What is the SEER2 rating of the Lennox VPC036H4M-3PS?

The Lennox VPC036H4M-3PS is rated at up to 18.4 SEER2 and 11.7 EER2 for cooling and up to 9.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the Lennox VPC036H4M-3PS good for cold climates?

It is not cold-climate certified: none of its matchups meet the ENERGY STAR cold-climate criteria (a COP of at least 1.75 at 5°F among other limits). In places with frequent sub-zero nights, pick a cold-climate 36,000 BTU model.

How much does the Lennox VPC036H4M-3PS cost to run per year?

At its rated efficiency it costs about $924-$2,740 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,176 in Phoenix and $2,318 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the Lennox VPC036H4M-3PS the same as the Midea MDV-V36WMN1T?

Yes, as far as the certified ratings go. ENERGY STAR lists both model numbers with identical efficiency, capacity and matchups, which means the same outdoor unit sold under a different brand or with a minor variant code (voltage, colour or region). The full list is on this page.

What refrigerant does the Lennox VPC036H4M-3PS use?

It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and R-32.

36,000 BTU mini-split heat pump · Lennox Real

Lennox VPC036H4M-3PS

Below average cooling and heating efficiency for a 36,000 BTU mini-split heat pump, but not rated for cold climates.

Ranks #194 of 205 36,000 BTU mini-splits for cooling efficiency, and costs about $1,120 a year to run in a mixed climate like Atlanta.

A good fit if…

You want steady temperatures and quiet running - the compressor varies its speed.

Think twice if…

You often see nights below 0°F - it is not cold-climate certified.
Cooling cost matters most - its SEER2 is below average for mini-splits.
You mainly need heat - its HSPF2 is below average for mini-splits.
You want the newest refrigerant - it uses R-410A, which is being phased down.
