HVAC Website Design (2021 Update)

The foundation of an HVAC company’s online presence is website design. A healthy website facilitates search engine optimization, brings legitimacy to your brand, and helps convert traffic into leads. Digital marketing concepts like SEO, PPC, and content marketing increase online visibility, but the website’s quality converts that exposure into sales. Many factors dictate a website’s design quality. Still, as a heating & cooling contractor, the ultimate goal is to grow your business online and capture leads and sales within your local service area.

In 2021, anybody can build a website. With DIY website builders like WixWeebly, & Squarespace, along with an abundance of templates for content management systems like WordPress, it’s never been easier to get a functional webpage published. But design is not always about the front-end visual display of a website. The codebase is a significant consideration in website design, especially as it pertains to SEO and marketing. The back-end of a website requires creation as well, and it is as important, if not more so than the visual presentation.

What is HVAC Website Design?

Website design is constructing websites with layouts, user interfaces, and other aesthetic imagery, including graphics. Without a functional website, it’s challenging for HVAC companies to convert leads. Even if you pay for PPC ads on Google, Facebook, or other platforms, the absence of a converting landing page will nullify the majority of clicks. Even SEO, which is an organic methodology, is heavily reliant on the quality of the website. While there are more platforms on which to promote a brand than a decade ago (Social Media, Google My Business, Etc.), you can’t maximize any of them without a related website. Since contractors’ goal is to increase sales, the direct correlation between web design and sales conversions should be enough to garner focus.

In our search engine optimization guide, we demonstrate the importance of generating traffic to your website. But the harsh reality of any internet marketing method is that it is only as valuable as its final result. In many ways, website design is a part of search engine optimization. Attempting to implement one without the other is a waste of marketing resources. By keeping your focus on the ultimate goal (sales), you can take actions that align with this underlying motivation and stay the course to reach your desired destination.

When HVAC workers talk about their brand, they mean their trust level within their community. A functional and appealing website does wonders to strengthen a brand. Consumers invest trust in companies that showcase their professionalism with a website, but search engines like Google reward them as well. Aside from converting traffic that reaches your domain, robust web design can also influence said traffic and serve as a central hub for inbound links from all of your secondary media platforms like Facebook, Google My Business, and even Yelp. Digital footprints leading back to a primary domain increase its authority as well as the legitimacy of your brand online.

Website Presentation

The front-end of a website is what most consumers take notice of immediately. It is the only thing users consider when judging your site, especially those without the knowledge of HTML, CSS, or any other coding language. So what do viewers prefer? Factors like colors, white space, aesthetics, and overall user experience top the list. Many of these work on a subconscious level, and the user may not express why they like the looks of a website, only that they do.

In 2021, presentation is more dynamic than ever before. Consumers visit websites on various devices, including mobile, tablet, and desktop, and thousands of iterations of each. A website should appear optimally on each machine, which is attainable through responsive design principles. When a website is responsive, it adapts to the user’s device without having to create an entirely new website for each one. Google has gone as far as to recommend responsive design principles to professional web designers.


Palettes are critical in modern design. They inform the experience of the visitor, but they create cohesion between brand and platform. The diversity of a palette stems mainly from an HVAC company’s logo. Creating or updating your company logo is of great importance. A logo with lots of colors will distract the average user, but a logo with only one color will bore them. Having 2 or 3 colors, a primary and 1 or 2 secondaries, is ideal in modern website design.

White Space

A funny anecdote about white space is that it is not always white. The phrase refers to empty spaces between images, text, and blocks of content. The modern consumer prefers information that is digestible since they can become overwhelmed by excess. The function of white space is to foster a feeling of organization and conciseness. Both can improve the visitor’s experience, and both can influence behavior metrics like bounce rate, pages per site, duration on site, etc.


If you’ve ever heard a visitor discuss the “feel” of a website, aesthetics are at play. Defined as the “appreciation of beauty,” aesthetics might not be something HVAC contractors think about for their business. But make no mistake, everyone considers aesthetics in website design. That includes your prospective customers who are reading about heating & cooling services. Don’t assume that the subject matter disqualifies any website from aesthetic appeal.

