What an Air Handler Is, and Why It’s Usually Replaced as a Pair

The short version for homeowners who’ve just been told they need one.

An air handler is the indoor unit of a heat pump system. If your home has a heat pump outside and no gas furnace, the cabinet in the basement, closet or attic is the air handler. Inside are the blower that moves air through your ducts, the evaporator coil that heats or cools that air, electric heat strips for backup heat on the coldest nights, a filter rack and a condensate drain. No burner, no gas line.

The coil inside the air handler and the compressor in the outdoor unit are one refrigerant circuit, designed to work together. Manufacturers publish the tested pairings through AHRI, and a matched pair is what the efficiency ratings, the manufacturer’s warranty and the ComEd heat pump discount are all based on. That’s why an air handler is usually replaced together with the heat pump outside. If the outdoor unit is new and the air handler failed on its own, replacing just the indoor unit with a matched model is possible, and we’ll tell you when that’s the smarter spend.

Signs It’s Time to Replace Your Air Handler

Some of these are a repair. Several of them together usually aren’t.

  • It’s 12 to 17 years old. That’s the typical life of an air handler and heat pump in northern Illinois. Past 15, big repairs rarely pay off.
  • The evaporator coil is leaking. Coils corrode from the inside. A coil replacement plus a recharge of R-410A, which is being phased down and getting more expensive every year, is often more than half the cost of a new matched system.
  • The heat strips are carrying the winter. If the outdoor unit can’t keep up and the strips run for hours, your electric bill shows it. A cold-climate inverter heat pump with a matched air handler fixes the cause.
  • You’ve had two major repairs in two years. A blower motor last winter and a control board this summer is a pattern, not bad luck.
  • The cabinet is rusting through. Years of condensate and a pan that overflowed a few times take their toll. Rust at the base of the cabinet means the coil and pan aren’t far behind.
  • The outdoor unit is being replaced anyway. A new heat pump on an old, unmatched air handler doesn’t hit its rated efficiency, may void the warranty and doesn’t qualify for the ComEd discount.
  • It still runs on R-22. That refrigerant is no longer produced. A leak on an R-22 system means replacement, not repair.
  • The house has never been comfortable. Humid summers, a cold upstairs, rooms that never keep up. A single-speed air handler that was sized off the old one’s label often is the problem.
  • Your electric bills climb every year. A worn blower, a dirty coil that won’t come clean and heat strips that stage in early all add up.

If only one thing on this list is true, air handler repair is probably the right call, and regular air handler maintenance will push the replacement date out. We’ll tell you either way, in writing, and you can decide without pressure.

Repair or Replace? The Math We Use

Same rule of thumb every honest contractor uses, applied to your equipment.

If the repair would cost more than half of what a new matched system costs, and the equipment is more than 12 years old, replacement is usually the better use of the money. A capacitor or a sequencer on a 14-year-old air handler is an easy repair. A coil on the same unit usually isn’t, and a coil plus a compressor never is.

What Changes With a New Matched System

A replacement isn’t just a newer version of the same thing. Here’s what you actually get.

Efficiency

A real jump in efficiency

A 12-year-old heat pump and air handler were built to a much lower standard than today’s SEER2 and HSPF2 ratings. An Amana S-Series inverter heat pump with a matched variable-speed air handler runs at the speed the house needs instead of full blast and off, which cuts both the cooling and the heating bill.

Winter

Heat that keeps going below zero

Cold-climate inverter heat pumps keep heating well below 0°F, which means the electric heat strips in the air handler run far less. On the old system the strips were doing the work on every cold night. On the new one they’re true backup.

Comfort

Variable-speed airflow

A variable-speed ECM blower ramps up and down with the load. Longer, gentler cycles mean better dehumidification in July, even temperatures room to room and far less noise than a single-speed blower slamming on.

Refrigerant

R-32 instead of R-410A

New systems use R-32, a lower-GWP refrigerant that isn’t subject to the R-410A phase-down. Any future refrigerant service is on a refrigerant that’s staying available and affordable.

Right-sized

Sized to your house, not the old label

We size the new system to the house instead of copying the tonnage off the old unit, and run a Manual J load calculation when it’s needed, requested or required. Many older systems in the Fox Valley were oversized, which is why they short-cycle and leave the house humid.

Protected

Matched pair, full warranty

An AHRI-matched air handler and heat pump carry the manufacturer’s full parts warranty. We register it for you. A mismatched pair can void it.

We install Amana and Daikin equipment, including the Amana S-Series R-32 heat pump line. For the installation process itself, from sizing through commissioning, see air handler installation.

How the Replacement Day Goes

Most air handler and heat pump changeouts are done in a single day.

  1. Before the day. You’ve approved a written quote with the discount on it. We’ve pulled the mechanical permit under our own license where your town requires one. If the electrical circuit for the heat strips needs upgrading, that’s already in the plan.
  2. Morning. We protect the floors, recover the refrigerant from the old system with EPA-certified equipment, disconnect power and remove the old air handler and outdoor unit.
  3. Midday. The new air handler is set in place, leveled and connected to the existing ductwork with new transitions where needed. New line set or flushed existing line set, new condensate drain with a float switch, and the electrical connections for the blower and heat strips.
  4. Afternoon. The outdoor unit goes on its pad, the line set is pressure-tested with nitrogen and evacuated to a deep vacuum, and the charge is set and verified. We commission the system in both modes, set up the thermostat staging and walk you through it.
  5. Cleanup and haul-away. Old equipment, packaging and debris leave with us. The old refrigerant is recovered and handled per EPA rules, not vented.

