"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."

"Guy that came out said that it was an issue of the boiler not having enough water. He turned the valve to force water to it and and ended making a mess in my basement floor of black gunk water that I had to clean up. Idk if that was necessarily the issue, he said that’s all it was and nothing else needs to be done. He didn’t provide any type of explanation as to why it wasn’t getting enough water when turned on as this is something that should be self regulated, not something I should have to monitor anytime I turn my heat on. I won’t even necessarily know if this is the case and it’s fixed until fall rolls around again and we need heat, as it is now warming up. I hope that he was correct but quite pessimistic, and felt that a more thorough check should of been done."

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

Boiler Repair questions, answered by experts

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water. 

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

Repair costs range from $200 to $800, depending on the issue and required parts.

In general, it’s a good idea to bleed air from your heaters at the start of every cold season, before you move your boiler system back into active mode. Early fall is a common time for this task. However, some heating systems don’t need much manual bleeding because of automatic bleed vents and other components.

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