Boilers, heat pumps and air conditioning.
How to choose · Heating, ventilation and cooling
Choose by the building first, then the equipment. Insulation, air tightness, existing distribution (radiators, ducts or underfloor), climate and fuel access set what is practical. Size the system from a proper heat loss calculation rather than the old unit's rating, and compare running cost, comfort, noise, maintenance and installer competence alongside purchase price.

Comparison · Heating, ventilation and cooling
A heat pump moves heat from outside to inside and typically delivers several units of heat per unit of electricity, but it works best with good insulation and low-temperature emitters. A gas boiler is a simpler swap with familiar controls, but ties you to fuel price and policy exposure. The answer depends on your building, local energy prices, available incentives and long-term plans.
Problems & fixes · Heating, ventilation and cooling
Many problems stem from restricted airflow, dirty filters, poor sizing, refrigerant or water leaks, thermostat settings and neglected maintenance. Uneven rooms and short cycling often point to design or ductwork issues rather than a failing unit. Safe checks include filters, vents, thermostat batteries and breakers. Gas smells, burning odours and carbon monoxide alarms demand immediate safety action and a qualified professional.
Requirements · Heating, ventilation and cooling
Heating and cooling work often involves gas, electricity and refrigerants, so many jurisdictions require licensed or registered installers, building permits and inspections. Refrigerant handling and gas work are typically regulated separately. Ask to see credentials, insist on permits being obtained, keep commissioning records and confirm warranty conditions. Requirements vary by country and region, so check with your local building or licensing authority.
