Further Bonus Coverage....Energy Efficient Homes 2

In the previous "bonus", EEH-1, talked abut the Attic. Before we leave the Attic...another component: your heating ducts. Need to check these for air leaking connections. "Tons" of heating can be lost thru these causing your heating unit to run far more than necessary.

In older homes your ducting is prob. either metal or asbestos. If it is the "A" word stuff...just LEAVE IT ALONE. Not causing any probs. unless it gets disturbed. Metal ducting, check the seams. They should be wrapped in insulation at the transitions and at the vents. Straight runs are often taped with "duct tape". Yup, that's where the name comes from. HOWEVER, "duct tape" has become as generic as referring to a spa as a "Jacuzzi". The "grey stuff" is not actually duct tape, and it comes in several grades. Manufactures just ref err to all of it as "duct tape". Actual
tape use for heating ducts is SILVER tape. The difference: the grey stuff will deteriorate over time, silver won't.

Therefore, if you find your ducting in wrapped in the grey stuff; pull it off and replace it w/silver. Yes, it really is worth it.

If the insulation is frayed, or missing, re wrap it. Note, this is NOT wall/ceiling insulation. It is actual insulation for wrapping ducts. Goes on w/spray adhesive. And, again, YES, it is worth it.

Related to the ducting is of course the furnace itself. If your unit is more than 10 years old, prob. only around 50% efficient; means it has to run twice as long to do its job. New one's often are 80% or better (and about 1/2 the size!) Clean and service it!!! at least at the start of the heating season....and that filter...how many of your actually replace it? Should be replace twice during heating season, once during AC. If not, it gets blocked, and not only does that impact your air quality, the fan hast to run longer to push the air through. All of these issues contribute to consumption of more energy.

In conjunction with the furnace, the thermostat. Most areas now require programmable units...but they are of no value unless USED. Makes sense, right. But how many of you have 'em, don't make full use of 'em? These are great for being more energy efficient. Set the timer to reduce, even turn off, the unit at night or when you are gone. Can be set to restart so home is "warm again" when it actually needs to be. Same applies to your AC usage.

For more Energy Efficient Home tips....stay tuned it!!!
