Our standard installation includes mounting the indoor unit, installing the outdoor unit, connecting refrigerant lines, electrical wiring, vacuum testing, and commissioning. Installation kits with copper pipes, brackets, and drain hoses are available for purchase.

SEER (Seasonal Energy Efficiency Ratio) measures cooling output divided by energy consumption over a season. Higher SEER means greater efficiency. We recommend SEER 16+ for optimal savings. Units with SEER 20+ qualify for many energy rebates.

A heat pump transfers heat between indoor and outdoor air. In summer, it removes heat from inside your home. In winter, it extracts heat from outdoor air (even in cold temperatures) and brings it inside. This makes heat pumps 3-4x more efficient than traditional electric heaters.

Inverter ACs use variable-speed compressors that adjust cooling output based on room temperature, rather than cycling on and off. This results in up to 40% energy savings, more consistent temperatures, quieter operation, and longer compressor life.

Warranties typically do not cover damage from improper installation, neglect, unauthorized repairs, natural disasters, or normal wear and tear. Consumable items like filters are also not covered. Review the specific warranty document for complete exclusions.

R-32 has a lower global warming potential (GWP) than R-410A, making it more environmentally friendly. It also offers better energy efficiency. R-410A is still widely used and reliable. Both are effective refrigerants; R-32 represents the newer, greener standard.

We offer a 30-day hassle-free return policy. If you're not completely satisfied with your purchase, you can return it within 30 days for a full refund. The product must be in original condition with all packaging and accessories included.

Most residential units up to 14,000 BTU run on standard 115V. Units from 18,000-36,000 BTU typically require 208-230V. Check the product specifications for exact voltage requirements and consult an electrician if you're unsure about your home's electrical capacity.

All products come with the manufacturer's standard warranty, typically 1-2 years on parts and 5 years on the compressor. Extended warranty options up to 5 years total coverage are available for purchase. Warranty terms vary by brand and are listed on each product page.

Refunds are processed within 3-5 business days after we receive and inspect your return. The refund will be credited to your original payment method. Please allow an additional 5-10 business days for the refund to appear on your statement depending on your bank.

Water leakage is usually caused by a clogged condensate drain line, dirty filter restricting airflow, or improper installation angle. Try cleaning the filter and checking the drain hose. If the problem persists, contact our support team for troubleshooting assistance.
