SIZING (MANUAL J, S & D)

Why did I measure your whole house before quoting?

Equipment should be sized to your home, not to the old unit’s label. A Manual J load calculation figures how much heating and cooling each room needs; Manual S picks equipment to match; Manual D designs ducts to deliver it.

WHAT TO LOOK FOR

Signs you might notice.

  • A system that short-cycles or never shuts off
  • Humidity problems after a replacement
  • Quotes that just match the old tonnage

WHAT WE DO ABOUT IT

Every replacement starts with a load calculation. You get the numbers with your proposal.
