Equipment Pad

E Liteis a plastic pad designed as a mounting base for air conditioning condensers. The rugged design provides uniform and generous ribbing for optimum, self-leveling ground support without inserts. E Lite is injection molded from polypropylene, resulting in a pad that is lightweight, but not too light. A subtle texture prevents unit slide and presents a classic appearance, which is enhanced by rounded edges and a concrete gray color. Each pad is molded with its size in raised letters.

  • High recycled plastic content
  • Subtle texture resists unit slide
  • Unaffected by UV or weather
  • Uniform ribbing transfers load evenly
  • Drillable for securing unit
  • Lightweight, yet rugged

Customers Say

Users report reliable heating in outdoor temperatures from 20°F down to -10°F, with one owner measuring a 21-degree supply-to-return temperature difference on turbo and another cutting electric bills by over 30% compared to baseboard heat. Installations are generally described as straightforward—even across three outdoor units and ten indoor heads—though some found the instructions difficult, needed an HVAC tech for charging, or added about 3/4 lb of refrigerant for long line sets.

    Purchased and installed in 2022 - worked well for 2 years besides some minor noise and leakage issues. Then main circuit board broke and was told it was apparently due to us not installing a surge protector. Service/Warranty support was responsive but it took us about 2 months to finally resolve issue and had to replace board 2-3 times, costing us a lot in HVAC tech visits and had to install window AC units (as the minisplits went out during prime summer heatwave in DC). After it was fixed, we installed a surge protector, and hasn't recurred again (although we are nervous it will). Overall, I wish I had purchased a unit that local HVAC techs could have parts for same day (instead of having to wait for a week or two for replacement control boards to be shipped across country), but purchased this unit during COVID when supplies were limited during a renovation unfortunately. I also over the past 4 years have tried over 20 times to contact support/manufacturer to get replacement air filters for the 5 mini splits and have never been able to get anyone knowledgeable and get the replacements.....so normal parts service (outside of warranty service) is just non-existent......you'll just keep getting redirected to the https://hvacdirect.com/part-quote site, but I've never received a response from that site (and its often down).......

    I got 2 wall units up and running last week and so far so good. They are keeping the main level at the desired temp in 20 degree outdoor weather. This week is supposed to get much colder so we'll see. I still have 2 more ceiling cassettes to put on this condenser, but they are going to be a lot more work.

    I have not finished the install yet, but I am very impressed with the design of the system; I really liked the attention to details in the design; the little kickstand in the air handler that holds it out from the wall while you attach the lineset. The kickstand that holds up the wiring module. The locking bar that holds up the cover. priceless! And the performance specs are awesome I think. And the condenser area seems larger than the other one I put in 5 years ago that I can't remember; probably is why it is so efficient. Not excited that the refrigerant leak sensor in the handlers have to be replaced after 15 years, but I understand that is how things are and they probably won't cost much by then.
