Breathe easier, Hamilton County
We install filtration, humidity control and ventilation equipment in Hamilton 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.
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.
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.
Does cooking really affect indoor air that much?
More than most people expect, particularly with gas. Cooking puts fine particles and combustion byproducts straight into the room, and a range hood that recirculates through a charcoal filter rather than venting outside does very little about it. Use the hood every time and check that it actually vents outdoors. If it does not, opening a window while cooking does more than any purifier will, and it costs nothing.
