Lifetime Workmanship Guarantee Terms & Conditions

We stand behind the quality of our HVAC installation work.  Our Lifetime HVAC Workmanship Guarantee covers certain defects in the workmanship of qualifying HVAC installation work performed by Day & Night.

If a covered installation defect occurs as a result of our workmanship, we will, at no charge for labor, correct the workmanship defect using reasonable methods and materials necessary to restore the affected installation to proper operating condition.

This guarantee is intended to cover our workmanship—not equipment failure, manufacturer defects, maintenance, pre-existing conditions, or conditions outside the scope of our work.  Equipment and component failures are generally governed by the applicable manufacturer’s warranty.  Lifetime Workmanship Guarantee is NOT the same as Lifetime Equipment Warranty.

1. What Is Covered

Subject to these Terms & Conditions, this guarantee covers HVAC installation work performed by Day & Night when the failure is directly and primarily caused by defective workmanship.

Examples of potentially covered workmanship defects include:

  • Improper refrigerant-line connections or brazing performed by us;
  • Improperly installed or terminated electrical wiring performed by us;
  • Improperly installed condensate drains or drain components installed by us;
  • Improperly installed equipment;
  • Improperly installed ductwork, fittings, transitions, or connections that were part of our contracted scope of work;
  • Improperly sealed or connected air-distribution components installed by us;
  • Improperly installed gas piping or combustion-related components that were within our contracted scope of work;
  • Improper installation of equipment controls or low-voltage wiring;
  • Installation defects that cause the HVAC system to malfunction and that are directly attributable to our workmanship.

The determination of whether a condition constitutes a workmanship defect will be made based on the applicable installation requirements, manufacturer installation instructions, applicable building codes, and generally accepted HVAC installation practices applicable to the work performed.

2. What “Lifetime” Means

For purposes of this guarantee, “Lifetime” means the lifetime of the original purchaser while the original purchaser owns and occupies the property at which the qualifying HVAC system was originally installed.  Unless otherwise stated in writing, this guarantee:

  • Is provided to the original purchaser;
  • Applies only to the original installation address;
  • Does not transfer to a subsequent property owner;
  • Does not continue after the original purchaser sells or transfers ownership of the property. 

3. Workmanship vs. Equipment Failure

This guarantee covers workmanship defects. It does not constitute a lifetime warranty on the HVAC equipment, components, or materials themselves.

4. Labor Associated With Manufacturer Warranty Repairs

This guarantee does NOT make Day & Night responsible for labor associated with replacing a component that fails due to a manufacturer defect. If a manufacturer warranty covers a failed component, the manufacturer’s warranty terms determine what is covered.  However, if the failure of the component is directly caused by defective workmanship, the applicable corrective work may be covered.

5. Existing Conditions Are Not Covered

This guarantee does not cover conditions that existed before our installation or that was/is outside our contracted scope of work.  If an existing condition contributes to an HVAC problem, the existence of our workmanship guarantee does not make Day & Night responsible for correcting that pre-existing condition unless that corrective work was specifically included in our original written scope of work.

6. Scope of Work Controls

This guarantee applies only to work that Day & Night was contractually responsible for performing.

If a particular component, system, modification, repair, duct alteration, electrical modification, structural modification, or other improvement was not included in the signed proposal, estimate, invoice, or scope of work, it is not covered merely because it affects the operation of the HVAC system.  The customer’s signed contract and applicable change orders determine the scope of work covered by this guarantee.

7. Maintenance Is Not Workmanship

Routine maintenance and owner-maintained items are not covered by this guarantee.  Failure to perform routine maintenance does not necessarily void this guarantee in its entirety. However, Day & Night is not responsible for a condition to the extent that the condition was caused or materially contributed to by inadequate maintenance.

8. Unauthorized Repairs or Modifications

This guarantee does not cover defects, damage, or failures caused by repairs, alterations, modifications, adjustments, or other work performed by anyone other than Day & Night or a person expressly authorized by Day & Night in writing.  If another party modifies or repairs our installation, Day & Night may require an inspection of the affected work before determining whether a subsequent claim is covered.

9. Damage, Misuse, and Abnormal Conditions

This guarantee does not cover damage or failure resulting from:

  • Abuse;
  • Neglect;
  • Misuse;
  • Improper operation;
  • Accidental damage;
  • Vandalism;
  • Fire;
  • Flooding;
  • Lightning;
  • Power surges;
  • Electrical disturbances;
  • Utility failures;
  • Acts of nature;
  • Severe weather;
  • Pest or animal damage;
  • Freezing;
  • Water damage unrelated to our workmanship;
  • Corrosive environmental conditions;
  • Unauthorized modifications;
  • Any other condition outside the reasonable control of Day & Night.

10. Changes to the Property

This guarantee does not cover problems caused by changes made to the property after our installation.

Examples include:

  • Home additions;
  • Room additions;
  • Remodeling;
  • Changes to walls, doors, windows, or ceilings;
  • Changes to insulation;
  • Changes to ductwork;
  • Changes to building occupancy or use;
  • Changes to electrical service;
  • Changes to gas service;
  • Changes to zoning;
  • Changes to the building envelope;
  • Installation of new appliances or equipment that materially changes the home’s heating or cooling load.

