On this page
An HVAC FAQ page works when each answer is written in your own words from your own service calls, gives the direct answer first, and says what you will confirm at the house. Cover no heat or no cooling, how fast you can arrive, what a visit costs, repair or replace, sizing, maintenance, financing and warranty. Do not promise arrival times, savings or repair outcomes.
Key takeaways
- Write each answer from your real calls, with the direct answer first and the exceptions after it.
- Leave gas smell, carbon monoxide and electrical safety wording to your gas utility, your fire department and your lead tech.
- Never promise an arrival time, a repair result, a utility savings figure or financing approval.
- State your licensing, insurance and warranty terms exactly as they are, and only if they are true.
- Google stopped showing FAQ rich results on May 7, 2026, so write the page for customers, not for markup.
An HVAC customer reads an FAQ page in one of two moods. Either the house is too hot or too cold and they want a human on the way, or they have two quotes in hand and want to know which company sounds like it knows the work. A good page serves both, and it takes pressure off your phones because your dispatcher stops answering the same eight questions all day. Each idea below is a question customers really ask in this trade, what your answer must cover, and what to avoid promising. We do not state technical, safety or legal answers here as fact, because they depend on the equipment, the house, your state and your city. Confirm each one with your lead technician and write it in your own voice. For the larger plan around your site, see our HVAC industry page and HVAC SEO guide.
1. My furnace stopped working. What should I check before I call?
Cover: the two or three checks your dispatcher already walks people through on the phone, such as the thermostat mode and batteries, the breaker and the furnace switch, and the air filter. Add what information helps you: the brand on the label, any blinking light code, and when it stopped. Avoid: instructions that have a homeowner open panels or touch gas or wiring. Confirm with your lead tech: which checks actually save you wasted trips, and which ones only delay a real repair.
2. My AC is running but the house will not cool. What is going on?
Cover: the causes your techs see most often in your area, written as possibilities, and the simple homeowner checks that fit (filter, thermostat setting, vents blocked by furniture). Say when to turn the system off and call. Avoid: naming one cause as if it were certain, and any advice about refrigerant, which is work for a qualified person. Confirm: what your company asks a caller to do before booking, so the page and the phone script say the same thing.
3. How soon can you get here?
Cover: your hours, whether you take same-day and after-hours calls, how a customer gets a window, and how you tell them when a tech is on the way. Say what counts as an emergency visit in your company and what happens to everything else. Avoid: promising "within the hour" or a guaranteed time. A cold snap or a heat wave fills every schedule at once, and a promise you miss costs more than a wider window honestly stated. A phone line that books into real open slots keeps the answer true overnight.
4. Do you charge for a diagnostic visit, and what does it include?
Cover: what the visit fee pays for, whether it is credited when the customer approves the repair, whether after-hours or weekend visits cost more, and that a written quote comes before any work. Avoid: dollar amounts you will not honor on every call. If you publish a number, date it and keep it in one place so a price change means one edit. Our guide to pricing HVAC service jobs covers the math behind your fee so the page matches your books.
5. How much does a new furnace or AC system cost?
Cover: the things that move the total in your market: system type, equipment tier, the size of the house, ductwork condition, the electrical or venting changes the install needs, and permit handling. Explain that you give a written, itemized quote after a visit. Avoid: a single "starting at" figure that few customers will actually pay, and any promise about monthly savings. Offer a good, better, best structure on the page in words, so a reader understands what the options buy before anyone visits.
6. Should I repair my system or replace it?
Cover: the questions you ask yourself on the job: the age, the repair history, the cost of this fix against a new system, whether parts are still available, and what the customer plans for the house. Avoid: any fixed rule that decides for the customer, and any sign that you steer toward replacement to raise the ticket. Say you will explain both options in writing. A sentence like "we will tell you when a repair is the better buy" is only worth printing if your techs live by it.
7. How do you decide what size system my home needs?
Cover: how your company actually sizes equipment, in plain words, and what you look at in the house. Confirm with your lead tech or comfort advisor: whether you run a load calculation, which method you use, and what you measure on site. Describe your real process, not an ideal one. Avoid: rules of thumb you do not follow, and claims that a bigger unit is always better or worse. A customer who has read this answer will compare it against the other quote, so it has to be accurate.
8. How often should my system be serviced, and what happens during a tune-up?
Cover: the schedule you recommend for heating and cooling equipment, a checklist of what a tech actually does on a visit, and what you do when you find a problem (a written note first, then a quote, never a surprise add-on). Avoid: blanket claims that service prevents breakdowns or extends life. Say what you inspect and what you report. If you sell a maintenance plan, list what it includes and how it renews.
