Eg4electronics Avis 2

My EG4 DIY mini-split failed after only 5.5 months when the quick-connect fitting cracked and dumped all the refrigerant. After ~25 emails, calls, and 6 weeks of frustration, EG4 finally offered to send a line set — but never gave a date. I bought one myself from their sister company, Signature Solar, and went through the proper steps: installed, torqued fittings to spec, evacuated, nitrogen-purged, leak-tested, and recharged. The system still leaked.

I filed a warranty claim with full documentation. EG4 denied coverage, blaming “installation damage,” yet still offered a “goodwill” replacement line set. Contradictory and meaningless. If they truly believed it was my installation, why send parts? They never asked where the leak was or offered any service support to resolve it.

I reviewed their 108 Google reviews:
- 5 mention no warranty closure/support.
- 13 cite poor or no technical support, many unresolved.
Even the owner has admitted publicly that EG4 may not provide a replacement even when the issue falls under warranty. That makes their warranty worthless.

Their replies always include nice public apologies, but after a year of reviews, the same lack of support continues. Lip service only. Same old song and dance.

Bottom line: I cannot recommend EG4. If marketed for DIY installation, the fittings should be bulletproof — they are not. EG4 also struggles to support products they didn’t design in-house, and it shows. At best you’ll get apologies, at worst you’ll be left with an expensive, non-functional unit. Buyer beware.

purchased EG4 6000xp which had many small issues, contacted customer service. they asked questions about the problems, adviced on some issues but never got back with solutions on other problems, just silence. another time asked a question about warranty about 2 weeks ago still waiting for answer however first time they replied within couple of days. In addition, purchased EG4 18k, came damaged 3 times. They can't pack it wisely and put hard magnets in box where the most weight is placed while handling. tech support don't know their product well. equipment works inconsistently on some parameters. but the price compensates it. It seems they release products that are not ready for users and i will take several years to tune it. Sometimes it seems that some of their developers were drunk on a job. Retails tech support is much more accessible and willing to help but have shallow knowledge on the products.
