What Should an HVAC Website Include? What 29 Chicagoland Sites Got Wrong

HVAC companies had the fastest websites of any trade when I tested 103 Chicagoland contractor sites this summer. Median server response of 0.42 seconds, more than three times quicker than the plumbers. Then I checked whether a homeowner on a phone could reach them, and 31% of the HVAC sites gave that person nothing to tap.

Fast, and still losing the call.

So what should an HVAC website include? More than speed, and less than most agencies will try to sell you. An HVAC company has three different visitors, and they want different things from the same site. The furnace-is-dead caller in January. Next, a homeowner pricing a full replacement who reads every page twice. Then there’s the one you already served, who should be on a maintenance plan and probably isn’t. Here’s what each of them needs, built from what the 29 HVAC sites in my contractor website statistics test got right and wrong.

HVAC Sites Were the Fastest in My Test and Still Lost the Call

This is how the HVAC group compared with the other trades that had enough sites to measure.

The speed number is genuinely good. Most of the HVAC sites I tested run on hosting that answers quickly, which puts them ahead of Google’s 0.8 second threshold and well ahead of the plumbing sites I tested.

But look at the phone column. Roughly nine of the 29 HVAC homepages had no tel: link. The number was usually right there in the header, as plain text. On a laptop it looks finished. Tapping it on a phone does nothing, and the homeowner has to memorize ten digits, back out of the site, and dial by hand. With the house at 54 degrees, a lot of them won’t bother. They’ll tap the next listing instead.

The single heaviest homepage in the entire study was an HVAC company too. 13.4 MB, with 52 separate images. The server responded fast. Its page would take ages to finish on a phone with weak signal in a basement mechanical room, which is exactly where someone standing next to a dead furnace is holding it.

That’s the lesson I’d take from the HVAC numbers, and it’s the first thing to fix before you worry about anything else an HVAC website should include. Somebody paid attention to hosting and then nobody tested the site the way a customer uses it. If you haven’t done that in a while, how fast your website should load walks through the ten-minute check.

What Should an HVAC Website Include Above the Fold?

Start with the emergency caller, because that visitor decides fast and pays well.

When a furnace quits in a Chicagoland January, nobody collects three quotes. They search and call the first company that looks real and local. Your homepage has maybe five seconds to prove you’re both. On a phone, before anyone scrolls, they should see:

• A phone number that dials when tapped. Big, at the top, and repeated in a sticky bar on mobile if your site supports one.
• Whether a person answers after hours. “24/7 no-heat service” if you do it, your real hours if you don’t. Hiding this makes people assume the worst.
• The towns you cover, by name. “Serving Naperville, Aurora, Wheaton and Downers Grove” beats “Serving Chicagoland” every time, since nobody calls until they know you’ll come.
• One line about what you fix. Furnaces, boilers, AC, heat pumps. If you don’t touch boilers, say so here and save both of you the call.

That’s the whole list for the top of the page. Everything else, the company history and the wall of brand logos, can live further down or on another page.

I’d add one HVAC-specific thing. Split the call to action by season. In October through March, lead with no-heat service. From May through August, lead with AC. A contractor whose homepage still says “Beat the Heat!” in January looks like nobody’s minding the shop, and homeowners notice more than you’d think.

The Replacement Buyer Reads Every Page

The second visitor is the opposite of the first. Their system is fifteen or twenty years old, a tech just told them the heat exchanger is cracked or the compressor is going, and they have a replacement quote in hand that runs into thousands of dollars. They’re not in a hurry. Getting ripped off is what scares them.

This person will read your site end to end, then read your competitors’ sites, then come back. Heating and cooling is a big enough slice of their household bills to justify the effort. The U.S. Energy Information Administration puts it at 52% of a household’s annual energy use between space heating and air conditioning. A homeowner who’s just learned that is going to ask hard questions about efficiency ratings.

Plenty of HVAC sites give this visitor almost nothing. A services page with one paragraph per service and a “Request a Quote” button. That’s a page for someone who already trusts you, and the replacement buyer doesn’t yet.

What they want to find:

• A replacement page for each system type you install. Furnace, central AC, heat pump, boiler if you do them. Explain the difference between single-stage and variable-speed in plain words, and when each one is worth the money.
• How you size a system. If you do a real load calculation instead of matching whatever tonnage came out of the basement, say it. Most homeowners have never heard of one, and hearing it separates you from the guy who quoted over the phone.
• Financing, stated clearly. If you offer it, put the terms on a page. A buyer staring at a large number wants to know about monthly payments before they call, not after.
• What install day looks like. How many hours, whether the heat will be off overnight, who hauls the old unit away, what the permit covers. Small details, and they’re the ones that make a stranger comfortable letting your crew into the house.
• Photos of your own installs. Real basements, real crews. A clean install with labeled lines and a new pad sells better than any manufacturer’s glossy render.

