In 2026, HVAC warranties in Philadelphia generally fall into three distinct categories: manufacturer, contractor-labor, and independent home service plans. Understanding the differences is critical, as many manufacturers have recently tightened “maintenance compliance” standards, requiring documented proof of annual professional service to keep warranties valid.

1. Manufacturer Equipment Warranties

These cover the physical parts of your system against defects but almost never cover the cost of labor.

  • Standard Terms: Most major brands (Trane, Lennox, Carrier) offer a 5-year base warranty that typically extends to 10 years if the product is registered within a specific timeframe (often 60 days) after installation.
  • Premium Options: Brands like Daikin and Goodman are currently recognized for some of the most extensive part-replacement terms on the market. 

2. Contractor-Labor Warranties

These are provided by the local Philadelphia company that installs your unit. They fill the gap left by manufacturers by covering the “trip charges” and hourly labor for repairs

3. Home Service & Warranty Plans

In Philadelphia, these are often separate annual contracts that cover aging systems not protected by original manufacturer warranties.

Important Comparison Tips for 2026

  • Registration is Mandatory: Failing to register a new system online can shorten a 10-year warranty to 5 years instantly.
  • Document Your Maintenance: Manufacturers like Trane and Mitsubishi now require “Evidence of Service” (professional receipts) to honor part replacements in 2026.
  • Labor Gaps: Be aware that a “10-year warranty” from a manufacturer will still cost you $200–$600 in labor fees per repair visit if you do not have a corresponding labor warranty from your Philadelphia HVAC contractor.
