<body class='hmmessage'><div dir='ltr'> Hello,<br><br>I have a question regarding designing a central heating system and I would like your help.<br><br>Why does my central heating system has less cfm than my central cooling? Shouldn't they be the same since it's the same fan?<br><br>Also, I want to condition my rooms at 70 f during the winter season. Is it okay to set the "design temperature" of the central heating system to 72 f and let the heating loads bring it down to 70 f?<br> </div></body>
