Homes designed and built in recent years are more airtight and energy efficient than in the past. To obtain this airtight design, house wraps, newly designed windows and doors, sealing caulks and other insulating materials are used to create a seal for optimum energy efficiency. The resulting benefit is fewer drafts, which lowers the cost to heat and air-condition a home. But pollutants retained in airtight buildings can be hazardous to their occupants and can jeopardize structural integrity.
Dedicated systems are now being required to remove old air and supply fresh air to the living space.  Energy Recovery Ventilators (ERV's) and Heat Recovery Ventilators (HRV's) are the most efficient systems to accomplish this.
These are just a couple examples of ventilation.  You may need a simple bath fan or perhaps dehumidification/ventilation for your indoor pool.  Lawrence Air Systems can service all of your ventilation needs. Since every home and business has its own needs and demands, a free estimate will ensure you'll get the right system for your application.
