Better Warranty
Set name: 18,000 BTU - 230V / 20 SEER2 This was a replacement condenser unit due to compressor failure. I’m a 80 year old retired Real Estate Broker/ landlord. I maintained over 100 rentals along with sales. For forty of those years I installed, and serviced all the heating, cooling, & electrical and was licensed to do so. After I retired I still had a few rental i kept. My last purchase was a replacement condenser from Della for a couple years old unit. I have purchased and installed 15 mini splits in my properties, 8 of which were Della. I have had two failures, one was inside unit had a coil leak and the second was compressor failure, both were Della units, both were refused coverage under warranty. That amounts to a 25% failure rate and 100% warranty refusal. All my other brand units vary from 4 years to 7 years and no failures. Della’s are 1 to 4 year. Due to no warranty backing and most brands are made by the same Chinese manufacturer I will be discontinuing using Della and buy only the cheapest units. And should I have future failures I can purchase a complete new unit for the price of Della replacement parts. I think that this would be a better warranty. But the good side is did like the units and the parts service was great, just expect to pay, don’t expect any guarantee.

Thank you for taking the time to share such detailed feedback, we’re also glad to hear that you’ve generally been happy with the performance of our units and our parts service. We’re sorry to hear about the warranty experiences you had with your previous units. To clarify, our standard warranty provides coverage for one year, and when a covered issue is confirmed to be a manufacturing defect within the applicable warranty period, it is not simply denied without review. At this time, we also offer a Lifetime Warranty with product registration, subject to the applicable warranty terms. We understand that your experience has shaped your decision, and we respect your feedback. We’ll certainly take your comments back to our team as we continue working to improve both our products and customer service.
