Resideo Opiniones 

Wait until 10 am EST to get support for a thermostat app that does not work? Ridiculous. Honeywell should demand better of third party app makers. A simple scheduling task does not work so the system wastes energy and time in the meanwhile.

Customer service leftme Probably the worst customer service I’ve ever experienced.
The representative sounded annoyed from the start and had no interest in helping. I was simply asking how often the thermostat’s ambient temperature sensor updates, as the display seemed stuck for hours. Instead of answering, she sighed and kept repeating, “If you’re not happy, return it to the merchant.”
She refused to explain or offer any technical advice, not even a suggestion for reset or calibration. Her tone was unpleasant and dismissive — it felt like she just wanted to hang up.
This wasn’t technical support at all. I left the call feeling frustrated and disrespected. I wasn’t asking for a refund, just a clear answer — and got none..

Vriendelijk geholpen door support en probleem opgelost met Honeywell Lyric T6.

Always was happy with my Resideo T6 thermostat.
But then the T6s were made obsolete bij Resideo without letting customers know.

I was struggling to set everything up again, even with help from the Q&A on their own site and nowhere did they share this information.

It' s bad enough to do this, but not sharing the information with your customers makes it so, I will never buy anything from this fraudulent feeling company again.

Le modèle T6r vendu comme le plus efficace, et bien écran à cristaux liquides HS après 4 ans pour ainsi dire sans utilisation du tactile car utilisation de l’application, bug de celui ci et comme plus d’accès à l’écran et bien il est HS car oui Resideo ne dispose pas de pièce détaché ou de réseau de réparation. Et non vous ne rêvez pas éviter la marque sauf si vous voulez du utiliser à jeter, mais à 250 euros le thermostat…. Vous trouverez moins cher pour aussi bien

Wanted to put a brand new C1 to use I bought several years ago as spare.
Can’t connect it because according to Resideo the firmware is too old. And it can’t update if it can’t connect.
They told me to trash it and buy something new.
Disgusting! 🤮

The device did not last 10 years, customer support absolutely crap, wasting your time. Please see below.

Could you please confirm whether the issue also occurs when the device is in normal mode and located outside your home?

Additionally, kindly ensure that the battery has been inserted correctly. To help us better understand the situation, we would appreciate it if you could send us a short video demonstrating the issue.

If I could give zero stars I would. Don’t buy this product. There is no customer service. The phone number provided Doesnt work and they insist it does. It take about two days for them to answer emails and then they just ask patronising questions. If I had known this beforehand I would never have bought this system. Please don’t buy this system. It’s expensive and you have no product support available. It’s a complete con job

My Honeywell central heating programmer has never worked as it should despite my plumber and I following the printed instructions to the letter.

Today I spent an hour trying to find a telephone number for Honeywell UK Technical Support that answered - there a several on the internet - none of them worked (not even the American and Canadian ones!).

I did find the Support page on Resideo's UK website but it has no technical support contact phone number, just a chat page that doesn't work and an enquiry form which is totally unsuitable for a discussion about complex technical issue.

My brand new Honeywell Central Heating Programmer is going in the bin and I will never buy a Honeywell product again.

Contacted support to find out how to get replacement faceplates for my Evohome controllers. Originals have gone an awful yellow colour but replacements are discontinued. Support told me to “try the internet”. When I explained I had, and that all retailers say these parts are discontinued, my case was closed with no further explanation. The controllers are still an active product, which means the faceplates must also be manufactured. Resideo don’t care though. They are the worst thing that ever happened to Honeywell

I am trying to get a RMA number, for a smoke detector. They sent me a device with a bad MAC address. I cannot register the product in set up process. Resideo will not issue a RMA. This is the worst customer service experience I have ever had with a company.

Residio refuses to reimburse us for labor charges in the amount of about $1,800 for replacing 3 defective whole house dehumidifiers. The 3 units failed within the last 4 years! Each time we incur over $500 in diagnostic and replacement labor charges. The humistat is defective in each unit! Be aware of buying any unit with a Honeywell labor as the warranty is via Residio.

Well it took a few emails / quite a few to get our First Alert smoke detectors replaced under the 10 year warranty . Our contact was Connie who followed through till the 3 First Alert Smoke Detectors delivered on 6/05/25.
Connie was a good example of what customer service should be her follow through once involved was reassuring.
When you have a product that is installed in most new homes under the building code, a product that saves life's this company honored their warranty.
Thank you Connie and all those involved in replacing our First Alert Smoke Detectors.

called First Alert due to a malfunctioning smoke/CO2 detector. Juan, the first rep I spoke with, was a bit tough on the phone. He agreed to send me a replacement,and I had to pay shipping cost of $6.50 or so. I did pay the shipping cost via the link he sent me. He and the company never sent me a shipping notification with UPS tracking number, so I can keep an eye on this shipment. I waited for a couple of weeks and called back this company -Resideo/First Alert. Spoke with Gustavo, and then asked to speak with the supervisor (Edgar). Very tough conversation. Both of them told me that the replacement was delivered on May 5, 2025 ( a week ago), however I never received this shipment. I asked the supervisor why I wasn't notified of the shipment notification, and he said he needs to do investigation that would take a lot of time, and the do re- training of staff. I asked to send me another fire alarm detector replacement, and he told me " do you think we will be sending you replacement every time you want"?, and also told me to contact UPS. Very bad attitude and bad customer service. What am I supposed to do now, because this company doesn't notify customers of the shipment and shipment tracking number???

Contacted support for our C1 camera, because I couldn’t connect to it anymore. After receiving support mails now and then for about a month, the conclusion is the firmware isn’t supported anymore and you can’t use the camera anymore.

Never had such bad product support that after only 5 years a product is unusable. I have a 15 year old webcam that still works like a charm. Nevermind the fact that while the camera was still “supported” it didn’t work half the time…

I would advise people to look at other brands when considering this type of product. And Resideo, please… Get your sh** together and make sure you give a decent product lifetime.

I moved in to my home nearly 3 years ago and was just baffled and could not get the app on my phone for the Honeywell thermostat. I was so frustrated and thinking I would just have to buy another one as it was already registered. After emailing thinking this is the last resort and thinking no one would really help I was promptly contacted by Angela!! I can not believe how I had left it for so long this was resolved within 2 days only because of me though as I was giving wrong info!! (Ref 15132236)Please please please do not ignore and not pass this message on. We are unfortunately in a stage in the world where people will not help unless you pay but you have restored my faith in the world. Didn’t need to pay. And Angela is an absolute credit and asset to you. Thank you again! Am so grateful!

I'm surprised by the Customer Service I received from Resideo. I didn't even purchase anything from them.
I moved into a house with Honeywell Thermostats that are confusing to program. I got so desperate, I emailed Honeywell UK Customer Service and ended up being answered quite quickly by 'Micheal'.
Solved the problem in one email for someone who was never technically a customer...Nice!
Case reference number is 14929956.

I had to contact Resideo (uk) re my Honeywell Evo Home Heating system support - which is provided by Resideo. All I can say is that they were excellent, even after 4 years of owning the product the support was some of the best I have ever received for any product. Fantastic product knowledge and technical expertise. Thank you Resideo, but specifically thank you to Steve in the UK Evo Home technical support.
