Our Approach

Most HVAC systems are installed using rough estimates—not actual calculations. That leads to higher energy bills, uneven temperatures, and systems that fail sooner than they should.

At Phil’s Good HVAC, we take a different approach.

We provide professional HVAC design services using Wrightsoft HVAC Design Software and industry-standard Manual J, S, and D calculations to ensure your system is designed specifically for your home or building.

Why Proper HVAC Design Is Critical

Proper HVAC design eliminates issues by ensuring your system is accurately sized and engineered for your space. An improperly designed HVAC system can cause:

  • Hot and cold spots throughout your home
  • Higher monthly energy bills
  • Short cycling and premature system failure
  • Poor airflow and humidity issues
  • Reduced indoor air quality

What We Offer

We provide complete system design using three key industry standards.

Manual J Load Calculation

Manual J load calculation determines exactly how much heating and cooling your home requires.

We analyze:

  • Square footage and layout
  • Insulation levels
  • Window types and placement
  • Climate and sun exposure
  • Occupancy and usage

Manual S Equipment Selection

Manual S ensures your HVAC equipment matches the results of your load calculation.

We:

  • Select properly sized units
  • Match system capacity to your home’s needs
  • Optimize for efficiency and performance

Manual D Duct Design

Manual D focuses on designing your duct system for proper airflow.

We:

  • Design duct layouts for balanced airflow
  • Size ducts correctly
  • Reduce static pressure issues

Powered by Professional HVAC Design Software

We use Wrightsoft HVAC Design Software—a professional-grade design tool used by top HVAC engineers and contractors.

This allows us to create precise load calculations, model system performance, design accurate duct layouts, and generate detailed reports for permits and inspections.
