Summary answer: If your HVAC system is failing, unsafe, or clearly at the end of its life, replace or repair it before listing. A system that does not heat or cool is a common appraisal and inspection problem, especially for VA and FHA buyers, and it gives buyers strong leverage in negotiation. If it works but is older, you can often sell as-is with honest disclosure and, if needed, a modest credit or a home warranty. The right choice depends on the system's condition, age, and your timeline. For condo owners, check whether the system is in your unit or shared.

Why it matters in Arlington

VA and FHA appraisals require major systems to be functioning. A non-working furnace or air conditioner can lead the appraiser to require repair before closing. Because many Arlington buyers use these loans, you do not want a financing condition to catch you off guard. Also, with buyers holding more choices than in recent years, particularly in condos, a home with a major system problem is easy to pass over.

Repair versus replace

  • Repair. If the unit is relatively young and the issue is minor, such as a capacitor or thermostat, repair is cost-effective.
  • Replace. If the unit is old, uses obsolete refrigerant, or has major component failures, replacement may be wiser.
  • Partial approach. You can replace the failing component, such as an outdoor condenser, while leaving the rest.

Costs and returns

Replacement costs vary with size, efficiency, and ductwork condition, and can run from several thousand to well over ten thousand dollars. Sellers often do not recoup the full cost in price, but a working system can prevent a much larger concession. Buyers tend to discount for a failing system more than the cost of replacing it because of uncertainty. Get quotes from licensed contractors and ask about any manufacturer or utility rebates.

Alternatives to replacement

  1. Provide a home warranty. A seller-paid warranty can reassure buyers about mid-life systems.
  2. Offer a credit. A closing credit lets the buyer choose their own contractor.
  3. Service the system. A tune-up with a documented report shows the system is maintained.
  4. Price accordingly. Adjust the price to reflect a known upcoming replacement.

Condo considerations

Many Arlington condos have individual heat pump or furnace systems that belong to the owner, but some buildings have central systems maintained by the association. Check your documents. If the system is yours, you are responsible for it. Also check for rules about contractor access, installation approvals, and equipment placement, which can affect timing and cost for replacement in a high-rise.

Questions buyers will ask

Expect buyers to ask how old the system is, when it was last serviced, whether it has had major repairs, and what it costs to run. Have a model and serial number ready to confirm age, and gather maintenance records and utility bills. If the system uses an older refrigerant, be prepared to discuss it, since repair costs can rise. Clear answers show that you maintain the home and reduce the chance that buyers will assume the worst. A service report from a licensed technician within the past few months is a simple and inexpensive way to build confidence.

An example

Imagine a 19-year-old system in an Arlington townhome that still works but is noisy. A buyer's inspector notes it is near the end of its expected life. The buyer asks for $9,000 toward replacement. You could replace it for $8,500, give a credit, or offer a home warranty. If the buyer is using a VA loan and the appraiser sees the system functioning, the sale can proceed. If the system fails the day before closing, you may face a scramble. Knowing the state of the system early gives you control.
