Hvac Installations

The main objective of an HVAC system is to provide proper air flow, heating and cooling to each room in the house. To fulfill that goal it is important that you have a quality system, key design and proper installation of your HVAC system. Here, it needs to be kept in mind that HVAC installation is not a DIY project and you would certainly require help from a trained HVAC technician to successfully install the system in the house. There are certain things that has to be kept in mind if you are looking at the best results from your HVAC unit.


Choosing the rightly sized unit is of great importance for providing good amount of comfort. To determine the correct size of the HVAC unit that your home would require, the first step is load calculation. Load calculation is important to find out the heating and cooling requirement of your home. Depending on that an HVAC contractor will be able to suggest you the correct size of the unit.

The HVAC unit should be installed in such a way that the static air pressure drop across the handler is within the Manufacture and Design specifications so that the unit has the capacity to meet calculated load needs.


There should be sealed supply ductwork so that there is proper airflow within the rooms. At the same time, an HVAC unit will have to be installed with a return system sized to provide correct return air flow.

The return air duct should also be sealed so that proper air flow is provided to the fan and no polluted air is able to enter the HVAC system.

There should be balanced air flows between supply and return air systems so that neutral pressure can be maintained within the home.

The HVAC unit needs to be installed in such a way that there is almost negligible duct air temperature gain or loss between the air handler and room registers and between return registers and the air handler.

The HVAC unit must be properly charged with refrigerant so that it can function properly.

It is pertinent that the HVAC unit has proper burner operation and proper draft.


Now let us have a look at the approximate cost of an HVAC unit. In fact, it is quite difficult to determine the exact price of an HVAC unit because a lot of factors play an important role in determining the price of the unit. First of all the kind of system you are buying and the size of your home plays a crucial role in determining the price.

To understand the pricing strategy of an HVAC unit, it is important to understand the parts that we get with an HVAC unit. They are the following:

• Furnace

• Air Conditioner

• Duct work

• Thermostat


Each of these parts have different functions and you need to pay for every function that your HVAC unit does as part of the total cost. At the same time, for a home which do not have existing duct work the expenses will be a lot higher than a home which already has duct work installed.
