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.
With Winter around the corner, now is probably a good time to get that fireplace in shape for this season of sitting by the fire with a good book, spouse or significant other.
Even with our mild winters here in the Dallas Fort Worth area, the Chimney Safety Institute recommends that homeowners who light fires in their fireplaces three or more times a week during the heating season should have their chimneys inspected and cleaned once a year.
If unseasoned wood is burned in the fireplace, twice-a-year cleaning and inspection may be necessary, because unseasoned wood usually burns at a lower temperature than seasoned wood, causing more smoke and therefore more creosote.… Read the rest
Although it seems quite expensive initially, when it comes to providing electricity for your household, solar power is the best way to go long-term wise. If you want to save money on your electricity bill or live a greener lifestyle, then you should consider solar power for the home.
The initial cost of solar panels is very hefty, often costing a homeowner tens of thousands of dollars. However, once you get solar panels, the cost of your electricity bill will go down or you may not have to pay anything for electricity at all.
Basically, solar panels are a one-time cost while you’ll need to pay electricity bills every single month for the rest of your life.… Read the rest
How many people actually maintain their lawn equipment and store them properly before the winter season hits. In this article, I will show you how to perform some common routine maintenance on your gas powered mowers, weed trimmers and spreaders to insure they will operate properly for next spring.
Fill the gas tank on your mower just enough to complete the last mowing. Afterwards, run the mower until it runs out of gas. If gasoline is left in the tank all winter, it turns stale and collects water droplets from condensation. If to much gas is in the tank to run out, you can drain it or worst case, purchase some fuel stabilizer from your local auto parts store and add the recommended amount to your tank.… Read the rest
A moisture meter is a device designed to measure the moisture content of various building materials, such as roofing, siding, insulation, drywall, plaster, wood, tile and fiberglass. Structural and safety hazards, such as mold, rot and decay are all potential consequences of elevated moisture levels in these materials. An inspector can use a moisture meter to locate moisture that would not otherwise be apparent.
Here are a few ways that inspectors may find moisture meters useful:
•A moisture meter can be used to determine whether a material is moist enough to allow mold to grow. Mold will begin to accumulate on surfaces that contain approximately 20% moisture, although this value varies based on vapor pressure and other factors.… 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

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
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
You may be surprised at just how much your window treatments can affect the appearance of a home. Many people tend to see them simply as additions to the home that are only there to serve a practical purpose. This couldn’t be further from the truth as certain window treatments can help you achieve certain looks and effects in the home. One such example of this is the understated, subtle option of wooden venetian blinds, which can really play a big part in helping you give your home a modern appearance.
One of the very first things that people consider when it comes to any factor of interior design is colour, and venetian blinds are no exception to this rule.… Read the rest
