A used split on a listing site costs a fraction of the price of a new one; once a certified technician has taken it down, another has put it up with new pipes and gas, and the older machine has drawn more electricity for five summers, it can cost more than new. A rental with maintenance included looks painless until the total is added up. This kit does that arithmetic with your own quotes, and puts the checks and the contract terms on paper before you pay.

Every rule names its text and was checked on EUR-Lex on November 7, 2026: Directive (EU) 2019/771 and its amendment by Directive (EU) 2024/1799, Directive 2011/83/EU, Regulation (EU) 2024/573, Directive (EU) 2023/2225 and Directive 2012/19/EU. Electricity prices are Eurostat’s (nrg_pc_204, second half of 2025); machine prices, rents and hire rates in the worked examples are labelled as example inputs, never as market rates.

What you get

• The five-year arithmetic: new, used, refurbished, long-term rental and lease with purchase option compared line by line with a worked example at the Spanish electricity price, and the cases where the arithmetic is not the answer.
• The guarantee on used goods: four kinds of seller, what Directive (EU) 2019/771 gives you from a dealer (two years, or at least one year for used goods where your country allows it), the extra 12 months after a repair, the 14-day withdrawal online, and what is left with a private seller.
• The F-gas rules when a split changes hands: who may remove and refit it, why the bans on new equipment do not touch a used unit, the refrigerant table (R-22 is a walk-away), and taking back the old unit.
• The 25-point inspection: papers, the units at rest, a 20-minute running test and the deal, each point with how to check it and when to walk away; the points that apply to a portable are marked.
• Pricing a used unit: the maximum price formula, a worked example, what changes the result, and the receipt for a private sale.
• Short-term hire for an event, an office or a site: what is hired, what to tell the hire company for sizing, the quote line by line, and the hire-or-buy break-even in weeks.
• Long-term rental and leasing: three contracts that look alike, the consumer credit rules that apply from November 20, 2026 to a lease with a purchase option, the rental calculator and how to find the interest rate hidden in a lease.
• The contract checklist (deposit, maintenance, removal, insurance, buy-back, end of contract), five warning signs, a delivery record, and three messages ready to send.

Who it is for

• Households who have found a used split, portable or monobloc on a listing site, or a refurbished one from a dealer, and want to know what to check, what it will really cost once installed and what rights they have if it fails
• Tenants, landlords and owners hesitating between buying new, buying used and renting an air conditioner for a few summers
• Businesses, event organisers, offices and site managers who need cooling for days, weeks or a season and want to compare short-term hire, long-term rental, leasing and buying

Introduction

A second-hand air conditioner looks like the cheap way to get through a heatwave, and hiring one looks like the flexible way. Sometimes they are. Often the saving disappears in the lines nobody puts in the listing: the certified technician who must remove a split and the one who must refit it, the new pipes, the recharge, the extra electricity of an older machine, a rental that never ends, or a hire contract that charges for delivery, collection and damage on top of the weekly rate.

This kit puts those lines on paper before you pay. It starts with the arithmetic: new, used, refurbished, long-term rental and leasing compared over five years with your own figures, then short-term hire against buying for a few weeks a year. It then sets out what the law gives you on a used machine (the EU sale of goods directive, which treats a dealer and a private seller very differently), what the F-gas regulation requires when a split is taken down and put up again, and a 25-point inspection you can run in half an hour at the seller's home. The last chapters cover hire and rental contracts, leasing, and what to put in writing, with three messages ready to send.

How to use it: chapter 1 tells you which route is worth pursuing for your case. If you are buying used or refurbished, read chapters 2 to 5 in order, and take the inspection grid of chapter 4 with you (it is also a spreadsheet on your access page). If you are hiring for a short period, go to chapter 6; for a rental or lease of a year or more, chapters 7 and 8. Chapter 9 has the three templates. Print it (Ctrl+P or Cmd+P, then "Save as PDF", or print on paper). The five-year cost comparison and the inspection grid are also on your access page as spreadsheets.

The texts were checked on November 7, 2026 on EUR-Lex: Directive (EU) 2019/771 on the sale of goods, as amended by Directive (EU) 2024/1799 on repair, Directive 2011/83/EU on consumer rights, Regulation (EU) 2024/573 on fluorinated gases, Directive (EU) 2023/2225 on consumer credit and Directive 2012/19/EU on waste electrical equipment. Electricity prices are Eurostat's household prices for the second half of 2025 (dataset nrg_pc_204). Every calculation is shown; the prices of machines, installations, rents and hire rates in the worked examples are example inputs, never market rates: replace them with the quotes you receive.

Chapter 1: New, used, refurbished, rented or leased: the five-year arithmetic

The price on a listing is one line out of six. Before comparing machines, compare routes: what each one costs you over the years you will actually use it, all lines included.

The six lines that decide it

1. What you pay at the start: the machine, its removal at the seller's (used split), the installation, any repair or recharge needed before use, a rental installation fee.
2. What you pay every month: the rent or the lease payment, for as many months as the contract runs.
3. What you pay at the end: a purchase option on a lease, the removal of a rented unit, making good the wall.
4. Electricity: the same room needs the same amount of cooling whatever the machine; an older or less efficient unit simply draws more electricity to deliver it.
5. Servicing: included in most rentals, paid by you otherwise.
6. Repairs: covered by the guarantee for a while, then yours; on a used machine, sooner.

The method, line by line

Electricity a year = cooling needed in a year (kWh) ÷ SEER of the machine × your price per kWh.

