In this crossover episode (rantcast), Bryan talks with Gary from HVAC Know It All. They vent about some of the phrases that techs throw around that are often false.

Technicians often throw around the phrase, "[X] will void your warranty." However, the truth is that manufacturers can't really void a warranty. Some modifications may go beyond the scope of the warranty, but you don't simply make modifications that "void" the warranty. Techs may say that something voids the warranty to shut down the conversation or to create a selling point (preventive maintenance).

In many (but not all) cases, the manufacturer won't even check the installation in the case of a parts warranty; all they want is the returned part, and they will often honor the warranty. Since many manufacturers want to keep their customers, voiding warranties left and right would be a bad business decision; the customer base would opt to work with new manufacturers.

However, if there is evidence that the customer, installer, or technician damaged the product, then the manufacturer has a reason to void the warranty. In several cases, the proof must be substantial, and the proof often isn't substantial when using natural additives like Nylog properly. Keep in mind that using additives comes with a calculated risk; you must rely on research and your own judgment to make the best decision for the customer.

In this rantcast, Gary and Bryan also discuss:

• R-22 is not illegal
• Heat exchanger warranties
• Lightning and other "acts of God"
• The Nylog question
• Why use thread sealants on well-made flares
• Relationships with manufacturers and suppliers
