• Long-term maintenance costs

This guide compares mini splits vs. central air systems on real-world factors — and shows you why Mark chose a MRCOOL DIY 5th Gen 36k 3-Zone Mini Split System over replacing his aging ducted setup.

🌬️ Airflow & Comfort: One Thermostat vs. Three Zones

Central HVAC:

• One thermostat controls entire home

• Uneven temperatures (especially upstairs)

• Energy wasted on unused rooms

MRCOOL Mini Split:

• Each air handler (9k and 12k) is independently controlled

• Customize bedroom, living room, and office temps

• Turn off zones when not in use

🧠 Mark keeps the guest bedroom at 78°F when unoccupied, his office at 72°F during work hours, and the living room at 74°F.

🌡️ Energy Efficiency: Zoned Savings Add Up

💡 Mini splits shine in both summer and winter — especially if you live in a moderate or mixed climate like Virginia, North Carolina, or Northern California.

🔧 Installation: DIY vs. Ducted Construction

Central Air:

• Requires ductwork in walls/ceilings

• Often tears into drywall

• Needs attic or crawlspace access

• 2–5 day install with HVAC crew

MRCOOL DIY:

• Each indoor unit needs only a 3.5” hole

• Line sets are pre-charged (no vacuum pump needed)

• Quick Connect system with flare fittings

• Complete install takes 1–2 days for a capable DIYer

🧼 Maintenance: Simple vs. Systemic

Central Air:

• Annual tune-ups

• Duct cleaning every 3–5 years

• Filter replacement

• Risk of duct mold or rodent intrusion

Mini Split:

• Monthly filter rinse

• Coil and drain cleaning each season

• No ducts = no duct-related issues

• Remote and app control updates

💡 With Mark’s MRCOOL setup, he spends just 10–15 minutes per unit each month for maintenance.

🧱 Retrofit & Remodel Friendly

Mini splits are ideal for:

• Homes without existing ductwork

• Older homes or row homes

• Additions and garages

• Upstairs zones that are too warm

• Downstairs basements that stay cold

Mark’s 1970s home had no ductwork upstairs — instead of running new lines, he placed a 12k head in the upstairs hallway and a 9k head in the office. No ceiling damage, no attic work.

💬 Why Mark Chose MRCOOL Over Central Air

“I was quoted $12,400 to replace my failing central system. That didn’t include tearing up drywall or replacing old ductwork. I researched mini splits and realized the MRCOOL DIY system could give me the same (or better) comfort — for less than half the cost — and I could install it myself. Two years later, I have no regrets.”
