HVAC Repair — Ireland

HVAC Warranty Costs (Ireland, 2026)

In the Republic of Ireland there is no single manufacturer-warranty norm — the term depends heavily on the fuel. Gas boilers commonly carry 7- to 10-year guarantees, while oil boilers — the mainstay of the off-mains-gas housing stock — often get only 1 to 2 years on the appliance itself. Whatever the length, cover is conditional: registering the appliance within about a month and servicing it every year are the homeowner's job, and the qualifying installer credential differs by technology — RGII for gas, OFTEC for oil, and F-Gas certification for heat pumps and air conditioning. A manufacturer guarantee is also separate from the homeowner's statutory rights against the seller under the Consumer Rights Act 2022. Below: every brand's terms with its own source, and what actually voids cover. Informational only — no rankings, no recommendations. Reviewed July 2026.

Manufacturer warranty terms, by brand Estimated

Standard = the base defect warranty; component = any longer coverage on specific parts. Each row cites that brand's own official warranty documentation (retrieved 2026-07-19). Terms vary by model and change over time — confirm on the manufacturer's current warranty document.

Brand	Standard warranty	Extended component coverage	Source
Grant	Irish-headquartered (Birr, Co. Offaly) oil-boiler manufacturer. The Grant Vortex oil boiler product page markets a "5 Year guarantee" but the footnote defines it precisely: "One year manufacturer's warranty with five year guarantee on boiler heat exchanger (T&Cs Apply)." Read plainly, that is ONE year of whole-appliance cover with the longer five-year term attaching only to the heat exchanger — not five years on the boiler.	Aerona³ air source heat pumps — Grant's published FAQ is internally self-contradictory on the length, so NO combined or extended figure is asserted here. It states both "Grant Aerona³ air source heat pumps are guaranteed for 5 years from the date of installation" and, separately, "The guarantee period will be a total of three years (excluding consumable items) if the product is registered within 30 days from installation, subject to being serviced annually" — a 5-year headline against a registration clause worded as "a total of three years", NOT "a further three years", so any reading of an 8-year term is unsupported and is not made here. What is unambiguous: registration within 30 days and annual servicing are conditions, and "Grant heat pumps should be serviced annually. Failure to do so will invalidate the product guarantee." Afinia aluminium radiators: "Grant offers a 15 year guarantee with our Afinia range." These Aerona³ units run R32 refrigerant, so the installer/servicer credential that protects both compliance and warranty is F-Gas certification (see facts), not RGII or OFTEC.	Grant Ireland
Firebird	Irish-manufactured oil boilers. Firebird's own Terms & Conditions of Warranty state: "a comprehensive, conditional warranty of 5 years on the boiler shell and 2 years on all other parts from date of installation, provided installation has occurred within 12 months from date of purchase." The oil BURNER is warranted separately and much more briefly: "a comprehensive, conditional 1 year warranty on the burner from date of installation", and "The 1 year burner warranty consists of parts only."	The labour split inside the shell warranty is the part homeowners miss: "The 5 year boiler shell warranty consists of parts and labour for the first 3 years and parts only for years 4 and 5" — so in years 4-5 the technician's time is the homeowner's cost even on a valid claim. Conditions: the boiler "will only apply if the boiler is commissioned by an OFTEC registered or competent, qualified engineer and is serviced annually thereafter", and the commissioning certificate inside the Boiler Passport must be "returned to Firebird within 28 days of complete installation and commissioning" — a 28-day clock, not the 30 days the gas brands use. Excluded: "Consumable components, the nozzles and the oil hose". Incorrectly sizing the expansion vessel on a pressurised system "may damage the boiler and invalidate the warranty". Other Firebird lines follow the same 5-years-shell / 2-years-parts pattern: biomass boilers 5 years on the boiler shell and 2 years on all other parts; stoves 5 years on the stove shell and 2 years on other parts; solar 5 years on collectors and 2 years on all other parts.	Firebird Ireland
Worcester Bosch	Gas boilers, standard guarantee as published on the Irish site: Condens 8000 range 8 years; Condens 4000, Greenstar CDi Compact, Greenstar i System Compact, Greenstar Ri and Ri Compact all 7 years. OIL boilers are the outlier — Greenstar oil boilers carry only a 2-year standard guarantee, materially shorter than any of the gas ranges above.	