"The initial install was fine, though it was REALLY difficult getting a firm price once Tim was on site. I still do not have information on what brand/type of whole house charcoal filter system was installed, and Maintenance Express is insisting that I buy filters through them. When Tim came out to do a checkup on the water softener system, he tried to charge me $150 to also deliver $100 worth of salt ($20 per bag for Morton salt which is $7/bag at the grocery store, so that is a ridiculous markup). Will be finding someone else for the maintenance of our system."

"I’m extremely satisfied with Regional. We had three sump pumps that needed to be replaced (primary, secondary, and water powered backup). The quote was very reasonable, and they were able to do the work shortly after their initial visit. They replaced everything with Liberty pumps. Justin and Erich did the work and they were very professional. We had them quote out a couple of other items (replacing water heater, etc) and those quotes were also very reasonable. I will definitely hire them for future jobs."

Boiler Repair questions, answered by experts

Air trapped in a heating system can lead to reduced efficiency, uneven heating, increased wear on components, strange noises, and even complete system failure. This trapped air disrupts proper circulation, strains parts, and can cause overheating. Regularly bleeding baseboard heaters and furnaces can prevent these issues, ensuring efficient operation, even heating, and prolonged equipment life.

Over time, a radiator can leak if turned off due to the built-up air pressure, which can cause water or coolant to leak. If your radiator leaks when it’s off, turn your whole system off and bleed the radiator, then turn it back on. If it’s still leaking, you might want to have an HVAC professional look at the issue.

One of the most common signs you’re dealing with a bad thermocouple is the pilot light for the water heater will continuously go out. For example, you may light the pilot light and then have to re-light it a few days later. You can also look at the thermocouple for a visual inspection. If you notice discoloration, cracks, holes, or other damage, then you know it needs replacing.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

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.
