Whole-Home Air Purifier Service

Whole-Home Air Purifier Repair in Elgin & the Fox Valley

Dust is back on the furniture, the furnace whistles at the filter cabinet, or the old electronic air cleaner snaps and does nothing. Whole-home air purifiers have few moving parts, so most problems come down to the filter, the cabinet seal or the airflow through it. We diagnose and repair AprilAire and every other brand, and we measure static pressure on every call.

Signs Your Air Purifier Needs Repair

A media air cleaner rarely fails loudly. It just quietly stops cleaning.

  • Dust is back. You installed a media cabinet and the house was cleaner for a year or two. Now it is not. Something is letting air around the filter or the filter is spent.
  • The filter is collapsed or bowed. A filter that has loaded past its life, or a lower-quality replacement, folds under the blower’s pull. Air then rushes through the gap it leaves.
  • Whistling or a rushing sound at the cabinet. Air is squeezing through a gap in the door, the gasket or the transition seams.
  • The cabinet door will not latch or close square. A bent door, a missing gasket or a filter that is the wrong size.
  • The furnace trips its high limit or the AC coil freezes. A filter grade too dense for the blower, or a filter that has loaded and doubled the static pressure.
  • Weak airflow at the registers. Same cause. The filter is choking the system.
  • The filter loads in a few months instead of a year. A dirty duct system, a return leak pulling in basement or attic air, or a house that needs a pre-filter.
  • The electronic air cleaner snaps, arcs or its light is off. Dirty cells, a failed power supply, or a cell that has cracked. Most of these are past repair.
  • Dust streaks on the downstream side of the cabinet. Proof the filter is bypassing. Air is going around it.
  • An odor the carbon filter used to catch is back. Carbon media saturates. It is time for a new 213CBN.

The Most Common Causes We See

Five things account for nearly every air purifier call.

Most common

Collapsed or bypassing filter

A media filter that has gone past its 12-month rating, or an off-brand replacement with a weak frame, bows and collapses under the blower. Air takes the gap. We replace it with the correct AprilAire filter and check the frame fits the cabinet.

Seal

Cabinet door and gasket leaks

The door gasket dries and cracks, the door gets bent when a filter is forced in, or the transition seams were never sealed. Every leak is unfiltered air going straight to the blower. We reseal, replace the gasket or straighten the door.

Airflow

Static pressure too high

A MERV 16 filter in a system that could only carry MERV 11 starves the furnace and freezes the AC coil. So does a filter that has loaded. We measure total external static pressure and set the filter grade or blower speed so the numbers are right.

Old equipment

Electronic air cleaners

Dirty or cracked cells, a dead power supply, a broken airflow switch. Cells can be washed and power supplies replaced when parts exist, but most electronic cleaners we see are better replaced with a media cabinet in the same location.

Wrong part

Wrong size or grade

A 20 by 25 cabinet with a 16 by 25 filter and a gap at the top. A one-inch filter stuffed into a four-inch cabinet. We carry the AprilAire 210, 213, 213CBN and 216 and confirm which one your cabinet and your system need.

Upstream

Dirty ducts and return leaks

A filter that loads in months is telling you the ducts are dirty or the return is pulling in basement air through a leak. We check return static and, where it helps, recommend sealing or duct cleaning.

What to Expect on the Visit

We measure airflow, inspect the cabinet and the filter, and quote before any work.

1. We ask what changed. When the dust came back, when the filter was last changed and with what, whether the furnace has been tripping or the AC icing. Those answers point to filter, seal or airflow.

2. We measure static pressure. Total external static with the filter in, then with it out. The difference tells us whether the filter is choking the system, and the total tells us whether the ductwork has its own problem.

3. We inspect the cabinet. Filter condition and fit, door and gasket, transition seams, and the downstream side for dust streaks that prove bypass. On electronic units, cell condition, the power supply and the indicator.

4. You get a flat price. In writing, before work starts. The repair is quoted flat-rate, and you approve that price before any work. Filters and gaskets are on the truck.

5. We repair and re-measure. New filter or gasket, door corrected, seams sealed, and static pressure measured again with the grade your system can carry. The readings go on your invoice.

6. If the unit is not worth fixing, we say so. A dead electronic air cleaner or an undersized cabinet is usually replaced with an AprilAire 1210. See air purifier installation and replacement.

What Air Purifier Repair Costs

A flat diagnostic fee, then a flat-rate repair price you approve before work starts. During office hours (9 a.m. to 5 p.m., Monday through Friday) the service call is $130; weekday evenings after 5 p.m. it is $180, and nights, weekends and holidays are $260. Each includes 30 minutes of travel and 30 minutes of diagnostics, and parts are extra.

Every air purifier call starts with a flat diagnostic fee that covers the airflow measurement and inspection. The repair is quoted separately, flat-rate, for you to approve before any work. Repairs are flat-rate line items: a filter, a gasket, a door, sealing the transitions, or a blower speed change. You see each price before we start.

Electronic air cleaner repairs depend on parts availability. Where a power supply or cell is still made, we quote it. Where it is not, or where the repair approaches the cost of a media cabinet, we quote the replacement and let you decide.

On the $240 semi-annual maintenance plan we check the media filter at the spring tune-up and replace it at the fall tune-up, and static pressure is measured at every visit, so a loading filter is caught before it collapses. Plan members also get one free business-hours service call a year and 5% off repairs.

