Multi-Zone Systems: The Good, The Bad, and The Conflicted

Zoning. The concept makes perfect sense, different areas within a location usually have two different attributes:

1). The thermal gain or loss differs between areas inside the same building envelope.

2). The occupants of the space have different comfort levels.

Therefore, the ability to control heating and cooling independently is a very appealing concept. The devil however lies in the details. Traditional unitary systems are designed for generally larger areas. Zoning incorporates the ability to isolate areas of the duct system and control the flow of conditioned air to those areas. One main flaw with this is that while the areas requiring conditioned air may vary, the capacity of the system remains the same. This can become a major issue when you have a system producing 1000-cfm of conditioned air, and one zone requiring only 300-cfm of conditioned air is calling. What do we do?

Are you a Smart Home Addict?

Hello, my name is Matt and I fear that I am an entry-level Smart Home Addict. I’m not full-blown mind you … more of recreational user that can see the eventual descent into hopeless addiction. Now, in full disclosure, none of the above is meant to make light of serious addictions or anyone who suffers from one. Rather, the point I am making is that smart home products start with just one often time and then can quickly lead to many. Now I am not what anyone would consider a “techie” person, despite being a millennial. I do not Facebook, Twitter, Tik-Tok, Instagram, or… Myspace. I know how to use computers and smartphones, but outside of using them professionally, I am not one to be found casually utilizing technology.

Tech Tips: Dual Fuel in Dollar and Cents

Recently I received a phone call from a colleague who had a client proposing a dual fuel HVAC system to a homeowner. This homeowner was both technically capable and very inquisitive. He wanted to accurately quantify the cost difference between heating with a gas furnace versus a heat pump. The question was simple enough, but when I was asked for the answer… I stammered. I did not actually have a straightforward solution. This bothered me a lot, and my mind had two thoughts, which were equally bothersome:

  • “If I cannot explain something clearly, then I myself do not truly understand it.”
  • “In GOD I trust; everyone else must provide data.”

My curiosity had to be satisfied. So, I went digging on the internet… and nothing was clearly quantified. However, I did find the formulas needed to answer my question. So, let’s dive into the topic of gas versus a heat pump and look at some real math on the costs. To start, we have to look at all costs in the same format. I choose to compare everything to natural gas heat and look at this through the cost per BTUH. All utility costs are based on my specific area and are clearly identified so this math could be adjusted based on your utility costs.

Tech Tips: Ductless Logic – What that Wall Mounted Unit is Really Thinking

Ductless units or mini splits – they are the bane of many HVAC technicians. The units themselves are quiet, super-efficient, and work very well. Often, technicians will say something like, “I install a lot of these units and they generally work great, but honestly I have no idea what’s really going on inside those things.” It’s a fair enough statement. Most technicians are accustomed to contactors, relays, capacitors, AC voltage motors, and simple I/O controls. There is nothing simple in appearance about the inner workings of a ductless unit.

For starters, we have the board which is located next to a 2nd board which is then located above a 3rd board. There are no contactors or relays. The only capacitors are built into the control boards. Controls? Yes, we have controls, but not the traditional I/O kind we usually think about. Nope, these things talk back and forth. What are they saying? Who knows!
