Houses in Compton, measured the same way as the warehouses
Single-storey post-war stock with the original ducts in an attic that reaches well over 130°F on a summer afternoon, additions nobody sized anything for, and garage conversions cooled by whatever was to hand.
Everything found, everything measured, nothing sold on the spot
We locate every piece of equipment, photograph the rating plates and record the model and serial numbers. Then the readings: static pressure across the filter and the coil, airflow, refrigerant charge against the manufacturer’s target for that model at that condition, temperature split, and humidity in the room with the complaint rather than in the hallway.
If there is a gas furnace or a gas water heater in the same space, a combustion analysis and a heat exchanger inspection happen on that first visit whatever you called about, and if there is no working carbon monoxide alarm we will fit one.
You keep the readings. They commit you to nothing, and they are what makes a second opinion possible — ours or anybody else’s.
Four findings that account for most of it
The ducts are in the attic and the attic is an oven
On a hot afternoon an uninsulated attic in this part of Los Angeles County is far hotter than the outside air, and every foot of duct running through it is losing cooling before the air reaches the room. Sealing the joints and insulating the runs is unglamorous work that regularly does more for a house than replacing the equipment would.
The system is bigger than the house needs
Oversizing is the most common fault we measure and the least often mentioned. A unit that is too large cools quickly, shuts off, and never runs long enough to take moisture out of the air — so the house is cold and clammy and never feels right. A room-by-room load calculation settles it, and it is an afternoon’s work.
One return, five rooms, all the doors shut
Air that goes into a room has to get back out. A single central return with closed bedroom doors forces the air through the gap under the door, pressure builds, and the airflow to that room collapses. Transfer grilles or an extra return are cheap and are frequently the whole fix.
The garage conversion was never part of the plan
A converted garage or a rear addition tacked onto a duct system sized for the original house will always lose. It is usually not a fault in the equipment and it does not get better with a larger unit. A ductless head sized for that room, or a properly extended and rebalanced duct run, is the honest answer.
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 right.
- Load calculation and replacement
Room by room, on the house as it stands now rather than on the size of the unit coming out.
- Attic duct sealing and insulation
Leakage measured, joints sealed, runs insulated, registers balanced against a target rather than by feel.
- Ductless for additions and conversions
Sized for the room it serves, with the line set routed where it can be serviced and the condensate given a fall it can use.
- Gas appliance safety
Combustion analysis, heat exchanger inspection, flue checked as installed, carbon monoxide alarms fitted where there is none.
- Annual service
The same readings every year on the same sheet, so a slow change is visible before August turns it into an emergency.
Three things we will not do in your house
- Condemn a heat exchanger without showing you why. A cracked heat exchanger is a real reason to shut a furnace down, and it is also the most abused finding in this trade. If we call it, you get the camera image or the combustion reading that supports it, and you are welcome to have somebody else look before you spend anything.
- Recommend replacement on age alone. Age changes the arithmetic on a repair. It is not a fault. An old system that is correctly charged, moves the air it should and passes its safety checks is a working system.
- Use the heat rules to sell you something at home. California’s indoor heat standard is about workplaces. It has nothing to do with your house, and anybody bringing it up on a residential doorstep is selling.