Extended cover works as a single conditional ladder per range — standard term, a middle tier for fitting a Greenstar System Filter, and a top 'extended' tier that requires the filter AND a qualifying installer; it is NOT reachable by accredited installation alone. Gas ranges: Condens 8000 range 8 years standard, 10 with a Greenstar System Filter, 12 extended; Condens 4000, Greenstar CDi Compact / i System Compact and Greenstar Ri / Ri Compact all 7 years standard, 8 with the filter, 10 extended. Greenstar OIL: 2 years standard, 5 with the filter, 7 extended — the filter is worth three extra years on an oil boiler versus one on most gas boilers. The published condition for the top tier is worded identically across every boiler range: "The extended guarantee length can be achieved when installing the boiler with any Greenstar System Filter by a Worcester Bosch Accredited Installer or Worcester Bosch Accredited Partner. If your installer is a member of our loyalty programme but is a non-Worcester Accredited installer, they can achieve the extended guarantee length with an additional £40 payment via their loyalty account." So the extended tier = the Greenstar System Filter fitted by an accredited installer/partner (or by a loyalty-programme non-accredited installer paying the £40); accredited installation on its own, without the filter, does not reach it. Bosch-branded air conditioning on the same Irish site is the exception where an installer credential alone lifts the term, because there is no boiler-style filter on an AC unit: Climate 3200i 5 years (no uplift published); Climate 7000i 5 years standard, 7 years when installed by a Worcester Bosch accredited installer/partner. Refrigerant-circuit work on the AC units is F-Gas-gated (see facts).	Worcester Bosch Ireland
Vaillant	Vaillant publishes one domestic boiler guarantee document for these islands and it names Ireland explicitly: "The guarantee is valid for installation in domestic dwellings in the United Kingdom and the Republic of Ireland, Isle of Man and Channel Islands." If the boiler is not registered in time, the term collapses to a base year: registration "must be registered within 30 days of installing the appliance", failing which the guarantee runs only "12 months from date of installation."	Unusually for this vertical, the cover is not parts-only: "The guarantee will cover material and labour charges to repair or replace components within the boiler against manufacturing defects from the installation date." Continuing conditions: the boiler "must be serviced annually", and installation and commissioning must be done by a registered gas engineer. CAUTION for Irish readers — the installer clause in this document is drafted around the UK register (Gas Safe). In the Republic of Ireland the equivalent and legally required credential is RGII registration, so an Irish install satisfies this condition via a Registered Gas Installer, not a Gas Safe number. Per-model guarantee lengths are marketed in the UK press but are not stated in this document, so no per-range year figure is asserted here for Ireland.	Vaillant
Baxi	Baxi's Irish site scopes its headline warranty figure to boilers only: "We are so confident in the reliability and quality of our boilers that we offer warranties of up to 10 years." The page title also covers cylinders and air source heat pumps, but that 10-year figure is not stated for them, so it is not asserted for anything other than boilers here. Per-range year figures are published for the UK ranges but were not found stated on the Irish site, so none is asserted here as an Irish term.	The Irish professional warranty page sets three conditions and they are all homeowner-visible: "Warranty must be registered within 30 days of installation or commissioning as applicable"; "Benchmark should be completed and kept in a safe place" (the commissioning logbook the installer fills in); and "Product must have an annual service inline of manufacturer's instructions." Air source heat pumps are governed by a separate document — the Irish page directs the reader to "our Domestic Air Source Heat Pump Warranty terms and conditions" — rather than by the boiler terms, and no year figure for heat pumps is stated on the page.	Baxi Ireland
Vokera	Vokera's Irish warranty portal does not publish per-model year figures on the page itself, so none is asserted here. What it does publish is the downside condition, and it is severe: "Should either of these conditions not be met the period of warranty will extend to only 12 months from the date of installation."	The stated continuing condition is explicitly Irish and names the Irish register, not the UK one: "To qualify for the full period of warranty; the boiler must be serviced annually by a Registered Gas Service Engineer (RGI)." Vokera products in the Republic of Ireland are distributed by Viridus Energy, which handles Vokera sales and service for the market.	Vokera Ireland
Daikin	THIN ENTRY — flagged deliberately. Daikin's Irish service site states only that it offers "a range of standard warranties covering our air conditioning, applied, refrigeration and heating equipment" without publishing a year figure on that page. No number is asserted here, because the US Daikin figures (10/12-year registered parts terms) are American terms and would be false if presented as Irish.	The Irish page does name the extension route: "If you have a Daikin Altherma or Hybrid heating system, you may qualify for a warranty extension through our Stand By Me programme", Daikin's registration platform for tracking registration documents, maintenance records and service history. The length of that extension is not stated on the Irish page and the deeper Stand By Me pages were not reachable. Daikin heat pumps and AC run on fluorinated refrigerant, so in Ireland their installation, servicing and repair are gated by F-Gas certification (EPA-enforced) rather than by any gas or oil register (see facts).

