Breathe easier, Butler County
We install filtration, humidity control and ventilation equipment in Butler County, Ohio. We measure humidity, particulates and ventilation before recommending anything. Most calls get handled the same day, and someone answers the emergency line at any hour.
Filtration, purification, and humidity control for allergy season, dry winters, and everything the southwest Ohio air brings inside.

Matched to your air, not a catalog.
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.
Is it worth testing the air, and for what?
Two measurements are cheap and genuinely useful: relative humidity and particulate. A basic hygrometer in a couple of rooms tells you more about your house than most paid assessments, because humidity drives so much of the rest. Beyond that, be careful what you are being sold. Broad contaminant panels tend to produce a list of things present in every house at levels nobody can interpret, and the result is usually a quote rather than an answer.
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.
Our house is new. Why does the air feel worse?
Because it is tight and because it is new, and those are two separate effects. A well-sealed shell holds indoor moisture and cooking byproducts instead of leaking them away, so anything generated indoors stays longer. New materials also off-gas for months: flooring, cabinets, paint, adhesives and furniture. Ventilation is the answer to both, and in a new house that usually means using the mechanical ventilation that is already installed rather than adding equipment.
