"Our brand new system was not heating properly. Gary (FIVE STAR EMPLOYEE) came and fixed a problem. It was not straight forward and he had to do a bit of research, but he made it work better than it ever had!. He came back the next day and changed the filter and rec-hecked the system. We were warm and snug after his dedicated service! Thanks for the GREAT experience."

Boiler Repair questions, answered by experts

Regular maintenance includes annual inspections, filter changes, and checking for leaks or pressure inconsistencies to improve efficiency and longevity.

Deciding whether to repair or replace your HVAC system largely depends on its age, the cost of repairs, and its overall performance. If the system is over a decade old and requires frequent or expensive repairs (e.g., totaling over $5,000), replacement is often the more cost-effective choice, especially if the warranty has expired. It is usually worth repairing a newer system, but if it is approaching the end of its typical 15- to 25-year lifespan, replacement might be a better long-term investment. Signs that you may need a replacement include increased humidity, higher energy bills, uneven heating or cooling, and excessive dust. Before deciding, ask your HVAC contractor to check if any parts are covered under warranty, which could save you money on repairs.

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.
