Ductless Mini-Split in Grandville, MI

Not every room in your Grandville home connects to ductwork, and not every heating or cooling problem requires a whole-house system. That's where ductless mini-splits come in. We install mini-split systems across Grandville for homeowners who need climate control in a finished garage, a bedroom addition, a sunroom, or an older home that was built without ductwork. Mazure's has been doing HVAC work in the Grandville area since 1987, and ductless systems have become one of the fastest-growing parts of our business. Our Jenison shop is 10 minutes from your door.

We regularly serve homes in Downtown Grandville, Ivanrest — near RiverTown Crossings Mall and Grandville Avenue. Our Jenison headquarters puts us just 10 minutes from our Jenison shop, which means convenient scheduling for appointments and installations.

Grandville's housing stock creates plenty of situations where ductless is the right call. The post-war ranches near Downtown Grandville sometimes have additions — a back bedroom, a family room bump-out — that the original ductwork doesn't reach. Running new ductwork to these spaces can cost more than the mini-split itself and requires cutting into finished walls and ceilings. A ductless unit solves the problem with a small hole in the wall for the refrigerant line, no major construction required. Finished garages are another common project. Grandville homeowners who use their garage as a workshop, home gym, or hobby space need heating and cooling out there. A ductless unit provides both in a single system, and it heats efficiently even when outdoor temps drop below zero. Above-garage bonus rooms are notorious for being hot in summer and cold in winter because they're poorly insulated and far from the main HVAC system. A ductless unit gives that room its own independent temperature control. We also install ductless systems in older Grandville homes that have hot water radiator heat and no ductwork at all. Instead of retrofitting the entire house with ductwork for central air, a multi-zone ductless system can cool and heat the whole home room by room.

We install ductless mini-splits from Mitsubishi, Fujitsu, and Carrier. Mitsubishi's Hyper-Heating line is our go-to for cold-climate applications — it maintains full heating capacity down to -13°F, which handles the worst Grandville winters without backup heat. Fujitsu and Carrier offer competitive options in the same performance range. A single-zone system — one outdoor unit connected to one indoor unit — covers one room or area. This is the most common setup for a garage, addition, or bonus room. Single-zone systems typically cost between $3,500 and $5,500 installed, depending on the size and brand. Multi-zone systems connect one outdoor unit to two, three, or even five indoor units throughout the home. Each zone has its own thermostat, so you heat and cool only the rooms you're using. A two-zone system runs $6,000 to $9,000, while a whole-home multi-zone system for a Grandville house without ductwork can range from $10,000 to $15,000. We size every system using a room-by-room load calculation. An oversized mini-split short-cycles, wastes energy, and doesn't dehumidify well. An undersized unit can't keep up on extreme days. Getting the size right matters, and we have the experience to do it accurately.

A single-zone ductless installation in Grandville typically takes four to six hours. We mount the indoor unit on the wall (or ceiling, depending on the model and your preference), drill a three-inch hole through the exterior wall for the refrigerant line and condensate drain, and set the outdoor unit on a mounting pad or bracket outside. The refrigerant lines are connected, the system is charged, and we run it through heating and cooling cycles to verify performance. For multi-zone installations, plan on one to two days depending on how many indoor units are being installed and where they're located. We run refrigerant lines through walls, attics, or crawl spaces to keep them hidden. The outdoor unit is larger than a single-zone condenser but still compact — about the size of a standard AC condenser. Every ductless system we install includes a wireless remote control for each zone, and most models also work with a wall-mounted thermostat or smartphone app. We walk you through the controls before we leave and make sure every zone is heating and cooling to your satisfaction.
