Central heating repair in Coventry for cold radiators, noisy pipes, leaks and systems that keep losing pressure. We find the cause before fixing anything, and there's no call-out charge.
Radiators that are cold at the top usually have trapped air, while ones that are cold at the bottom often have sludge. Other common faults include a sticking pump, a zone valve that won't open, leaks at radiator valves and pressure that drops every few days.
On a sealed system, pressure that keeps dropping means water is escaping somewhere. It could be a weeping radiator valve, a leak under the floor or a faulty pressure relief valve. Topping it up keeps it running, but the leak needs finding before it causes damage.
Over the years, sludge builds up inside radiators and pipes and blocks the flow. A power flush pumps cleaning chemicals through the system at speed to clear it out. It's worth it if several radiators have cold spots, the water runs dark, or the heating takes ages to warm up.
We start by asking what the heating is doing and when the problem started. Then we check the system pressure, feel for cold spots on each radiator and test the pump and valves, so we fix the real cause rather than the symptom.
Once we've found the fault, we explain it in plain words and give you a free quote. After the repair, we refill and bleed the system if needed, check every radiator heats up properly and leave the pressure at the right level.
Tell us about the leak, fault or project. We aim to respond the same day, and there's no call-out charge.
We look at the job in person and give you a free, no-obligation quote before any work starts.
We finish the job, test everything we have fitted and certify the work before we hand it back to you.
Usually it's trapped air, a closed valve or sludge in that radiator. Bleed it first and check both valves are open. If it's still cold at the bottom after that, sludge is the likely cause, and the radiator may need flushing or the whole system cleaning.
It depends on the fault and the parts needed. Bleeding radiators or replacing a valve is a small job, while a new pump or a power flush takes longer. We find the fault first, then give you a free quote so you know the cost before we start.
It's worth it if your radiators have cold patches at the bottom, the water is dark when you bleed them or the heating is slow to warm up. On a newer, clean system it usually isn't needed. We'll check the system first and tell you whether it's needed.
Gurgling usually means air in the system, which bleeding the radiators can fix. Banging can come from sludge or limescale restricting the flow, a pump running too fast or pipes that aren't clipped properly. We can track down the noise and fix the cause.
