Carbon monoxide is invisible and odorless — the only way to know your gas furnace is safe is through proper testing, not just a visual check.
Active units staged across Houston, Katy, Sugar Land & The Woodlands.
CO exposure symptoms are easy to misattribute.
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.

Many Houston homes have furnaces and water heaters approaching or past typical lifespan.
Not all homes maintain working CO detectors given the short heating season.
Homes with furnaces, water heaters, and gas ranges have multiple potential CO sources.
"AC died at 9pm in July. Tech was at our door in 30 minutes and had it running again within the hour."
"Gave us the price upfront, no surprise charges. Compressor was clearly explained before they touched it."
"Called three companies at 11pm — only one picked up. Real technician walked me through safety steps."
Carbon monoxide is colourless, odourless, and produced whenever fuel burns incompletely. In Houston homes, the gas furnace is the most common source — and the most preventable one.
The leading furnace-related CO risk. A crack lets exhaust gases mix with the air blown through your ducts and into every room of the house.
A flue blocked by a nest or debris, or damaged by rust, traps exhaust inside the home instead of venting it outside through the roof.
Burners coated in dust or rust burn unevenly and produce more carbon monoxide. Regular cleaning keeps combustion clean and complete.
Any gas appliance can produce CO. Testing covers the furnace first, but we check the water heater venting too when it shares the same space.
We test with a calibrated combustion analyser, not a handheld gadget. The analyser measures CO in the flue gas and in the air around the furnace, at the supply registers, and near the bedrooms, and the readings are written on your report.
If we find elevated CO, the furnace is shut down until the cause is fixed — there is no safe level of a cracked exchanger or a blocked flue. Most findings are small and fixable: a dirty burner, a venting issue, or a detector that needs replacing.
