Houses in Santa Barbara, measured before anything is proposed
Plaster with no cavity, crawl-space air handlers, hillside additions on one ductless head, and a climate mild enough that a badly performing system can go unnoticed for years and then fail in a September heat spell.
An hour and a half, and a sheet of paper at the end of it
We find every piece of equipment, photograph the rating plates and write down the model and serial numbers. Then the readings: static pressure across the filter and the coil, airflow, charge against the manufacturer’s target, temperature split, and humidity in the room that has the complaint rather than in the hallway.
If there is a gas appliance, a combustion analysis and a heat exchanger inspection happen on that first visit regardless of what you called about.
You keep the sheet. It commits you to nothing and it is the thing that makes a second opinion possible — ours or anybody else’s.
Four findings that account for most of it
The system is bigger than the house needs
Oversizing is the most common fault we measure and the least often mentioned. An oversized system reaches the thermostat setpoint quickly, shuts off, and never runs long enough to remove moisture — so the air is cold and clammy and the house never feels right. A room-by-room load calculation takes an afternoon and it is the difference between equipment that works and equipment that merely runs.
One return for five rooms
Air that goes into a room has to get back out. A house with a single central return and closed bedroom doors is asking the system to move air through a gap under a door, and the pressure that builds up cuts the airflow to that room. Adding returns or transfer grilles is cheap, unglamorous and frequently the whole fix.
The ductwork leaks into the crawl space
Flexible duct that has come off a boot, crushed runs behind stored boxes, sections never sealed at the joint. Measured duct leakage on older Santa Barbara houses is routinely a large fraction of the total airflow, which means a meaningful share of what you pay to cool is cooling a crawl space.
The ductless head was asked to do too much
A single wall head will condition the room it is in. It will not condition the room around a corner, whatever the square-footage figure on the box suggested, because it has no way of moving air there. This is a sizing and placement problem rather than a fault, and it is usually solved by a second head rather than by a bigger one.
What we do in houses
- Diagnosis and repair
No cooling, no heat, short cycling, noise, a room that never matches. Measured, costed, and repaired where a repair is the right answer.
- Load calculation and replacement
Room by room, on the house as it is now rather than on the size of the unit coming out. Ducted, ductless or heat pump, chosen from the numbers.
- Duct sealing and rebalancing
Leakage measured, joints sealed, returns and transfer grilles added, registers set against a target airflow.
- Gas furnace safety
Combustion analysis, heat exchanger inspection, flue checked as installed. Carbon monoxide alarms fitted where there is a gas appliance and no working alarm.
- Humidity and ventilation
Coastal fog and closed-up rooms produce real humidity problems. Measured in the affected room, over time, before equipment is suggested.
- Annual service
The same readings every year, on the same sheet, so that a slow change is visible instead of becoming a breakdown.
Three things we will not do in your house
- Condemn a heat exchanger without showing you why. A cracked heat exchanger is a genuine reason to stop using a furnace. It is also the single most abused finding in this trade. If we say it, you get the camera image or the combustion reading that says it, and you are welcome to have somebody else look before you spend anything.
- Recommend a replacement on age alone. Age changes the arithmetic on a repair. It is not a fault. A twenty-year-old system that is correctly charged, moves the air it should and passes its safety checks is a working system.
- Attach a health outcome to a reading. We will measure particulates, humidity and ventilation rates and give you the numbers. What those numbers mean for somebody’s asthma or allergies is a medical question and we will not answer it.