Many Fox Valley municipalities require a mechanical permit for equipment replacement. We’re municipally licensed in Elgin, Aurora, Bartlett, Huntley and Streamwood, and we file the permit under our own license where it’s required, so the inspection is our responsibility, not yours.

What Air Handler Replacement Costs

How our pricing works, and how the discount changes the number.

We don’t publish a total installed price, because the right number depends on the size of your house, the efficiency tier you choose, whether the electrical circuit or ductwork needs work and where the air handler lives. What we do promise: the quote is free, it’s in writing, it’s the price you pay, and it already has the ComEd discount taken off.

For a qualifying ducted heat pump system, that discount is $900 to $2,000 depending on the efficiency tier and heating capacity, with up to $2,000 on a ducted heat pump of 2.5 heating tons or more. Add a qualifying ENERGY STAR smart thermostat we install and it’s another $75. There’s no application and no waiting for a check; it comes off the invoice. The equipment has to be AHRI-matched and use a refrigerant at or below 700 GWP, which R-32 does. See ComEd instant discounts.

Financing is available, and you can prequalify in about 2 minutes with no impact to your credit score. The discount lowers the amount you need to finance. On-bill financing is another option for some homeowners.

What Every Air Handler Replacement Includes

A new system is only as good as the changeout behind it.

Air Handler Replacement FAQs

What is an air handler and do I have one?

An air handler is the indoor unit of a heat pump system. If you have a heat pump outside and no gas furnace, the cabinet in your basement, closet or attic is the air handler. It holds the blower, the evaporator coil, electric backup heat strips and the filter.

Do I have to replace the air handler and the heat pump at the same time?

Usually, yes. The indoor coil and the outdoor unit are one refrigerant circuit and are rated as an AHRI-matched pair. Replacing both is what gets you the rated efficiency, the full warranty and the ComEd discount. If the outdoor unit is new, a matched indoor-only replacement is sometimes the right call.

How long does an air handler last?

Air handlers and heat pumps in northern Illinois typically last 12 to 17 years. Regular maintenance helps it reach the upper end of that range.

Should I repair or replace my air handler?

If the repair costs more than half the price of a new matched system and the equipment is over 12 years old, replacement usually makes more sense. A leaking coil on an older unit is the most common reason we recommend replacing. We’ll give you a written price for both.

How much does it cost to replace an air handler in Elgin?

It depends on the size of the home, the efficiency tier, the electrical and duct work needed and where the unit sits, so we don’t publish a single number. Quotes are free, written and include the ComEd discount, which is $900 to $2,000 on a qualifying ducted heat pump system.

How much is the ComEd heat pump discount?

Qualifying ducted heat pump systems get $900 to $2,000 off depending on efficiency tier and heating capacity, up to $2,000 on 2.5 heating tons or more. A qualifying ENERGY STAR smart thermostat we install adds $75. It comes straight off the invoice with no application.

I live in St. Charles. Can I get the ComEd discount?

No. St. Charles, Geneva and Batavia run their own municipal electric utilities, so ComEd discounts aren’t available there. Everything else about the installation is the same, and financing is still available.

How long does an air handler replacement take?

Most air handler and heat pump changeouts are done in a single day. Attic installations or jobs that need a new electrical circuit for the heat strips can take a little longer.

Will a new system lower my electric bill?

Usually, and often noticeably. A cold-climate inverter heat pump with a matched variable-speed air handler runs at partial speed most of the time and keeps heating well below zero, so the electric heat strips run far less than they did on the old system.

What happens to my old air handler and refrigerant?

We recover the refrigerant with EPA-certified equipment before removing anything, then haul the old air handler and outdoor unit away. Nothing is vented and nothing is left for you to dispose of.

Do I need a permit to replace an air handler?

Many Fox Valley municipalities require a mechanical permit for equipment replacement. We file it under our own license where required and handle the inspection.

Can I keep my old thermostat?

Often, but a new inverter heat pump works best with a thermostat that can stage it and manage the backup heat correctly. A qualifying ENERGY STAR smart thermostat we install also adds $75 to the ComEd discount.

Does the new air handler still have electric heat strips?

Yes. They’re the backup and defrost heat. On a cold-climate inverter heat pump they run far less than on an older system, because the heat pump keeps heating well below 0°F on its own.

Can I finance a new air handler and heat pump?

Yes. You can prequalify in about 2 minutes with no impact to your credit score, and the ComEd discount lowers the amount you finance.

Do you replace air handlers you didn’t install?

Yes. We replace air handlers and heat pumps of any brand with Amana or Daikin equipment, and we repair and maintain all major brands.

What if I want a gas furnace instead of an air handler?

If your home has gas service, a heat pump paired with a high-efficiency gas furnace is an option. The furnace acts as the backup heat instead of electric strips, and the ComEd and Nicor Gas discounts each apply to their own equipment.
