FORT WORTH DALLAS HOME INSPECTOR ON LEAKING A/C DUCTS.
CENTRAL HEATING AND COOLING SYSTEMS USE AN AIR DISTRIBUTION OR DUCT SYSTEM TO CIRCULATE HEATED AND/OR COOLED AIR TO ALL THE CONDITIONED ROOMS IN A HOUSE. EVEN WHEN PROPERLY DESIGNED, DUCT SYSTEMS MUST BE INSTALLED CORRECTLY TO BE EFFICIENT, MAINTAIN UNIFORM TEMPERATURES THROUGHOUT THE HOUSE, OPERATE QUIETLY, AND NOT ADVERSELY IMPACT COMFORT OR INDOOR AIR QUALITY
AT LEAHY’S INSPECTIONS WE LOOK THE SYSTEM OVER AND IF THE DUCT WORK IS BAD AND LEAKING, I MAKE THE RECOMMENDATION TO REPAIR OR REPLACE IT.
MAKE SURE DUCTS ARE PROPERLY SEALED AND INSULATED IN ALL NON-AIR-CONDITIONED SPACES RUNNING FROM OUR AIR CONDITIONERS AND HEATING SYSTEMS.
DUCT LEAKS CAN BE SEALED USING MASTIC OR ACRYLIC-ADHESIVE FOIL TAPE. MASTIC ADHERES WELL TO MOST SURFACES AND PROVIDES AN EFFECTIVE LONG-TERM SEAL. MASTIC ALONE MAY BE USED TO SEAL CRACKS LESS THAN ¼” WIDE. FOIL TAPE CARRIES A 20-YEAR GUARANTEE IF APPLIED PROPERLY.
ANY SEALANT SHOULD CARRY THE UNDERWRITERS LABORATORY RATING (UL-181)SPECIFIC FOR THAT PARTICULAR TYPE OF DUCT. MOST DUCT MANUFACTURERS ARE NOW LISTING THE CLOSURE PRODUCTS THAT THEY ALLOW TO BE USED WITH THEIR DUCTS.
IF YOUR DUCTWORK IS UNINSULATED, CONSIDER ADDING 1½” TO 3″ OF INSULATION AND WRAPPING WITH AN EXTERIOR VAPOR RETARDER. SOME BUILDING CODES REQUIRE THAT DUCTWORK HAVE A MINIMUM INSULATION VALUE.
IF YOU SEE THE CONTRACTOR BRINGING IN DUCT TAPE, HIRE SOMEONE ELSE. IN THE PAST, MANY SYSTEMS WERE SEALED WITH A GRAY, RUBBER-ADHESIVE, CLOTH DUCT TAPE. THIS TAPE WILL EVENTUALLY FAIL DUE TO ITS SHORT-LIVED RUBBER-BASED GLUE. IF YOU SEE THIS KIND OF TAPE IN AN EXISTING HOME, BE SURE TO CHECK ALL AREAS WHERE IT IS ATTACHED TO THE DUCTS.
WHY DUCT INSTALLATION AND SEALING ARE IMPORTANT
THE EFFICIENCY OF AIR DISTRIBUTION SYSTEMS HAS BEEN FOUND TO BE 60-75% OR LESS IN MANY HOUSES BECAUSE OF INSUFFICIENT AND/OR POORLY INSTALLED DUCT INSULATION AND LEAKS IN DUCT SYSTEMS. PROPERLY DESIGNED AND INSTALLED DUCT SYSTEMS CAN HAVE EFFICIENCIES OF 80% OR MORE FOR LITTLE OR NO ADDITIONAL COST, POTENTIALLY SAVING A HOMEOWNER $50-200 OR MORE PER YEAR IN HEATING AND COOLING COSTS. DUCT SYSTEMS THAT LEAK AND/OR DO NOT DISTRIBUTE AIR PROPERLY THROUGHOUT THE HOUSE MAY MAKE SOME ROOMS TOO HOT AND OTHERS TOO COLD.
LEAKY AND UNBALANCED DUCT SYSTEMS FORCE CONDITIONED AIR OUTSIDE AND UNCONDITIONED AIR INTO THE HOUSE. THIS INCREASES HEATING AND COOLING COSTS AND MAY ALSO DRAW HUMIDITY, DUST, MOLD SPORES, AND OTHER CONTAMINANTS INTO A HOME FROM THE ATTIC, CRAWLSPACE, OR GARAGE AND RADON’S. MOST AIR CONDITIONING AND HEATING SYSTEMS REQUIRE SOME FORM OF DUCT WORK TO CHANNEL OR DIRECT THE AIR TO PLACES IN THE DWELLING WHERE THE CONDITIONED AIR IS NEEDED.
THERE ARE MANY TYPES OF DUCT WORK AVAILABLE AND OFTEN TIMES THE DUCT WORK CAN MAKE A BIG DIFFERENCE IN YOUR UTILITY BILLS. FOR THAT REASON, IT IS IMPORTANT THAT THE DUCT WORK IS INSTALLED CORRECTLY BY QUALIFIED INSTALLATION TECHNICIANS. A POOR INSTALLATION JOB WILL RESULT IN POOR PERFORMANCE, BAD AIR FLOW, LEAKY DUCT WORK SYSTEMS, AND HIGHER THAN USUAL UTILITY BILLS. IT IS IMPORTANT THAT YOU HAVE QUALIFIED PEOPLE DESIGN AND INSTALL YOUR SYSTEM FROM START TO FINISH SO THAT YOU GET THE BEST AND HIGHEST PERFORMING DUCT WORK SYSTEM MONEY CAN BUY. IT IS ALSO CRITICAL THAT THE AIR CONDITIONING DUCT WORK SYSTEM BE DESIGNED FOR THE AIR CONDITIONING LOAD.
The main purpose of a roof is to protect the home from the elements. Rainfall is the #1 culprit of water getting underneath the roof structure. Water needs to be shed away from valleys, chimneys, ridges, eaves, rakes, skylights, roof penetrations and roof to wall intersections. Water built up in these particular locations can cause serious damage to the structure in wood rot and not to mention mold which is known to cause respiratory problems. The water usually doesn’t just stop there, it can penetrate down the attic structure, to the ceiling sheet-rock or down a wall and cause even more serious issues.… Read the rest

