The 500-Pound Box Dilemma

Thousands of Valley homeowners are buying brand-new systems and mini-splits online directly to save money. But when a freight truck drops a 500-pound box in your driveway and you call local HVAC shops to hook it up, they hang up on you. Why? Because traditional contractors refuse to touch iron unless they can slap a massive markup on the equipment first.

The Voided Warranty Trap

Out of frustration, many homeowners hire an unlicensed buddy or handyman to install the equipment. This is a massive mistake. Almost every major HVAC manufacturer will instantly void your 10-year warranty if the system is not installed by a licensed contractor. If the installer does not pull a proper 500-micron vacuum or braze the copper lines with nitrogen, that brand-new compressor will fail prematurely.

Frequently asked questions

Will traditional HVAC companies install an AC unit I bought myself?
Most traditional HVAC companies refuse to install customer-supplied equipment because they rely on marking up the price of the unit by thousands of dollars to cover their commissions and overhead.
Does installing my own AC void the warranty?
Yes. If your HVAC system is not installed by a licensed contractor, the manufacturer will typically void the 10-year parts warranty. A licensed professional must provide documented proof of installation.