9. How often should I change my air filter, and which one do I buy?
Cover: where the filter lives in the systems you service, how a customer reads the size off the old one, and why you ask them to check it more often during heavy-use months. Confirm: the replacement interval you give customers and any filter types your equipment does not tolerate, using the manufacturer's manual as your source. Avoid: one interval for every house. Pets, dust and construction change it, and a customer who follows your page to the letter should not get a bad result.
10. Do you work on heat pumps, mini splits, boilers and older equipment?
Cover: a plain list of equipment you install, equipment you only repair, and equipment you refer out. Name brands you service only if your techs are trained and stock parts for them. Avoid: saying "we fix everything." A customer with a boiler who reads that and gets turned away at the door will not come back. Naming what you do not handle sends the right calls to your phones and builds trust with the rest.
11. Are there rebates or tax credits on a new system?
Cover: that programs exist, that they change, and where the customer finds the current rules: the program's own site and their utility. Avoid: quoting amounts or eligibility. Those depend on the equipment model, the year of purchase, the customer's tax situation and the utility, and a wrong number on your page becomes a promise you did not mean to make. Link to the program page itself, and say who on your team can tell a customer which models are listed. Tell readers to talk to a tax professional about credits.
12. Do you offer financing?
Cover: only what is true: whether you work with a lender, who the lender is, how a customer applies, and that approval and terms come from the lender. Avoid: "easy approval," "no credit check," or any promise of a rate. Do not publish payment examples unless the lender's compliance contact has approved the wording, because lending ads carry their own disclosure rules. If you do not offer financing, say how customers usually pay and which cards and methods you take.
13. Are you licensed and insured?
Cover: what your state and city require for heating and cooling work, the license or registration you actually hold, how a customer can verify it on the issuing agency's site, and the insurance you carry. Avoid: any word about licensing or insurance that is not literally true for your company, and any claim about another company's status. Rules differ by state and sometimes by city, so look up your own requirements and copy the wording from your licensing agency. Our guide to becoming an HVAC technician shows how the pathway works.
14. What does the warranty cover?
Cover: the difference between the manufacturer's warranty on equipment and your own labor warranty, what registration the manufacturer requires, how long your labor coverage runs, and what voids either one. Confirm: every term against the paperwork you hand customers. Avoid: a vague "full warranty" line, and any promise that a part will never fail. Tell the reader whom to call when something goes wrong, and how quickly you respond to a warranty call.
15. How long does an installation take, and do I need a permit?
Cover: a range from your own recent installs by job type, what the crew does on day one, and what can stretch the job (ductwork changes, electrical work, a late part). Say who pulls permits and schedules inspections. Avoid: stating what local codes require. Permit and inspection rules differ by town, so name your office as the contact and say you handle it, if you do. Confirm: the typical timeline with whoever schedules installs, and update the answer each season.
16. What should I do if I smell gas or my carbon monoxide alarm goes off?
Cover: a short, plain pointer to the right authorities, in words your gas utility and local fire department already publish. Link to their pages. Avoid: inventing your own safety instructions, offering diagnosis over the phone, or turning a safety page into a sales pitch. This page is the one place where speed matters most and cleverness has no value. Ask your gas utility for approved wording, put a call-to-action for your service only below the safety message, and have your phone staff trained to say the same thing.
A note on FAQ markup
Google's search update log says the FAQ rich result stopped appearing in Google Search on May 7, 2026, and that the documentation for it was removed in June 2026. Google's documentation had said since September 2023 that the feature was limited to well-known, authoritative government and health sites. Structured data is no longer a reason to build this page. If your website builder already adds FAQPage markup, it has to match the questions and answers shown on the page, so remove it if it does not. The page still answers real calls, and visible answers can be read by assistants and search summaries. See Google Search Central's update log for the dates.
Where to start
Write these three first, because they match the calls your office takes on the worst days of the year:
- Question 1 or 2, whichever season you are in. No heat in winter, no cooling in summer.
- Question 3, how soon you can arrive. Make it match what your schedule really does.
- Question 4, the diagnostic visit. It is the first money question every caller asks.
Then add the rest one a week, using real questions from your call notes. If you want a website built so each answer sits on a page that loads fast on a phone, that is part of what we build, and our HVAC marketing ideas list shows where else the answers can be reused.
Frequently asked questions
How long should each FAQ answer be?
Two to five sentences. Lead with the direct answer, add the one exception that matters, and say what you will confirm at the house. Longer topics deserve their own page with a link.
Should I put prices on an HVAC FAQ page?
Only prices you will honor on every call, dated and kept in one place. If prices vary by house, explain what moves them and how a written quote works instead.
Where do I find the real questions to answer?
Your call notes, texts, website form entries and what technicians hear in driveways. A list of the ten questions your office repeats most is a better source than any keyword tool.
Do I need schema markup on the FAQ page?
No. Google no longer shows FAQ rich results. If your site already has FAQPage markup, it must match the visible text on the page.
