FAQs
What exactly is a ductless mini-split and how does it heat and cool my Grandview home?
A ductless mini-split is a small, two-part HVAC system consisting of an outdoor condenser/heat-pump unit and one or more indoor air-handling units (called "heads"). The two sections are connected only by a narrow refrigerant line set and low-voltage wiring that pass through a 2–3" wall opening, so no bulky air ducts are needed. In cooling mode, the outdoor unit absorbs heat from your indoor air and expels it outside; in heating mode, the refrigeration cycle reverses, pulling warmth out of outdoor air—even when it’s below freezing—and delivering that heat into your living space. Because each indoor head has its own fan and thermostat, you get room-by-room temperature control and very quiet operation.
How well do mini-splits perform in Grandview’s hot summers and chilly winters?
Modern inverter-driven mini-splits are designed to handle a wide outdoor temperature range. On the cooling side, they maintain full capacity up to about 115 °F, which covers the hottest Grandview afternoons. For heating, most "hyper-heat" models continue supplying 80–100 % of their rated capacity down to 5 °F, and will still produce usable heat below 0 °F—well below our typical winter lows. Their variable-speed compressors automatically ramp up or down to meet real-time load, so you avoid the temperature swings common with traditional single-stage furnaces and central air conditioners.
Can one outdoor unit serve multiple rooms or zones?
Yes. A single multi-zone condenser can connect to as many as eight indoor heads, depending on the model and total capacity. This flexibility lets you condition the whole house or just the rooms that need it—bonus rooms, finished basements, new additions, converted garages, etc. Each head has its own remote or wall controller, so family members can set individual comfort levels while the system modulates overall output for maximum efficiency.
What is involved in installing a ductless system in an existing Grandview home?
Because no ductwork is required, installation is fast and minimally invasive. Our technicians start by helping you choose head locations that provide good airflow and aesthetics. We mount the indoor units high on an exterior or interior wall, install the outdoor condenser on a pad or wall bracket, and run the refrigerant/condensate line set through a small sleeve. Typical one-zone projects take about a day; multi-zone installs may take two to three days. You won’t need major drywall repairs, attic work, or big changes to your electrical panel—most systems draw 15-25 amps on a dedicated 240-V circuit.
How much does it cost to operate a mini-split compared with a conventional HVAC system?
Ductless heat pumps typically achieve SEER ratings of 20–30 for cooling and HSPF ratings of 10–13 for heating. By comparison, many older central air conditioners operate at 10–14 SEER, and gas furnaces are often 80 % efficient. In real-world Grandview energy-rate studies, homeowners switching to mini-splits commonly see 25–50 % savings on summer electric bills and 30–60 % on winter heating costs (versus electric resistance or older heat pumps). You also eliminate the 20–30 % duct losses found in attic or crawl-space ductwork, which further lowers monthly expenses.
Do ductless systems require maintenance, and what services do you provide?
Like any HVAC equipment, mini-splits perform best with routine care. Homeowners should rinse or vacuum the washable air filters every 4–6 weeks. Once a year our Grandview service team will: inspect refrigerant pressures, clean indoor and outdoor coils, flush the condensate drain, test compressor amp-draw, check electrical connections, update firmware (if applicable), and verify thermostat calibration. Regular maintenance extends equipment life, preserves factory warranties, and keeps efficiency ratings where they belong.
