Which one is yours

Which condo system do you have?

Open the closet, look at the outside wall, read the label. Each of these looks different and prices differently, and each price is the span of what we’ve sold that system for, installed. If yours is an ordinary heat pump or furnace and AC, with the outdoor unit on a pad, it’s priced like a house: heat pump replacement.

MagicPak

One cabinet in a closet on an outside wall, with a metal louver on the outside of the building right behind it. There’s no outdoor unit anywhere: the heat (gas or electric), the AC and the blower all live in that one box.

  • Replaced with us$8,500 to $13,400or $142/mo at 0% APR for 60 months

Where we see them: garden condos and mid-rises. Most of the MagicPaks we replace are in Alexandria and Falls Church.

How old is yours? The rating plate on the front panel dates it: the second pair of digits in the serial number is the year, so serial 8409C12345 was built in 2009. Source: MagicPak FAQs.

First Co through-the-wall system

Two pieces. A condenser set in a sleeve through the outside wall (you see its grille on the balcony or under a window), or sometimes up on the roof, and an air handler recessed into a hallway wall or a closet behind a panel or a louvered door. Look for First Co on the air handler’s label.

  • Replaced with us$7,900 to $12,500or $132/mo at 0% APR for 60 months

Where we see them: garden condos and mid-rises in Arlington, Alexandria, Fairfax and Reston. It’s the condo system we replace most.

Size: most are 1.5 to 3 tons, and 2 tons is the one we see most.

Hydro-air: heat from the water heater

An air handler with a hot water coil inside and two pipes running to it from your gas water heater. The water heater does both jobs, hot showers and the heat, and an outdoor AC does the cooling. First Co sells these as Aquatherm.

  • Replaced with us$11,000 to $14,000or $183/mo at 0% APR for 60 months

Where we see them: townhouse-style and garden condos with a gas water heater in the HVAC closet. Ours have been in Woodbridge, Fairfax, Falls Church and Sterling.

Worth knowing: First Co says a water heater that also heats the home generally needs more gallons and a bigger burner than one that only feeds the taps. Source: First Co, Aquatherm.

Water source heat pump

A cabinet in a closet or above a ceiling panel with water pipes or braided hoses going into it, and no outdoor unit at all. It heats and cools by trading heat with a water loop the whole building shares.

  • Replaced with us$9,100 to $10,300or $152/mo at 0% APR for 60 months

Where we see them: high-rises and mid-rises. More of ours in Arlington than anywhere.

Swapping one means the building closes the water to your unit for the day, so the date gets set with the management office.

PTAC: one room, one box

A single box under a window or low on an outside wall, with its controls on top and a grille outside. It heats and cools that one room and nothing else.

  • Replaced with us, per unit$2,600 to $4,400or $43/mo at 0% APR for 60 months

Measure the sleeve: Replacement PTACs are made to fit the standard 42 by 16 inch wall sleeve, and an old outside grille can stay only if its airflow pattern suits the new unit. Source: GE Appliances, Zoneline buying tips.

Priced per unit. Two rooms means two units.

Fan coil or air handler only

The cabinet in the closet or ceiling is the half that’s failing (a rusted drain pan, a tired blower, a leaking coil), and the outdoor unit or the building’s water is fine. Then only that half gets replaced.

  • Replaced with us$4,500 to $5,100or $75/mo at 0% APR for 60 months

When it works: a hydronic fan coil on the building’s hot water is a clean swap on its own. Behind a refrigerant condenser, it only makes sense when the condenser is young enough and built for the same refrigerant as the new air handler.

Monthly figures: 60mo @ 0% APR on each starting price, the whole price financed, on approved credit. Longer plans lower the payment and cost more in total. The lender sets the final terms. How financing works

Who pays for what

Who owns your condo’s system, and who pays to replace it

Usually you. Virginia’s Condominium Act sets the defaults below, and your condo’s declaration can change any of them.

Parts that serve only you

Unless your condo’s own documents say otherwise, Virginia law makes the part of any duct, pipe or piece of equipment that serves only your unit part of your unit, even where it runs partly outside the unit, and the part that serves more than one unit a common element.

Source: Va. Code 55.1-1912(3)

Equipment outside, serving only you

Equipment that serves only your unit but sits outside it, like a condenser on the roof or on your patio, is by default a limited common element assigned to your unit.

Source: Va. Code 55.1-1912(5)

Who maintains and pays

Unless your condo’s documents say otherwise, the owner maintains, repairs and replaces the unit and pays for it, and the association does the same for the common elements. The exception is damage that starts in the common elements, which is the association’s.

