What Happens If My New System Does Not Work After Installation?

Reviewed by AC Direct Technical Team Updated June 6, 20263 min read
The short answerHave a local licensed contractor diagnose the system. Many startup issues come from an adjustment or wiring detail and should be addressed first by the installer. If a covered part failed, that part is claimed through the manufacturer warranty or an authorized distributor. AC Direct ships the equipment but does not service systems or supply warranty parts.

Have the installer check the work first, then claim any covered part.

Start with the installer

If a new system does not run correctly right after installation, the first step is to have a licensed professional diagnose the problem. Many initial issues are not a failed part at all. They come from an improper adjustment, a wiring detail, a thermostat setting, or a startup step that needs correcting. The installer who set up the system is the right person to review the work and confirm everything was connected and configured as the manufacturer intended.

If a part actually failed

When a contractor confirms that a covered component failed, that part is handled under the original factory warranty. The contractor identifies the specific part and claims it through the manufacturer warranty or an authorized distributor for your brand. This is the standard path for Goodman, MRCOOL, ACiQ, Mitsubishi, Daikin, and other brands AC Direct carries. The manufacturer supplies the covered part, and labor to install it is billed separately by your contractor.

What AC Direct can and cannot do

AC Direct sells and ships complete HVAC equipment. We do not install, service, or repair systems, and we do not stock, supply, or replace parts. If a covered part fails, our support team can point you to the manufacturer warranty process and confirm the details of the equipment you purchased so your contractor can file the claim correctly.

Common questions

Should I call AC Direct or the installer first?
Start with the installer who set up the system. Many startup problems are an adjustment or wiring detail and are corrected on site. AC Direct support can then point you to the manufacturer warranty process if a covered part failed.
Are replacement parts free under warranty?
A covered part is supplied by the manufacturer under the original factory warranty, claimed through the manufacturer or an authorized distributor. Labor to diagnose and install the part is billed separately and is not covered.
Does AC Direct send the replacement part?
No. AC Direct ships complete equipment but does not stock, supply, or replace warranty parts. A covered part is claimed through the manufacturer or an authorized distributor, usually filed by your local licensed contractor.