What a home warranty costs Estimated

A home warranty is an optional annual service contract sold by third-party companies (separate from the manufacturer warranty). Generic industry ranges — not tied to, and not an endorsement of, any provider:

Annual premium: — for typical plans that include HVAC coverage; higher-coverage comprehensive plans run —.
Service (call-out) fee: — per visit, paid on top of the premium each time a technician comes out.

What can void a warranty

General consumer-protection facts, not legal advice:

In the Republic of Ireland the manufacturer guarantee is NOT the homeowner's main legal protection — the Consumer Rights Act 2022 is, and it runs against the SELLER, not the manufacturer. Under the Act (applying to goods bought from 29 November 2022), a fault in the first 30 days gives a right to terminate the purchase and get a full refund; after that the consumer can generally choose between repair or replacement; for the first year the law presumes the fault existed at purchase and "It is then up to the business to prove that the item was not faulty when you received it"; and rights can run up to six years after purchase where a product should reasonably last that long. Critically, the CCPC states a manufacturer guarantee is "an additional protection and you don't have to use it. Your consumer rights mean the business that sold you the goods is still responsible for resolving any faults and it can't tell you to contact the manufacturer instead." So an Irish homeowner whose 2-year Greenstar oil guarantee or 1-year Grant manufacturer's warranty has expired has not necessarily run out of remedies. — Competition and Consumer Protection Commission
Gas warranty conditions in Ireland are gated by RGII — the Register of Gas Installers of Ireland — and never by UK Gas Safe, even where a manufacturer publishes one UK-and-Ireland document that names Gas Safe in its text. Irish warranty and installation terms name the Irish register directly: Vokera's Irish portal conditions full warranty on annual service "by a Registered Gas Service Engineer (RGI)". The Bord Gáis Energy 10-year boiler warranty is more specific still, and its RGII requirement travels with a platform-and-date gate that must not be dropped: its terms read as two separate sentences — "The Boiler must be installed by a Local Hero who you booked through the Local Heroes website at www.localheroes.ie on or after 29 March 2021." and "The Local Hero must be a gas installer who is registered with the Register of Gas Installers of Ireland ('RGII')." So RGII registration alone does NOT confer this particular 10-year cover; it exists only for jobs originally booked through that supplier's platform on or after 29 March 2021, and the homeowner must also retain the Cert 2 ("RGII Declaration of Conformance") paperwork or face a charge if a claim is made without it. Practical consequence: on a gas job the RGII certificate is warranty-critical documentation, and an Irish homeowner should keep it with the boiler paperwork. Oil is a separate world — Firebird's oil warranty instead requires commissioning "by an OFTEC registered or competent, qualified engineer". Refrigerant-circuit equipment is a third world again: installing, servicing or repairing a heat pump or air-conditioning unit that contains fluorinated refrigerant is gated by neither RGII nor OFTEC but by F-Gas certification, which is EPA-enforced and covered as its own fact below. So the credential that protects a warranty depends on the fuel or technology — RGII for gas, OFTEC for oil, F-Gas for heat pumps and AC — not just on the brand. — Bord Gáis Energy
Refrigerant-circuit work — installing, servicing or repairing a heat pump or air-conditioning unit that contains fluorinated refrigerant — is gated in Ireland by neither RGII (gas) nor OFTEC (oil) but by a third credential: F-Gas certification. Under the EU F-Gas Regulation (Regulation (EU) No 517/2014) as implemented in Ireland, both the company and the individual technician working on stationary refrigeration, air-conditioning and heat-pump equipment must be certified; company certification is handled by F-Gas Registration Ltd and the Environmental Protection Agency (EPA) is the enforcement authority. Practical consequence for a warranty: on a heat pump or AC unit it is F-Gas certification — not a gas or oil register — that evidences a compliant install and protects cover, so an Irish homeowner replacing or repairing refrigerant-circuit equipment should confirm the installer holds it. — Environmental Protection Agency
OIL boilers get a much shorter base warranty than gas boilers in Ireland — which matters because oil-fired heating is the norm across the off-mains-gas housing stock while gas dominates the cities. Same manufacturer, same Irish price list, very different term: Worcester Bosch's Irish site gives Greenstar OIL boilers a 2-year standard guarantee against 7 years for the Greenstar gas ranges and 8 years for Condens 8000. Grant's Vortex oil boiler is "One year manufacturer's warranty with five year guarantee on boiler heat exchanger" — one year on the appliance. Firebird gives 5 years on the boiler shell but only 2 years on all other parts, and drops to parts-only (no labour) in years 4 and 5. A rural Irish household running oil should therefore expect out-of-warranty repair exposure years earlier than an urban gas household, and should treat the uplift routes as real money: fitting a Greenstar System Filter takes the oil term from 2 to 5 years, and the top 7-year tier requires that filter fitted by a Worcester Bosch accredited installer/partner. — Worcester Bosch Ireland