Source: Va. Code 55.1-1955(A)

The building’s water loop

In a high-rise, each unit’s water source heat pump trades heat with a water loop the whole building shares, and the building’s own boiler and cooling tower keep that loop in range.

Source: ClimateMaster, South Waterfront high-rise condo case study

Under those defaults, the MagicPak, the First Co pair, the heat pump in your closet and the PTAC serve only your unit, so they’re yours to replace. The building’s water loop and the risers in the walls are the association’s.

The gray zone is a condenser on the roof or a louver in the outside wall. Find the maintenance chart in your declaration or the association’s rules, or ask the management office, before you sign anything.

The building side

What your building needs before install day

A house needs a permit and room in the driveway. A condo also answers to the association and the management office, and sometimes needs the elevator, the roof or the building’s water. Here’s what each one means for your replacement.

The association signs off on anything outside

Virginia law lets you make improvements inside your unit that don’t weaken the structure, unless your condo documents restrict them, but nothing that changes the outside of your unit or the building except as those documents allow. Source: Va. Code 55.1-1931.

Swapping a MagicPak or a through-the-wall unit in the same opening can leave the outside looking the same, but a new louver, a different grille or a condenser in a new spot changes it. Our written price lists the equipment by model number, so you can attach it to the association’s request.

The management office has its own paperwork

Ask the office what it needs from a contractor before work day: insurance paperwork, the hours work is allowed, and whether the elevator or the loading dock needs a reservation for the carry-in and the haul-out.

Rooftop condensers come up by crane

When the outdoor half sits on the roof and there’s no way to carry it up, we bring a crane. We’ve set new condensers on four-story roofs that way, and the crane is its own line on the written price.

The building has to agree to the date and where the crane stands, so that goes on your list for the office.

A water source heat pump needs the building’s water closed

Swapping one means closing the valves where your unit meets the building loop, and in some buildings draining a riser. Ask the office who opens and closes those valves and whether their engineer needs to be there, and the install date gets set around them.

What’s in our price: a new water source heat pump on the building’s loop, in the same closet or ceiling space, with isolation valves and hoses checked and a sound blanket where the closet is next to a bedroom.

The exact old box may not be made anymore

Since January 1, 2025, a new home air conditioner or heat pump system has to run on a refrigerant with a global warming potential of 700 or less, unless every part of it was built before 2025. Source: U.S. EPA, Technology Transitions restrictions by sector.

So the R-410A model in your closet has a successor, not a twin. New systems run on R-454B or R-32, and the indoor and outdoor halves have to be built for the same one. We match the replacement to your opening and your closet, sometimes from a different maker. First Co says every unit in its First-Pak through-the-wall line is compatible with Magic-Pak. Source: First Co, First-Pak.

Sleeves, louvers and the drain over your neighbor

Through-the-wall units live in a sleeve. Replacement PTACs are made to fit the standard 42 by 16 inch wall sleeve, and an old outside grille can stay only if its airflow pattern suits the new unit. A MagicPak’s outside louver attaches to its wall sleeve. Sources: GE Appliances, Zoneline buying tips; MagicPak FAQs.

Inside, a closet unit drips condensate all summer, and in a condo that closet can sit over someone else’s ceiling. Ask about a drain pan and a float switch, which shuts the unit off if the drain clogs, before it can overflow into the unit below. They show up as their own lines on our written prices.

Before you book

Questions for your management office

Call the office before you book and ask these. Send us the answers with your request, and the install date gets set around them.

  1. Do I need the association’s approval, and is there a form? Ask about the outside louver or grille, and the condenser if it’s on the roof.
  2. What does the office need from the contractor? Usually that means insurance paperwork, and whose name goes on it.
  3. Which days and hours can work happen, and how much notice do you need?
  4. Does the elevator or the loading dock need a reservation, and where can the van park?
  5. If the condenser is on the roof: who opens the roof, and can a crane be set up, where, and on what day?
  6. If it’s a water source heat pump or a hydronic fan coil: who closes the valves to my unit, does a riser have to be drained, and does the building engineer need to be there?
  7. Who maintains what? Is there a chart that says whether the condenser, the louver and the sleeve are mine or the association’s?

Same closet, same visit

The water heater too, or just the through-the-wall AC

Two more condo prices: the system and the water heater together, and the through-the-wall AC and its coil on their own.

