HVAC second opinion calls: How to book the replacement
"Another company said I need a new furnace"
The first cold week of October brings a call your desk has heard before. The heat came on, something failed, a technician from another company came out, and now the homeowner holds a replacement quote. They are calling you to find out whether it is true.
That caller is not a cold lead. They have a diagnosed problem, a budget conversation already started, and a competitor's number on the kitchen table. A second-opinion call is the warmest replacement lead your desk will take all week. Most desks treat it like any other no-heat call and lose it.
How the desk usually loses it
There are three common ways. The first is booking it as a standard diagnostic. The technician arrives in repair mode, does not know there is a competing quote, and either fixes a part or leaves without a replacement conversation. The second is price matching on the phone. A CSR who says we can probably beat that has entered an auction it cannot see. The third is the opposite mistake: A same-day replacement pitch from a comfort advisor who arrives with brochures and makes your company look exactly like the one the homeowner is doubting.
Search for an HVAC second opinion and the results are contractor pages offering a free second opinion and listing red flags, such as a quote given by phone or no load calculation. Your caller has probably read one. They are testing whether you are different.
The four facts to capture
The call needs four facts before anyone decides what kind of visit to book.
Fact | How to ask it | Why it matters |
|---|---|---|
The competing recommendation | What did they recommend, and do you have the written quote? | Equipment, scope, and price frame the visit |
The failed part or diagnosis | What did the technician say was wrong? | A cracked heat exchanger and a failed igniter are different calls |
System age | About how old is the system, or when was it installed? | Age is the strongest repair-or-replace signal |
Running status | Is the heat working right now? | Decides how fast the visit has to happen |
Ask the homeowner to text or email a photo of the written quote. It saves the technician 15 minutes and tells you whether a load calculation was done.
Route by the state of the system
The four facts sort the call into three paths. If the heat is out, it is a no-heat call first; the dispositions in our after-hours no-heat guide apply, and the technician goes today knowing a replacement quote exists. If the other company red-tagged the system for a safety issue, the desk tells the caller to keep it off and makes sure a carbon monoxide alarm is working, then books the earliest visit. If the system is running and the caller holds a replacement quote, book a comfort advisor visit with a load calculation, and tell the caller that is what will happen.
How to route a caller to a comfort advisor instead of a callback pile is covered in our heat pump rebate post. The difference here is the brief: The advisor should arrive with the competing quote in hand.
Sell measurement, not price
The honest pitch for a second opinion is that you will measure before you recommend. It is also the right one. ENERGY STAR notes that improper installation can reduce system efficiency by up to 30 percent. A 2014 NIST study found that installation faults, led by leaky ducts, refrigerant undercharge, and wrong indoor airflow, could raise heating and cooling energy use on the order of 30 percent. A replacement sized by matching the old nameplate repeats whatever went wrong last time.
The script never criticizes the other company. It says we will look at the same system, measure the house, and tell you in writing whether we agree. Sometimes you will agree, and you win the job on trust. Sometimes the part really can be repaired, and you win a customer who will call you for the next replacement.
The math on a second-opinion lead
Run it on your own numbers. As one illustration, a shop that takes 40 second-opinion calls in a heating season and books them as plain diagnostics might close a handful as replacements. Routing the running systems to a prepared advisor visit only has to win a few more to matter, because each one is a full system at your average replacement ticket. Track second-opinion calls as their own disposition so you can see the close rate.
The bottleneck is recognition. A CSR covering a full queue in the first cold week will not always catch the phrase another company told me. An AI agent such as Revin answers every call at once, recognizes second-opinion language, asks the four questions, requests the quote photo by text, books the right visit type into ServiceTitan, and transfers the caller to your team with the details attached when they want a person. Your best replacement leads are already calling you. Make sure the desk knows which ones they are.
Should I get a second opinion on HVAC replacement?
Yes, when the recommendation is a full replacement and the system is still running or the failed part could be repaired. A replacement is one of the largest purchases a homeowner makes, and a second visit costs little time. A good second opinion checks the failed component, the age and condition of the system, and the size of the home before agreeing or disagreeing. If the first company red-tagged the system for safety, keep it off until the second visit.
How do I know if my furnace really needs replacing?
Look at the age of the system, the cost and frequency of recent repairs, whether a major component such as the heat exchanger has failed, and whether the home is comfortable. A furnace with a cracked heat exchanger is a safety issue and usually a replacement. A failed igniter, inducer motor, or control board on a younger system is often a repair. A technician who explains the specific failure, in writing, gives you something you can compare.
Is a free HVAC second opinion really free?
It depends on the company. Some contractors waive the visit fee for second opinions on replacement quotes because the visit is a sales call. Others charge their normal diagnostic fee and credit it toward the repair or the new system. Ask on the phone what the visit costs, what it includes, and whether the technician will put the findings in writing. A clear answer to those three questions is a good sign about the company.
Can a contractor size a system without a load calculation?
They can, but it is a warning sign. Sizing a new system by matching the old unit or by square footage alone repeats any mistake made at the original install. A load calculation measures the home's actual heating and cooling needs, including insulation, windows, and ductwork. ENERGY STAR notes that improper installation can reduce system efficiency by up to 30 percent, so sizing and installation quality matter as much as the equipment brand.
Is it rude to get a second HVAC quote?
No. Comparing quotes on a major purchase is normal, and reputable contractors expect it. You do not need to tell the first company, and you do not need to share their price unless you want to. Sharing the written quote can help the second company compare the same equipment and scope. A contractor who pressures you to sign the same day, or criticizes you for asking, has given you useful information about how they work.
