There are two main components for an HVAC system, and they must work simultaneously to efficiently provide heated air. The first component is the furnace, and the second component (hidden and mostly overlooked) is the air duct system through which the warm air is distributed into the house.
The air ducts have a variety of elements. To function effectively, they must be completely sealed and insulated. Having a San Francisco HVAC expert inspect and/or repair the system could be a big step towards making your home comfortable. Meanwhile, you may also be lowering your heating and air conditioning bills. Here are a couple of points to bear in mind throughout the inspection:
- One of the most important things to look for is any physical damage to one or more of the air ducts. This includes any dents to pipes, holes in flexible-type ductwork, or ducts which have become loose from their connections. It is also important to check the insulation on the ductwork to ensure the entire system is uniformly covered. Insulation can sag over time, and so it is essential to have it checked routinely.
- Check out the boots. There is a fitting at the end of each duct, which is called a boot. The boot is the opening in the flooring or ceiling of the house, and it also functions as the connection place for the register. At this point, you need to verify that the boot itself is completely covered with insulation. Insulation can slide down, and may not be fully enclosing the fitting. Sometimes, you may find a floor which was cut too big for the boot. This will result in a gap, and will leave your home susceptible to drafts that come into the home from unheated places.
- Ducts in garages are occasionally neglected, and any ductwork in the garage can lose a tremendous amount of heat. Ensure that any air ducts in the garage are totally insulated.
- For those who have a heat pump, or a HVAC system which also has air conditioning, the exterior of the duct insulation should be covered to prevent moisture build up. Inspect all of the ductwork, including the boots, and see if the wrapping remains intact and covers all the insulating material.
A HVAC repairman can easily identify any issues that may cause problems in the long run. Your best bet is to have an expert do the job. Don’t fall into the trap of thinking you can fix the problem with a little duct tape — it definitely won’t last very long.
