A ducted heating and cooling system is one of the most effective ways to provide consistent, whole-home comfort. However, the performance of any HVAC system depends on far more than the equipment itself. Proper system design, accurate equipment sizing, well-engineered ductwork, and effective duct sealing and insulation all play a critical role in determining comfort, efficiency, indoor air quality, and long-term reliability.
At Lawrence Air Systems, we believe that the best heating and cooling systems do more than make a space hot or cold. Our approach focuses on designing complete comfort systems that deliver balanced temperatures, healthy airflow, energy efficiency, and dependable performance for years to come.
Ducted HVAC systems distribute conditioned air throughout your home or business using a network of supply and return ducts. These systems can be powered by:
One of the most common mistakes in the HVAC industry is selecting equipment and designing ductwork based solely on square footage. Every home is different, and factors such as insulation levels, window placement, air leakage, ceiling heights, occupancy, and building orientation all affect heating and cooling requirements.
Even the most advanced heating and cooling equipment cannot perform properly if the ductwork is poorly designed.
Unfortunately, many homes have duct systems that are undersized, improperly balanced, poorly sealed, or inadequately insulated. These problems often lead to:
Leaky ductwork is one of the largest sources of wasted energy in many homes. Conditioned air that leaks into attics, crawl spaces, basements, or wall cavities never reaches the rooms it was intended to serve. For example, a 1 inch hole in your attic ductwork is the equivalent of a 10”x10” window open in your home year-round!
As conditioned air travels through ductwork, it can gain or lose heat if the ducts are located in unconditioned spaces such as attics, garages, crawl spaces, or basements.
