. This is a good thing for energy efficiency and the ability to control the interior environment. However, this fact places more emphasis on a well-designed and professionally installed heating and air system. When there is very little penetration of outside air, most of the breathable air in the home will need to be supplied through this system.
One benefit of a well-designed system is efficiency. If the units installed are too small for the square footage of the home they will be overburdened and will not perform efficiently. The air inside the home will also not be cooled or heated as well and will reduce the overall comfort of the dwelling. A unit that is too big is also inefficient, it will be able to heat and the cool the space well enough, but the cost is more expensive than is required. A set-up that is matched to the square footage of the home will provide adequate heating and cooling at the minimum affordable installation cost.
Another benefit would be air quality. Many modern units have available as options humidifiers, dehumidifiers and air filtration. All these units will increase the breathability and comfort of the air stream coming into the home. Also, always remember to change all filters on a regular basis as recommended by the manufacturer. This will allow the system to always operate at peak efficiency.
Another benefit of having a system installed by a professional is maintenance. Most companies will provide an annual inspection service at little cost to the homeowner. This is necessary before each season to ensure there are no problems before heating or cooling have to begin. When outside temperatures are at their extremes is not the time to have a breakdown. These annual checkups can prevent costly and time-consuming repairs once the unit is being heavily used. Modern heating, ventilation, and air conditioning (HVAC) systems are complex pieces of machinery that are best installed and maintained by trained professionals.
A well-constructed, professionally installed system for heating and cooling will make a home a comfortable place to live and will add value and utility to any home. Having such a system professionally installed by a reputable contractor will also alleviate any concerns. Having the system checked at least annually will make sure it functions properly.
