Prevent Wallet-Drain Due to Leaky Air Conditioning Ducts

Leaky ac ducts bring about poor home cooling, extended waste of one's and expensive gulps of wallet-drain. Yet inferior AC duct connections are common in homes throughout the nation.

It's a true simple matter: Efficient home cooling involves more than merely pumping refrigerated air in a hot house. It is a procedure for heat exchange that corrects rather than conquers the inner liveable space. To be effective, your house air-con system must circulate the present air while stripping heat and humidity in the enclosed environment. A home with leaky air cooling ducts doesn't perform the job effectively.

A 20 Percent Waste Factor

According to federal Energy Star reports, the average home air-con system looses up to 20 % efficiency through leaky ductwork. Here is a full-range of benefits you can gain by correcting the problem:

** Lower energy bills

** Lower repair costs

** Fewer repairs

** More efficient system

** More comfortable rooms on account of better system distribution of air flow

** Cleaner indoor air because of reduced intake of irritants and allergens

** A sense of personal environmental stewardship

** Peace of mind in having an HVAC system that functions at peak efficiently and safety.

Sealing Your Home's Leaky AC Ductwork

Simple as it can certainly sound, inspecting and restoring your home's air conditioning duct system could be hot, sweaty and risky. Most likely, you may be necessary to enter the crawl space. In some events, you'll must go into the attic. Furthermore, you could possibly have to work with home insulation materials, restricted maneuvering space and darkness.

Before beginning the task, please take a flashlight and poke your mind into the home's crawl space. On some houses, this space is indeed tight that even air-con repair professionals groan before entering. If you are frightened of snakes, hate spiders or have certain closterfobic responses to tight places, just close the hatch and call any local AC service center.

Still want to do the work yourself? Here goes:

1) Proper Clothing - Pull out or purchase a mechanic's jumpsuit. A cheap one costs around $15.00, but better protection arises from high quality equipment. A jumpsuit provides you with full body protection against dirt, grime and creepy crawling things. It also has an extended array of pockets for carrying choice tools.

2) Tools - Sealing AC ductwork doesn't take lots of tools. You need:

** Closable box cutter with extra blades.

** Flashlight equipped with a focus adjustable base.

** One-inch wide, extended-reach paint brush.

** A standard dust mask

** Tin snips and tie-down straps, the 1st for trimming back joints and the second for re-hanging fallen ductwork.

** Backup flashlight for emergency exit.

** A roll of two-inch wide or three-inch wide, cold temperatures HVAC Aluminum Foil tape.

** A four foot amount of one-inch PVC pipe by having an elbow on one end - through the moving fallen insulation, left behind debris and if necessary an aggressive snake.

** HVAC certified sealant that fits the next testing procedures: ASTM E84, NFPA 255 or UL 723. The flame spread rate have to be less than 25. The smoke development rate must be under 50. These products might be purchased in a caulk-tube format, but you should also utilize a brush to the sealing.

3) Sealing Process - Making Your Air Conditioning Ducts Airtight

This is visual process. In the event of holes in flex duct - often produced by critters trying to stay warm during the winter - you have to apply cold temperature HVAC Aluminum Foil tape. If the insulation is missing, you may must acquire additional flex duct, create a cut then connect and reseal the finished work.

To seal connections and split-joints apply tape and/or sealant as seems best to the situation. In the event that the joints aren't cut correctly, use box cutters or tin snips as suits instances to produce a better fit after which apply tape or sealant.

To seal vents on the room access point, apply certified HVAC sealant. Take your time. Make certain that the caulk spreads fully and retains experience of the point of application. Be sure to seal the outside from the floor joists in which the return air connection passes through the flooring. It also never hurts to cap-off the within wall cavities the place that the flashing passes through.

If necessary, perform the same processes within your attic and/or garage.

Additional Notes on Sealing Air Conditioning Ducts

Perhaps all this seems overkill. Think about what type consequences will come about if lungs developed a group of pin-holes. It wouldn't take long for breathing to get labored and inefficient. Every small leak enhances the accumulated home cooling losses and expenses.

** Special Warning: If you encounter water or other indications of sewage leakage, emerge from within the house. Find a professional plumber to deal with the problem, and acquire questions of safety settled before continuing with your AC duct system repairs.

So get dressed for your occasion. Gear up with all the right tools. Seal your leaky air-con ducts. Isn't it time you add a finish to unnecessary wallet-drain.
