HVAC Replacement in an Apartment Building: Budgeting the Capital Cost
On this page
Heating, ventilation and air conditioning (HVAC) equipment is one of the largest predictable capital costs in an apartment building. Equipment ages, parts fail and a whole system may need replacing at once. A sponsor who knows the age and condition of each unit can plan the replacement in the budget instead of finding it in a crisis.
This guide covers how to inspect the equipment, how system types change the cost and how to build the replacement into the capital plan.

What types of HVAC systems do apartment buildings use?
- Individual unit systems. Each unit has its own heat pump, furnace and condenser, or a through-wall unit. Replacement happens one unit at a time, which spreads the cost.
- Central systems. A boiler or chiller serves many units through piping or ducts. Replacement is one large project, with disruption and a bigger budget line.
- Packaged rooftop units. Common on corridor and commercial spaces. They are replaced on the roof, which adds crane or access cost.
How do you inspect the equipment?
- Make a schedule. List each unit or system, its installation date, its type and its nameplate data.
- Check the service records. Look for regular filter changes, coil cleaning and annual service visits.
- Look at the condition. Note corrosion, refrigerant leaks, noise, uneven cooling and short cycling.
- Ask for the last repair history. Frequent compressor or fan repairs point to an early replacement.
- Get a mechanical report. A qualified mechanical engineer or contractor can state the remaining life of each major system.
The property due diligence guide covers the full inspection list, and the capital plan guide explains how replacements are drawn from the reserve.
How do you budget it?
Build a replacement schedule for each system: the year it is due, the cost today, the cost inflated to that year and the funding source. Then compare the total with the reserve in the budget. The gap is the amount the sponsor must add to the reserve, cut from the plan or fund by capital raised.
A hypothetical example
These figures are made up for illustration. Real replacement costs come from bids.
A 48-unit building has individual heat pump systems. The inspection shows 30 systems installed 12 years ago, with an expected life of 15 to 18 years, and 18 systems installed 4 years ago. The made-up replacement cost is $6,500 per unit system today.
| Item | Amount |
|---|---|
| 30 systems due within 5 years, at $6,500 each (today's cost) | $195,000 |
| Inflation to the replacement year at 3% a year (made-up rate) | about $225,000 |
| Annual reserve to fund this over 5 years | about $45,000 a year |
The sponsor adds about $45,000 a year to the capital reserve for five years, or budgets it as a capital project at closing. The plan should also note that the 18 newer systems will come due later in the hold.
What should investors see?
- The inventory of systems, their ages and the expected replacement years.
- The reserve balance and the annual funding amount.
- How replacements are paid for and when they are drawn.
- What happens if a central system fails before its planned replacement.
How DoorRaise fits in
DoorRaise helps sponsors raise equity for apartment buildings with 5 or more units under Rule 506(b) or 506(c). The deal's capital plan shows replacements by year, so investors see the timing and the funding, and the projected returns subtract the reserve. DoorRaise does not inspect equipment or give engineering advice. Setup is $1,500 (non-refundable), and the administration fee is $5,000 a year from closing.

FAQ
How long does HVAC equipment last?
It varies by type, climate, maintenance and use. Get the remaining life from the mechanical report, not a general figure.
Is HVAC replacement a capital expense or a repair?
A replacement of a major system is usually capital. Routine repair and service are usually operating expenses. Ask the CPA to confirm the classification.
Should I replace all systems at once?
Not usually. Staged replacement spreads the cost and keeps the reserve steady. A central system is different, because it is one project.
Does a service contract lower the cost?
It can extend equipment life and catch problems early, but it adds a monthly cost. Count both.
