Heat pumps and domestic air conditioning are systems, not appliance swaps. Heat loss or cooling load, emitter size, controls, outdoor-unit location, pipe routes, condensate, noise and electrical supply all affect suitability.
This is the LP10 starting guide to domestic heat-pump and air-conditioning work. It combines the main questions customers search for into one substantial page instead of creating many lookalike pages. Use it to identify the job, gather evidence and compare scopes. It does not diagnose a property remotely or promise that a provider is currently available.
Jobs and decisions covered in this guide
- Is an air-source heat pump suitable for this home?
- Heat pump heating or split air conditioning?
- Radiators, underfloor heating and heat-pump flow temperatures
- Heat-pump and air-conditioning service, faults and noise
The sections below deal with each of those searches in context. Closely related wording belongs on this page so the customer and search engine reach one clear answer rather than several pages competing with each other.
Define the complete scope first
A domestic heat-pump and air-conditioning enquiry may involve several connected tasks. Mark every item below as required, optional, already complete or unknown:
- Survey, heat-loss or cooling-load assessment and room outcomes
- Indoor and outdoor units, cylinders, emitters and controls
- Refrigerant or water pipework, drainage and electrical supply
- Bases, wall penetrations, noise, airflow and planning constraints
- Commissioning, balancing, user handover and maintenance
Also identify anything that must remain untouched. This stops the visible finish being priced while access, preparation, testing, disposal or reinstatement is silently left for somebody else.
Is an air-source heat pump suitable for this home?
The decision: Testing heat loss, emitters, hot-water needs, outdoor space, noise and electrical supply before equipment selection.
Most avoidable delays come from missing decisions, hidden preparation or one trade arriving before another has completed enabling work. Agree who surveys, who supplies, who prepares, who tests and who finishes before accepting a start date.
Keep this part of the enquiry separate enough to compare. Record the present condition, the outcome required, products already chosen and anything that must be prepared or reinstated. Ask the provider to state what evidence or visit is needed before the method and price become firm. If connected work changes the sequence, put that dependency in the written scope rather than relying on an assumption.
Heat pump heating or split air conditioning?
The decision: Distinguishing whole-home hydronic heating from room-based air-to-air heating and cooling by outcome and building needs.
A useful comparison holds the job requirements constant and then tests each option against condition, performance, maintenance, disruption, appearance and compatibility. A product is not automatically better simply because its headline specification is higher.

Radiators, underfloor heating and heat-pump flow temperatures
The decision: Coordinating heat emitters, zones, pipework and controls around a lower-temperature heating design.

Heat-pump and air-conditioning service, faults and noise
The decision: Recording performance, alarms, condensate, airflow and noise while keeping refrigerant and electrical work with qualified people.
Similar symptoms can have different causes. Record what happened, when it started, what still works and any recent changes. That evidence helps the attending professional plan safe checks without treating an online description as a diagnosis.

Details that can change the method or quotation
- Property fabric, room sizes, glazing and occupancy pattern
- Existing boiler, cylinders, radiators or underfloor heating
- Outdoor space, neighbours, access and pipe-route length
- Heating flow temperatures, hot-water need and cooling zones
- Electrical capacity, controls and making good
Measurements help an initial response, but condition often determines the final method. Give dimensions as approximate unless verified. Product links, complete model numbers and drawings are more useful than “standard”. State any deadline and why it matters, then let the provider confirm a realistic sequence after checking dependencies.
Evidence to send with the first request
Clear, current evidence reduces avoidable messages and helps a suitable provider decide whether a visit is needed:
- Floor plans or room dimensions and property construction
- Energy information and existing heating-system details
- Photographs of emitters, cylinder space and outdoor positions
- Desired room temperatures and usage patterns
- Known noise, planning, electrical or access constraints
Include the full postcode, property type, occupancy constraints, parking or access limits and the safe entry arrangement. Do not upload passwords, security codes, identity documents or unrelated personal information. If something cannot be photographed safely, describe it and leave the inspection to the professional.
How to compare written quotations
Compare scope before price. Look for the proposed method, materials or performance specification, preparation, protection, waste handling, testing, making good, exclusions, payment stages and how variations will be approved. Check whether the figure follows a site visit or remains provisional. Confirm who buys each product and who carries the risk if a customer-supplied item is unsuitable, damaged or delayed.
Check the competence, registration, insurance or certification relevant to the exact task rather than assuming one credential covers every service. For regulated work, ask what notification, inspection, certificate or record applies and use the official sources on this page to verify the route.
Trade boundaries and connected work
Refrigerant handling, electrical connection and gas-appliance alteration require appropriately qualified specialists. Performance and running costs should not be promised without a property-specific design and operating assumptions.
Electricians, plumbers, heating engineers, builders and insulation specialists may need a coordinated programme. Any retained boiler, cylinder, solar or smart-control interface must have a named owner.
Where more than one trade is needed, request one joined-up sequence with separate written scopes. LP10 can receive a bundled enquiry, while each provider remains responsible for confirming their own availability, competence, method and quotation.
Useful next step
Write a short outcome statement, attach the evidence above and separate must-have work from optional work. Read the Heat pumps & air conditioning service overview, explore connected help from insulation and electrical services, or send one or several trades to LP10 for a quote.