On Page Aesthetics Example

Website Functionality

A website’s look and feel have great appeal, but its functionality can make or break its effectiveness. Let’s say a user enters your HVAC website and likes what they see. Imagine now that as they are attempting to navigate to other sections of the site via a smartphone browser, that they can’t seem to scroll down or click the desired page links properly. Once something like this occurs, the visual appeal becomes mostly irrelevant. Users will leave a website for functional reasons instantly (literally) and never return, regardless of the site’s visual impression.

Navigation is one element of usability but is not the only one. Consider site speed (loading time), URL structure, menu links, and user interface as some of the other most prominent factors. Responsive design is equally essential since usability should translate to all kinds of devices, from mobile to desktop, to tablet, including the endless variations of each device category (iPhone, Android, MacBook Pro, HP, etc.). The user must be able to use your website at their convenience because they will move on to the next search result, which does it better.


Nine times out of 10, the most frustrating part of a poorly designed website is its navigation. If the user cannot scroll properly and get to other sections of the website with ease, they will become discouraged and exit the site. Mobile websites are typically the most complicated to navigate, which is why designers should pay extra close attention to mobile design. Since the screen is smaller than a tablet or desktop monitor, it should be incredibly convenient for the user to find their way around the site and all of its elements, scrolling primarily with their thumb and index finger.

Example of Scroll Bar Navigation

Site Speed

Over half of internet users will exit a website that does not load within 3 seconds. That puts HVAC websites on the clock immediately after a user clicks on their result. If we’re honest with ourselves, that 3-second number is likely to have lowered even more in recent months. In 2021, that number is more than likely closer to 1 second. The attention spans of users have shortened, and designers must take notice. You can check your existing website speed using Google PageSpeed Insights, giving suggestions for correcting errors.

URL Structure

A website URL hierarchy is an integral part of a site’s functionality for users. If you have pages for each service, the URLs should be both logical and hierarchical. Let’s say you provide both residential and commercial HVAC services. If so, a page for residential ac repair should be categorized as a child page underneath the parent page, residential HVAC services. A sound hierarchy closely relates to your HVAC SEO efforts and helps the user navigate your site.

Parent Child Page Structure Example

Menu Links

Useful HVAC websites link every critical page from the homepage menu. When converting traffic into customers, you want them to see all the services you offer and easily access the one that intrigues them. In alignment with URL structure, menu links should have main categories (parent pages) and subcategories (child pages). You should also have a Contact Us page and an About Us page to help connect with the visitors.

Menu Links Screenshot

User Interface (UI)

User interface, often shortened as UI, hones in on the user’s projected need from your website from a functionality standpoint. According to Usability.gov, UI combines interaction design, visual design, and information architecture. They break down UI elements into four sections: input controls, navigational components, informational components, and containers. They stress simplicity, consistency, and purpose as the driving principles of an effective user interface design.

Website Coding

Most visitors make a judgment about a website based on its front-end presentation, not realizing that back-end coding is often as necessary of a factor, not only in why the site appears as it does but in how the user accessed it initially. Coding is complicated and foreign to most, making the source code of a webpage unreadable to the average visitor. Still, the designers’ heavy lifting takes place in that same code and ultimately determines its success or failure. From HTML, CSS, JavaScript, Schema Markup, and more, codebase is a primary factor.

Code is not used only for website design but really for any kind of web or software development. Think about Facebook or iTunes. Each of these has a codebase that informs not only its presentation but also its functionality or usability. Coders are often the most technically sound webmasters in the room and can implement the average person’s elements. Although website builders have turned everyone into amateur designers, they have not familiarized everyone with coding, which is still what separates the legitimate professionals.


HyperText Markup Language (HTML) is the actual code used to write every website. HTML annotates text with tags, suggesting a browser to display it in a way that the designer intends. The language uses a series of tags that range from very basic to very complex. For example, text surrounded by a <strong> tag on the back-end is bolded on the front-end. HTML is closely associated with SEO since header, title, and meta tags are all part of the HTML language. A CMS like WordPress makes HTML alterations simpler from an SEO perspective, but the design itself still requires in-depth knowledge of the coding language.