• Cooling needed in a year: the capacity of the room's machine in kW × the hours it runs at that output in a season. A 2.5 kW room run the equivalent of 500 hours needs about 1,250 kWh of cooling. Use the same figure for every route: it is the room that decides it, not the machine.
• SEER: the seasonal energy efficiency ratio on the EU energy label or the datasheet of the model (Regulation (EU) No 626/2011). For a used unit, look it up from the model number on the nameplate (chapter 4). For a portable, use the EER on its label.
• Your price per kWh: the unit rate on your bill, all taxes included. Eurostat's household averages for the second half of 2025 (band 2,500 to 4,999 kWh a year, all taxes) range from €0.1082 in Hungary to €0.4042 in Ireland; Germany €0.3869, Italy €0.2966, Spain €0.2669, France €0.2561, the Netherlands €0.2551, Greece €0.2381, Portugal €0.2435. Your own contract is the figure to use.

Total over five years = start + monthly payments × months + end + 5 × (electricity + service + repair reserve).

A worked example

A 2.5 kW living room in Spain, 1,250 kWh of cooling a year, electricity at €0.2669 per kWh. The prices below are example inputs chosen to show the method, not market rates.

The workings: new, 1,800 + 5 × (48 + 90) = 2,490. Used, 1,500 + 5 × (83 + 90 + 150) = 3,115. Refurbished, 1,600 + 5 × (61 + 90 + 50) = 2,605. Rental, 2,950 + 5 × 55 = 3,225. Lease, 2,210 + 5 × (48 + 90) = 2,900. Electricity: 1,250 ÷ 7.0 = 178.6 kWh × 0.2669 = €47.66, rounded to €48; 1,250 ÷ 4.0 = 312.5 kWh, €83.41; 1,250 ÷ 5.5 = 227.3 kWh, €60.66; 1,250 ÷ 6.1 = 204.9 kWh, €54.69.

What the example shows, and what it does not. With these inputs the used split is the dearest owned route, because the machine is the only line it saves: the removal, the full installation and the risk of a recharge remain, and the older machine draws more electricity every year. Change one input and the order can change: a used split bought with its installation already paid (it stays on the wall of the house you buy), a heavily used room where the electricity line grows, a rental used for two summers instead of five. That is why the spreadsheet exists. Enter your own quotes, your own price per kWh and the SEER of the actual models.

When a route wins on its own terms

• Used or refurbished portable or monobloc: no installation, no refrigerant work, a test in five minutes. The cheapest honest second-hand purchase, if the room suits a portable.
• Refurbished split from a dealer: a legal guarantee of at least one year, an invoice, a machine checked by someone accountable (chapter 2). Worth it when the price gap with new is larger than the gap in efficiency over your years of use.
• Used split, private seller: worth it only when the machine is recent (R-32), seen running, removed properly by a certified technician, and priced as chapter 5 shows.
• Short-term hire: a few days or weeks a year, an event, an office during works, a site (chapter 6).
• Long-term rental: a few summers in a place you will leave, when you value maintenance included and nothing to sell at the end more than the total.
• Leasing: a business that prefers monthly payments to capital, or a household that wants new equipment without the cash, when the contract shows its total cost and its interest rate (chapter 7).

The three cases where the arithmetic is not the answer

• The building or the landlord will not allow a split. The route is decided for you: a portable or a monobloc, bought or hired. Get the written consent question settled first; it changes everything after it.
• You need it this week. A used portable or a hired unit can be cool tonight; a split installation can take weeks in a heatwave.
• You cannot afford the risk. A used machine without a guarantee can fail in its first summer; if a €900 surprise would be a problem, the guarantee of a dealer, a new machine or a rental is worth its premium.

Frequently asked questions

How do I receive the guide?

Right after payment you are taken to your guide page, with the spreadsheet to download. Bookmark it: the link stays valid and always shows the latest version. To keep a PDF, save it from your browser (Ctrl+P or Cmd+P, then "Save as PDF"): the layout is made for printing. Stripe emails you the receipt, and "Find my purchases" at the bottom of every page sends the link again.

Is VAT included? Is it a subscription?

€29 is the total you pay, VAT included, once. There is no subscription and nothing is charged later. Your card details go to Stripe and never reach us.

Does it tell me what a used air conditioner is worth?

Not as a market price, which nobody can honestly give for your city and your model. It gives you the formula and a worked example: the price of an equivalent new unit installed, minus everything the used route still costs (removal, installation, recharge, extra electricity, the missing guarantee). With two quotes from your installer, you have your own maximum price in ten minutes.

I only want a used portable. Is it worth it?

Partly. The F-gas chapter and the removal steps do not apply to a sealed portable, but the guarantee chapter, the inspection points marked for portables, the hire-or-buy break-even and the five-year comparison do. If you just need a portable for a few weeks, chapter 6 tells you whether hiring or buying it is cheaper.

Does it apply in my country?

The rules it explains come from EU texts that apply in every member state: the sale of goods directive, the consumer rights directive, the F-gas regulation, the consumer credit directive. Where a directive lets countries choose (the shorter guarantee for used goods, for example), the kit says so and tells you what to ask. UK readers can use the method, the inspection and the contract checklist; the guarantee chapter follows EU law.

Is it legal or financial advice?

No. It quotes the texts and shows how they apply to common situations. For a dispute, contact your national consumer authority or the European Consumer Centre of your country; for the accounting of a business lease, your accountant.

What is the guarantee?

The guide is guaranteed as described: if it does not open or contains an error, we fix it, and if we cannot, we refund you in full (refund policy in the terms of sale). Write to admin@tech-bharat.com. A duplicate payment is always refunded.
