Feeling unexpected cold spots or a constant subtle breeze even when the windows and doors are shut tight? While Kiwi homes, especially older ones, can have their share of draught sources, leaky duct work is a major, often overlooked, culprit. If your heated or cooled air is escaping through gaps in the ducts before it even reaches your rooms, you'll notice those uncomfortable draughts and a home that just won’t stay consistently warm or cool.

Are your heating and cooling costs surprisingly high, especially compared to homes of a similar size? When your conditioned air leaks out of ducts hidden in walls, ceilings, or under floors, your HVAC system has to work much harder and longer to achieve and maintain your desired temperature. This wasted energy translates directly into higher power bills – a common complaint for many New Zealand households. LIMS Aeroseal can help significantly reduce this energy wastage by sealing the leaks, meaning your system runs more efficiently, saving you money.

Do you find that some rooms in your house are always too hot in summer, while others remain stubbornly chilly in winter, despite your best efforts with the thermostat? This uneven temperature distribution is a classic symptom of leaky or poorly performing duct work. Leaks can cause conditioned air to be lost en route, meaning distant rooms don't get their fair share. By sealing the entire duct system from the inside, Aeroseal technology ensures air is distributed more evenly, leading to consistent comfort throughout your home.

Constantly dusting surfaces, no matter how often you clean? Leaky return ducts can pull dusty, unfiltered air from spaces like your attic, crawl space, or wall cavities directly into your ventilation system. This dust then gets circulated throughout your home. Similarly, leaks in supply ducts can create pressure imbalances that draw in outside air and particles. If excessive dust is a persistent problem, your duct work could be the source, impacting your indoor air quality.
