How Everest Air assesses your home: on-site evaluation and load calculations

Every professional furnace installation begins with a systematic on-site assessment. Everest Air Heating and Cooling conducts a comprehensive inspection and performs Manual J load calculations to determine the precise heating requirement for your home.

Key elements of the on-site assessment:

• Home envelope review: Inspect insulation levels, window types, air infiltration, and attic and crawlspace conditions common in Alnwick homes.
• Duct system inspection: Evaluate duct size, routing, insulation, leakage, and accessible return pathways. Older homes often need sealing or resizing.
• Fuel and venting evaluation: Confirm gas or propane line sizing, presence of adequate combustion air, and condition of chimneys or direct venting paths.
• Thermostat location and zoning potential: Identify opportunities for programmable or smart thermostats and zoning for multi-level homes.
• Manual J load calculation: Use actual home data (square footage, orientation, insulation, window area, occupancy, and local design temperatures) to produce an accurate heat loss value instead of relying on rule-of-thumb sizing.

Why Manual J is critical in Alnwick:

• Tennessee winters can vary; an accurate load calculation prevents oversized units that short cycle in mild weather and undersized units that fail during cold snaps.
• Older homes in the area often have heat loss patterns that size changed equipment differently than new homes.

Selecting the right furnace: fuel type, efficiency, and features

Choosing the correct furnace involves matching home needs, fuel availability, efficiency goals, and long-term operating costs. Everest Air helps homeowners compare options and explains trade-offs clearly.
