There is no answer to that, does the house need some demo to install the duct work or a lot? Are there beams or obstructions in the way?Even the costs of heating units vary a lot. Your best choice is to phone a few heating companies and get them to come in and give you a free estimate, takes all the guess work out of it.
The air is returning at a lower velocity, so you need a larger size duct.
1" Duct Board has an R-Value of 4.3
With duct tape I install and maintain duct work for a living if you want to seal the joints just wrap the tape around the duct. If you need to cover a hole you will need to screw a piece of metal on the duct over the hole and tape over the edges of your patch. this is the simplest and cheapest way I know to do it.
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.

I think it means "return air" - a duct for a ducted heating and/or cooling system
The purpose of an air duct cleaner is to clean the heating and cooling system components of forced air cooling in one's house. It is done so that there is less indoor pollution and a lower level of contamination.
To calculate the formula for duct sizing divide the room load by the whole house load. Next multiply those results by the equipment CFM.
Air duct cleaning is a professional cleaning service that removes debris and contaminants from inside the air ducts as well as from mechanical components of the heating and cooling units of the HVAC system.
Duct cleaning generally refers to the cleaning of various heating and cooling system components of forced air systems, including the supply and return air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, condensate drain pans (drip pans), fan motor and fan housing. A1 Air Duct in Dallas offers Duct Cleaning Services at affordable prices.
The air temperature difference inside a duct refers to the variation in temperature between the air entering the duct and the air exiting the duct. This temperature difference is influenced by factors such as the heat gained or lost through the duct walls, the efficiency of the HVAC system, and any insulation present in the ductwork. Monitoring and optimizing this temperature difference is important for ensuring effective heating or cooling of the space.
Wet bulb temperature is measured as part of the air temperature when a heater is running. It is measured at the return air grille (near the return air duct) or at the supply air grille (near the supply air duct). It is important to measure wet bulb temperature in the heating mode because it indicates the amount of moisture in the air and helps to determine the amount of cooling or heating that is needed. Wet bulb temperature is measured at the return air grille.Wet bulb temperature is measured at the supply air grille.Measuring wet bulb temperature in the heating mode helps to determine the amount of cooling or heating needed.
Heating duct tape can release potentially harmful fumes due to the chemicals used in its adhesive. It is best to avoid heating duct tape or using it in high-temperature environments to prevent the release of toxic fumes.

To calculate the duct diameter, you need to consider the airflow requirements, velocity of air in the duct, and the friction losses. Use the Duct Sizing Chart or an online calculator to determine the appropriate duct diameter for your system based on these factors. It's important to ensure that the chosen diameter can handle the required airflow without causing excessive pressure drop.
