Series: Pro Training – Non Disposable A/C Units

Pro Training Blog Series

I don’t know about you, but I can say comfortably that I do not find myself in the position of having thousands of dollars I want to dispose of. If you find yourself in a different position, please contact me and I will be happy to help you relieve yourself of those burdensome funds. I am using that statement because I know we can all never agree on the exact “average” cost of a Ductless AC installation, but I feel confident we can all agree that the number is over $1000. My point being that the price point means I am not interested in just “throwing it away” at the first sign of trouble. These machines or appliances are not disposable. They can be maintained, and they can be repaired. However, both of those concepts must begin with us doing something that many of us feel uncomfortable with … opening the machine up.

Tech Tip: Slime Time in Summertime

A common service call that arrives in the latter days of summer is a clogged drain line. It is par for the course in the Southeastern United States; we have warm temperatures combined with high humidity. Air conditioning systems work to address both the temperature of the home (sensible heat) as well as the humidity of the home (latent heat). As the HVAC system runs it absorbs both heat and humidity from the home into the evaporator section of the unit. The heat is transferred outside via the refrigerant lines and superheated refrigerant while the humidity is transferred outside the home via the HVAC system drain line.

Slime in a drain is a universal problem. It occurs in shower drains, sink drains, and even appliance drains.  There are many variables that can increase the likelihood and frequency in slime forming in the HVAC drain system. However, two key ingredients are always present: food and moisture. Food is provided by dust or dirt that manages to get into the HVAC system. This dust and/or dirt will contain some organic matter which will serve as a food source. This will combine with already present moisture from normal cooling operations and provide a moist environment with a food source. The result will be a slimy gunk that will easily clog the HVAC drain line. The drain lines in an HVAC system are not under any pressure, therefore it does not take a large amount of resistance to block the drainage of condensate.

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: 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!