If a property modification changes the conditions under which the HVAC system operates, Day & Night is not responsible for resulting performance problems unless the corrective work is separately contracted.

11. Comfort and Performance Are Separate From Workmanship

This guarantee is not a general comfort or performance guarantee.  A system may experience comfort or performance issues for reasons unrelated to workmanship.  Unless expressly stated in a separate written performance or comfort guarantee, such conditions are not covered by this Lifetime Workmanship Guarantee.

12. Diagnostic and Service Visits

If a customer reports a condition believed to be covered by this guarantee, Day & Night may inspect and diagnose the condition.  If the inspection determines that the reported problem is caused by a covered workmanship defect, Day & Night will perform the covered corrective work at no charge for labor.  If the inspection determines that the condition is not caused by a covered workmanship defect, the customer may be responsible for applicable diagnostic, service, repair, travel, or other charges disclosed before the work is performed.  Day & Night will not charge the customer for correcting a confirmed workmanship defect covered by this guarantee.

13. Reasonable Opportunity to Correct

Before any other remedy is considered, Day & Night must be given a reasonable opportunity to inspect and correct a claimed workmanship defect.  Day & Night may determine the appropriate corrective method based on the nature of the defect.  The customer’s preferred method of repair does not control the remedy.

14. No Guarantee of Unrelated Components

This guarantee does not extend to components, materials, equipment, or systems Day & Night did not install or modify.

15. Cosmetic Conditions

This guarantee covers functional workmanship defects, not ordinary cosmetic conditions.  Unless specifically included in the original scope of work, the guarantee does not cover:

  • Paint;
  • Drywall;
  • Texture;
  • Stucco;
  • Roofing;
  • Flooring;
  • Cabinetry;
  • Trim;
  • Cosmetic imperfections;
  • Minor scratches or dents;
  • Normal appearance variations.

Damage directly caused by negligent workmanship may be addressed separately according to applicable law and the terms of the original contract.

16. Code Changes After Installation

This guarantee applies to the work based on the applicable requirements at the time the work was performed.  Day & Night is not responsible for bringing a previously compliant installation into compliance with building codes, regulations, manufacturer requirements, or standards that are adopted or changed after the original installation, unless required by applicable law.

17. Access to the Property

To obtain service under this guarantee, the customer must provide Day & Night reasonable access to the property and affected equipment.  The customer is responsible for ensuring safe and reasonable access to equipment.  Additional charges may apply for extraordinary access requirements.

18. Claim Procedure

To request service under this guarantee, the customer should contact Day & Night at 602-956-9404. 

Customers should notify Day & Night promptly after discovering a suspected workmanship defect.

19. Transferability

Unless specifically stated otherwise in writing, this guarantee is not transferable to a subsequent owner of the property.  Any transfer approved by Day & Night must be completed in writing before the property changes ownership.

20. No Cash Value

This guarantee provides a commitment to correct qualifying workmanship defects.  It does not have a cash value and does not create a right to a cash payment instead of corrective work.  Except where otherwise required by applicable law, Day & Night’s obligation under this guarantee is limited to correcting the covered workmanship defect.

21. No Consequential or Incidental Damages

To the maximum extent permitted by applicable law, Day & Night is not responsible under this guarantee for indirect, incidental, special, consequential, or economic damages arising from an alleged workmanship defect.  Examples may include:

  • Loss of use;
  • Increased utility costs;
  • Lost income;
  • Hotel or lodging expenses;
  • Business interruption;
  • Personal inconvenience;
  • Loss of food;
  • Damage to personal property;
  • Other consequential losses.

Nothing in this section is intended to waive or limit any rights or remedies that cannot legally be waived or limited.

22. Relationship to Manufacturer Warranties

This guarantee is separate from and in addition to applicable manufacturer warranties.  Manufacturer warranties may cover equipment or component defects, while this guarantee covers qualifying workmanship performed by Day & Night.  Customers should retain all manufacturer warranty documentation and comply with applicable registration, maintenance, and claim requirements.

23. Relationship to Applicable Law

This guarantee is a voluntary warranty provided by Day & Night and does not waive, eliminate, reduce, or replace any rights or remedies that the customer may have under applicable federal, state, or local law.

Nothing in these Terms & Conditions is intended to limit any non-waivable rights or remedies available to the customer.  For Arizona installations, nothing in this guarantee is intended to limit applicable rights or remedies relating to the Arizona Registrar of Contractors or applicable Arizona construction, licensing, warranty, or consumer-protection requirements.

24. Entire Workmanship Guarantee

These Terms & Conditions, together with the customer’s signed proposal, contract, applicable change orders, and any written guarantee specifically identified as part of the customer’s transaction, constitute the complete terms of the Lifetime HVAC Workmanship Guarantee.  Any representation concerning this guarantee that is inconsistent with these written terms must be approved in writing by an authorized representative of Day & Night.
