Residential Smoke Alarm Testing & Inspections

Residential Smoke Detector Services

Smoke alarms and carbon monoxide detectors are typically among some of the most ignored devices in a home. However, they are your family and your home’s best investment when it comes to saving lives and property.

Fires are somewhat common, and it’s critical to have fully functioning and well-maintained fire alarms throughout your residence to detect the first signs of a fire.

It is recommended that smoke alarms are placed on every level of the home and inside and outside every sleeping area.

Carbon Monoxide Detectors

Carbon monoxide can cause illness or even death. In fact, of all the poisoning deaths in the US, carbon monoxide is among the most common.

If left undetected, this colorless, odorless gas can kill an entire household in hours or even minutes. With properly functioning carbon monoxide detectors in the home, these incidents are 100% preventable.

CO alarms should be installed in a central location outside each sleeping area and on each level of your home.


Certizona’s residential fire safety experts are standing by to help homeowners in the greater metro Phoenix areas keep their lifesaving devices functioning properly at all times. Whether you need alarms inspected, repaired, replaced, or are just nervous to get on a ladder and switch out your batteries, we can help!


Testing and Maintenance

Home safety alarms, including smoke detectors and carbon monoxide detectors, monitor your home twenty-four hours a day, seven days a week. They are designed to provide accurate readings throughout their lifespan.

We test and inspect carbon monoxide detectors, basic interconnected 120v residential smoke detectors with battery backup, and even smart detectors so you can rest assured that your units are always working properly. We can also clean the units and switch out batteries as needed.


Even the highest quality smoke detectors experience issues at times or stop working altogether and need to be replaced. Also, NFPA 72 requires that homeowners switch out their smoke alarms every ten years or earlier. It is also recommended by many manufacturers that CO alarms are replaced every ten years or earlier.

We can replace these devices with new, top-quality models when they have reached the end of their lifespans.

Certizona provides real quality Customer Care! They were professional, knowledgeable and safety focused! They took the time to teach us how to use an extinguisher correctly and which one is for which fire type! I feel this was SO valuable for the safely of our clients as well as our own families! Thank you for going above and beyond!

Certizona Fire & Safety provided professional service, with quality products at an exceptional price. Steve Rogers, can’t say enough about him. He is extremely helpful and knowledgeable at his craft. If you own or run a business that requires annual inspections for your fire equipment, give these guys a try … you will not be disappointed.

Steve Rogers is AWESOME!! He went above and beyond while visiting my storage site, making sure I was confident and comfortable, on how to properly use a Fire Extinguisher if ever needed. I am so grateful for him and the obvious love he has for his job.

Copperhills Church

Steve did the annual inspection of our fire extinguishers and exit lighting.  He was very thorough, professional and friendly.  We appreciate the prompt service and will definitely continue to use Certizona Fire & Safety!  Thank you!

Mikel Sitterly

We have had a few Fire and Safety companies service our fleet extinguishers over the years.  The “other guys” never seemed to have time for us and would only service a few extinguisher at a time.  Most of the time the “other guys” would tell us they couldn’t service an extinguisher and needed to sell us a new one. Certizona is just the opposite of the “other guys”.  They are on time, very responsive and very professional.  They serviced our extinguishers on site and in a timely fashion.  They didn’t ask for our first born sons, nor did they ask for an arm and a leg.  They are fair on their pricing and eager to show us how it all works.  Everything they did was transparent and honest.  I could not recommend a company more.  Look if you have Fire and or Safety needs.  Definitely give Certizona a shot.  You will not be dissapointed.

Potter’s House Apothecary

Certizona Fire and Safety has done our annual fire inspections and maintenance for the past 3 years. We are always pleased with the service and reporting they provide. Steve came out this year and went above and beyond the standard level of service expected to take care of any issues we had. I highly recommend the company.

Drew Carroll

Steve was immensely helpful. I called Certizona out to inspect and certify our fire extinguishers but Steve did much more for us! Being a pastor of a small church, I don’t really know anything about fire code and what the Marshal is looking for but Steve helped walk me through that. By the end, all our exit signs and fire extinguishers were certified and ready to go. I recommend Certizona highly!

Armando Montes

Steve was amazing! Diligent worker with attention to detail and very fast! We had Certizona install a few fire extinguisher cabinets and are very satisfied with the clean work that was done! Thank you Steve, we will be using your services in the future.
