Customer Questions
What happens if it arrives damaged?
If you are present during drop-off and you see obvious signs of damage or rough handling in transit - please ask the driver to wait while you inspect the equipment. If it is damaged badly enough that you believe it can not function, you have the right to refuse the damaged portion of the shipment. If you discover the damage after the driver has left, take photos of the damage and send them to customerservice@hvacdirect.com. Please refer to your order number in the email. This starts the process and one of our representatives will be in touch with you promptly.
How can I find an installer?
It’s easier than you think – the key is to find an independent contractor or small company as opposed to a larger HVAC service. A one or two person outfit will do the work more quickly and cheaply than a bigger company, too. Yelp.com, Thumbtack.com, and Porch.com are websites are designed to help you connect with a professional in your area. You could also place a call to the last professional who did work on your home and see if they have any recommendations.
Who makes Carrier mini splits?
Carrier mini splits come from one of the most recognized names in HVAC, offering reliable, energy-efficient solutions for year-round comfort.
Can I install a Carrier mini split myself, or do I need a professional?
Carrier mini splits require professional installation. A licensed HVAC contractor ensures proper sizing, refrigerant handling, and warranty protection.
What kind of warranty comes with a Carrier mini split?
Most Carrier mini splits include a 10-year limited parts warranty when registered, giving you long-term peace of mind. Warranty terms may vary by model and installer.
