Landlord heat pump vs tenant bills: who pays for the box, who pays the kWh

A heat pump is one machine that heats and cools. The quote is still a capital invoice. The winter bill is a different invoice, and in a rental those two lines often have different names on them.

If you own the building and live somewhere else, you are looking at that split. If you rent and the landlord wants to swap the furnace, you are looking at the same split from the other chair. Neither of you should treat a $370 “average household savings” line as your unit.

This is a hire guide for the equipment and a reading guide for the lease. It is not tax advice and it is not a promise the electric bill will drop. Heat pump vs furnace is still the machine fork. Operating cost vs gas is the rate math. Stay here until you know who pays which meter.

The box is $15,393. The bill is whoever’s name is on it.

EnergySage’s 2026 marketplace average for an air-source heat pump is $15,393 before incentives. Ducted is $14,529. Hybrid (heat pump plus furnace) is $14,353. Whole-home ductless is $25,957. Those are mostly owner-occupied quotes. A small rental can be fewer tons. A 100-amp panel, leaky ducts, or a window-unit building with no ducts can push you the other way.

EnergySage: air-source heat pump costs (2026)

Their savings page cites Rewiring America for an average household saving of $370 a year after switching, with a range of about $60 to $840. That mix includes oil, propane, electric resistance, and gas. It is a crowd, not unit 2B.

NREL (now sometimes called out as the National Laboratory of the Rockies in that writeup) found a median $300 to $650 a year when people leave propane, oil, or resistance heat. Against natural gas, EnergySage is more careful: for a heat pump to beat gas, the price per kWh generally needs to be about 10% or less of the price per therm. Cheap gas plus pricey power is how an efficient box still raises the heating line.

If the landlord writes the $15,393 check and the tenant pays the kWh, those operating dollars never show up on the owner’s books unless the lease is written that way. That is the split. It is not a moral failing. It is two invoices.

Three meters, three jobs

The owner pays heat. Gas, electric, or both sit on the building account. A cheaper winter bill, if it actually happens, lands on the person who also paid for the machine. Comfort still matters for turnover, but at least the operating math and the capital math share a checkbook. Master-metered buildings live here.

The tenant pays electric, the owner paid gas. This is the messy swap. A furnace on the owner’s gas meter becomes a heat pump on the tenant’s electric meter. The owner may cut a gas bill they used to include in rent, or a gas bill they never saw. The tenant may see a new heating line they did not have. Do not call that “savings” until both meters are on the table for the same winter.

The tenant pays everything. The owner buys a machine to keep the unit rentable, to replace a dead AC, or because the city said so. Operating savings, if any, accrue to the occupant. The owner’s return is rent, vacancy, and not replacing a failed condenser in August. That can still be a good job. It is a different spreadsheet than a homeowner’s 10-year payback story.

None of those three is “the heat pump failed.” They are different deals. Write which one you have on the first page of the bid.

25C was never the landlord’s line

The IRS Energy Efficient Home Improvement Credit (25C) was for improvements to your main home, the place you live most of the year. Their own page says you cannot claim it if you are a landlord or other owner who does not live in the home. Even if you lived there, 25C does not apply to property placed in service after December 31, 2025. A 2026 rental install gets $0 from that federal line.

Federal 25C expired: what still pays in 2026

Take last year’s “$2,000 federal credit” off a 2026 quote. Utility and state programs sometimes allow rentals, sometimes they do not, and some are income-tested for the household in the unit. How to check your rebates is that call. Ask whether the account has to be residential owner-occupied. Do not let a salesperson subtract a homeowner rebate on a fourplex.

A tax person can talk about depreciation and repairs versus improvements. This page will not.

What the quote has to show besides SEER2

Same as any heat pump: a load calculation for this unit, not a rule of thumb from a detached house. Ducts or heads. Winter capacity. Panel amps. Weatherize if the attic is a sieve, because a bigger machine in a leaky rental just raises the tenant’s kWh.

Then add the rental lines:

Who holds each meter today, and who will hold them after the swap?

Does the lease include heat, and in which fuel?

Who programs the thermostat, and is there a lock or a schedule the tenant cannot fight?

Where does the outdoor unit sit relative to other units’ bedrooms? Heat pump noise is a neighbor issue in a duplex.

Who pays if the panel needs 200 amps? HomeGuide’s 100-to-200 band on the panel page is $1,300 to $1,600, or $1,800 to $2,500 if a new service panel is required.

A dead window shaker plus a gas furnace is two replacements. EnergySage’s ductless average is $25,957 for a whole house. One or two heads on a 600-square-foot apartment is not that number. Get the head count in writing.

What usually blows the rental number

Selling “you’ll save $370 a year” to an owner who never sees the electric bill. That average is not this unit, and it may not be this checkbook.

Moving heat from the owner’s gas meter onto the tenant’s electric without saying so in the lease. That is how you get a complaint in January, not a thank-you.

Subtracting 25C on a 2026 rental. Landlords did not get that credit when it lived. It is gone now anyway.

Skipping the panel because the old furnace was gas. The outdoor unit wants amps. The tenant’s microwave does not care whose name is on the HVAC invoice.

A thermostat the occupant cannot use. Setbacks that freeze pipes, or a locked 68°F that runs the strips. The machine is only as good as who holds the remote.

Guaranteed savings in the sales deck. EnergySage itself says a heat pump versus cheap gas often costs more to run. Put last winter’s rates on the table. If you cannot, you do not have a savings story.

What the driveway questions sound like

Whose name is on the electric meter, and whose name is on the gas meter, today?

After this install, which meter carries heat?

Is 25C or any homeowner rebate in this number for a 2026 finish? If yes, take it out.

What does the panel door say, and is a service upgrade in this bid?

How many indoor heads, or are we reusing ducts, and was there a load calc for this unit?

Who sets the thermostat, and what happens in a cold snap if the backup is electric strips?

How do I decide this week?

Name the meters before you name the brand. Owner-paid heat, tenant-paid electric, or a mix. The $15,393 average is the box. The bill is a separate line.

Do not count 25C. It was never for a rental you do not live in, and 2026 installs do not get it. Check the utility for rental-eligible rebates.

Run the rate math on operating cost vs gas if the same person pays both. If they do not, say so in the lease conversation instead of in a savings flyer.

Price the panel and the ducts as their own lines. A cheap outdoor unit on a 100-amp rental is how the change order shows up.

If you are the tenant, ask what fuel you will pay for in January, in writing, before the old furnace leaves. If you are the owner, ask whether this job is comfort and vacancy, or a bill you actually see. Write that answer on the first line of the quote.
