We install filtration, humidity control and ventilation equipment in Greene 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.
Can a house be too airtight?
It can be too airtight without deliberate ventilation, which is not the same as saying tight houses are bad. A leaky old house ventilates by accident, expensively and unevenly. A tight modern one holds humidity, cooking byproducts and everything else indoors until something removes them on purpose. That is what mechanical fresh air is for, and it is why newer houses sometimes feel stuffy despite being far better built. The answer is controlled ventilation rather than deliberately making the shell leak.
What do UV lights in the ductwork actually do?
Two quite different jobs get sold under one name. A coil light aimed at the evaporator keeps growth off a surface that is wet for half the year, and that one has a straightforward case: it keeps a coil clean and it keeps the musty smell down. An air-stream light is meant to treat organizms as they pass, and air moves quickly, so contact time is short and the benefit is much harder to demonstrate. If someone is quoting UV, ask which of the two it is and what it is being asked to fix.
Everything is static and the wood floors are gapping.
That is winter dryness, and it is a real air quality problem rather than an inconvenience. Cold outdoor air carries almost no moisture, so every air change in January leaves the house drier. Below about 30% relative humidity you get static, cracked skin, irritated airways and gaps opening in flooring and trim. A whole-house humidifier on a humidistat handles it more evenly than portable units. Do not simply run it high: too much moisture in a cold snap condenses on windows and inside exterior walls.
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.
