Understanding CO Risk

Why Annual Testing Matters More Than It Seems

CO exposure symptoms are easy to misattribute.

Protocol Focus · Why It Matters

Low-Level CO Exposure Symptoms Mimic the Flu

Headache, dizziness, and nausea from low-level carbon monoxide exposure are easily mistaken for a common illness, especially since symptoms often improve when away from the home — proper testing removes the guesswork.

Symptoms that improve when you leave the house and return when you're back are a significant warning sign.
CO detectors should be placed near sleeping areas and tested regularly, separate from professional furnace testing.
Testing takes into account the whole combustion and venting system, not just the furnace itself.

Why This Matters in Houston Specifically

Houston-Specific CO Risk Factors

INFREQUENT USE

Seasonal furnace use

Systems used only a few months a year get less natural inspection opportunity.

AGING SYSTEMS

Older gas appliances

Many Houston homes have furnaces and water heaters approaching or past typical lifespan.

DETECTOR GAPS

Inconsistent CO detector use

Not all homes maintain working CO detectors given the short heating season.

MULTIPLE APPLIANCES

Multiple gas sources

Homes with furnaces, water heaters, and gas ranges have multiple potential CO sources.

Questions

Frequently Asked Questions

How often should CO testing be done?

We recommend annual testing, ideally before the start of heating season each fall.

Do I still need this if I have a CO detector?

Yes, detectors are a good baseline safety measure, but professional testing checks the actual source components more thoroughly.

What if the test finds elevated CO levels?

We'll identify the source and explain your repair options — this typically means the furnace is taken out of service until fixed.

Can testing be done on any gas appliance?

Yes, we can test furnaces, water heaters, and other gas combustion appliances.

Is CO testing included in regular maintenance?

Yes, it's part of our standard furnace tune-up and heating system maintenance visits.
