Effective IAQ Measurement & Control w/ Haven

In this podcast, Ben from HAVEN IAQ, Kaleb, and Bryan discuss how to control indoor air quality and take effective, meaningful, accurate measurements.

HAVEN is a platform that offers hardware and software delivered to a homeowner through an HVAC professional. HAVEN’s goal is to give its customers a healthier, more comfortable home using IAQ solutions.

The hardware (controls, etc.) works with the HAVEN software to give customers and contractors data about IAQ and the performance of the HVAC equipment. Right now, you may install up to two HAVEN controllers and one monitor per zone to help control equipment and monitor the air content.

Air sampling occurs every hour, whether the HVAC system is running or not. Customers can learn to control their ventilation habits to address acute events (e.g., a spike in humidity from cooking), which only result in short-term IAQ problems. However, contractors can use the air sampling data to develop solutions for chronic events (e.g., constant high humidity).

Solutions, even simple filtration ones, are best left to the contractors to figure out. The integration of most IAQ products requires some degree of design and planning. HAVEN products do NOT provide plug-and-play solutions. While “demand” solutions can introduce outdoor air to prevent a viral problem, you could introduce a moisture problem without proper planning.

Ben, Kaleb, and Bryan also discuss:

HAVEN central air controller
Building relationships with customers
Software integrations with other platforms
Filtration caveats
HAVEN Pro Portal and Personal Use Program
Ease of connecting HAVEN controllers to equipment
“Demand” ventilation, dehumidification, etc.
Importance of airflow
Making IAQ product sales and educating homeowners
IAQ placebos
In-duct monitoring

HVAC School – For Techs, By Techs

Real training for HVAC ( Heating, Ventilation, Air Conditioning and Refrigeration) Technicians. Including recorded tech training, interviews, diagnostics and general conversations about the trade.

In this enlightening episode, we sit down with Mike, a 20-year veteran from DITEK, a leading American manufacturer of surge protection devices based in Largo, Florida. The conversation begins with a brief discussion about recent hurricane impacts in the Tampa Bay area, where DITEK maintains its 65,000-square-foot manufacturing facility. Mike shares how the company, despite facing challenging weather conditions, continued its operations and maintained its commitment to American manufacturing.

The bulk of the discussion centers around surge protection technology and its critical importance in protecting HVAC systems and other electronic equipment. Mike provides an excellent analogy, comparing surge protectors to pressure relief valves for electrical systems. He explains how Metal Oxide Varistors (MOVs) work as semiconductors that create low impedance paths to ground when voltage exceeds certain thresholds. The conversation delves into the evolution of MOV technology, particularly the development of thermally protected MOVs that provide enhanced safety features.

The episode also addresses common misconceptions about surge protection, particularly the belief that surge protectors are primarily for lightning protection. Mike explains that while lightning strikes are a concern, especially in areas like Florida, approximately 65% of surges actually originate from within facilities themselves, often from equipment cycling on and off or other power quality issues. He emphasizes the importance of proper installation, particularly regarding ground connections and lead lengths, noting that every six inches of wire length can add about 100 volts to the clamping voltage of the device.

Key Topics Covered:

DITEK’s history and commitment to American manufacturing
Basic principles of surge protection and how MOVs work
Evolution of MOV technology and thermal protection features
Difference between transient voltage and temporary overvoltage (TOV)
Importance of proper grounding and lead length in surge protection
Cascading surge protection strategy for comprehensive protection
UL testing standards and voltage protection ratings (VPR)
Common misconceptions about surge protection
Impact of aging electrical infrastructure on power quality
Importance of customer support and ethical business practices
Installation best practices for surge protection devices
Relationship between ground resistance and surge protector performance
Types of surge protective devices (SPD) and their classifications
