New single-zone mini-split units deliver high-efficiency, reliable heating and cooling backed by dedicated U.S. customer support.
Philadelphia, PA – From hard-to-cool room additions and homes without ductwork to inefficient older systems, homeowners face ongoing challenges maintaining year-round comfort. Keystone Products, a trusted leader in home comfort solutions, announces its official entry into mini splits, delivering targeted, single-zone heating and cooling designed to eliminate hot and cold spots while reducing energy consumption.
Designed for easy professional installation, Keystone's new mini split systems combine advanced heat pump technology, ultra-quiet performance, and a dedicated U.S.-based technical support network, to deliver immediate comfort where it’s needed most.
"Homeowners shouldn't have to tolerate rooms that are perpetually drafty or overheated simply because extending traditional ductwork is too expensive or impractical," said William Munger, Customer Service Manager at Keystone Products. "Our new mini split series brings reliable, affordable, whisper-quiet heating and cooling right where it’s needed, giving families precise room-by-room control while helping lower their monthly energy bills."
Product Options Designed for Size, Efficiency, and Budget Needs
Keystone’s new mini split line features two distinct series designed to match any room size, energy goal, or budget. With cooling capacities spanning 9,000 to 24,000 BTUs, homeowners can easily find the perfect match for spaces ranging from small bedrooms and home offices to large basements, additions, and open living areas.
Both series utilize advanced heat pump technology, transferring heat rather than generating it, and varying motor speed to match demand, which drastically reduces power consumption for long-term operational savings compared to standard systems.
To help gauge energy savings, both series utilize SEER2 (Seasonal Energy Efficiency Ratio 2) ratings, the updated industry standard where higher numbers signify greater efficiency and lower energy bills.
- The Core Series ($699 – $1,099): Built for budget-conscious homeowners seeking high quality with lower upfront costs, the Core Series delivers dependable everyday performance with 20 to 21 SEER2 efficiency.
- The Summit Series ($799 – $1,499): Engineered for maximum energy reduction, the Summit Series elevates performance to 23 to 24 SEER2 efficiency and carries full ENERGY STAR® certification for optimal operation in moderate climates.
Whisper-Quiet Operation and Integrated Smart Features
Keystone mini splits feature multiple fan speeds that balance airflow power and sound levels. In Mute Mode, operational sounds drop as low as 28 decibels (dBA), or quieter than a soft whisper, ensuring bedrooms, nurseries, and home offices remain completely undisturbed. At max output, Turbo Speed reaches just 45 dB, keeping noise lower than moderate rainfall.
Every system provides multi-mode versatility (cool, heat, dehumidify, or fan-only) and comes standard with key features:
- Integrated Wi-Fi & App Control: Simple remote control via the Keystone App, plus voice compatibility with Amazon Alexa and Google Assistant.
- Temperature Sensing Remote: A smart remote control that measures temperature right where you are sitting, rather than just at the wall unit.
- Sleep & Timer Functions: Automated control to set schedules and gradually adjust temperature overnight for deeper, more efficient rest.
- Turbo Mode: Quickly reaches your desired temperature for rapid cooling or heating.
- Filter Alert: Automatic reminder ensures peak efficiency and air quality by notifying you when maintenance is needed.
Easy Delivery, Professional Setup & Lasting Protection
To simplify logistics from order to installation, each system includes one outdoor condenser/compressor unit, one indoor air handling unit that mounts on the wall, ceiling or floor, and a 16-foot line set. The complete systems ship parcel in two compact packages and arrives ready for professional installation.
Systems are backed by strong warranty protection, featuring a 7-year compressor warranty on the Core Series and a 5-year parts warranty on the Summit Series. Homeowners also receive direct access to dedicated, U.S.-based customer support (Monday through Friday, 9 AM – 5 PM EST) via phone, email, and live chat.
"Today’s homeowners are more informed than ever when selecting products for their home projects," said Munger. "We’re seeing a growing trend of 'Buy It Yourself' (BIY), where consumers actively research every detail online to choose the exact equipment for their needs, then hire a professional contractor for the installation."
Keystone Mini Splits are available online through select retail partners, including Amazon. For more information visit https://keystone-products.com/.
