I bought a thermal imaging camera three years ago and it cost me 4,140 dollars. I am a chimney inspector and I told myself the camera would find cracks that the eye could not see. The camera arrived in a hard plastic case and the case had metal latches. I felt like a man with a secret when I carried that case into a customer’s living room.

The camera had a high-resolution sensor and it could detect a temperature difference of 0.03 degrees. I spent hours reading the manual but I only ever used the automatic setting. I wanted the homeowners to see the screen because the screen was full of purple and orange colors. The colors looked like science and the science looked like authority.

I did not need the 4,140-dollar camera to see a cracked flue tile. I needed a flashlight and a mirror and a steady hand. I bought the camera because I wanted to own the capability of a forensic engineer. I wanted to be the man who owned the best tool in the county. I was wrong to buy it and the camera now sits in my truck and the battery is usually dead.

The 81 Million Keystroke Promise

I spent this morning cleaning coffee grounds from my keyboard. I knocked the cup over and the grounds fell into the gaps between the keys. I had to pop the keys off with a flathead screwdriver and the plastic made a snapping sound. My keyboard is a mechanical one and it has programmable macros and RGB lighting. I do not know how to program the macros and I keep the lights turned off.

I bought the keyboard because it was rated for 81 million keystrokes and I liked the weight of the aluminum frame. I am a man who cleans chimneys and I write reports on a screen and I do not need a keyboard built for a professional gamer. I own the capacity for high-speed input but I hunt and peck with two fingers.

I stared at the coffee grounds and I realized I was doing it again. I was surrounding myself with systems I did not understand so that I could feel prepared for a life I do not lead.

The Multi-Zone Illusion

I visited a house in the hills last week and the owner gave me a tour. Her name was Sarah and she was proud of her home. She showed me the kitchen and the stone counters were cold. She showed me the HVAC system and it was a multi-zone setup with six indoor heads. The outdoor compressor was a massive white box and it sat on a concrete pad.

I asked her how often she used the library. She said she had not been in the library for three months. I asked her how she adjusted the humidity in the guest wing. She looked at the glass controller and her hand hovered near the buttons but she did not touch them. She said she leaves it on the default setting because the manual is too long.

Sarah owned a system that could manage a small hotel and she lived in the house alone. She paid for the engineering and she paid for the installation and she paid for the prestige of the brand name. She did not have comfort. She had a display of potential comfort.

The rooms were too cold because the units were too large for the spaces and they cycled on and off too quickly. The air was damp because the compressors did not run long enough to pull the moisture out. She stood in the hallway and she looked at the glowing blue screen and she looked like a person who was afraid of her own house.

I used to believe that more power was always better. I thought a 36,000 BTU unit was better than a 12,000 BTU unit because the number was higher. I was wrong about the math and I was wrong about the physics. A system that is too large will short-cycle and the motor will burn out and the rooms will feel like a swamp.

I told a customer once that he should buy the biggest unit he could afford because a safety margin was a good thing to have. I was wrong and I watched that unit fail in four years. The customer spent more money on the purchase and he spent more money on the electricity and he spent more money on the replacement. He owned the capability to cool a warehouse but he only had a bedroom and the bedroom was never comfortable.

We frame this kind of ownership as sophistication but it is a form of waste. We buy the multi-zone system with the smartphone app and the motion sensors and we do not want to talk to our walls. We keep the system because it serves as evidence of our status. It is a marker of what we can afford to ignore.

We hold onto the unused complexity because the alternative is to admit we over-bought. To admit we over-bought is to admit we did not know what we were doing. The industry likes this confusion. The market is full of vague labels and copy-paste specifications and good-better-best tiers.

Most people choose the “best” because they do not want to feel like they are settling for less. They buy the unit with the highest BTU rating because they think it is a shield against the heat of the summer. They do not have an advisor to tell them that the shield is too heavy to carry.

They need a system that matches the real space and the real load and the real way they live their lives. I found that MiniSplitsforLess understood this distinction. They do not push the biggest unit and they do not hide behind jargon. They look at the rooms and they look at the installation realities and they provide what is required.

The Theater of Technology

I cleaned the last of the coffee grounds from the keyboard and I snapped the keys back into place. The keyboard worked but it was still more keyboard than I would ever use. I thought about the 4,140-dollar camera in my truck. I thought about Sarah and her glowing blue controllers.

“

The display of capacity outlives any function it ever had. We think the tool makes the craftsman and the system makes the home.

But the craftsman is the man who knows his tool and the home is the place where the owner is at peace. A multi-zone system is a beautiful thing when it is sized correctly. It allows a family to sleep in cool rooms while the rest of the house stays still. It saves energy and it provides a quiet hum that you can forget.

But when you add zones you do not need, you add points of failure. You add line sets that can leak and flare joints that can crack and circuit boards that can fry. You add a maintenance burden that grows with every extra BTU. You are not buying a better life. You are buying a longer list of things to worry about in the middle of the night.

I told Sarah she should turn off the guest wing units. I told her she should set the master suite to a steady temperature and leave it alone. I told her the humidity stayed in the air because the machine was too strong for the room. She looked relieved when I said it. She did not want to be a forensic engineer or an HVAC technician. She wanted to read her book in a chair without feeling a draft.

The wreath covers the sensor and the sensor measures a house that does not exist.

We should buy what we use and we should use what we buy. There is a quiet dignity in a single-zone system that works perfectly every day. There is a pride in knowing exactly how your heater works and why it is the size that it is. We do not need to display our sophistication through the complexity of our vents. The rest is just a case with metal latches that stays in the truck.

I took my mechanical keyboard and I put it in a drawer. I bought a simple keyboard with no lights and no macros. It has a cord and it has keys and it stays clean. I feel better when I type on it. I do not feel like I am failing to live up to the potential of my hardware. I am just a man writing a report.

I will keep the thermal camera because I already paid for it but I will not bring it inside the next house. I will bring my flashlight and I will bring my mirror. I will look at the chimney with my own eyes and I will tell the truth about what I see.

The truth does not require a high-resolution sensor and it does not need to be purple or orange. It just needs to be right.
