Indoor air quality

Cleaner, better balanced air in every room

A thermostat only controls temperature. Dust that never settles, air dry enough to shock you on a doorknob, a basement that smells like a basement: those are air quality problems, and they have specific fixes.

  • Whole home filtration
  • Humidity control both directions
  • Fresh air ventilation
  • Static pressure measured first

What we install

Equipment that treats the whole house

Portable units clean one room while the system keeps circulating everything else. These work at the air handler, so they treat all of it.

Whole home air cleaners

Four and five inch media cabinets and electronic cleaners installed at the air handler, so every cubic foot the system moves gets filtered rather than one room at a time.

Whole home humidifiers

Bypass and steam units tied to the ductwork and controlled by a humidistat. The fix for winter nosebleeds, static shocks and gaps opening in hardwood floors.

Dehumidification

Ducted dehumidifiers for damp basements and humid shoulder seasons when it is too cool to run the air conditioner but the air still feels heavy.

UV and sterilization

UV lamps at the evaporator coil to keep biological growth off the wet surface where it otherwise takes hold, which also protects airflow and efficiency.

Ventilation

Fresh air intakes and energy recovery ventilators for tight, well sealed homes that trap stale air, cooking odors and carbon dioxide.

Duct evaluation

Before we sell you a filter, we look at whether leaky returns are pulling attic, garage or crawlspace air into the system in the first place.

Match the symptom

What the house is telling you

Nearly every air quality complaint traces back to filtration, humidity or ventilation. Usually it is obvious once you know where to look.

Dust settles again a day after cleaning
Leaky return ducts pulling unfiltered air from an attic or crawlspace, or a filter with a bypass gap around the frame
Static shocks, cracked lips, gaps in the floorboards
Winter indoor humidity sitting in the teens. A whole home humidifier holds it in the thirties
Musty smell that gets stronger when the system kicks on
Biological growth on the evaporator coil or in a drain pan that is not clearing properly
Allergy symptoms that are worse indoors than out
A one inch filter passing most of the particulate that actually matters, and nothing capturing it downstream
Stuffy, stale air in a newer or recently sealed home
Not enough outside air exchange. Tight construction needs mechanical ventilation to breathe
One room always damp or always dusty
Airflow imbalance. Often a duct run that is undersized, crushed or disconnected somewhere out of sight
Mechanical room equipment installed by Raber HVAC with accessible isolation valves and tidy copper runs
Accessible valves and labeled runs. Air quality equipment only helps if it can actually be serviced.
How we approach it

Measure, then recommend

Selling an air cleaner into a system with crushed returns and high static pressure does not fix anything. It just adds cost and restriction.

  • Static pressure read on supply and return before any filtration is proposed
  • Return leakage checked, since that is where most unfiltered dust enters
  • Indoor humidity measured in real conditions, not estimated from the weather
  • Blower capacity confirmed to carry whatever we add without choking airflow
  • Equipment matched to the actual complaint rather than a package everyone gets
  • Filter sizes and change intervals written down so upkeep is not a guess
Air quality FAQ

Air quality questions we answer most

If yours is not here, call and ask. We would rather answer it now than have you guess.

Ask us directly

Frequently, yes. The EPA has reported indoor pollutant levels commonly running several times higher than outdoors, and it matters more here because Ohio weather keeps people inside for a large part of the year. The same tight building envelope that lowers your gas bill also holds everything else in.

Service area

Seven counties, one local crew

We are based in Independence and most of our work sits inside a forty minute drive. That is deliberate. A tight radius is what makes same day service possible instead of aspirational.
