Any good HVAC contractor worth their saltwill tell you that there are two main ingredientsto selecting a heating/cooling system that doesits job. First of all, they should explain that thenew equipment must be sized properly in order toprovide the right level of comfort in your home.Then, they should explain that proper sizing andinstallation makes the system deliver balancedairflow, so you dont suffer from hot and coldspots inside your home.
To do this, a room-by-room heat loss/gaincalculation should be performed on all the roomsof your home to determine the ideal equipmentsize. It may not be rocket science, but if not doneproperly, or at all, it can have a huge effect on theeveryday comfort of you and your family.Your contractor should also point out thatyour systems air ducts must be properly sized inorder to move the right amount of warm or coolair into all the rooms. The number of angles andthe overall length of the ducts will also need to betaken into account.
In many of todays homes, flexible ductwork(flexduct) is used. These insulated flexible tubesare laid across the attic or under the floors. Youknow where they are, but probably never check tosee if the connections are tight, if a section mighthave come loose over time, or if ducts have beenpunctured, kinked or blocked.
By making sure your ducts are sealed properly, are unobstructedand have no leaks, you can save more of theenergy thats required to heat and cool your home.When your home comfort system is properlydesigned and maintained, everything workstogether at peak efficiency, giving you balanced,comfortable heating and cooling all year round.
