FAQs
What is a ductless mini-split system and how does it differ from traditional central air conditioning?
A ductless mini-split combines an outdoor compressor with one or more indoor air-handling units. Instead of using ductwork to move conditioned air, each indoor unit delivers heating or cooling directly into the room. This eliminates energy losses that occur in ducts, allows independent temperature control for each zone, and simplifies installation—ideal for Rockwood homes without existing ductwork, older properties, or new room additions.
Will a mini-split provide enough heating and cooling for Rockwood’s four-season climate?
Yes. Modern cold-climate mini-splits are engineered to operate efficiently in temperatures as low as ‑15 °F, which comfortably covers Rockwood’s winter lows. In summer, variable-speed inverters modulate output to maintain steady indoor comfort even during heat waves. Correct system sizing and professional installation ensure you have enough capacity to handle both extremes.
How energy-efficient are ductless mini-splits compared with window units or baseboard heaters?
Mini-splits typically achieve Seasonal Energy Efficiency Ratios (SEER) of 20–30 and Heating Seasonal Performance Factors (HSPF) of 10–13, far exceeding the efficiency of most window A/Cs (SEER 10–13) and electric baseboard heaters (which are 100 % efficient at the point of use but costly to run). Because they use variable-speed compressors and avoid duct losses, homeowners in Rockwood commonly see energy savings of 25–40 % over conventional systems.
What is involved in installing a ductless mini-split in my Rockwood home?
A typical single-zone install takes one day. A 3-inch hole is drilled through the exterior wall for the refrigerant lines, power cable, and condensate drain. The outdoor condenser is mounted on a pad or wall bracket, and the indoor air handler is hung high on an interior wall or mounted as a floor unit. Multi-zone systems repeat this process for each indoor head. Because no ducts are required, there is minimal disruption to finished walls or ceilings.
How much maintenance do ductless systems require?
Routine maintenance is simple: rinse or vacuum the washable air filters every 4–6 weeks, keep the outdoor unit free of debris and snow, and schedule a professional tune-up once a year to check refrigerant pressure, electrical connections, and coil cleanliness. Following these steps helps maintain high efficiency, quiet operation, and manufacturer warranty coverage.
Are there rebates or incentives available in Rockwood for installing a ductless mini-split?
Yes. Many Rockwood homeowners qualify for provincial or utility rebates that can offset $500–$2,000 of the installation cost when replacing electric resistance heat or upgrading to ENERGY STAR-rated equipment. In addition, the federal Greener Homes Grant and low-interest financing may apply. We’ll guide you through the paperwork to ensure you receive every available incentive.
