Woods Brothers Consulting has partnered with Mosio of San Francisco, CA. The goal is to change the way HVAC contractors communicate with their technicians out in the field. At WBC, our interests have expanded from energy conservation into work force efficiency. The old adage “Time is Money” is as true today as it always has been.
Mosio’s web-based, two way text software program has found success in in other industries. It appears to be a perfect fit for the HVAC industry as well.
What Does Two Way Texting Software Mean?
HVAC technicians out in the field can use their cell phones to text back and forth to a computer at a central dispatch location. Without additional software or equipment, dispatch can easily and concurrently manage multiple techs out in the field.
A dispatch person may communicate quickly, accurately and efficiently. They may document, log and even analyze response times, send out pre-written responses to commonly asked questions, or links to Google maps. In general, they stay one step ahead of their techs to eliminate down time and indecision.
How Does It Work?
That’s it in a nutshell. The cost is minimal(plans start at $49.00 per month) and will soon pay for itself in time savings alone.

Humidity is the amount of moisture in the air. This will vary based on air temperature. Warmer air will hold more moisture. This is the reason why humidifiers are needed in residential housing. We start with cold/dry outside air that will infiltrate the home. The heating system will warm the air up, which does not add or remove any moisture. Now this warm dry air is absorbing whatever moisture it comes in contact with inside the home. In order to stabilize the moisture level in the home we must add moisture to the air to keep infiltrating outside dry air from absorbing all the moisture from materials in the homes.
There are health benefits to avoiding low RH levels that include dry skin, bloody noses, repiratory issues, sinus congestion…… Target RH levels for healthy environments would be between 40-60% as outlined in the chart below. Lastly one can eliminate static electricity at levels above 35% RH. Taking all of these things into consideration a residence should use a target RH of 40-50% in the home.
Comfort is the most noticeable benefit from proper indoor humidity. Few people realize that dry air feels cool to the skin. The reason is that people will lose heat energy to the surrounding ambient air. When the human body at 98.6°F comes in contact with room air at 75°F the air takes the heat from the body and will leave one feeling cooler. This action is called sensible heat transfer. However latent heat transfer takes place when moisture on the surface of the skin evaporates. The heat required for evaporation is also taken from your body, cooling you further. Sometimes you feel colder, even with the thermostat turned up.
Dry air makes you feel colder than the actual thermostat setting because the moisture evaporating from your skin has a cooling effect. A humidifier can help make the air feel warmer and more comfortable, thus allowing you to lower the set point on your thermostat and saving energy.

Each owner who has spent millions of dollars on a new or refurbished building has every right to expect that the mechanical systems will keep tenants comfortable, while delivering every BTU and saving every kilowatt hour possible. Commissiong agents make sure it really does happen that way. From fixing glitches and tuning existing HVAC systems to providing new systems that deliver the promised results, building commissiong agents are focused on performance. Geremy Wolff and his team of HVAC experts know what’s at stake. Wolff manages the commissioning team for McKinstry, a Seattle design-build and service firm that specializes in mechanical systems and green building technology. It’s their job to prove that the state-of-the-art mechanical systems McKinstry has designed are delivering the energy-efficient performance owners and tenants expect. In existing facilities, they do retro-commissioning or building optimization to diagnose and fix problems in system operations and performance. Commissioning verifies performance “Our commissioning group was born as a support mechanism for our design-build construction group,” Wolff said. . . Read the Rest of the article from Fluke.com HERE.
One of the more common questions I am asked in regards to forced air zoning is, “How does a bypass damper work with a variable speed blower?”
The following is a guest post from EWC Controls chief engineer John Brown. John brings to the discussion four decades of experience designing, testing and manufacturing zoning components. Here John gives an overview of the technological developments with zoning and the integration of variable speed blower motors into the system.
The Zoning and Variable Speed Solution
“I can’t install a zoning system with a residential variable speed air handler or variable speed furnace.”
Never Leave Out the Bypass Damper
“I will no longer need a by-pass damper when I install a variable speed furnace and a conventional zone control system.”
Bypass Dampers and Poorly Sized and Designed Ductwork
Why spend money to condition the air, and then dump it where nobody benefits from it?
The more advanced and costly zone control systems do provide an external pulse width modulation (PWM) or 4-20 ma output signal, to the air handler’s integrated motor control. These zone systems can control and modulate the PWM output, in direct response to the number of zones that are demanding conditioned air, and the pre-programmed CFM requirements of each zone. These systems may not require a bypass damper but they are very unforgiving with poor duct design and layout. These systems could probably benefit from a bypass damper, just in case.