Two conditions void or gut almost every Irish HVAC warranty and both are the homeowner's job to keep on top of: registering the appliance within roughly a month, and an annual service every year of the term. The registration clock is 30 days for the gas brands (Vaillant: "The boiler guarantee must be registered within 30 days of installing the appliance"; Baxi: "Warranty must be registered within 30 days of installation or commissioning as applicable"; Grant heat pumps: registration within 30 days of installation is a condition of the registered guarantee term) but 28 days for Firebird oil, via the commissioning certificate in the Boiler Passport. The penalty for missing it is not a small reduction — Vaillant's guarantee reverts to "12 months from date of installation", and Vokera's states the warranty "will extend to only 12 months from the date of installation." Annual servicing is equally load-bearing: Grant states failure to service a heat pump annually "will invalidate the product guarantee", Firebird requires the appliance to be "serviced annually thereafter", Baxi requires an annual service in line with manufacturer's instructions, and Vaillant requires annual service by a registered engineer. A missed service year is therefore a real financial event, not an administrative one. — Vaillant
SEAI grant money changes the repair-versus-replace arithmetic in Ireland in a way no manufacturer warranty does, because the grant only flows one way — toward a heat pump. Effective 3 February 2026 the maximum SEAI heat pump package for a house is up to EUR 12,500, made up of up to EUR 6,500 for the heat pump installation itself, up to EUR 2,000 for required central-heating upgrades such as new radiators or pipework, and up to EUR 4,000 as a Renewable Heat Bonus for switching a home away from a fossil-fuel heating system to a heat pump. The gating condition is fabric, not appliance: the home must be "heat pump-ready", meaning a Heat Loss Indicator of 2.3 W/(K.m2) or lower, and homes built before 2007 may need a Technical Assessment where there is no valid BER showing that figure. The practical effect on an Irish homeowner staring at an expensive out-of-warranty oil or gas boiler repair is that the replacement option carries a grant the repair does not — but only if the house passes the heat-loss test, which many older, poorly insulated rural houses do not without insulation work first. SOURCING NOTE: SEAI's own grant page (seai.ie) and citizensinformation.ie both returned HTTP 403 to automated fetching — re-confirmed 2026-07-20 — so no SEAI primary page could be captured; the figures here are instead corroborated across two independently fetched Irish sources that agree on the EUR 6,500 / 2,000 / 4,000 / 12,500 breakdown, the 3 February 2026 effective date and the 2.3 W/(K.m2) Heat Loss Indicator threshold. Reporting that SEAI ceased funding oil and gas boiler installations from 1 January 2025 could not be confirmed from a fetchable primary source and is therefore deliberately omitted rather than asserted. — Irish Examiner
An Irish homeowner can hold two different, easily confused warranties on the same boiler: the MANUFACTURER guarantee, and a separate installer or energy-supplier warranty sold alongside the installation. They cover different things and expire on different terms. The Bord Gáis Energy 10-year boiler warranty, for example, is a supplier product that will "repair or replace the boiler or parts free of charge during this 10 year period", but is conditional on the boiler having been originally booked through that supplier's Local Heroes platform on or after 29 March 2021 and installed by an RGII-registered installer, on the customer retaining the Cert 2, and on annual servicing by that supplier — the cover lapses if a service is not booked within 15 months of installation or of the last service, and while the first service is free, later ones are charged at standard rates. Its exclusions are broad and include normal wear and tear, system de-sludging, heat exchanger replacement caused by poor water quality, and external components such as pumps, expansion vessels, radiators and pipework — which is to say several of the most common Irish heating repairs sit outside it. A homeowner should check which of the two documents actually covers a given failure before assuming a repair is free. — Bord Gáis Energy
Where a manufacturer publishes a single guarantee document covering both the UK and the Republic of Ireland, the Irish terms are the same length but the qualifying credentials differ, and the difference is not cosmetic. Vaillant's guarantee is stated as "valid for installation in domestic dwellings in the United Kingdom and the Republic of Ireland, Isle of Man and Channel Islands", yet its installer clause is drafted around the UK register. Irish gas work is legally gated by RGII registration, so in Ireland it is the RGI number and the RGII Declaration of Conformance that evidence a compliant install for warranty purposes. Do not read a UK-facing Gas Safe reference as meaning an Irish install needs a UK credential, and equally do not read a UK-published per-model warranty length as an Irish figure unless the Irish site states it — Worcester Bosch, Baxi and Vokera all run separate Irish sites and Irish registration portals for exactly this reason. — Vaillant
