What indoor air quality equipment can I get?
We measure humidity, particulates and ventilation before recommending anything.
What fits a 1990s or 2000s Mason house?
Almost anything, which is the advantage of this housing stock. There is a real return plenum and a real supply trunk, so a four-inch media filter, a whole-home humidifier, a UV lamp or a ducted dehumidifier all mount without modification. The constraint here is rarely the ductwork. It is deciding which problem is actually being solved, which is why the measurement happens first.
The house feels damp even with the AC running.
Cooling removes moisture only while the coil is cold and air is moving across it. An oversized system satisfies the thermostat in short bursts and never runs long enough to dehumidify, which is how a house ends up cool and clammy. Above about 60% relative humidity you get the conditions for dust mites and mold regardless of how clean the house is. The fix is sometimes a dehumidifier and is often correcting why the system short cycles, so measure the humidity before buying equipment for it.
Would cleaning the ducts fix this?
Occasionally, and less often than it is sold for. Ductwork holds a reservoir of settled dust rather than generating anything, so cleaning helps most where there is a specific reason: construction dust, pest activity, or visible debris blowing from registers. For ordinary air quality complaints, humidity and filtration usually move further. If someone quotes duct cleaning as the answer to an air quality problem without looking inside your ducts first, that is worth questioning.
Is a higher MERV filter always better?
No, and this is the most common way people make things worse while trying to help. A denser filter catches more, and it also restricts more air, and a system designed around a one-inch filter can be starved by a high-MERV one dropped into the same slot. Starved airflow means a furnace running hot and an air conditioner freezing its coil. If you want serious filtration, the answer is a thicker media cabinet with far more surface area, not a denser filter in the existing gap.
What is the difference between CO and CO2 in a house?
Carbon monoxide is the dangerous one and comes from incomplete combustion: furnaces, water heaters, fireplaces, a car in an attached garage. It has no smell and it needs alarms. Carbon dioxide is what people exhale, and while it is not toxic at household levels, a room where it climbs is a room that is not being ventilated, so it is a useful proxy for stale air. Alarms are for the first. The second is a ventilation question rather than a safety one.
