the PRO-Fit™ Precision Swage Kit, the Next Generation in Copper Pipe Swage Tools

PRO-Fit™ Precision Swage Kit is a six drill bit swage set for quickly, easily and inexpensively swaging refrigeration tubing without leak-prone imperfections.

RectorSeal®, Houston, a leading manufacturer of quality HVAC/R tools and accessories, introduces the PRO-Fit Precision Swage Kit, a collection of six drill bit swage tool sizes designed for quickly, reliably and inexpensively swaging copper and aluminum tubing used in split-system air conditioning, refrigeration and plumbing work.

PRO-Fit Precision Swage Kit bits used with a (minimum) 12v, 2,000-Plus RPM drill or impact driver combine friction, heat and pressure to reform tubing into a perfect swage for joining two similar-sized tubes, especially for use with any mini-split, VRF or split system unitary equipment installation. The five-second process eliminates copper coupling expense, cuts brazing by half and produces a more consistent swage than laborious manual hammer/punch swage tool methods. It’s also 12 times faster, less expensive and requires no maintenance versus hydraulic hand-swaging tools. PRO-Fit swages help prevent the potential sidewall splits, over-swaging and leaks associated with traditional methods that can raise installation costs and damage the environment.

“Furnace freezing up! Please help!”

furnace“Hi guys!

So, like I mentioned, during very cold weather my furnace wont start. I was getting a pressure switch error code, that led me to find a frozen condensate line. I cleared the obstruction and then it worked ok. Now when its cold out it still wont start, giving me the same error code. I checked for another frozen hose but I didn’t find any.

I’ve set up a heater in front of the furnace and if I turn it on and wait about a minute the furnace will kick on and it will run fine as long as that heater is on. Keep in mind that I cant find any frozen spots in the line before I start the heater.

The stress of this is keeping me up at night wondering if the furnace is running or if its kicked off! haha, I could really use some advice. I’m an electrician by trade so I have an understanding of how the whole system works.

Some guys at work were suggesting that maybe wind was being forced in the cold air intake from the outside and it was freezing it up. Not really sure, I would appreciate any advice!

Thanks! – kgray33″

Trap is probably frozen. Buy some electric heat tape and wrap the condensate trap along with the lines. That furnace should never have been installed where it can freeze up like that. – PeppyEpi

Best location to place an air filter?

Q: There are two possible locations to put an air filter for my HVAC system. 1. ceiling return grill 2. furnace blower unit in the attic

Currently there is no filter at the blower unit. I have been putting Filtrete 1900 at the return grill because it’s easier to change and I assume that will keep the return duct cleaner.

Recently a HVAC guy commented I will have better filtration if the filter is closer to the blower (he suggested #2 location)

  1. Can I put two filters in my system – one at the return gill (a cheap one) and one at the blower (Filtrete 1900)? or that will create too much airflow restriction?
  2. If I should only have one filter, which location will be best? – indhtgc

A: I would keep the filter where it is. In my experience, filters that are installed directly at the unit or even inside the unit can be a pain to replace. The return air filter grille is much more convenient.

And no you don’t want to double filter it. That just puts unnecessary stress on the motor because it has to work harder to overcome two different filters instead of one. – Cobra449