Cascading Style Sheets (CSS) is code that instructs a browser on how to display HTML. While HTML tags suggest things like bolded text, the CSS code instructs the browser on what that will look like on the website’s front-end. CSS references what designers call rules. A CSS rule contains three parts; a selector, a property, and a value. More advanced CSS mechanisms like inline link CSS and internal CSS always play a role aside from CSS rules. The simplest way to describe the codebase is the stylization of HTML tags. CSS is very much related to the display presentation of a website, a concept outlined earlier.

CSS Code


JavaScript is a code language that provides interactivity to websites. When combined, HTML and CSS can formulate a custom webpage, but without JavaScript, it will remain static (it won’t move). The code of JavaScript makes a webpage respond to user events like hovering, clicks, or commands. Much like with CSS, JavaScript has inline, internal, and also external protocols. JavaScript can be an asset to website design but can also hinder it if misused. Bloated JavaScript is known to slow down websites and negatively influence site speed. For this reason, an expert coder should perform the implementation.

JavaScript Code

Schema Markup

Schema.org or Schema Markup is a vocabulary of semantically related tags inserted into HTML to help Google interpret the page. Microdata tags from Schema.org exist to help search engines like Google better categorize pages and subsequently promote them on search results. Schema is fundamental to SEO and is perhaps the most critical optimization element of a website’s codebase. Since schema comes from search engines’ instruction, we know that Google considers it when pages are crawled, indexed, and ranked.

Mobile Design 

The increased mobile usage of the average American has made mobile design more critical than ever before. Researchers estimate that over half of all HVAC website visitors will access the site through a smartphone. Because phones are accessible 24 hours per day, seven days per week, there is an infinite window of opportunity for contractors to reach their most extensive consumer base. SEO can drive traffic to your website and other web entities (Google Maps, Facebook, etc.), but a sales conversion remains unlikely without a simple website to use on mobile. 

Several design elements will be embellished or adapted to narrow the target in promoting services to a mobile user. One such example of this is a call to action. A CTA on a website for desktops might list an HVAC contractor’s phone number. On mobile design, it should have a clickable number to connect to your phone line directly. Because conversions are the goal of websites, CTA’s are crucial. Strategic CTA placement has never been more pertinent than in 2021 when mobile usage increases daily.

Mobile Layout

Screen size matters and smartphones have less space for users to operate. Pair that with low attention users, and you have yourselves one of the primary challenges of modern design. How can you, as a web developer, intrigue the mobile user through your website? You have limited time and space and must make the most of it. A layout should be instructive and straightforward while creating urgency for the visitor. A clear call to action with a clickable phone number is ideal. Other layout factors to consider include height, width, image and logo placement, and space.

Mobile Layout Example

Mobile Speed

Websites should load quickly regardless of device, but it is even more crucial on mobile. Sites that don’t load within 3 seconds will lose more than half of their visitors, a timeframe that has likely already decreased and will continue to with each passing day. Google’s tool, Test Your Mobile Website Speed, can give HVAC companies an idea of where they are currently and perhaps where they should be relative to other sites throughout the web. For contractors, the fear is that slow-loading pages will prompt visitors to try the next result.

Test Your Mobile Site Speed Screenshot

Mobile Call to Action

Web developers must tailor calls to action to the mobile user. The best example of this is a clickable phone number that can be a stylized button or text. The goal is to create urgency for the mobile user, so accompanying the phone number with a statement like a call now for a free consultation is something every contractor should consider. There’s a fine line between creating urgency and becoming overly sales-driven, and the most successful websites can navigate that terrain to generate high-quality leads.

Mobile Call To Action Example

Custom Design 

Wix, Weebly, and Squarespace help the average person create nice-looking websites. If they have a disadvantage, it is their lack of customization. Certain limitations come with using website builders that don’t exist when investing in a professional designer. While not every Wix site will look identical in presentation, the back-end codebase will be similar and less customizable. Site builders can hinder SEO efforts needed for a website to get traffic. As we’ve stated, website design cannot exist exclusively from SEO if increasing sales is the goal.

