FAQs

Boilers are constantly exposed to oxygen and water — the perfect combination to encourage corrosion. Their high temperatures and mechanical stress speed up the corrosive mechanism, particularly if your water is alkaline.

Clanging and banging are usually signs of a disrupted fan. Your blades could have loosened, but your crankshaft or piston pin might also be to blame. In the worst-case scenario, the entire compressor could be loose. Loose components can cause severe damage, so turn off your AC at the first sign of noise.
