What this specific model is sized for, how it installs, how it performs, and what it costs to run.

Room & Space Coverage — 36,000 BTU

The MRCOOL® 36k DIY 5th Generation Bundle - includes Condenser, Air Handler, DIY® Quick Connect® Line Set, DIYPRO® Cable, and Remote - 230v delivers 36,000 BTU of cooling and heating capacity (3-ton class), sized for spaces up to 1,550 sq ft in standard 8-ft ceiling rooms with average insulation. At this capacity the unit is typically used for open-plan main floors, large garages, pole barns, finished basements, and small commercial bays. For homes with vaulted ceilings, heavy sun exposure, or poor insulation, plan on ~20% more BTU per square foot than the nominal coverage.

Efficiency & Operating Cost

This unit is rated at 18 SEER2 and 8.5 EER2 at full load. SEER2 measures seasonal cooling efficiency — higher is better — and 18 meets modern federal minimum standards with headroom for utility rebates in most states. For heating performance it carries a 8.5 HSPF2 rating, which translates to roughly 250–300% heating efficiency versus resistance electric — one kilowatt-hour of electricity moves three kWh of heat into the space at mild outdoor temperatures. Running the unit 8 hours a day at full load draws roughly 480 kWh/month — about $77/month at the US average $0.16/kWh residential rate. Real-world draw is usually 30–50% lower because inverter compressors modulate down most of the time.

Power & Electrical Requirements

Power requirement: 208/230V 1-phase 60Hz (standard US residential 240V service). Minimum circuit ampacity is 33A with a maximum overcurrent protection of 35A. Wire the outdoor unit with 8 AWG copper on a dedicated 35A double-pole breaker (or single-pole at 120V), with a disconnect within sight of the condenser per NEC 440.14.

Install Difficulty — DIY-Friendly

This DIY 5th gen Single-Zone Mini-split Bundle system ships with a pre-charged Quick Connect line set — no HVAC license, no vacuum pump, no refrigerant gauges. The pre-charged fittings use a hand-tightened mechanical seal that a homeowner completes in 15 minutes per connection. Typical install time from unboxing to first cool air is 4–8 hours for a single-head system. The system supports line set lengths up to 213.2ft; longer runs are available as accessory kits. Plan the shortest practical route — every 10ft of line set adds roughly 2% capacity loss. Ships with R-454B refrigerant. R-454B is the EPA 2025-compliant low-GWP replacement for R-410A, required for new-manufacture equipment — lower global-warming footprint without an efficiency penalty.

Sound Level & Comfort Features

Operating sound level ranges from 27.5 dB(A) on low to 55.5 dB(A) on high — the low end is whisper-quiet, below a normal conversation (60 dB) and comparable to a library reading room. The indoor blower offers 5 fan speeds plus auto mode, letting you trade airflow for quiet operation in bedrooms while running louder in living areas. Quiet mode caps fan speed and compressor rpm for an extra 2–3 dB drop in sound output.

Warranty & Certifications

Manufacturer warranty: 5 on parts, 7 on the compressor. AHRI certified and UL/ETL listed for North American electrical safety — required for most utility rebate and tax credit programs.

Frequently Asked Questions

Everything you need to know about this product

What size room will the MRCOOL® 36k DIY 5th Generation Bundle - includes Condenser, Air Handler, DIY® Quick Connect® Line Set, DIYPRO® Cable, and Remote - 230v cool?

At 36,000 BTU this unit is sized for rooms up to 1,550 sq ft under standard 8-ft ceilings with average insulation. Add 10–20% for sun-exposed rooms, poorly insulated spaces, or ceilings above 9 ft.

Can I install this myself without an HVAC license?

Yes — the DIY series uses pre-charged Quick Connect line sets that tighten by hand. No vacuum pump, no refrigerant handling, no EPA 608 certification required. Most single-zone installs take 4–8 hours. You may still need a permit and an electrician for the 240V circuit, depending on local code.

Is this unit eligible for the federal 25C tax credit?

At 18 SEER2 this unit meets the efficiency thresholds most ENERGY STAR cold-climate heat pump programs require, which is the trigger for the 25C credit (up to 30% / $2,000 in 2026). Confirm with your tax advisor and save the AHRI certificate from your order confirmation.

What electrical circuit do I need for installation?

208/230V dedicated circuit with the disconnect within sight of the outdoor unit per NEC 440.14. An electrician will size the breaker based on the minimum circuit ampacity shown on the nameplate. Budget $400–$900 for a new dedicated 240V circuit if one isn't already present.