Besides custom codebase being a superior SEO protocol, customization is part of every aspect of design. From the placement of a logo on the page’s layout to the palette color scheme on the CSS style sheet, customization can go a long way towards increasing conversion rates and satisfying users’ needs and attention spans. It’s not to say that website creators cannot work under any circumstances, but instead highlight why custom design is so useful. It becomes the HVAC company’s choice based on its digital marketing goals.

Custom Codebase

Tools like Wix provide options for display. Website makers can choose their layout, buttons, and even color schemes. While this might differentiate one website from another, the code will remain similar. You see, even with a change in the color scheme which alters the existing CSS code, the skeleton of the style sheet stays identical. Google can identify Wix websites based on their internal codebase. It doesn’t make it a wrong choice, but it can make SEO a more complicated process to execute and ultimately discourage your coveted sales growth.

Custom Codebase Example

Complete Control

Tired of your website’s footer saying something like “designed with Weebly?” If so, custom design may be for you. With custom design, you control what appears on your website and where it appears. There are no mandatory insertions of code. Instead, you can add your logos, awards, and badges of honor to your header and footer. Customization = control for HVAC contractors. Consider something as simple as your logo widthwhich could be limited in Wix.

Company Branding

With genuinely custom web design, you can brand your HVAC company in a manner not replicable through website builders. A unique codebase, layout, and color scheme can differentiate your website from others in the same industry and service area. You may find the differences between a template website and a custom one to be minimal at first glance, but Google sees it differently. Perhaps most importantly, users growing accustomed to your brand through website design can only help expand awareness and foster a long-term, sustainable online presence.

Branded Website Example

Responsive Design 

We’ve noted that most visitors will access HVAC websites through mobile smartphones, but the highest conversion websites cannot ignore any of its users. That includes those who access the website on a desktop, tablet or another 3rd party device that is not a smartphone. Since it’s not plausible to design a site for each device, brand, and model, the best solution is responsive web design, sometimes shortened as RWD. The primary advantage of RWD is to optimize display and functionality for a website on any device efficiently and reach all possible customers.

Comparison Between Viewport Sizes

Mashable named 2013 the year of responsive design, and six years later, it is now considered the norm for websites that perform well on Google. The search engine has gone as far as to recommend its usage to web developers and has even offered RWD tutorials on their Web Fundamentals platform. RWD fixes would-be problems that designers would once dread. For example, an image displayed on a mobile site might appear too small on desktop, but responsive design incorporates flexibility and resizes the image to its optimal display.


The area immediately visible to users is known as the viewport. As you might imagine, viewports vary by device, so an iPhone 11 viewport won’t compare to a Dell PC monitor. Before mobile’s emergence, designs often focused on desktop viewing, which created viewport distortion on mobile. If you remember older mobile phones, you also remember some of the worst-looking websites of all time. Imagine trying to book a phone call with your local HVAC contractor using that display. It would be a disaster.

Mobile Viewport


Breakpoints are browser measurements declared to change the display based on a specified range. In responsive design, breakpoints usually adjust to the width of the screen. Sometimes a breakpoint might shift the viewport from displaying two columns to displaying four columns. Designers should focus on breakpoints by device rather than the model. In other words, smartphones should be a category, but Apple iPhone 11 should not be. Breakpoints’ significance also varies. Some of them can be quite obvious, while others are more subtle. Use tactfully.

Graphic Design (UX)

A website’s graphics are part of its visual presentation but can be considered an entirely different skill altogether from a designer’s standpoint. Graphics can be everything from logos to interactive buttons and everything in between. Graphics are often tied into a site’s color scheme but are not the color scheme itself. Most color palettes work from the starting point of the logo. If your HVAC company has an existing logo with brand recognition, you should maintain or enhance it. Brand new contractors might be looking for an original logo from a professional designer.

Logos are likely an essential graphic for a company but certainly not the only one needed on your website. As we said, graphic design is a skill that transcends web design. While websites use code and tags, visual artists use digital art studios such as Adobe Suite. IllustratorInDesign, and Photoshop can all help create graphics for your website and other marketing materials. Graphics can be published on print materials as well, such as business cards and newsletters. Contractors can also print graphics on t-shirts, truck wraps, and other marketing materials.