System plus the water heater in the same closet

$12,000 to $16,000

or $200/mo at 0% APR for 60 months

Condo closets often stack the HVAC and the water heater together. Doing both on one visit means one tear-out, one permit trip and one set of closet repairs.

Through-the-wall AC and coil only

$6,100 to $8,000

or $102/mo at 0% APR for 60 months

Just the through-the-wall AC and the matching coil, when the air handler or furnace in the closet still has years left.

Monthly figures: 60mo @ 0% APR on each starting price, the whole price financed, on approved credit. Longer plans lower the payment and cost more in total. The lender sets the final terms. How financing works

With hydro-air the two are one system: the new water heater gets a side loop and a mixing valve to feed the air handler. The water heater on its own is on our water heater page.

Asked on the phone

Condo HVAC questions, answered straight

How much does it cost to replace a condo HVAC system in Northern Virginia?

With us, a whole condo system runs $7,900 to $14,000 installed: a First Co through-the-wall pair $7,900 to $12,500, a MagicPak $8,500 to $13,400, a water source heat pump $9,100 to $10,300 and hydro-air $11,000 to $14,000. Those are the spans of what we’ve sold, and you get your number in writing before anything is ordered. Smaller jobs cost less: a one-room PTAC, or only the fan coil or air handler. From about $132 a month at 0% APR for 60 months, the whole price financed, on approved credit. How financing works

How much does a MagicPak replacement cost?

$8,500 to $13,400 installed with us, in the same wall opening, with the old one hauled out. The size, gas or electric heat, and any work the louver or sleeve needs move it inside that span. To see how old yours is, find the rating plate on the front panel: the second pair of digits in the serial number is the year it was built. From about $142 a month at 0% APR for 60 months, the whole price financed, on approved credit. How financing works

Can you replace just the air handler in a condo?

Sometimes. A hydronic fan coil on the building’s water, or a closet air handler whose outdoor half is young, can be replaced on its own, $4,500 to $5,100 with us. Behind an older R-410A condenser the two usually get replaced together, because new indoor units are built for the newer refrigerants and have to match the outdoor half. From about $75 a month at 0% APR for 60 months, the whole price financed, on approved credit. How financing works

Does the condo association pay to replace my HVAC?

Usually not. Virginia Code 55.1-1955 sets the default: unless your condo’s documents say otherwise, the owner maintains, repairs and replaces the unit and pays for it, and the association does the same for the common elements. The exception is damage that starts in the common elements, which is the association’s. A system that serves only your unit counts as part of your unit (Virginia Code 55.1-1912), so it’s yours to replace. The association’s side is what serves the building: the water loop, its boiler and cooling tower, the risers. Your declaration or the association’s maintenance chart has the final word, so check it before you sign anything.

Who owns the HVAC in a condo?

By default in Virginia, you own the parts that serve only your unit, even where they run partly outside it, and the parts that serve more than one unit are common elements. Equipment outside your unit that serves only you, like a condenser on the roof or your patio, is a limited common element assigned to your unit (Virginia Code 55.1-1912). Your condo’s declaration can change any of that.

How long does a condo HVAC replacement take?

Our condo replacement quotes are written as one day on site, for two or three installers. The calendar time is everything around that day: ordering the exact equipment, the association’s approval if anything outside changes, the elevator or crane date, and the county’s inspection.

Through-the-wall unit or a mini split: which is better for a condo?

If your sleeve and closet are sound, we’d replace like for like. A new through-the-wall or First Co pair goes into the openings you already have, keeps the ducts to every room, and needs no new holes in the building. A ductless mini split is $7,000 to $10,000 for one zone with us and $11,000 to $15,000 for two, and it needs a spot for the outdoor unit and the association’s OK for the line through the wall. Where a mini split wins: retiring a PTAC, or a building that lets you give up a failing water source heat pump. From about $117 a month at 0% APR for 60 months, the whole price financed, on approved credit. How financing works

Do I need my condo association’s approval to replace my HVAC?

For anything that changes the outside, yes. Virginia law lets you make improvements inside your unit that don’t weaken the structure, unless your condo documents restrict them, but nothing that changes the outside of your unit or the building except as those documents allow. Whether a same-size swap in the same opening needs approval or just notice is up to your association’s rules, so ask the management office before you book.

Can you replace the water heater at the same time?

Yes, and in a shared closet it’s worth doing: one tear-out, one set of closet repairs. The system plus the water heater has run $12,000 to $16,000 with us. With hydro-air, the new water heater gets a side loop and a mixing valve to feed the air handler. From about $200 a month at 0% APR for 60 months, the whole price financed, on approved credit.
