I will calculate heat loss and cooling load for your room addition

Adding a room, sunroom, or extension to your home? Don't guess on HVAC sizing. I calculate accurate heat loss and cooling loads specifically for room additions, helping you determine whether your existing HVAC system can handle the extra space or if a supplemental/mini-split unit is needed.

Room additions often have different exposure, insulation, and window-to-wall ratios than the rest of the house, which means they need their own careful load analysis rather than rough estimates. I'll help you avoid an uncomfortable new room that's always too hot or too cold.

What's included:

• Heat loss calculation (BTU/hr) for the new space
• Cooling load calculation (BTU/hr) for the new space
• Analysis of whether existing system capacity is sufficient
• Recommendation on supplemental heating/cooling options if needed
• PDF report you can share with your HVAC contractor
