What should an HVAC or contractor website include in DC, Maryland and Virginia?

An HVAC or contractor website in DC, Maryland and Virginia needs one page per service, service-area pages with local facts, a tap-to-call number, real job photos and genuine reviews. It also needs your license numbers in the form each jurisdiction expects, and financing wording that meets federal credit-ad rules. Generic checklists miss those last two.

We checked each rule below at its official source on October 13, 2026. This is general information, not legal advice.

What should every HVAC or contractor website include?

Start with the basics, and test each one with our guide to sites with visitors but no calls.

• One page per service. AC repair, furnace replacement, heat pumps, water heaters and maintenance plans each get a page that says what's included, where you work and how to book. That page is also where your ads for the service should land.
• A tap-to-call number at the top of every page, as text, with your hours beside it. Promise emergency service only if someone answers at night.
• Real job photos: your installs, your trucks, and before-and-after shots labeled with the town. Stock photos prove nothing.
• A short quote form: name, phone, ZIP code, the service and how soon.
• Your license numbers, in the forms covered below.
• Current badges only. Google replaced the Google Guaranteed badge with Google Verified from October 2025 (Google, August 2025). If your site still shows the old badge, update it.

How do you show reviews without breaking the rules?

Ask every customer for a Google review, and link to your profile from your site. Google bans offering "payment, discounts, free goods and/or services" for reviews. It also bars businesses from trying to "selectively solicit positive reviews", so ask everyone, not only happy customers (Google Maps content policy, October 2026).

Testimonials on your own site are advertising. The FTC's reviews rule took effect on October 21, 2024. FTC staff say a business can be liable for fake or false testimonials on its website (FTC, November 2024). Use real customers' words, with permission.

Should you build a page for every town you serve?

Only where you have something real to say. Google's spam policies list as doorway abuse "pages targeted at specific regions or cities that funnel users to one page" and "substantially similar pages that are closer to search results than a clearly defined, browseable hierarchy" (Google Search Central, October 2026). Fifty copies with the town name swapped fit that description.

Here, a useful area page has facts that change across the border:

• The license that applies there: your MHIC or Maryland HVACR number on Maryland pages, your DC license on the DC page, your Virginia license and class on Virginia pages.
• Jobs you've done there, with photos and the owner's permission.
• Local details, such as your permit office.

What does Maryland require?

Home improvement contractors. An ad that says you're licensed must state the number as "Maryland Home Improvement Commission License No. _____" or "MHIC No. _____" (Md. Code, Business Regulation § 8-615). The Commission says "each home improvement advertisement must contain the name and license number of the contractor" (MHIC). Its February 2021 bulletin says advertising includes "company websites, social media sites" (Maryland Department of Labor, 2021).

Maryland's advertising regulation also shapes your offers (COMAR 09.08.01.09):

• A coupon can't require the customer to show it before you give an estimate.
• If a price leaves out items the job needs to work and look right, say so next to the price. State extra delivery or installation charges clearly.
• If you mention a warranty, state its terms, limits and length.

HVACR contractors. "Each printed, audio, or video advertisement of any type, and all contracts" must show the license category and number of the licensee responsible for the work. The form is "Md.—HVAC—category prefix—license number", with .01 for a master, .02 for a master restricted and .06 for a limited license (COMAR 09.15.02.03). The rule doesn't name websites, but the same form in your footer costs nothing.

What do DC and Virginia require?

DC. A licensed home improvement contractor "may advertise in any manner", but "in any advertisement, the licensee shall include his or her license number" (16 DCMR § 807.1).

Virginia. We found no statewide rule that puts a license number in ads. The Board for Contractors bans any contracting ad that is "false, deceptive, or misleading", and residential contracts must list your license number, class and specialties (18VAC50-22-260). Board guidance adds that a business name "cannot reflect work that the contractor is not licensed to perform" (Board for Contractors guidance, December 2025). Hold your service pages to the same standard: list only work your license covers.

Type each license on its own line in the site footer, as text, not inside an image. Repeat it on your contact page with a link to the state's license lookup, and beside your quote form.

What can you say about financing?

Federal credit-ad rules apply to you even when a lender makes the loan. Regulation Z's ad rules cover "home builders, merchants, and others who are not themselves creditors" (CFPB, Regulation Z commentary).

For loans with a set number of payments, 12 CFR 1026.24(d) lists four triggering terms: the down payment, the number of payments or repayment period, the amount of any payment, and the amount of any finance charge (CFPB, Regulation Z § 1026.24). Use one, such as the CFPB's own examples "$25 weekly" or "48-month payment terms", and the ad must also state the down payment, the repayment terms and the "annual percentage rate". A plain "Ask about financing" states none of the four.

If the lender offers a credit card or other revolving account instead, 12 CFR 1026.16 applies. There, even "no interest" triggers extra disclosures, and deferred-interest offers have their own rules (CFPB, Regulation Z § 1026.16). Ask your lender which section applies, and use its approved wording.

Frequently asked questions

Does a Maryland HVAC company need its license number on its website?

Maryland's HVACR rule covers "each printed, audio, or video advertisement of any type" and all contracts. It doesn't name websites. Showing your license category and number in the required form in your site footer is the safe choice. This is general information, not legal advice.

Do Virginia contractors have to show a license number in ads?

We found no statewide Virginia rule that requires it. The Board for Contractors bans false or misleading contracting ads and requires your license number and class on residential contracts. Showing both on your site lets homeowners check you before they call.
