Terms of Service

Last updated August 18, 2026

These terms govern services provided by National Install Service LLC, doing business as National Install Service ("we," "us"). By requesting or accepting an estimate, scheduling work, or paying an invoice, you ("you," "customer") agree to these terms.

1. Services we provide

We are an installation and service contractor. We perform heating and air conditioning, plumbing, electrical, and manufactured home hookup work at the customer's property. All work is labor and installation. We do not sell standalone products, and we do not ship goods. Equipment and materials are sourced for a specific job and installed by our technicians as part of that job.

2. Estimates and quotes

Written estimates for installation and replacement work are provided at no charge. Diagnostic and troubleshooting visits carry a flat service fee disclosed before we dispatch a technician.

A quote is valid for thirty (30) days from the date issued. Quoted prices assume conditions observed at the time of assessment. If concealed conditions are found once work begins, such as damaged framing, non-compliant existing wiring, or failed underground lines, we will stop, document the condition, and issue a change order for your written approval before continuing. You are not charged for additional work you have not approved.

3. Scheduling and access

You agree to provide safe and lawful access to the work area and to the property's utility connections at the scheduled time. If our crew arrives and cannot access the property, or if the site is not ready for the scheduled work, a trip charge may apply.

4. Permits and inspections

Where the governing authority requires a permit, we pull the permit and coordinate inspection unless the estimate states otherwise. Permit and inspection fees are itemized in the quote. We are not responsible for delays caused by the permitting authority or by an inspector's schedule.

5. Payment terms

Prices are in US dollars. We accept Visa, Mastercard, American Express, Discover, ACH bank transfer, check, and cash.

• A deposit is due at scheduling when equipment or materials must be ordered for your job.
• The remaining balance is due upon completion of the work.
• Invoices are delivered by email with a secure payment link.
• Balances unpaid thirty (30) days after the invoice date may accrue a late charge of 1.5% per month or the maximum rate permitted by law, whichever is lower.

6. Cancellation and refund policy

Cancelling scheduled work

• You may cancel or reschedule any appointment at no charge by giving us at least twenty-four (24) hours' notice before the scheduled arrival window.
• Cancellations inside twenty-four (24) hours, or a missed appointment where the crew cannot access the property, may be charged the flat service fee.

Deposits

• If you cancel before we have ordered equipment or materials for your job, your deposit is refunded in full.
• If you cancel after equipment or materials have been ordered, we refund the deposit less the non-recoverable cost of those items, including any supplier restocking charge. We will show you the supplier documentation for any amount withheld.
• If we cancel a job for any reason, or cannot complete the work as quoted, your deposit is refunded in full.

Completed work

Because our work is labor performed and equipment permanently installed at your property, completed installations are not returnable. If you are not satisfied with completed work, contact us within thirty (30) days and we will inspect the work. Where the issue falls within our workmanship warranty, we will correct it at no charge. Where a repair is not practical, we may issue a partial or full refund of the labor charge at our discretion.

How to request a refund

Call (843) 665-1915 or email ar@nationalinstallservice.com with your invoice number and a description of the issue. We respond to refund requests within three (3) business days and issue approved refunds to the original payment method within ten (10) business days.

7. Workmanship warranty

We warrant our labor and installation against defects in workmanship for one (1) year from the date the work is completed, unless the quote states a longer term. Equipment and materials carry the manufacturer's warranty, which we register in your name and pass through to you. We will support a manufacturer warranty claim on your behalf.

This warranty does not cover:

• Damage from misuse, accident, vandalism, flood, fire, storm, or power surge.
• Failure caused by lack of routine maintenance.
• Work altered, serviced, or repaired by anyone other than our technicians.
• Pre-existing conditions in systems we did not install, unless we specifically warranted them in writing.

8. Limitation of liability

To the fullest extent permitted by law, our total liability arising out of any job is limited to the amount you paid us for that job. We are not liable for indirect, incidental, or consequential damages, including loss of use, lost income, or property damage not caused by our negligence. Nothing in these terms limits liability that cannot be limited under applicable law.

9. Customer responsibilities

• Disclose known hazards at the property, including asbestos, lead paint, unmarked utility lines, and structural damage.
• Secure pets and remove personal property from the work area before the crew arrives.
• Confirm you have authority to authorize work at the property, or provide written owner consent.

10. Disputes and governing law

These terms are governed by the laws of the State of South Carolina. Before filing any claim, you agree to contact us and allow thirty (30) days to resolve the matter directly. If you paid by card, please contact us before initiating a chargeback so we can address the issue.

11. Changes to these terms

We may update these terms. The version posted on this page at the time your quote is accepted governs that job.
