Home inspection HVAC calls: Book before the deadline
The call that arrives with a closing date
Some HVAC calls come with a deadline the homeowner did not set. "The inspector flagged the furnace, and we close in nine days." The caller may not own the house yet. They may not be the one paying. What they need is usually not a repair. They need a dated visit and a written answer they can hand to someone else.
These calls are steady, not seasonal. NAR reported 4.06 million existing-home sales in 2025, according to PBS NewsHour, and NAR's December 2025 REALTORS Confidence Index found only 18% of buyers waived the inspection contingency. Most sales still run through an inspection, and every flagged system turns into a phone call to someone. The same NAR survey found contracts typically closed in 30 days, which is the whole window for the evaluation, the negotiation, and any work.
Who is on the line, and who pays
Three different people make this call, and each needs something different.
The buyer wants to know what the system will cost them, in writing, before the contingency expires. The seller wants to know the cheapest honest way to satisfy the buyer, which might be a repair, a replacement, or a credit. The agent is coordinating access and wants the report sent to the right person on time.
A desk that books every one of these as a standard service call misses the point. The buyer's agent cannot negotiate with "tech came out, system runs." The seller does not want a replacement quote emailed to the buyer without their say. Ask who is calling and who is paying before you ask anything about the furnace.
Five fields to capture before booking
The closing date and the inspection contingency deadline, if the caller knows it.
The caller's role (buyer, seller, or agent) and who pays for the visit.
The inspector's note, word for word. "Possible cracked heat exchanger" and "unit near end of expected life" are different visits.
Access: Occupied by the seller, vacant with a lockbox, or showing-only hours.
Who receives the written findings, and whether the other side may see them.
The inspector's wording matters most. A general inspection is visual, so many reports simply say "evaluate by a licensed HVAC contractor." A note that the air conditioning was not tested because it was too cold outside is a different job from a carbon monoxide concern.
Match the visit to what the caller needs
Caller and situation | Visit to book | What they leave with |
|---|---|---|
Buyer inside the contingency | Evaluation, dated well before the deadline | Written findings with repair or replacement estimate |
Seller asked to fix an item | Repair visit or evaluation first | Invoice and documentation the buyer can accept |
Agent coordinating access | Evaluation, report sent to the named party | Report to whoever the paying client chooses |
Any caller, safety concern noted | Same-day or next-day priority visit | Clear answer on whether the system is safe to run |
Buyer after closing, system down | Standard service call | Repair, and a new customer record |
What a slow answer costs
Run the math on your own market. Count last year's calls that mentioned an inspection. If it was 150, that is roughly three a week, and the real number is in your call log. Each one carries a possible replacement, and each one is time-boxed. A caller with nine days to closing will book whoever answers first and offers a date. Voicemail or "we will call you back with availability" usually means they called the next company before you returned the call.
The NAR survey also found 14% of contracts had delayed settlements and 5% were terminated in the prior three months. The HVAC evaluation is rarely the only cause, but nobody wants their report to be the reason a closing slips.
The second sale happens after closing
If the buyer goes through with the purchase, your caller is about to be a new homeowner with no HVAC company. You already have the equipment age, the model, and the history. That is the moment to offer a maintenance membership, which our post on membership capture covers in detail.
Revin's voice agent answers every call at once, around the clock, so the Saturday call from a buyer's agent is answered the same as the Tuesday one. It is trained on your own recordings and scheduling rules, asks the five questions, books the dated evaluation into ServiceTitan during the call, and transfers seller negotiations or anything unusual to your team with the details captured. Your CSRs keep the conversations that need a person.
What happens if the furnace fails a home inspection?
A flagged furnace does not stop a sale by itself. The buyer usually orders an HVAC evaluation inside the inspection contingency period, then uses the written findings to ask the seller for a repair, a replacement, a price reduction, or a credit at closing. If the parties cannot agree, the buyer may be able to walk away under the contingency, depending on the contract terms.
Who pays for HVAC repairs after a home inspection?
It depends on what the buyer and seller negotiate. The seller may agree to repair or replace the system before closing, give the buyer a credit, or lower the price. Sometimes the buyer accepts the house as is. The evaluation visit itself is usually paid by whoever orders it, so the HVAC company should confirm who is paying when the visit is booked.
Should I get an HVAC inspection before buying a house?
If the general inspector raises any concern about the heating or cooling system, yes. A home inspector looks at the system broadly, while an HVAC technician can test it, judge its condition, and estimate repair or replacement. Book the evaluation early in the contingency window so the written findings arrive in time to use in the negotiation with the seller.
Can a home inspector tell if a furnace is cracked?
Not reliably. A general home inspection is visual and limited, so an inspector may note signs that suggest a cracked heat exchanger and recommend further evaluation. Confirming it takes an HVAC technician with the right tools and access to the equipment. That is why many inspection reports say evaluate by a licensed HVAC contractor rather than giving a final answer.
Should the seller replace the furnace before closing?
Sometimes, but not always. Replacing it before closing lets the seller control the cost and choose the equipment, but it needs time the schedule may not allow. A credit at closing is faster and lets the buyer choose their own contractor. Sellers often ask for a written evaluation and a replacement estimate first, so they can compare repair, credit, and replacement on real numbers.
