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.
If you have fuel burning appliances in your home, you owe it to your family to have CO detectors installed. Carbon monoxide detectors are great devices to use when fuel-burning appliances are used in the home. They can be very useful for keeping watch on the CO levels in the home.
Carbon monoxide (CO) can be a sneaky killer, it’s colorless, odorless, poisonous gas that forms from incomplete combustion of fuels, such as natural or liquefied petroleum gas, oil, wood or coal.
• 170 people on average in the United States die every year from CO produced by non-automotive consumer products.… 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
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

These grants address quality of life issues and focus on creating supportive home environments regardless of age. Through a DFG, a more active role at work, at school, and around town may be enjoyed.… 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
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
When I decided to become a home inspector, I got into a habit of inspecting things everywhere I went. I honestly cannot help myself anymore, it’s just what I do. Being a father and just loving kids in general, I started noticing things when I would go to playgrounds in the Arlington, Mansfield and Burleson areas with my own kids or with my nieces and nephews that worried me about their safety. I recently pulled some information from the CDC website I thought I would share to remind parents of how important it is to keep you children safe from serious injury.… 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.