One of the hottest trends in 21sthome decorating and design is the combination of antique furniture with modern and contemporary interiors. Antique furniture has always been around in flea markets, museums, and in privately owned shops, but recently, more and more ordinary people have preferred to incorporate the ageless appeal of every piece of it into their very own home. Antiques are a wonderful way to add depth and dimension to any part of the house. The superior craftsmanship behind each piece is just an icing on the cake.

When people think about blood sucking insects, they first picture a mosquito or tick. Did you know bed bugs are also blood suckers. The tiny, sneaky insects are spreading so rapidly across the United States that almost no region or area is unbitten, a new survey suggests. The United States has seen a 50-fold increase in bed bug infestations over the last five years, according to the National Pest Management Association. An entomologist told MSNBC, “It’s like the return of the wooly mammoth,” as many of his peers had previously never seen a single bed bug in their careers. The outbreak has affected most parts of North America and Europe, especially in urban areas.… Read the rest
Came across this a/c systems evaporator coil today. It’s amazing how lazy some people are. If you pay a professional to do a job, you expect to get a professional job done. The coil was so off level, condensation was standing on the left side of the pan whenever the a/c was running. Here in Texas, that’s most of the year. After years of this happening, the pan finally rusted through and is now leaking into the secondary pan and beyond to the plenum. The plenum is leaking onto the ceiling and wall of the bedroom below. Now we have a huge mess with water damage and mold.… Read the rest

While a deck can add style and a comforting place to entertain, it is far from a maintenance free addition. The proper maintenance is necessary to protect the life and appearance of your deck.
It is a common misconception that pressure treated wood, which is the wood most often used for decks, requires little maintenance. The pressure treating process involves the injection of chromated copper arsenate into the wood cells. Copper acts as a fungicide, while arsenic is an insecticide. While these chemicals protect against insects and fungus, they leave the surface vulnerable to the effects of rain and sun. Even redwood and cedar, two other common woods used for decks, can be damaged by the elements.… Read the rest

Kids Enjoy Decorating Their Own Bedrooms
Our kids are busy, smart, and clever. They have well-formed opinions for youngsters, and they firmly know exactly what they like and what they do not like. Unfortunately, that makes for some particularly vocal, opinionated kids. When we moved into our new home, we decided to let our clever, opinionated kids share their ideas on how their new bedrooms should be decorated. Any other decision would have spelled disaster.
