FAQs
What is a ductless mini-split system and how does it work?
A ductless mini-split is a type of heat-pump HVAC system made up of one outdoor condenser and one or more small indoor air-handling units. Refrigerant lines, electrical wiring, and a condensate drain connect the indoor and outdoor components through a 3-inch wall penetration, eliminating the need for ductwork. In cooling mode the refrigerant absorbs heat from indoor air and releases it outdoors; in heating mode a reversing valve changes direction so the system pulls heat from the outside air—even in cold weather—and brings it indoors.
Are ductless mini-splits efficient for Petros’s climate?
Yes. Modern inverter-driven mini-splits reach SEER ratings in the upper 20s and HSPF ratings of 10 or higher, far exceeding the minimum federal efficiency standards. They modulate their output rather than cycling on and off, which saves energy and keeps temperatures consistent. Many models maintain 100 % heating capacity down to 5 °F and continue operating at ‑13 °F, making them suitable for Petros’s humid summers and occasionally frosty winters while cutting energy bills by 30-50 % compared with electric resistance heat or older central systems.
Can one system both heat and cool my home?
Absolutely. A mini-split is a reversible heat pump, meaning it delivers air-conditioning in summer and efficient heating in winter. Switching between modes is handled by an electronic reversing valve inside the outdoor unit; homeowners simply select “Heat” or “Cool” on the wireless remote or wall controller. Because the same equipment runs year-round, you avoid maintaining separate furnace and air-conditioning units.
How many indoor units will my Petros home need?
Sizing depends on square footage, insulation levels, ceiling height, window exposure, and how you use each space. A single-zone system heats and cools one area up to about 1,000 sq ft, while multi-zone condensers can support 2–8 indoor heads. During a free in-home assessment our technicians perform a Manual J load calculation to recommend the correct BTU capacity and the optimal placement for each head, ensuring balanced temperatures throughout your home without oversizing.
What does installation involve and how long does it take?
Because no ductwork is required, installation is faster and cleaner than a traditional central system. We mount the outdoor condenser on a pad or wall bracket, hang the indoor air handler high on an exterior or interior wall, run insulated refrigerant lines through a small core-drilled hole, connect wiring to a dedicated electrical circuit, evacuate and charge the system, then test operation. Most single-zone projects in Petros are completed in one day; larger multi-zone jobs typically take 1–2 days with minimal disruption.
How do costs and maintenance compare with conventional HVAC?
Up-front, a mini-split costs more than replacing a single window unit or electric furnace, but comparable to installing a new central heat pump with ductwork—and often less when you factor in duct sealing or replacement. Operating costs are markedly lower thanks to high efficiency and zone-by-zone control, and you may qualify for federal tax credits, TVA rebates, or local utility incentives. Maintenance is simple: clean or replace the washable filters every one to three months, keep the outdoor coil clear of debris, and schedule an annual tune-up. With no ducts, you eliminate energy losses from leaks and never need costly duct cleaning.
