HVAC (pronounced either "H-V-A-C" or "aitch-vak") is an acronym that stands for the closely related functions of "Heating, Ventilating, and Air Conditioning"- the technology of indoor environmental comfort. HVAC system design is a major subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. Refrigeration is sometimes added to the field's abbreviation as HVAC&R or HVACR, or ventilating is dropped as in HACR (such as the designation of HACR-rated circuit breakers). HVAC is particularly important in the design of medium to large industrial and office buildings such as skyscrapers and in marine environments such as aquariums, where safe and healthy building conditions are regulated with temperature and humidity, as well as "fresh air" from outdoors.

I have forced air heating using natural gas but I live in a climate where the humidity is quite high. I believe you are experiencing these difficulties from the drying action in your nose and throat from the hot dry air being circulated by your forced air fan. I could only suggest the use of a humidifier to help relieve this condition. If you are not in a "dry" type of atmosphere you've got me. Have you had you furnace checked for a leak in the heat exchanger ( usually if the furnace is over 15 to 20 years old it has this potential. A leak in the heat exchanger can cause CO (carbon monoxide) to be blown into the rooms through the heating ducts.

Q. I recently found a job for a Mechanical Contractor and I want to know the steps of doing an estimate, HVAC and Plumbing.
