Heating and HVAC problems we hear most
In the UK, “HVAC” often means boilers, radiators, heat pumps and increasingly air-conditioning units. Searches for heating engineers spike in winter; cooling repairs rise in summer. Fast triage matters when you have young children, elderly relatives or work-from-home needs.
- Boiler lockouts, error codes and no hot water
- Cold radiators or uneven heating
- Thermostat and smart heating issues
- Air-conditioning not cooling or leaking
- Heat pump performance problems
Gas Safe and system type matter
Gas boiler work must be done by a Gas Safe registered engineer. Note your boiler brand if known (Worcester, Ideal, Vaillant, Baxi and others are common in UK homes), any error code on the display, and whether you smell gas — if you do, follow National Gas Emergency guidance immediately.

Frequently asked questions
My boiler shows an error code — what should I do?
Note the exact code and any recent power cuts or pressure changes, then start a HelpNHelp chat. Do not keep resetting a boiler that keeps locking out.
Can HelpNHelp help with air-con as well as boilers?
Yes. Describe whether you need heating, cooling or both, and the type of system if you know it.