Repair or Replace the Air Purifier?

Media cabinets are almost always repaired. Electronic air cleaners usually are not.

Repair a media cabinet when the problem is the filter, the gasket, the door or the seams. Those are inexpensive parts and the cabinet itself lasts as long as the furnace.

Replace when the cabinet is too small for the blower and cannot carry a useful filter grade without choking the system, when an electronic air cleaner’s cells or power supply have failed and parts are gone, or when the unit was never sealed into the return properly. The AprilAire 1210 takes a 20 by 25 inch filter, ships with the MERV 11 210 filter, and accepts the MERV 13 213, the carbon 213CBN and the MERV 16 216. See whole-home air purifier installation and AprilAire air cleaners.

Air Purifier Problems We See in Fox Valley Homes

Basement returns, old electronic cleaners and filters nobody changed.

AprilAire whole-home air purifier

The AprilAire whole-home air purifier. We service AprilAire and every other brand of media and electronic air cleaner.

  • Basement furnaces in 1960s to 2000s split-levels and ranches pull dusty basement air through any gap in the return
  • Electronic air cleaners from those decades are common here and most have not filtered anything in years
  • Furnaces run November through March, so a collapsed filter in December means a whole winter of bypass
  • Humid summers from May through September load filters with pollen and mold spores faster
  • One-inch filter racks were standard and were never sized for today’s blowers, so static pressure runs high
  • A media filter past its 12-month rating is the most common thing we find on a dusty-house call

Owner Jeff Kerley is NCI airflow trained, so every air purifier call includes a static pressure measurement, not a guess. We are an AprilAire Preferred Partner and carry the 210, 213, 213CBN and 216 filters. See AprilAire and our indoor air quality services.

Humidity, Filtration and Moisture Control Together

AprilAire’s Healthy Air approach treats the three things that make indoor air uncomfortable: dust year-round, dry air in winter and damp air in summer. A media air purifier handles the dust. A whole-home humidifier handles winter. A whole-home dehumidifier handles the basement in summer. We install and service all three on your existing furnace or air handler. See AprilAire Healthy Air products.

Keep them working without thinking about it. On the $240 semi-annual maintenance plan we swap the air purifier filter, replace the humidifier water panel and change the dehumidifier filter at your spring and fall tune-ups, with static pressure measured every visit.

Whole-Home Air Purifier Repair FAQs

Why is my house dusty again even with a whole-home air purifier?

Most often the filter has loaded past its life and collapsed, or air is bypassing it through a leaking door, gasket or unsealed seam. We inspect the cabinet and check the downstream side for dust streaks that prove bypass.

Why did my media filter collapse?

It went past its rated life and loaded until the blower’s suction folded it, or it was an off-brand replacement with a weak frame. We replace it with the correct AprilAire filter and confirm the frame fits the cabinet.

Can a filter that is too good hurt my furnace or AC?

Yes. A MERV 16 filter in a system that can only carry MERV 11 raises static pressure enough to trip the furnace high limit or freeze the AC coil. We measure static pressure and set the grade your system can breathe through.

How often should the AprilAire media filter be changed?

AprilAire filters are rated for up to 12 months. Homes with pets, heavy dust or dirty ducts load faster. On the maintenance plan we check it in spring and replace it in fall.

Can you repair my old electronic air cleaner?

Sometimes. Cells can be washed and a power supply replaced when the part still exists. Most electronic cleaners we see are old enough that replacement with a media cabinet in the same location is the better spend, and we will show you both prices.

How much does air purifier repair cost?

A flat diagnostic fee covers the airflow measurement and inspection, and any repair is quoted flat-rate for you to approve before any work. Filters, gaskets, doors and sealing are flat-rate items you see in writing first.

Why does the furnace whistle at the filter cabinet?

Air is squeezing through a gap: a dried gasket, a bent door, a filter that is too small, or a seam that was never sealed. The whistle is unfiltered air. We find the gap and close it.

Do you service air purifiers that aren’t AprilAire?

Yes. We service all major brands of media cabinets and electronic air cleaners. We are an AprilAire Preferred Partner and carry AprilAire filters and parts, and we source parts for other brands.

Which AprilAire filter fits my 1210 cabinet?

The 210 (MERV 11), 213 (MERV 13), 213CBN (MERV 13 with carbon) and 216 (MERV 16) all fit the 1210. Which one you should run depends on your airflow, which we measure before recommending.

Why does my filter load in a few months instead of a year?

Dirty ducts, a return leak pulling in basement or attic air, or a home with heavy dust from pets or renovation. We check return static pressure and can recommend sealing or duct cleaning when it will help.

Is a whistling or leaking cabinet an emergency?

No, but it means you are not getting filtration and the furnace may be pulling in unfiltered basement air. It is worth fixing before heating season when the furnace runs every day.

Do you measure airflow on every air purifier call?

Yes. Total external static pressure with and without the filter tells us whether the filter is choking the system and whether the ductwork has a separate problem. The readings go on your invoice.

Should I replace my air purifier when I replace my furnace?

If the cabinet is undersized or leaking, yes, because the return is rebuilt anyway. A sound 1210 cabinet can usually stay. See furnace replacement and air purifier installation.
