Our build for Easy CleanoutsTrusted by 200+ businesses across 9 industries
HVAC website design should sell the maintenance plan as hard as the repair. We build sites for heating and cooling companies that want steady work all year, with plans and pre-season tune-ups front and center. Every repair page offers the plan too. Most HVAC sites launch in six to eight weeks.
Next, a few quick questions about your project. If it is a fit, you pick a time for a free 15-minute call.

We treat an HVAC site as a sales tool for plans. That changes what we build first.
Your phone rings hardest in the first hot week and the first cold snap. Those calls pay well, but they come in bursts. Many of those customers forget your name once the system runs again.
The work that evens out the year is maintenance. ENERGY STAR tells homeowners to have the cooling checked in spring and the heating checked in fall, before contractors get busy. Yet most HVAC sites mention a plan once, in a list of services. We give the plan its own page with prices, visit details and a sign-up form. Then we offer it on every repair page.
Then there is the big decision. When a system gets old, the owner wants to know whether to fix it or replace it. A page that answers honestly, even when the answer is repair, earns the replacement quote later.
We design the plan page before the homepage. When the site sells plans, the busy season pays and the slow months get easier.
Guard Dog Security saw a 95% higher conversion rate within 4 weeks of launching a lead page we built. Your tune-up offer page gets the same focus: one offer, one form.
Our replacement pages tell owners when a repair still makes sense. People remember the company that told them to wait.
We test every page on phones over slow connections, so a homeowner with a dead AC in July can still book.
Homeowners read this guidance before they hire. Your site should line up with it.
ENERGY STAR advises a pre-season check-up every year: the cooling system in spring and the heating system in fall. Its reason is that contractors get busy once summer and winter come.
What it means for your siteOpen tune-up booking before each season and show the plan to every visitor. ENERGY STAR is already telling them to call someone.

ENERGY STAR says it may be time to consider replacing a heat pump or air conditioner that is more than 10 years old. For a furnace or boiler, the age is more than 15 years.
What it means for your siteAsk for the system age in your repair form, and build a repair or replace page around those numbers. You will see which calls may turn into replacement quotes.

EPA rules under Section 608 of the Clean Air Act cover technicians who maintain, service, repair or dispose of certain equipment. If that equipment could release ozone depleting refrigerants, the technician needs EPA certification.
What it means for your siteList each tech with their certifications on the site. It tells a homeowner who is coming to the house and shows that you follow the rules.

Most of this list sells plans and fills the slow months. The rest helps you win replacements.
Plan tiers, what each visit covers, the price and a sign-up form, written to sell the plan rather than list it.
A cooling tune-up page for spring and a heating one for fall, each with online booking.
A short box beside the repair form that shows member perks, like priority visits or repair discounts, if you offer them.
Pages on system age, repeat repairs and sizing, so a homeowner can judge an old unit before you visit.
Short bios with photos and certifications, including EPA Section 608, so people know who is coming.
If you offer financing or know of utility rebates, a clear note near the replacement quote form.

Six steps. We plan the launch around your seasons, so tune-up pages can go live before the rush when the calendar allows.
Want to plan ahead? Give your site a yearly tune-up
We learn what your maintenance plan includes, what it costs and when your slow months hit. No plan yet? We draft a simple page and you set the terms.
We map the plan page, the tune-up pages, repair pages and replacement guides, and how each one leads to the next.
Our writers draft every page. You check plan details, prices and any technical claim.
We design the plan page and one repair page first, since those do the most selling. The rest follows.
We build on WordPress, connect sign-up and booking forms to your inbox or software, and test each one on phones.
The site goes live. We send a test plan sign-up and a test tune-up booking, then cover fixes for the next 30 days.
Run through these before spring and fall. Each gap is a spot where a plan sale or a tune-up booking slips away.
All three plans are one-time prices with copywriting and a WordPress build included. A plan page, two tune-up pages and the core service pages usually take an HVAC company past six pages. That makes the $2,800 plan for bigger sites the common fit. A small shop can start on the $1,400 plan and add pages later.

Give the plan its own page with the price, the number of visits, what each visit covers and the perks. Then offer it on every repair page and after each online booking. A customer who just paid for a repair has a fresh reason to want a plan.
We think so. A plan is a small, repeat purchase, and asking people to call for the price adds a step many will skip. If the price depends on how many systems a home has, show the starting price and what changes it.
What the visit includes, how long it takes and what it costs, with the booking calendar right below. Add a line on why spring and fall matter, since ENERGY STAR gives homeowners the same advice.
Yes. We can connect a payment tool such as Stripe, so customers pay for a plan once or every month. A full member account area is a bigger custom project.
Build a page on the signs ENERGY STAR lists: age, frequent repairs, rising bills, rooms that stay too hot or cold, and humidity problems. Tell the homeowner when a repair still makes sense. That honesty earns the replacement job later.
Yes. If you install heat pumps, ductless systems or high-efficiency furnaces, each gets its own page. It covers how the system works, who it suits and what affects the price.
Explain how you size a system. ENERGY STAR tells buyers that bigger is not always better. It says the system should fit the size of the home, its insulation and its windows. Show that you work that way, then share a sample itemized bid.
Yes. A name, a photo and the certifications each tech holds, such as EPA Section 608, tell the homeowner who to expect at the door.
For a small shop, yes. Home, repair, replacement, the plan page, about and contact fit in six pages. Add tune-up pages and separate heating and cooling pages, and you will want the $2,800 plan for bigger sites. Sites with 30 or more pages cost $5,600, and you pay each price once.
About two months. Most HVAC sites take six to eight weeks, so starting then gives the tune-up pages time to go live before the rush.
Yes. The site runs on WordPress, and we train whoever runs your office. Plan prices, seasonal offers and tech bios are simple edits.
