"Everyone that we dealt with couldn?t have been nicer. We had a tub to shower conversion which was completed in one day. Matt, the installer, laid a tarp down from the door to our bathroom to protect the floors. He asked for our input when he was installing the shelves and grab bars. After he finished cleaning everything up he explained how to used the new shower head and what to use to clean the surface. The next day we texted him with a question and he immediately answered. We couldn?t be happier with the job done and the professionalism of the company."

"Technician Jim was not impressive. Was not confident when answering the questions I asked. Very contradicting.. Tried to sell product for items that were not even in need of repair. Spoke negatively about the company and made excuses as to why he could not perform his job due to lack of information from dispatch or technician manager. Said he would follow up, I never heard from him. Blessing to me, I decided to go with another HVAC company. I typically would not put names out there, but please be careful if you get this gentleman as a technician."

Boiler Repair questions, answered by experts

The best way to save money on home heating oil is to get large deliveries in the summer months when the prices are lowest. However, this method will only work if you have a separate storage tank or an unusually large primary tank. You can sometimes save money by opting into a delivery contract, as some companies offer set prices that they believe will sit at the average cost over the contract term. If the price of oil rises, you could enjoy some savings, but keep in mind that you might also pay a bit more if the price decreases.

Annual servicing, checking for leaks, and maintaining proper pressure extend the system’s life.

Boiler leaks are the most common problem that impacts this fixture. Some leaks stem from corroded pipes and tanks, while others are due to damaged seals or excessive pressure. No matter how you slice it, boiler leaks are bad news. This issue leads to water damage in the home and malfunctioning electrical components in and around the boiler.

DIY troubleshooting is possible for minor issues like bleeding radiators or resetting the system, but professionals should handle complex repairs to ensure safety and efficiency.

Blockages can occur for various reasons, primarily linked to the accumulation of debris or substances within the heating system. Common causes include the buildup of sediment, rust, or mineral deposits inside the boiler or its pipes, hindering water flow and heat transfer. Additionally, air pockets or trapped gasses can impede circulation. In central heating systems, sludge or corrosion within radiators can obstruct the flow of hot water. External factors like frozen pipes in winter can also lead to blockages. Regular maintenance will help prevent blockages and ensure efficient boiler operation.
