Choose us for indoor air quality service from a team that’s served the Valley since 1969.

Signs You Have Poor Indoor Air Quality

Wally Falke’s can improve indoor air quality with whole-home filtration, purification, ventilation, and humidity control.

The EPA reports that indoor air can be two to five times more polluted than the air outside. Modern Central Valley homes are sealed tight for energy efficiency, which is good for your bill but potentially bad for your air. If any of these signs sound familiar, your indoor air is worth a closer look:

  • Allergies or congestion that flare up inside your own home, or first thing in the morning
  • Dust that comes back within a day or two of cleaning
  • Stuffy, stale air, or rooms that never quite feel fresh
  • Lingering odors from cooking, pets, cleaning products, or new furniture
  • Dry air in winter: static shocks, dry skin, cracked wood, scratchy throats
  • A musty smell when the AC or heat kicks on (often mold on the coil)
  • Symptoms that get noticeably worse during wildfire smoke or harvest dust season

Whole-Home Air Quality Solutions in the Central Valley

Different air quality problems require different tools. Wally Falke’s starts by finding out what’s actually in your air, then recommends only what moves the needle for your home.

  • Whole-home air cleaners and filtration — these replace the thin one-inch filter in your furnace or air handler with a deep media or electronic cabinet, typically MERV 13 or higher, to capture dust, pollen, dander, wildfire smoke, and mold spores.
  • UV germicidal lamps — mounted at the indoor coil, UV-C light kills the mold and bacteria that love to grow on a wet cooling coil through the Valley’s long cooling season.
  • Whole-home ventilators  — opening a window during a smoke event or a 105-degree afternoon isn’t practical. A ventilator swaps stale indoor air for filtered fresh air and recovers the heating or cooling energy in the process.
  • Whole-home humidifiers — our winters are dry. The goal is balanced humidity in the 30 to 50 percent range, which most local homes drop below in winter.

Seal it in, the envelope matters too: Air sealing, duct sealing, and insulation cut down the raw, unfiltered air pulled into your home. If that’s part of your problem, we’ll point you to our home energy work.

Air Cleaners

Allergy sufferers rejoice!

Whole house air cleaners replace the thin filters that come with a furnace or air handler. These advanced air cleaners can capture microscopic particles including dust, allergens, chemicals leeched out from paints and furniture, mold, bacteria, and more.

UV Lamps

Sanitize all your home's surfaces.

UV Lamps Ultraviolet air purifiers kill airborne and surface mold and bacteria. They are effective mounted in ducting near your HVAC system, as well as the indoor coil to kill the mold that loves to grow during the cooling season.

Humidifiers

No more dry air indoors.

Believe it or not, proper humidity does a lot for your indoor comfort. Dry air is uncomfortable. Humid air feels muggy and hot. Both scenarios cost you money because you end up running the heating and air more. Whole house humidification control will transform your comfort and lower utility bills.

Ventilators

Good air in. Bad air out!

Opening the windows in your home to let in the fresh breeze may sound like a good idea, but it’s not practical. It’s also not efficient from an energy perspective. A ventilator can exchange fresh air from outside for stale indoor air, and transfer heat energy during the process

What Indoor Air Quality Upgrades Cost

Pricing depends on your home’s size, ductwork, and which solution fits your problem, so the only accurate number is one based on your system. As a rough guide, here’s what Central Valley homeowners typically see installed:

  • Whole-home air cleaner / high-MERV filtration: about $500 to $1,500 for most cabinets; premium multi-stage systems can run higher
  • UV germicidal lamp: about $500 to $1,200 for a single-lamp system
  • Whole-home humidifier: about $600 to $1,500 installed
  • Ventilators (fresh-air exchange): quoted per home, based on layout and ducting

How we assess your air: Our technicians will look at your symptoms, your system, and what’s measurable in your air, then recommending the smallest fix that solves the problem. Many air-quality checks are included with a service visit, and we always give a free second opinion if another company has quoted you a big IAQ package.

The Central Valley Has Some of the Toughest Air in the Country

Stanislaus County ranks among the 20 worst counties in the United States for year-round fine-particle pollution (PM2.5), and it fails every air-quality measure the American Lung Association tracks in its State of the Air report. A few reasons our air is genuinely harder on a home than most:

  • The Valley traps its own air. We sit in a bowl ringed by mountains. In winter, temperature inversions form a lid a few hundred feet up and hold particulates over the valley floor for days at a time. There’s nowhere for it to go.
  • Dust is constant. The San Joaquin Valley Air Pollution Control District points to agricultural operations and windblown dust as two of the Valley’s largest particulate sources. That fine dust works its way indoors and recirculates through your HVAC system.
  • Smoke is now a season. Central Valley residents have averaged more than 40 days a year of unhealthy air since 2010. During wildfire smoke events, studies have measured indoor fine-particle levels nearly tripling. A tight home helps, but only good filtration removes what gets in.
  • Valley dust carries more than dirt. The Central Valley reports most of California’s Valley fever cases, which spread through airborne soil dust. Reducing the dust circulating indoors is one more reason whole-home filtration is worth it here.

We’ve worked on Central Valley homes since 1969 from our shop in Turlock, so we build air quality plans around these conditions, not a generic checklist. From Turlock we serve Modesto, Merced, Manteca, Ceres, Oakdale, Ripon, Riverbank, Patterson, and Los Banos.

Indoor Air Quality FAQs

Common signs are allergies or congestion that flare up indoors, dust that returns quickly after cleaning, stale or stuffy air, and musty odors when the system runs. The only way to know for sure is to measure it. We can assess your home’s air and tell you whether equipment is actually warranted.

There isn’t a single best one, because different problems need different tools. For Central Valley dust and smoke, a high-efficiency whole-home air cleaner usually does the most good. UV lamps target coil mold, ventilators handle stale air, and humidifiers handle dry winters. We recommend based on what your home needs, not a one-size box.

Yes, when they’re the right kind. Whole-home high-MERV filtration removes the fine particles in wildfire smoke as your HVAC system circulates air. During smoke events, indoor fine-particle levels can climb sharply even in a closed-up home, so filtration plus keeping windows shut is the practical defense here.

Good filtration reduces the airborne dust, pollen, and dander circulating through your home, which many allergy sufferers notice. It’s not a medical treatment, but cutting the particulate load indoors is one of the most effective comfort upgrades available in our dusty climate.

Most whole-home air cleaners, UV lamps, and humidifiers install in about two to four hours, because they integrate with your existing furnace or air handler. Bigger jobs, like adding a ventilator or changing ductwork, take longer. We give you a clear timeline before we start any work.

Most Valley homes benefit from a humidifier, not a dehumidifier. Our winters are dry, which causes static, cracked wood, and dry skin, and balanced humidity also lets your home feel comfortable at a lower thermostat setting. Very few homes here need a whole-home dehumidifier, but we’ll tell you if your specific home is the exception.

Most whole-home air cleaners run about $500 to $1,500 installed, with premium multi-stage systems higher. UV lamps and humidifiers typically fall in the $500 to $1,500 range. Your actual cost depends on your home and ductwork, so we quote it after we see your system.

Higher MERV captures smaller particles, but too restrictive a filter can strain some systems. The right rating balances filtration with your equipment’s airflow, often around MERV 13 for a whole-home cabinet.
