SA stands for supply air. Air is delivered to your space from a sort of air handling unit(fan). This is the conditioned air whether heat or cooling. This air would be returned to the air handling unit to be reconditoned through the return air(RA) duct .

What are HVAC technicians?
HVAC technicians are Heating Ventilation, and Air Conditioning Technicians, we work on air conditioners and refrigeration stuff
Who is the founder of HVAC?
Sir Willis Carrier
What is cb30m514p?
Model # for Lennox HVAC unit
What does a HVAC technician do?
A good one makes a lot of money!! We do everything from installs to service. The latest thing is getting leed certification. Once I get it I will be making six figures and working half as much!
What is behind a dashboard?
The HVAC ductwork and HVAC compartment, and a whole lot of wiring.
What is hvac trade?
HVAC stands for "heating, ventilating & air conditioning". These are the people who install and maintain your furnace and air conditioner and the ductwork associated with them.
How much does it cost to replace a 4.5 ton HVAC unit including installation?
$depends on if the existing ductwork can be used.
What are the pros and cons to a package unit system for HVAC?
Drop it in, connect the ductwork and wiring that`s it. No field piping, leak checking,evacuation or charging.
What are the parts of an hvac unit?
There are a lot but some of them are * Fan * Coils * hot water piping * chilled water or refrigerant piping * Pumps * Distribution system(ductwork)
What is static pressure in a HVAC system?
Static pressure in an HVAC system refers to the resistance to airflow in the ductwork and system components. It is one of the key metrics used to measure the performance of an HVAC system and ensure proper airflow distribution. Monitoring static pressure helps HVAC technicians diagnose issues such as blockages, filter restrictions, or improper duct sizing.
If I get a new hvac system, will they use the existing ducts?
So long as your ducts function properly the cheapest option is to keep them. In fact installing ducts is a very large portion of the labor costs and you'd probably have to remove the old ones. The one caveat would be if your old ducts weren't properly insulated you'd want to either replace them or fit them with insulation. It depends on the system you are having installed as well as the existing ductwork. Consideration will be given to the age and condition of the ductwork, whether it is up to code and whether it provides the most efficient and safe delivery of heating and cooling from your new system. In older homes, for example, the ductwork may have been used in conjunction with an oil furnace or a coal burning heating system. That ductwork would best be removed and replace with new, clean, efficient ductwork. Talk to the HVAC contractor for the best advice.
What does a mechanical engineer in HVAC do on a construction site?
A mechanical engineer would help with the ductwork and installation of the air conditioning and heating systems. They may also have other abilities based on their mechanical engineering degree.
Where are some good places to buy ducting supplies?
Good places to buy ducting supplies is online through a website or locally at your HVAC wholesaler. Ductwork is a wholesaler that provides good prices to contractors and retail business.
Cost to switch from steam heat to hvac?
Need more info. Two pipe steam can be converted to a water boiler fairly reasonably. You can choose from equipment that will push 95% efficiency. If by HVAC you mean a/c also, it is a totally different animal, and would cost whatever for the equip, ductwork, (if not going to a ductless mini split), etc.
How do you measure friction loss in duct work?
Friction loss in ductwork is typically measured using the Darcy-Weisbach equation, which takes into account the duct size, velocity of the air flow, duct material, and length of the duct. By calculating the friction factor, you can determine the amount of pressure drop or loss due to friction in the ductwork. This information is essential for designing efficient HVAC systems.
What kind of a system is ductwork?
Ductwork is simply a duct system. Ducts are essential to the circulation of air, and ductwork describes a range of duct related fields, such as duct design.
