We proudly serve Barrington, IL, and Northwest Chicago, covering areas such as:
A ductless mini-split system provides heating and cooling using an outdoor condenser and one or more indoor air handling units. Instead of using ductwork, it moves refrigerant directly to the indoor units, which deliver conditioned air to individual rooms or zones. Each air handler is controlled independently, giving you zoned temperature control throughout your home.
Installation costs vary based on the number of zones, system brand, and complexity of the layout. In Barrington, IL, most homeowners spend between $3,500 and $10,000, depending on whether they're installing a single-zone system or a whole-home multi-zone configuration. RJ's provides detailed, upfront estimates and offers financing options for added flexibility.
For homes without existing ductwork or where energy use is a concern, mini-splits offer versatility and cost savings that traditional HVAC systems can't match.
Yes—especially modern inverter-driven models from brands like Daikin and Samsung. These units are designed to provide heat even when outdoor temperatures fall below freezing. For Barrington's winter climate, we recommend systems rated for cold-climate performance, often with built-in backup heat modes.
With proper maintenance, ductless systems typically last 15 to 20 years. Routine filter cleaning and annual inspections help extend system life. RJ's offers ongoing maintenance plan options to keep your system running efficiently year-round.
Most current mini-splits use R-410A refrigerant, which is being phased down by the EPA due to its high global warming potential. Newer systems are transitioning to R-32 or R-454B, both of which are more environmentally friendly. RJ's will ensure your new system uses compliant, future-ready refrigerants and meets all current and upcoming regulations.
Absolutely. Multi-zone mini-split systems can support up to 8 or more indoor air handlers from a single outdoor unit. They're ideal for whole-home use, especially in houses without ductwork or where zoned control is preferred. We'll help you design a layout that balances comfort and efficiency throughout your home.
Mini-splits are known for their quiet operation. Indoor units typically run at 19–30 decibels—quieter than a whisper. Outdoor units are also quieter than conventional AC condensers, making them ideal for homes in quiet neighborhoods or for use near bedrooms and living spaces.
No. Many homeowners use ductless systems to supplement their existing HVAC—such as adding cooling to an attic or garage, or solving hot/cold spots in specific rooms. You can keep your central system and install a mini-split where it makes the most impact.
Each indoor unit comes with a remote control, and many systems are compatible with Wi-Fi thermostats or smartphone apps. You can control temperature, fan speed, mode (heating/cooling), scheduling, and even energy monitoring—room by room.
Inverter technology allows the system to adjust compressor speed based on real-time temperature needs. Unlike traditional systems that cycle on/off at full power, inverter mini-splits ramp up or down as needed—saving energy, maintaining steadier temperatures, and extending equipment life.
Yes. Many high-efficiency ductless systems qualify for ComEd rebates, manufacturer incentives, and even federal tax credits under current energy efficiency programs. RJ's will help you navigate available savings and handle the paperwork.
Most single-zone installations take 1 day. Multi-zone systems may take 2–3 days, depending on the number of air handlers and the layout of your home. We handle everything from wall mounting and line sets to testing and walkthroughs.
Ductless systems are low-maintenance but should be serviced annually. Homeowners should clean filters monthly, and RJ's provides professional tune-ups that include coil cleaning, refrigerant checks, drainage inspection, and full system testing.
