Unfortunately, as a study in the Journal of Energy and Buildings found, HVAC systems come with a high environmental cost amounting to 40% of energy consumption in all residential sectors. This comes chiefly from heat transfer , but also from air cleaning processes and lost energy. Clearly, huge efficiencies need to be found in the HVAC/air conditioning sector – and innovation is providing. The air we breathe A large component of the inefficiency of HVAC is through the air filtration it undertakes. As outlined by Consumer R ...
