Website information
The public website gives general information and planning guidance. Do not treat page copy, an estimate, planner result or stated timeframe as confirmation of price, availability, technical suitability or a booking. A site assessment and written quote may still be required.
Customer accounts and requests
You may use the secure portal to create an account, add properties or sites, submit installation, repair or maintenance requests, exchange messages, upload permitted images and view service records. Keep your email access and devices secure, provide accurate information, and tell us promptly if an account member or contact should no longer have access.
Only upload images you own or are authorised to share. Do not upload unlawful, harmful or irrelevant content, payment credentials, identity documents or customer PDFs. We may reject or remove material that creates a security, legal or operational risk.
Appointments
An appointment shown as proposed is not booked until the customer confirms it and the portal records confirmation. A reschedule or cancellation request does not change the appointment until 21Aircon confirms the change. Access details must be accurate and a responsible contact must be available where the visit requires one.
Quotes and acceptance
Each quote revision is separate. The portal records the exact revision, total, applicable terms version, accepting person's name and authority, and acceptance time. Expired, withdrawn or superseded revisions cannot be accepted. The acceptance control states the total payment obligation; do not accept unless you are authorised and agree to pay that amount under the attached terms.
Quote-specific scope, assumptions, exclusions, deposit, payment schedule, cancellation rights, warranties and other contract terms take precedence over this general online-use page. Additional work or a variation requires a new written quote or variation; attendance alone is not consent to extra charges.
Invoices and payment links
Xero is the accounting source of truth for invoice numbers, tax records, balances, payments and credit notes. The portal may mirror that information and link to an approved external payment page. 21Aircon's portal does not collect card details, bank-login credentials or Direct Debit credentials.
Before any work is agreed
- Check that the quote and contract identify Techzura Ltd trading as 21Aircon and show the applicable contact details.
- Obtain a written description of equipment, labour, exclusions, access requirements, making good, total price, taxes, deposit and payment dates.
- Obtain the proposed dates, change-control process and what happens if hidden site conditions or additional work are identified.
- Obtain the exact manufacturer and workmanship warranty scope, duration, exclusions and claim route.
- Obtain the cancellation, cooling-off, complaint and dispute-resolution information that applies to the booking before accepting it.
Maintenance plans
One-off maintenance may be quoted under the applicable consumer or business terms. A service plan is not bought from a generic website checkout: customers can ask about a plan, and 21Aircon may prepare an exact offer for eligible, identified equipment inside the secure portal.
A service-plan offer remains a draft until the authorised customer accepts its specific plan revision and maintenance-terms version. The offer must state the covered equipment, included visits, price and VAT, billing period, start and renewal dates, exclusions and cancellation arrangements. The active agreement, covered systems, next visit and current terms then remain available in My21Aircon.
Complaints
Send the issue, relevant reference and outcome you are seeking to hello@21aircon.com, or call 01635 534810. Contract-specific complaint and dispute information will appear in the applicable approved terms. Nothing on this page limits statutory consumer rights.

Status
Online-use information updated 24 July 2026. This page is not the B2C, B2B or maintenance contract used to accept paid work. Owner-approved audience terms, maintenance terms and consumer early-start wording are versioned in the portal, which fails closed unless the exact active terms are attached to the relevant quote or plan offer. External professional review remains outstanding.
