Comfort Starts with Precision
Perfect comfort, lower bills, and peace of mind, backed by science.
Engineered Comfort. Backed by Data. Built on Precision.
Comfort isn’t luck; it’s the outcome of innovative design and exact calculation. At ON Point, we provide precise HVAC load calculations. This ensures that your system design works as intended. Efficiently, compliantly, and customized for your build.
If you’re building a new custom home or renovating, our reports provide your team with the correct data. This helps size equipment, simplify permits, and keep construction on schedule.
Why Precision Matters
When it comes to heating and cooling, close enough isn’t good enough.
An oversized system short-cycles, wastes energy, and wears out early. A small system can’t keep up, leading to uneven comfort and possible code violations.
We perform Manual J–J-style Heat Loss and Heat Gain Calculations. These calculations consider all key factors, including insulation values, solar gain, and occupancy. This way, we provide accurate load data that meets code requirements.
With ON Point, you get:
✅ Even, consistent comfort throughout the home
✅ Efficient operation and lower long-term energy use
✅ Documentation ready for building permits and rebate programs
✅ Confidence that your HVAC system is designed, not guessed
What Makes ON Point Different
Most contractors estimate. We calculate. Then we collaborate.
We begin with your project goals. This includes your preferred heating and cooling type, performance targets, and the home’s design intent. Whether you prefer in-floor heating, a heat pump, or a hybrid system, our calculations are tailored to meet your needs and comfort goals.
Every home design is unique. We review your architectural drawings to verify insulation values, window placement, solar exposure, and ventilation. The result: exact load data that ensures your system size, ductwork, and layout are both code-compliant and ready for real-world use.
Our process integrates seamlessly with your builder, architect, or mechanical installer. We provide clear, organized documentation that’s easy to use. This helps reduce change orders, delays, and confusion during the construction process.
You’ll get a clear report. It will outline your load calculations, equipment capacity, and system recommendations. This is ready for permit submission or approval for an energy-efficiency program.
Our process: simple, precise, reliable
- 1. Listen & Learn We begin by learning about your plans, chosen systems, and project goals. This includes your comfort expectations and performance standards.
- 2. Calculate Precisely. We use Manual J methods and local climate data to find your project’s heating and cooling loads. No assumptions, no shortcuts.
- 3. Deliver Clear Reports. Our visual reports display needed system capacity, room-by-room performance, and key design data. They’re easy to understand and submit for permits.
- 4. Support Your Team. We work directly with your installer or builder. This way, we make sure the design is done correctly and works as planned.
