Great customer service

After several issues with delivery I called Della customer service for assistance. Lizzy took time to listen to my situation and escalated the problem to her supervisor. She promptly called me back with a solution to the problem.

Reply from Della

Dear customer, thank you for sharing your experience. We’re glad to hear that everything else worked great, but we’re truly sorry to hear about the flare fitting failure and the inconvenience caused by the refrigerant loss and repair. We understand how frustrating it must have been to have to hire an AC company to get the issue resolved.

We take product quality seriously and appreciate you bringing this to our attention. We’d be happy to look into the issue further and see if there’s anything we can do to assist. Please feel free to contact our customer service team with your order information and any details about the repair.

We sincerely apologize for the inconvenience and appreciate your feedback. It helps us identify areas where we can improve.

Outstanding product and even better support

I couldn’t be happier with both the product and the company behind it. The build quality is top-notch, and doing the installation myself ended up being significantly smoother and less challenging than I had anticipated.

What really sets them apart, though, is the customer service. I called in with a specific situation regarding my order, and the representative on the phone went well above and beyond what I expected to help me sort it out. It’s rare to find a team that genuinely listens and works with you like that. Excellent products backed by an exceptional team—highly recommended!

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.

Portable air conditioner not cooling

The company was very helpful with troubleshooting and tracking the problem with the unit, which no longer cools or generates condensation. The unit is just over one year old and has only been used a a dozen times. Rebooting the unit did not fix the problem.

Delta heater air conditioner

My Della heater air conditioner quit working and it's 2 months out of warranty . I really appreciate that Della was willing to help me out despite being outside the warranty. I really recommend this company and appreciate Lizzy helping me with this process.
