Get Air Duct Testing & Stop Wasting Your Money

Don’t let your money leak away through your leaky ducts. Contact All Gas Heating & Cooling, Inc. to request an air duct test.  Our technicians will examine your ducts to determine their condition and make any necessary recommendations for sealing. The entire process is a quick, reliable, and cost-effective way to ensure you aren’t wasting energy and cash.

Studies indicate that 10% to 30% of heated and cooled air is lost leaky ducts—along with the energy and money spent treating that air. Properly sized, installed, and sealed ductwork will make your heating and cooling systems significantly more efficient. Energy loss is not the only concern. Duct systems can also affect the comfort of your family, as well as your indoor air quality.

Air duct testing locates leaks or damage and determine the right areas to focus on repairs. Since your ducts are an integral component of your heating and cooling system, they offer one of the best opportunities to increase your energy efficiency, boost your comfort, and manage your utility bills. Get a duct leakage test done to gauge the efficiency of your HVAC system. Making just a few simple repairs to your leaky ducts can reduce your overall energy expenditure dramatically, especially on hot summer days when your system may already be straining to deliver comfort and clean air to every room.

What an Air Duct Tester Does

Find out what condition your ducts are in by hiring our trained air duct technicians. Duct testing is the process of using calibrated, mechanical equipment to measure the amount of airflow that is lost through the duct system when it is at normal operating pressure. While some joints or seams may have only small leaks, other sections may be completely disconnected. This testing indicates the relative leakiness of the ducts and helps determine whether the ducts should be sealed, repaired, or renovated. Speak to our certified air duct technician after he the examination is complete to find out his or her recommendations for your system.

When to Request a Duct Leakage Test

Know when to request testing to gain the most savings. A duct leakage test is strongly recommended when a new heating or air conditioning unit is being installed. If the existing duct system is leaky and inefficient before the new unit is put in, it will still be leaky and inefficient after installation— unless the ducts are tested and sealed. It does not make sense to invest in a new, energy-efficient HVAC unit unless the duct system is also energy efficient.

Air duct testing is also recommended when a diagnostic tune-up is performed on a heating and air conditioning unit. A diagnostic tune-up can improve the operating efficiency of the unit itself, but the overall efficiency will still be less than adequate if the duct system is not in good condition.

What to Do with Your Duct Pressure Testing Results

When you get your duct pressure testing results, several different procedures may be recommended to improve your system’s efficiently. One of the most common recommendations is duct sealing. Duct sealing involves following established procedures to apply approved materials that seal air leaks.

Your air duct technician will determine the location where sealing is needed. Common locations include the supply and return plenums (which are connected to the furnace cabinet), starting collars (where ducts are connected to the plenums), fittings in the duct runs (Y's, where ducts branch off, and elbows), and splices within the duct run, and terminations where the ducts connect to the supply registers. The most important leakage areas are in the supply and return plenums, since these areas are closest to the HVAC system and under the highest pressure when the system is operating.

All sealing must be performed according to current Massachusetts Building Codes and any related energy efficiency program standards. These codes and standards address the type of mastic sealant, pressure-sensitive tape, and band ties used to correctly seal duct systems. The proper tape used for duct sealing will have a UL 181 marking or label on the outside surface of the tape. Likewise, the proper duct mastic sealant will also have a UL 181 label. To find out whether your duct pressure testing results indicate a need for sealing or another type of repair, speak with our technicians.
