FAQs
How do ductless mini-split systems provide heating and cooling?
A ductless mini-split has two main parts: an outdoor compressor/condensing unit and one or more indoor air-handling units (often called "heads"). Refrigerant lines, a condensate drain, and a small power cable connect the components through a three-inch wall penetration. In cooling mode, refrigerant absorbs heat from indoor air and rejects it outdoors; in heating mode (via a heat-pump cycle) it reverses direction and brings warmth inside. Because each indoor head has its own fan and thermostat, you get zoned temperature control without ductwork losses.
Are ductless mini-splits efficient enough for Maryville’s hot summers and cool winters?
Yes. Modern mini-splits routinely achieve SEER ratings of 20–30 for cooling and HSPF ratings of 10–13 for heating—far above the federal minimums. Maryville’s climate (humid summers with average highs in the 80s and mild to moderate winters) is ideal for heat-pump technology. Variable-speed inverters allow the system to modulate output, so it runs longer at low power instead of cycling on and off, saving energy and keeping humidity in check during peak July and August conditions.
Can a ductless system condition my whole house or just one room?
Both options are possible. A single-zone mini-split is perfect for bonus rooms, garages, additions, or any space lacking ductwork. For whole-home comfort, a multi-zone system can connect 2–8 indoor heads to one outdoor unit, giving each major area its own thermostat. Our Maryville HVAC team performs a load calculation to size the equipment, recommends head locations for balanced airflow, and confirms your electrical panel can handle the additional load.
What does installation involve and how long does it take?
Most single-zone installations take one day; multi-zone projects usually wrap up in two. We mount the outdoor unit on a pad or bracket, drill a small aperture for line-sets, hang the indoor head(s), pull vacuum on the refrigerant lines, pressure-test for leaks, and commission the system. The City of Maryville and Blount County require mechanical permits, which we secure and close out with an inspection. Because no bulky ductwork is added, the job causes minimal disruption to walls and ceilings.
How much do ductless mini-splits cost and are there incentives?
In Maryville, a professionally installed single-zone system generally ranges from $3,500–$6,000. Multi-zone packages vary from $7,000 to $15,000+, depending on capacity, number of heads, and finish options. TVA’s EnergyRight program and federal tax credits under the Inflation Reduction Act can reduce net cost by 10–30%. We also offer 0% or low-interest financing plans with approved credit, letting you spread payments over 12–60 months.
What maintenance do mini-splits need and can you service them?
Compared with ducted units, upkeep is straightforward. Homeowners should rinse or vacuum the washable air filters every 4–6 weeks and keep outdoor coils free of leaves or grass clippings. Once a year, schedule our Precision Tune-Up: we deep-clean the indoor coil, flush the condensate line, check refrigerant pressure, inspect electrical components, and verify thermostat calibration. Proper maintenance preserves warranty coverage and typically restores 10–15% lost efficiency.
