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.
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

Very few homeowners realize the need to drain a few gallons of water from your water heater twice a year. Regardless of the type of water heater you have, gas or electric, water heaters can develop a build up of sediment at the bottom of the tank. This build up can cause the water heater to operate inefficiently, shortening the life span of the appliance. Prior to draining water from your tank, you need to understand the proper way and safety concerns of performing this task. It is very important that when you are doing this maintenance to your water heater, you make sure the appliance is turned off and that you protect yourself from a potential burn.… Read the rest

I’ve listened to some outrageous claims from window replacement companies. The usual sales tactic is how much return on your investment by replacing your windows you’ll get. The fact of the matter is the new windows could take anywhere from 13 to 20 years to receive your investment back. Unfortunately, a lot of consumers believe the window company’s claims. I hear this myth repeated many times while doing home inspections throughout the Dallas and Fort Worth areas.
Don’t get me wrong, new windows can be a very good thing, but it miffs me just a bit that a vast amount of dealers in the market try to hype the return to make it sound as if your investment will be recouped in no time at all.… 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

Keeping the Lights on With High Quality Solar Inverters
No matter the size of a solar photovoltaic installation, it requires a solar power inverter in order to convert the current provided by the solar panels into usable AC current. Due to this, hobbyists and industrial concerns alike should only select the highest quality inverters for their use. Fortunately, SMA and Aurora solar inverters are examples of premium inverters.
