A central air system can run without natural gas, but when the heat needs to be turned on it won’t work. The heater side of the system requires gas to generate the flames and subsequent hot air to blow through the system. Without the gas, the system will simply blow cold or existing air without heat.
Where should a furnace be located in a house?
Typically your furnace is centrally located in the home. It is usually located in an area such as a utility closet (by a cold air return), garage, attic, basement, or crawlspace; in the case of a heat-pump (a dual-system) it will be located outside of the home.
What is the best type of central heating system?
A combi boiler is often seen to be the main evolution of classic boiler-based central heating systems, using a combi boiler as the main feature. These combi boilers are much more efficient and do not waste energy by heating water that is not used but can also retain the mains pressure very well.
How does central air affect electric bill?

Is central air expensive to run?
Your air conditioner costs about $3.84 per day to run. Multiply that by 30, and you’ll find that you’re spending about $115.20 per month.
Is central heat cheaper than electric heat?
Gas central heating uses a mains gas supply that is generally a lot cheaper than the equivalent amounts of electricity would be. For this reason the gas central heating units are a far better choice than the electric units would be. You will save a lot of money by installing the pipes to bring the gas to the unit.
Is air conditioning cheaper than gas central heating?
So, it could save me money? The answer to this is yes, the saving will depend, of course, on the amount that you use it, but air conditioning units are more economical than central heating.
