Professional Carbon Monoxide Testing in Yakima

Accurate Testing with Fast, Reliable Results

CO is odorless, colorless, and potentially deadly. Our licensed technicians use advanced detection tools to accurately assess carbon monoxide levels in your home. We test around fuel-burning appliances, HVAC systems, water heaters, and fireplaces—common sources of CO exposure.

If we detect elevated levels, we respond quickly with clear recommendations and actionable solutions. Whether it’s poor ventilation, a failing furnace, or a cracked heat exchanger, we’ll explain the issue in plain terms and help you resolve it.

Protect your family from invisible dangers with professional CO testing.

When to Schedule Carbon Monoxide Testing

We recommend scheduling carbon monoxide testing at least once a year, ideally before the start of the winter season when heating systems are used most heavily. This proactive approach helps ensure that your fuel-burning appliances are operating safely and efficiently. In addition to annual checks, carbon monoxide testing is strongly advised if you’ve recently installed any new fuel-burning appliances or home heating equipment. Other warning signs that signal a need for immediate testing include symptoms like persistent headaches, dizziness, or nausea that seem to occur indoors. If your carbon monoxide detector has gone off or shows signs of malfunction, or if your furnace, water heater, or gas appliances are aging and have not been recently maintained, a professional inspection is essential.

Our team offers free second opinions and will gladly evaluate your HVAC system during the same visit to confirm that everything is functioning safely and up to code.

Don’t wait for symptoms to appear—get peace of mind with proactive testing.
