Leaks and other defects in heating and air conditioning ductwork can be discovered with ease and at a low-cost using smoke testing. The superior way of producing smoke is through a chemical reaction which eliminates the need for expensive equipment and time-consuming procedures when locating HVAC leakage. In Indian houses and offices, there are about a million miles of ducting. More than two-thirds of them, according to industry experts, are leaking enough to warrant sealing or repair. Leaky ducts can considerably raise air conditioning and heating expenditures, impair device capacity and performance, and cause potentially severe indoor air quality issues. In reality, duct leakage is to blame for many of today's home comfort issues.

Forced air duct leaks are now recognized as a significant source of energy waste in both new and existing homes and commercial spaces. According to studies, duct leakage can account for up to 25% of total house energy loss, and it has a higher influence on energy use than air penetration through the building shell in many circumstances. Duct leakage can also hinder heating and cooling systems from performing properly, resulting in hot or cold rooms as well as humidity issues.

Due to leakage in the air-conditioning supply air ducting, the expensive conditioned air is discharged into the attic, crawlspace, or garage rather than into the house. This is something that Smoke Test can discover and rectify in a timely manner.

Through return leakage, outside air (hot in the summer, cold in the winter) is pulled into the duct system, decreasing efficiency and capacity. Return leaks can overwhelm air conditioning systems dehumidification capacity in humid conditions, causing houses to feel clammy even when the air conditioner is switched on. This is something Smoke Test can detect and correct in a timely manner.

In exchange, there are leaks. Dust, mould spores, insulation fibres, and other contaminants are carried into the house by ducting from crawlspaces, garages, and attics. Smoke Test is capable of detecting and correcting this issue.

Due to depressurization induced by duct leaks and imbalanced duct systems, combustion products (from furnaces, water heaters, and fireplaces) may spill into the house.
