Frequently Asked Questions
Radiator heat can be more expensive to install than forced-air systems due to the materials and technology involved. However, radiators often provide superior warmth and can improve indoor air quality by not circulating allergens. While the upfront costs may be higher, the enhanced energy efficiency and lasting performance can make radiators a worthwhile investment for a comfortable home.
If one radiator in your home isn't heating up, it might be due to trapped air or a blockage from debris or sludge. Your pro can bleed the radiator to release any air pockets. If that doesn't work, it might need a thorough cleaning or professional inspection. Regular maintenance helps prevent these issues and keeps your heating system running smoothly.
If your radiator is making banging, clanging, or hissing noises, it might have trapped air or loose parts. Your pro will likely start by bleeding the radiator to release any air pockets. Next, they’ll check that all valves, brackets, and pipes are securely tightened. Adding insulation can also help reduce noise. If the sounds persist and your pro recommends it, a replacement may be necessary.
