At Ongaro & Sons, we believe in prioritizing safety above all else. Part of that commitment means ensuring our customers across Northern California understand the immense significance of installing smoke detectors and carbon monoxide (CO) alarms.

Here’s a more in-depth look at why these devices are indispensable.

The National Fire Protection Association (NFPA) has provided eye-opening statistics that underscore the grave risks of fires. Consider the following:

  • Fire departments in the United States respond to a staggering average of 343,000 house fires annually.
  • These fires sadly result in over 2,600 civilian deaths and cause injuries to over 11,000 people every year.
  • One of the primary culprits behind these house fires? Faulty electrical equipment.

Protect Your Family and Your Home

The purpose of these alarms is simple yet crucial—to alert you to potential dangers, potentially saving your life. This is why they are intentionally loud and impossible to ignore.

It is also why our skilled electricians are meticulous in ensuring these devices not only function flawlessly but are also strategically placed for maximum effectiveness.

Smoke Detector and CO Alarm Installation, Replacement, and Upgrades

The National Safety Council (NSC) reveals that carbon monoxide, often referred to as the “silent killer,” is a colorless and odorless gas that results in over 20,000 individuals seeking emergency medical care annually.

Particularly at risk are infants, expectant mothers, and those with certain health conditions.

What are the common culprits behind CO poisoning?

  • Unvented space heaters top the list.
  • Malfunctioning furnaces, defective water heaters, and other gas appliances are not far behind.
  • Improperly installed whole-home generators can pose a CO risk.
  • Blocked chimneys, auto exhaust, and wood-burning fireplaces also play a significant role.

Unvented Space Heaters

These heaters burn fuel (like natural gas, kerosene, or propane) without venting combustion gases outside, which means CO can build up indoors if the heater isn’t getting enough fresh air.

Malfunctioning furnaces & defective water heaters

When appliances are faulty, poorly maintained, or improperly installed, they may fail to burn fuel completely. This incomplete combustion releases CO, which can then accumulate to harmful levels indoors.

Blocked chimneys, auto exhaust & wood-burning fireplaces

When chimneys are blocked by debris, nests, or structural damage, CO from burning fuel cannot escape and may backdraft into the home, posing a serious hazard.
