Kidde Fire SafetyReviews of kidde.com

Consumer reviews and forum discussions highlight several recurring issues with Kidde CO detectors:Frequent False Alarms: Users heavily report interconnected systems and stand-alone CO/smoke detectors going off in the middle of the night despite no smoke, fire, or detectable CO present.Premature Failure: Despite marketing a 10-year lifespan, many detectors begin showing "end of life" errors (e.g., chirping twice every 30 seconds) or battery faults within 3 to 5 years.Customer Service: Buyers consistently cite poor experiences with support, including extremely long hold times, unreturned emails, and delayed delivery of warranty replacement units.General Brand Consensus: Due to these persistent issues, many users in forums like Reddit advise switching to alternative brands known for greater reliability, such as First Alert or BRK.

What a shower of s…. Do not buy this brand, if you have ant issues it’s like contacting another planet. Why do companies like this hide behind contact form, give people a phone number. Absolutely disgusting company.

These alarms used to be great until Kiddie took over. I bought a four pack of smoke alarms and 3 out of 4 beep all the time. They are brand new and have new batteries as well as have been cleaned multiple times and still beep all the time. One of them won't stop at all and we cant even use it. Over $100.00 and don't work for crap. Nice😡

My alarm is malfunctioning. The company confirmed it is defective and said they would send a replacement in 7-10 business days via FedEx. After 14 business days and no replacement I called again. I was told the replacement is on back order and they do not know when it will arrive. You wait on the phone for 30 minutes for Customer Service to answer. Kidde makes DEFECTIVE safety products and there is no urgency from the company to replace a defective product!

I purchased a Kidde P4010ACSCO hardwired smoke and carbon monoxide alarm with a 10-year sealed battery from Home Depot in April 2022 for about $79. In June 2026, the alarm began going into false alarm mode approximately every 154 minutes, making it completely unreliable. What has been even more disappointing than the product itself is Kidde's customer service. Home Depot directed me to the manufacturer because the unit is covered by a 10-year warranty. After three emails, one phone call, and an online chat, I still have no replacement and no meaningful resolution. A smoke detector is a life safety device. If it constantly false alarms, people begin to ignore it or disconnect it, defeating its entire purpose. Based on my experience, I cannot recommend this product or Kidde's warranty support. I expected a 10-year alarm to last much longer than four years and for the manufacturer to stand behind its warranty. Instead, I'm left with a $79 alarm that is unusable and a company that has not honored my expectations for customer service. I will not be purchasing Kidde products again.

Do not buy this brand! They are nearly impossible to contact. Non existent customer service. When calling expect to get an extremely long wait. They do not respond to emails which leads me to believe all customers are having problems. Go for another brand.

Wired smoke detectors that are supposed to last 10 years have failed three times so far in ten years. So basically at least every couple years they fail extraordinarily LOUDLY, screaming Fire and beeping at 3am, waking everyone up like a brutal torture device. I have to climb on chairs and spray them with compressed air and then a few nights later it starts all over again. I don’t think they care about this. They just send more crap units. They are sensitive to dust and spiders so i spray them regualary and they still fail, screaming in the night. I hate them. Now they are sending new units and saying i have to go buy adapters for the wiring harnesses!! They refuse to supply new adapters!!

I would have given "0" if possible. We bought 9 Kidde alarms which have a ten year life. After about 4 years over a period of months every alarm failed. In most cases this was in the middle of the night waking up us and the kids. Then we need to go through the process of identifying the malfunctioning unit as the units are hard wired together and you cannot tell which unit is going off. When we called the company, after waiting for over a half hour - it was suggested that the failure was due to our maintenance and also that we needed to prove the units were malfunctioning as they "could not just take our word for it"! Absolutely crazy customer service - completely unhelpful. We will get unit somewhere else - I am surprised and disappointed that Home Depot sells this junk.