Logo Design

An effective heating & cooling logo is both simple and memorable. Striking that balance isn’t the easiest thing to accomplish. Still, the companies that thrive are the ones that find a balance. Focus on solid colors that are easy on the eyes. 99 Designs outlines what each color evokes from the perspective of the typical consumer. For instance, blue is one color that people often associate with trust and professionalism, making sense when you understand why it’s on at least half of all logos. Think about your logo for a moment; what characteristics does it evoke?

HVAC Logo Example


Its graphical outline often enhances a call to action. In other words, a phone number button might appeal more to the user than merely the number itself. Why? Because consumers love to be visually inspired. Since the goal of every CTA is to create urgency and prompt action, enhancing its graphical nature can help reach that destination. Enhancement assumes the graphic is skillfully designed, of course. Keep in mind that poorly designed graphics can harm a user’s behavior. CTA buttons are important when merging illustration and web design.


What is the information distributed on infographics? It can be anything and everything as long it stays within the context of your web pages and the content published on them. If CTA buttons merge graphic and web design, infographics unify content marketing, graphic, and web design. It’s a way of threading everything the user consumes together in one cohesive construct. Like with logos and buttons, an infographic can range from extremely helpful to discouraging. Some infographics become so popular; they earn inbound links to the image address, which helps SEO.

User Experience (UX)

We spoke about UI or user interface, but the most crucial part of a website is UX or user experience. Although it is less quantifiable, UX encompasses the overall experience of the website visitor. A visitor’s experience relates to everything previously discussed on this page, from aesthetics and visual presentation to navigation and website functionality. Of course, codebase remains the foundation of UX since it ultimately dictates it, even if the users themselves don’t realize it on a fundamental level. While a single metric cannot measure UX, there are groups of data that can paint a general picture of its performance, such as bounce rate, pages per session, etc.

Google understands website visitors’ behavior better than ever before and uses that information to inform their rankings. The sites that rank highest keep users actively engaged, which gets reflected in behavioral metrics. Whether it’s visiting multiple pages on a website or engaging with content elements on the homepage, users make their feelings apparent to Google in more ways than one. The goal of every HVAC website is to generate leads, and there’s no safer way to accomplish this than through enhancing the user’s experience and inspiring them to complete a call to action.

Behavioral Metrics

We can best understand UX through user metrics like bounce rate and pages per session. Although we can all subjectively visit an HVAC website and form an opinion on it, it is actions that demonstrate our most accurate conclusions. Any local service website that can keep users engaged and encourage participation in sales funnels and calls to action will benefit through metrics. The best way to track user behavior is through Google Analytics, a free tracking tool.

Google Analytics Screenshot

Website Feedback

Aside from measuring user behavior, asking them outright for feedback can also be helpful. While it doesn’t provide the kind of raw data that Google values, it does inform heating & cooling businesses about their site’s strengths and weaknesses, explained from a visitor’s perspective. Sometimes people will hold back on criticisms, but if you include an anonymous survey directly on your website, there’s little for them to hold back. You might even get criticism so harsh that you wonder if they’re intentionally combative in hopes of weakening your will as a contractor.

Repeat Visitors

Separate from the user’s behavior when first visiting your website, a telling piece of information can be the ratio by which visitors return. Sometimes brand notoriety can influence visitors to return to a site, again and again, something that should make itself apparent by the percentage of traffic reaching the site through a branded search or a direct visit. Other times more than brand recognition, it is about the site’s design and its UX quality. All the design elements discussed in this post can influence repeat visitations.

Affordability is always a consideration in marketing but what’s most important is ROI or return on investment. A website template might cost less upfront, but how much money is it going to bring in? If you don’t know the answer to that question, you should opt for a free SEO audit that quantifies your rank position based on call volume. Lack of calls on your site means you’re not ranking on either Google organic or Google Maps. If that’s the case, even the nominal investment you’ve made in a website template is a negative ROI. Keep in mind that our services are incredibly affordable for agency-level website design, so we are happy to discuss the details further with you at your convenience.
