The perspective of this webpage deals with HVAC central split air systems with an air handler indoors and a condensing unit out of doors connected to a distribution system of air ducts for supply and for return air. Here is an orientation around this type of HVAC system
This page is intended as a foundational resource for you to clarify your understanding of your heating and cooling system and a resource to help you make sure your HVAC system is operating effectively.

Do you have a gas furnace in your air handler? Is the air handler in the living space?
Any combustion device in your home creates carbon monoxide. If you have a furnace, your furnace is producing CO. Furnaces get extremely hot; they are combustions chambers, of course, and so they deal with heating and expansion, and cooling and contraction, and a great deal of moisture in this heating and cooling cycle. Manufacturers build really good products these days. They eliminate stress in the furnace combustion chamber as much as possible- but problems can occur, cracks can happen and CO carbon monoxide can be sucked out of the combustion chamber and right into the air plenum and right out the supply ducts. This is just the iaspect of mechanical failure creating exposure to carbon monoxide. There are many other ways to have issues with combustion gases. Make sure you see our page on combustion issues if you have a combustion device in your home. Gas ranges, gas powered cloth dryers, fireplaces … all must be assessed for possible issues..

A heating and cooling crisis is not the right t the right time to be thinking about these kinds of decisions. The issues are much wider that just picking out the new equipment. This important issues need to be addressed with careful thought. How much careful thought can you do when the air is off and you are trying to sleep and the temp outside is way too close to way too hot.
There are critical issues to understand and around which to make decisions. There is no better time than the present to start the process of understanding what makes sense and valuate where you stand now. It will pay off to be ready when the next crisis comes.