I’d also publish a price range. I know most HVAC owners hate this idea, because every house is different. The buyer is going to find a range somewhere, and it may as well be yours, with your explanation of what moves the number up or down. Any company willing to say “most furnace replacements we do land between X and Y, and here’s why yours might not” earn trust the rest of the market is leaving on the table.

Take Down the Tax Credit Banner

This one’s specific to right now, and it matters for anyone who built their site in the last few years.

The federal Energy Efficient Home Improvement Credit, the one that paid homeowners up to $2,000 a year toward a qualifying heat pump, covers improvements made through December 31, 2025, per the IRS. A heat pump installed this year doesn’t qualify. If your site still has a banner promising a $2,000 tax credit, a homeowner who books on that promise is going to feel lied to when their accountant tells them otherwise, and that’s a review you’ll wear for years.

Check every page for it. Homepage banner, heat pump page, the blog post somebody wrote in 2023, the footer. Replace it with whatever’s current, which in northern Illinois is mostly utility rebates from ComEd and the gas companies. Those programs change amounts and eligibility rules often enough that I’d link to the utility’s own page instead of quoting a dollar figure you’ll forget to update.

Refrigerant belongs on this list too. New residential air conditioners and heat pumps made since January 1, 2025 have to use a refrigerant with a global warming potential under 700 under the EPA’s rules, which is why R-410A is on its way out and quotes now mention R-454B or R-32. Homeowners see those codes on a proposal and start searching. A short page answering “does my old R-410A system still work and can it be repaired?” in your own words catches that search and makes you look like the company that knows what’s changing.

Stale information costs more on an HVAC website than on most. Your customer is spending real money on equipment they don’t understand, and one outdated claim makes them doubt everything else you wrote.

Maintenance Plans Deserve Their Own Page

The third visitor is already your customer. You fixed their furnace last winter. On a lot of HVAC sites, the only way they’d find out about a maintenance plan is if a tech mentioned it on the way out the door.

That’s backwards. A maintenance agreement is the steadiest revenue in the business, and it keeps your crew booked in the shoulder months when the phone goes quiet. ENERGY STAR recommends checking the cooling system in spring and the heating system in fall, since contractors get busy once the weather turns. That’s two visits a year. It’s also a sales pitch the federal government already wrote for you.

A good maintenance plan page has four things on it. What each visit includes, in a list someone can read in thirty seconds. The price, per year or per month. What members get that non-members don’t (priority scheduling during a cold snap is the one that sells). Last, a way to sign up without calling, because the person reading this page is calm and would rather fill out a form than wait on hold.

Of the 29 HVAC sites in my test, 31% had no contact form at all. For an emergency, that’s survivable. People call. For a maintenance plan, it’s a dead end, since the person ready to sign up on a Tuesday evening has nowhere to do it.

Service Area Pages for the Towns You Actually Drive To

Every HVAC company wants to rank for its trade plus every suburb in range. Most try to do it with a footer listing forty town names, which does very little.

What works better is a real page for each town you get a lot of work in. Not a copy of the homepage with the town name swapped in, since Google’s gotten good at ignoring those. A page that talks about the houses you work on there, whether that’s older ranches still on original ductwork or newer builds going to heat pumps, plus jobs you’ve done in that town and reviews from customers who live there. Five honest town pages beat forty thin ones.

Those pages feed the regular search results. The map pack, the box of three businesses at the top, runs mostly on your Google Business Profile and your reviews. You need both, and the website pages are what make the Business Profile look credible once someone clicks through. For an HVAC company, the map pack also competes with Local Services Ads for the same eyeballs. I worked through that math for HVAC and the other trades in whether Google Local Services Ads are worth it.

Build It Before the First Cold Snap

Here’s the timing problem with HVAC websites. The searches that matter most, no heat and furnace replacement, pick up in the fall and spike when the first real cold hits. A page you publish in December is a page Google hasn’t finished crawling and ranking until the season’s half over.

So the right time to fix your site is before the weather turns. Put a tappable phone number on every page and check it on your own phone. Update the heat pump page and pull anything about the expired tax credit. Write the maintenance plan page. Add a form. None of that is a redesign. Most of it is an afternoon, and for a company with a fast server already, it’s the difference between a site that looks ready and one that answers the phone.

If you’d rather hand the whole thing off, HVAC websites is what we build for Chicagoland companies, on flat monthly plans that include the updates. We’re easy to reach.
