What you need to know

Line sets must match your mini-split's connection sizes. 1/4" × 3/8" is the most common size for 9,000–18,000 BTU single-zone systems. For larger BTU units or multi-zone setups, you may need a different size — call us if you're unsure.

Installation

Refrigerant line work must be performed by a licensed HVAC contractor who can pull a vacuum, check for leaks, and properly charge the system.

Saved $2,400 vs local contractor

Got quoted $9,200 from a local HVAC contractor for a furnace replacement. Found Furnace Direct and got the exact same Goodman unit for under $5k delivered. My installer couldn't believe the price and installed it in one day. Runs perfectly.

Fast shipping, exactly as described

Ordered on a Tuesday, pallet arrived Friday. Unit was packed well, no damage, all factory sealed. Andrew answered my sizing question over the phone and got me the right model. Couldn't be happier with the purchase.

Installer said same one he'd buy at supply house

My HVAC guy said he pays basically the same price at his wholesale supply house. The markup contractors add is insane. Furnace Direct cut the middleman out entirely. Will recommend to everyone I know.

Heating my 2,200 sq ft home perfectly

Installed my 96% AFUE furnace a couple months ago. Heats my 2,200 sq ft home perfectly, and my gas bill dropped noticeably compared to the old unit. Great product, great price, great experience from start to finish.

Saved enough to pay for the install

Math was simple: 3 contractor quotes all over $8k. Furnace Direct plus local installer was under $5,500 total. Saved enough to basically pay for the install myself. Quality is identical to what contractors charge a fortune for.

No-pressure, honest pricing

Called a few HVAC companies first — every single one wanted to schedule an "in-home consultation" before giving me a price. Furnace Direct just showed me the price. Bought online, shipped next day, done. This is how it should work.

Common Questions About This Mini-Split Systems

How much does installation cost?

Mini-split installs range from $1,500 (single-zone, simple wall-mount) to $4,500+ (multi-zone, ceiling cassette, longer line sets). We schedule install with a licensed installer in your area after order. Equipment ships fast — install date is set during checkout follow-up.

How do I know if this will fit my home?

Mini-split BTU sizing rule of thumb: 9,000 BTU cools ~350 sqft, 12,000 BTU cools ~550 sqft, 18,000 BTU cools ~750–1,000 sqft, 24,000 BTU cools ~1,200 sqft, 36,000 BTU cools ~1,500–1,800 sqft. Insulation and sun exposure shift the math. We confirm sizing free if you give us room dimensions before you order.

What is the warranty?

All equipment ships with the full manufacturer warranty (typically 10 years parts, 1 year labor on the compressor/heat exchanger). Registration is required — we send registration instructions with the unit. Install through our licensed installer network preserves the warranty; DIY install may void coverage depending on the manufacturer.

How fast does this ship?

In-stock equipment ships within 1–2 business days via freight (pallet delivery). Transit is typically 3–7 business days depending on your zip. You will receive a tracking number and the freight carrier will call to schedule curbside delivery. Equipment is in stock unless the product page shows "Special Order".

Is financing available?

Yes. Shop Pay and Affirm offer 0–36% APR financing at checkout with options from 3 to 48 months — most homeowners qualify for $150–$250/mo payments on a full system. For installs we work with Wisetack home-services financing (no impact to credit to check rates). Apply at checkout and a decision takes under a minute.

Do you handle the install permit?

Mini-split installs typically do not require a permit if the existing electrical disconnect is reused. If a new disconnect or breaker is needed your installer will pull a permit. Permit handling is included in install cost when required.

Can I install this myself?

Some mini-splits ship with quick-connect line sets that DIY-capable homeowners can install (e.g., DIY-series with pre-charged line sets). Most professional installs are still recommended because vacuum-pulling a refrigerant line and verifying torque on flare connections requires HVAC tools. Reach out if you are unsure whether this model is DIY-friendly.
