In most homes, air and ducts are shared by multiple appliances.<\/p>\n<p>In homes with central HVAC, the AC and gas furnace use the same ducts. When a problem occurs, the people frequently blame the AC even though the real problem is typically caused by the stove or another fuel-burning appliance. This can create confusion.<\/p>\n<p>One more reason is that online articles frequently mix up heating, ventilation and air conditioning. Various people use the word \u201cHVAC\u201d for everything which makes people think the entire system is dangerous. Some assume that because the AC is part of the central HVAC system then it might produce unsafe gas. But, only appliances that burn fuel such as furnaces or water heaters can produce carbon monoxide.<\/p>\n<p>Sometimes, carbon monoxide alarms go off while the AC is running. This can make it appear that the AC is causing the alarm, even though it is only moving air in the home. Some people also think that because the AC is connected to the house or outside then it must make gas.<\/p>\n<p>The truth is, air conditioners do not burn fuel and do not produce carbon monoxide. It\u2019s easy to get confused, but the AC is never the source of this unsafe gas. If you\u2019re concerned about your air conditioning system\u2019s performance or need professional assistance, consider\u00a0<a class=\"decorated-link\" href=\"https:\/\/menatworkacrepair.com\/ac-repair-new-orleans\/\" target=\"_new\" rel=\"noopener\" data-start=\"1562\" data-end=\"1646\">AC repair in New Orleans, LA<\/a>\u00a0to ensure your system is working properly and safely.<\/p>\n<h2 id=\"what-actually-produces-carbon-monoxide-in-a-home\" class=\"joli-heading jtoc-heading\"><strong>What Actually Produces Carbon Monoxide in a Home?<\/strong><\/h2>\n<p>Carbon monoxide (CO) is an unsafe gas. It comes from burning fuel but not from your air conditioner. Any appliance that uses fire or burns fuel can create CO if it is broken or not working correctly.<\/p>\n<h3 id=\"common-sources-of-carbon-monoxide-in-homes-are\" class=\"joli-heading jtoc-heading\"><strong>Common sources of carbon monoxide in homes are:<\/strong><\/h3>\n<ul>\n<li>Gas furnaces<\/li>\n<li>Boilers<\/li>\n<li>Gas water heaters<\/li>\n<li>Gas stoves or ovens<\/li>\n<li>Fireplaces<\/li>\n<li>Cars running in attached garages<\/li>\n<\/ul>\n<p>These devices require the proper ventilation to safely vent gases.

An air conditioner only moves air in your home. It doesn\u2019t make carbon monoxide. Sometimes, it might look like the AC is causing the problem particularly if an alarm goes off while it is running. But typically, the real source is another appliance that uses fuel like a gas furnace or water heater.<\/p>\n<p>In homes with shared ducts, an AC can move air that previously has carbon monoxide from other appliances. The AC doesn\u2019t make the gas but it just spreads it around. This can create it to look like the AC is the problem but it\u2019s only moving the air.<\/p>\n<p>Running an AC slightly changes the air pressure. This can make gases from furnaces or water heaters flow back inside. Blocked vents, poor airflow, or broken fuel appliances can allow carbon monoxide to build up. The AC may spread it more, but it never makes it.

It\u2019s easy to think the AC is the problem but that is typically not correct. Most of the time, something else in the house is causing the alarm.

ACs cool your home by moving heat outside so they are safe and do not produce harmful gases. Sometimes, the people are concerned when a carbon monoxide alarm goes off while the AC is running but that does not mean the AC is the cause. The carbon monoxide typically comes from sources such as gas stoves, water heaters, furnaces, fireplaces or cars. In some cases, an AC can move air that previously contained carbon monoxide from another source which can make it appear the AC is involved.<\/p>\n<p>The essential things are to keep all fuel-burning appliances in good condition or have working carbon monoxide detectors and stay cautious.
