CO Alarm Installation in Denver, CO : Jim Needham Heating, Cooling, Plumbing, Drain & Electrical

Carbon monoxide is invisible and odorless, which is why proper detection matters. At Jim Needham Heating, Cooling, Plumbing, Drain & Electrical, we install CO alarms in the right places with expert wiring and secure mounting, so you never have to question whether your home is protected. Our electricians understand current code requirements and layout best practices—and we always put safety first.

If your home lacks carbon monoxide protection or the existing units are outdated, we’ll help you upgrade quickly and cleanly. Every installation and repair is tested and verified for function, placement, and backup. These are essential systems you want to get right the first time, and we can help you do just that.

Where Should Carbon Monoxide Alarms Be Installed for Maximum Protection?

To provide full coverage, these devices need to be installed in precise locations—not just placed wherever there’s room. CO is lighter than air and moves differently than smoke, so strategic positioning makes a big difference in how quickly you’re alerted. We take layout, equipment, and home size into account when planning each installation.

Common areas where CO units should be installed:

Outside each sleeping area to ensure everyone hears the alert at night

On every level of the home, including finished basements

Near attached garages to detect car exhaust seepage

In rooms with fuel-burning appliances like gas furnaces, water heaters, or stoves

Near fireplaces or wood-burning stoves that can release CO over time

In bonus rooms or converted spaces that may lack ventilation or proper equipment clearance

Proper spacing and interconnection allow the entire household to respond quickly in the event of elevated levels. We install each system with careful attention to both code compliance and real-life usability.

What’s the difference between a CO alarm and a smoke detector?

A CO alarm detects carbon monoxide—a gas you can’t see or smell—while a smoke detector responds to visible particles in the air. They serve different purposes but are equally essential. Many homeowners now opt for combination units, but placement and function still differ. We’ll help you choose the right devices for each area of your home.

Do I need more than one?

Yes—one device alone won’t protect your entire home. CO can build up in specific areas depending on how your appliances are vented and where people sleep. Modern codes typically require at least one on every level and near sleeping areas. We evaluate your space to ensure complete coverage without over-installing.

How do I know if my alarm is working properly?

Most have a test button that should be pressed regularly to confirm the alert sounds correctly. We also recommend checking the expiration date printed on the back or side of the device. If the unit is more than 5 to 7 years old, it may no longer detect gas accurately. Our team can test and replace units as needed.
