Heating, Boiler & HVAC Repairs
If your boiler has stopped heating, your radiators stay cold or your heating or air-conditioning system has developed a fault, call Alderminster Group. We diagnose the cause, explain the repair and provide a written quotation before work starts.
Heating Problems
When heating fails in an older or rural home, we find fault, restore safe operation and explain next steps clearly.
Boiler, Heating and HVAC Repairs
When your boiler leaves rooms cold, hot water fails, or a heat pump stops performing, we trace the fault rather than replace parts blindly. We repair heating controls, radiators, underfloor heating, air-conditioning and pipework, including leaks, circulation faults and noises.
Older homes can need different checks. We test the system afterwards and explain further work before you decide.
Boiler fault finding
A boiler that cuts out, loses pressure or fails to provide hot water needs more than a reset. We test the controls, safety devices and system pressure to identify the cause before recommending a repair.
Controls and radiators
Uneven temperatures, stuck valves or unreliable thermostats can make a working boiler feel ineffective. We repair controls, radiator valves and circulation faults so the system responds properly.
Heat pump repairs
A heat pump that runs continuously, makes unusual noises or produces little heat needs system-specific checks. We assess the controls, flow temperatures, emitters and pipework before explaining the practical next step.
Air-conditioning faults
Poor airflow, unexpected noise or inconsistent room temperatures can point to a control, electrical or refrigerant-related fault. We diagnose the equipment and explain which repairs are appropriate.
Older property checks
Solid walls, older radiators and oil or LPG heating can affect how a fault presents. We consider the whole system and the property's existing pipework rather than treating one component in isolation.
Clear repair decisions
Once we know what has failed, we explain the repair, any related work and the likely disruption. You receive a written quotation before work starts, with no surprise charges.
What We Check During a Heating Repair
Once we identify the fault, we fit suitable replacement parts, test safety controls and confirm the system operates correctly. You receive a clear record of the work, advice on preventing repeat faults and a written price for any additional repair.
Fault-Finding Across the System
Cold radiators, fault codes or weak airflow can have several causes. We test the boiler, pump, controls, valves and connections to identify the fault rather than replace parts by guesswork.
Repairs for Older Properties
Older homes may have mixed pipework, ageing controls or oil and LPG heating. We assess the existing system carefully and recommend repairs that suit the property and its current equipment.
Gas and Oil Safety
Gas boiler repairs are carried out by Gas Safe engineers. Oil-fired heating is handled by OFTEC-registered engineers, so the work follows the requirements for the fuel your property uses.
Heating Controls and Electrical Faults
A failed programmer, thermostat or wiring fault can leave a working boiler unable to heat the home. Our heating engineers and NICEIC-registered electricians can trace connected electrical faults as part of the repair.
Testing Before We Leave
Once the repair is complete, we run the heating or air-conditioning system through its controls and operating cycle. We explain what we have found, record the work and flag any further issue that needs attention.
Heating Repair Questions, Answered
Can you repair an older boiler without replacing it?
An older boiler or heat pump isn’t automatically beyond repair. We assess its condition, available parts and likely future reliability, then set out repair and replacement options clearly in writing.
Can you fix a boiler that is not heating water?
If heating works but your taps stay cold, we check the controls, diverter valve, thermostat or cylinder. We identify the failed component, explain the repair and quote before replacing anything.
How much does heating system repair cost?
Repair costs depend on the fault, parts needed and access to the system. We inspect these factors first, then price the work clearly, helping you decide whether repair is worthwhile.
Can you repair a boiler that keeps losing pressure?
Repeated pressure loss usually points to a leak, expansion vessel or pressure relief fault. We trace the cause, check hidden pipework and explain the safe repair before proceeding with you.
What details should I provide when booking a heating repair?
Include the boiler or heat pump model, fault symptoms, display codes, recent changes and property access details. Photos of controls, labels or leaks can help us prepare for the visit.
What to Expect from a Heating Repair
Tell us what the system is doing, when the problem started and whether anything has changed recently. This helps us bring suitable parts and focus the visit on the likely cause, rather than replacing components unnecessarily.
We protect floors and surrounding surfaces, keep disruption to the work area and explain any issue that changes the scope. If a repair is no longer sensible, we set out the practical alternatives so you can decide what happens next.
Safety comes first
A heating fault can involve gas, oil, electricity or combustion fumes. We make the appliance safe before we investigate the cause.
Gas and oil heating safety
If you smell gas or suspect carbon monoxide, stop using the appliance and follow emergency safety guidance. Gas Safe registration covers work on gas boilers, while OFTEC registration covers oil-fired systems. We check the relevant flue, fuel supply and controls before recommending further work.
Repair or replacement
An older boiler may still be worth repairing, but some faults make replacement the more sensible choice. We explain the difference using the condition of the appliance and the availability of suitable parts.
A practical recommendation for your system
Your boiler’s age, repair history and likely future costs all affect the decision. We explain what the repair involves and set out replacement options when continued repairs are unlikely to be economical. You can then choose the route that fits your home and budget.
No guesswork with faults
A cold radiator, error code or noisy unit does not always identify the failed component. We trace the fault through the controls, electrical supply and heating circuit before recommending parts.
Finding the cause of the problem
Your thermostat, programmer, pump, valves or wiring may all affect how the system behaves. We use the symptoms and system layout to narrow down the cause instead of changing parts without a clear reason. This helps prevent a repeat visit for the same underlying fault.
Clear costs before extra work
A fault can reveal another issue once the system is opened or tested. We explain any change in scope before carrying out additional chargeable work.
No surprise charges
The agreed repair and its price are set out before work starts. If we find a further problem, we explain the options and provide a separate written price, so you remain in control of the decision.
Careful work in your home
Heating repairs can take place in kitchens, utility rooms, lofts or plant rooms. We plan the work around the access available and keep the affected area orderly.
What to prepare for the visit
Please keep access clear around the boiler, controls and any equipment showing a fault. Details of error codes, unusual noises and recent changes can help us understand the problem before we arrive. Our directly employed engineers work tidily and leave the area as they found it.
If the heating has failed, contact Alderminster Group with the appliance type and the fault you’ve noticed. We’ll confirm the next step and explain what we need before the visit.
After the repair, you’ll know what caused the problem, what work we carried out and whether anything else needs attention. That gives you a clear basis for deciding how to manage the system from here.
