How much does boiler repair cost in Des Plaines?

Most boiler repairs in Des Plaines run about $210 to $940, depending on the part and whether it is a cast-iron or condensing unit.

What pressure should my boiler run at?

Most residential boilers operate best around 12 to 15 psi when cold. Pressure that keeps dropping usually points to a leak or a failing relief valve.

Why are my radiators cold at the top?

That is usually trapped air, which is cleared by bleeding the radiators. If it keeps happening, the system may need rebalancing or have a circulation problem.