It seems that everywhere I go people complain about wasted tax dollars. Well, here’s your chance to help a government program work, and work for you.
The state of Missouri has launched the Energize Missouri Homes: Home Upgrade and Geothermal Program. Look at the Missouri Department of Natural Resources for the full details. Here is a summary of the program according the the DOE state energy incentive program website dsireusa.org.
Funded by the 2009 American Reinvestment and Recovery Act (ARRA), the Energize Missouri Homes initiative provides single family residences with funding for the Homeowner Upgrades and Geothermal program, which provides homeowners with rebates up to $17,000. In order to participate in the HUG program homeowners should contact their local state-appointed program aggregator directly to schedule an energy audit.
A full home energy audit will be scheduled and conducted by an Energize Missouri Homes (EMH) qualified auditor. Missourian homeowners that choose to participate in the HUG program and that would also like to qualify for state and federal tax incentives should choose an auditor that is both a EMH qualified auditor and a DNR certified auditor. Visit the directory of qualified energy auditors for more information. Upon completion of the audit, the aggregator will provide each homeowner with a list of recommended energy efficiency upgrades (and associated energy savings). It is then up to the homeowner to choose which upgrades to pursue.
- Homeowners that implement upgrades achieving a 15% energy savings will qualify for reimbursement of their energy audit (a $500 value) and a rebate of 50% (up to $2,000) for energy efficiency upgrades.
- Those that install energy upgrades leading to a 25% energy savings unlock a 70% rebate, up to $7,000.
- In addition to energy efficient upgrades, homeowners may choose to install a geothermal ground pump. Those that do will be eligible for a 50% rebate, up to $10,000.
- It is possible to pair the energy efficiency and geothermal rebates for a total rebate value of up to $17,000.
Okay, if you are keeping score, that is a 70% rebate on all kinds of appliances and upgrades. Not just HVAC.
You are an HVAC contractor looking to get on that listed of qualified participants?
What are the requirements to become an Energize Missouri Homes qualified auditor?
Auditors wishing to participate in the Energize Missouri Homes training program must be included in the Missouri Department of Natural Resources’ Missouri Certified Home Energy Auditor Directory or be certified through a program approved by the department. To become qualified, eligible auditors must participate in a one-day training program, complete an in-class assessment and submit a field assessment within 15 days of attending the training session.
What is an approved training session?
• Building Performance Institute (BPI) as a Certified Building Analyst.
• Residental Energy Network (RESNET) as a Certified Rater.
• OR certification through other DNR programs.

When you hear the company name Philips, you may think of TVs or other electronics. Philips is a Dutch company founded in 1891, and today is widely recognized as the world’s leader in light bulb manufacturing.
In fact, Philips manufactures the majority of the UVC bulbs sold as components of air disinfection products to the HVAC industry. When I first began selling and educating people on the benefits of UVC disinfection, I had to do a lot of convincing. Fast forward eight years, and there aren’t too many people who are not aware of the benefits of UV lights for coil irradiation and/or airstream disinfection. Now, due to wildly differing claims from the myriad of manufacturers, there is a general misunderstanding of which products are the most effective.
Fact is, any system relying on UVC to disinfect is using the same 254 nanometer wavelength producing bulb. And more often than not, the bulb is manufactured by Philips.
So, despite the differences in the claims of the companies who incorporate a Philips UV bulb, at the core it is essentially utilizing the same technology. . .let’s let Philips explain the science behind the 254 nanometer UV bulb.
