Your HVAC Experts—Reliable Comfort, Trusted Service!

In this episode of Cool Talk, we pull back the curtain on what really separates a long-lasting, high-efficiency HVAC system from one that breaks down early and costs you more in the long run.

Proper installation is more important than the brand itself — and we explain why.

Join us as we break down the key factors that make or break an HVAC system, including:

• Why choosing a licensed, NATE-certified contractor matters
• The importance of Manual J load calculations and proper unit sizing
• Why we always follow updated electrical, refrigerant, and ductwork standards
• Site prep, permits, code compliance — and how they protect your home
• The dangers of shortcuts like piece-rate installs and improper vacuuming
• How commissioning, digital testing, and ongoing maintenance extend the life of your system
• Our approach to using W2’d technicians (not subcontractors), full system cleanings, and bundling for better warranty support

If you're investing in a new HVAC system — or just want to know what to watch for during your next install — this episode will help you ask the right questions, avoid costly mistakes, and get the comfort you paid for.

Ever wondered how professionals determine the right size HVAC system for your home or building? In this episode, Hartzell’s Heat & Air demystifies the essential step of HVAC Load Calculations—a critical process ensuring optimal comfort, maximum energy efficiency, and long-term system reliability.

Using the industry-standard Manual J method by ACCA, accurate load calculations carefully evaluate your building’s heating and cooling demands by analyzing various key factors:

✅ Building Envelope:

• Discover how your home's size, layout, insulation levels, windows, doors, skylights, and air leakage influence your HVAC needs.
• Learn about the role of insulation types and ratings in preventing heat loss and gain.

✅ Climate & Geographic Location:

• Find out how outdoor temperature, humidity, sun exposure, and your geographic location (particularly tailored for Oklahoma’s unique climate) affect your heating and cooling loads.
• Understand the critical importance of design conditions defined by ASHRAE and local climate considerations.

✅ Internal Loads:

• See how the number of occupants, appliances, lighting, and daily activities contribute to internal heat generation within your home or building.

✅ Ventilation and Duct Systems:

• Learn how proper ventilation and accurately designed ductwork contribute to improved air quality, comfort, and energy efficiency.
• Understand specific considerations from duct insulation to minimizing duct leakage.

✅ Additional Factors (Manual J):

• Explore often-overlooked details like blower heat, moisture migration, and winter humidification loads, and learn about the significance of Adequate Exposure Diversity (AED).

✅ Why Size Matters:

• Discover the pitfalls of oversized and undersized HVAC systems, including poor comfort control, inefficient energy usage, and shortened equipment lifespan.
• Understand why "just-right" sizing is crucial for maintaining ideal indoor temperatures, humidity control, and system durability.

Accurate HVAC load calculations aren't just about numbers—they directly impact your comfort, your energy bills, and the longevity of your HVAC system.
