Carbon monoxide is colorless, odorless, and deadly. Our Dallas team provides thorough carbon monoxide testing to make sure your heating system isn't putting your family at risk.
Every heating season, we test hundreds of furnaces across DFW for carbon monoxide leaks. It's one of the most important safety checks we do, and we take it seriously. Even small amounts of CO can cause health problems, and high levels can be fatal.
We use professional-grade detection equipment to check for carbon monoxide around your furnace, in your ductwork, and throughout your home. If we find any issues, we'll identify the source and fix it immediately. Your family's safety isn't something we compromise on.
When to Get CO Testing
Start of every heating season before you rely on your furnace for warmth. After any furnace repair, especially work involving the burner or heat exchanger. If you notice headaches, dizziness, or flu-like symptoms that improve when you leave the house. Before buying or selling a home to ensure the heating system is safe. If your CO detector has gone off, even if it stopped alarming—this requires immediate professional testing.

Such a great company! Quincy was extremely professional and efficient. The technician was knowledgeable and helpful explaining everything that was being done or needed to be repaired to help me understand versus just trying to send me an estimate. I highly recommend Quincy, Hayden, Jake or Ron for any HVAC needs. Thank you, Quincy again for being so amazing!

Great company to get your air conditioning done by. They were the lowest quote out of the 3 companies I had come out. The guys came out and put in a new furnace, coil, plenums, and condenser. American standard was the brand and it looks great. Ron Sanford was very professional and made sure everything was right and working before they were done.
