Ductless Specialists for Rochester's Older Homes

Ductless Mini-Split Installation & Repair in Rochester, NY

Much of Rochester’s housing was built before central air conditioning became standard, and many of these homes are heated by radiators or baseboard systems with no existing ductwork. Installing new ducts can be costly and disruptive. A ductless mini-split system provides an efficient alternative, delivering zoned heating and cooling through a compact outdoor unit, a small refrigerant line and discreet indoor units.

Ductless systems are particularly effective in spaces that are difficult to condition in older homes, such as third-floor bedrooms, enclosed porches, finished attics and additions.

Rochester HVAC FAQ

The cost depends on the size of the home, the efficiency rating selected and any required venting changes. Upgrading from an older chimney-vented furnace to a 95%-efficient model typically requires new PVC venting, which is common in older Rochester homes. We provide a free written proposal for every installation, so you know the full cost before any work begins.

Modern cold-climate heat pumps continue heating efficiently at temperatures well below freezing. Pairing a heat pump with an existing furnace or boiler allows it to handle most of the heating season, with the existing system providing backup during the coldest periods. RG&E Clean Heat incentives can reduce the installation cost, and we will confirm which programs apply to your home.

The $5,000 rule is a general guideline: multiply the age of the system by the cost of the repair. If the result exceeds $5,000, replacement is often the better investment. For example, a 15-year-old air conditioner needing a $400 repair produces a figure of $6,000. We also consider efficiency, refrigerant type and overall system condition before making a recommendation.

Ductless mini-split systems are designed for homes without ductwork and require only a small opening for the refrigerant line. Most models also provide heating, supplementing radiator systems during winter. Homes with existing forced-air ductwork can add central air conditioning instead.

Emergency service is available 24 hours a day, seven days a week, including holidays, throughout the City of Rochester. Call 585-425-8116.
