MRCOOL 36k BTU 18 SEER Condenser — Model Details

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 BTU 18 SEER Condenser delivers 36,000 BTU of cooling and heating capacity, sized for spaces up to 1,500 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. SEER2 measures seasonal cooling efficiency — higher is better — and 18 meets modern federal minimum standards with headroom for utility rebates in most states. 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.

Cold & Hot Weather Operating Range

This system produces rated heating capacity down to 575.2°F ambient, best paired with a supplemental heat source in cold climates. On the cooling side the compressor runs down to 5122°F outdoor ambient, useful for server rooms, grow rooms, and any space that needs year-round cooling.

Power & Electrical Requirements

Power requirement: 208-230V 1-phase 60Hz (standard US residential 240V service). Minimum circuit ampacity is 24A with a maximum overcurrent protection of 40A. Wire the outdoor unit with 8 AWG copper on a dedicated 40A double-pole breaker (or single-pole at 120V), with a disconnect within sight of the condenser per NEC 440.14.

Install Difficulty — Professional Install

This is a professionally-installed condenser that requires a licensed HVAC technician with EPA 608 certification. The tech will pull a vacuum on the line set to 500 microns, pressure-test with nitrogen, release the factory charge, and commission per MrCool's startup procedure. Budget 1 full day for install on a single-zone system. Ships with R-410A refrigerant. R-410A is a mature, widely-serviced refrigerant; service technicians and parts are available at any HVAC supply house.

Frequently Asked Questions

Everything you need to know about this product

What size room will the MRCOOL 36k BTU 18 SEER Condenser cool?

At 36,000 BTU this unit is sized for rooms up to 1,500 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.

Do I need a licensed HVAC installer?

Yes — this unit is professionally-installed. The installer needs EPA 608 certification to handle R-410A, plus standard HVAC tools (vacuum pump, manifold gauges, nitrogen kit). Expect a one-day install on a single-zone system, more on multi-zone.

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.

How cold can it get outside before this heat pump stops heating?

Rated heating capacity holds down to 575.2°F. Below that temperature most units continue running but deliver reduced output. In climates with sustained single-digit overnight lows, pair with a backup heat strip or gas furnace.

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.

How fast does HVACZAR ship this unit?

Shipping is calculated at checkout from the order weight, and you see the exact charge before paying. In-stock SKUs leave the warehouse within 1–3 business days. Transit time is 3–7 business days via truck freight (with liftgate delivery) for outdoor units and UPS Ground for accessories. Tracking is emailed at pickup.

What if it arrives damaged or I change my mind?

Inspect the unit before signing for freight delivery. If there is visible damage, note it on the delivery receipt and refuse the shipment — we ship a replacement at no cost. Unopened and unused units can be returned within 30 days for a refund less outbound shipping.

What is the warranty on the MRCOOL 36k BTU 18 SEER Condenser?

The MRCOOL 36k BTU 18 SEER Condenser comes with a 10 years parts and labor manufacturer warranty when purchased from HVACZAR, an authorized MrCool dealer. Register your unit after purchase to activate full warranty coverage.

How long does shipping take?

Shipping is calculated at checkout from the order weight. Most MrCool systems ship within 1-3 business days and arrive in 3-7 business days via FedEx, UPS, or truck freight with liftgate delivery.

What size room does 36,000 BTU cover?

A 36,000 BTU unit is sized for rooms up to 1,500 sq ft. Proper sizing depends on ceiling height, insulation, climate zone, and window exposure. Use our system finder for a precise recommendation.

What is the efficiency rating?

This system is rated at 18 SEER2, meeting or exceeding Energy Star efficiency standards. Higher SEER2 ratings mean lower electric bills and better cooling efficiency.

Do you offer returns?

Yes. HVACZAR offers a 30-day return policy on unopened, unused products in original packaging. Contact us to initiate a return and receive a return authorization number.
