"If I could, I would give this horrible service provider a 0.0! I scheduled a plumbing appointment on a call, which was confirmed via multiple texts the day prior to the appt. Then had an employee go to the location during the 4 hour window they specified and wait for the plumber. On the day of the appt, 1 hour into the time window someone calls and says, sorry we’re not going to go because we only do residential plumbing. This was a surprise, as it was communicated to them that this was a business when I had set up the appt. So, I decided to speak with a manager. After spending over an hour of being bounced around from one dept to another, asking for a manager, they never connected me to one and their dispatcher had the audacity to say “sorry for your inconvenience, but you’ll just have to find someone else.” WOW! The hoops they make you jump through and the rudeness is not worth the hassle. I would definitely recommend you find a different plumbing pro for your project!"

"I had an emergency plumbing situation and Jamie was absolutely brilliant. He came promptly within an hour of submitting my request and it was after hours. He was immediately able to identify the issue and suggest a corrective action. Jamie waited patiently as we spent time deciding if we wanted to follow his recommendation. All of my valves we leaking around the apartment so it was a chaotic afternoon after work and Jaime stayed absolutely calm, patient, and professional. He helped control the issue and suggest a solution to help maintain the situation overnight then came back and finished the job. Very responsive with great service and workmanship. I Recommend him to everyone I know."

Boiler Repair questions, answered by experts

Boilers provide even heating, energy efficiency, and a quiet operation compared to forced air systems.

There are a couple of signs that will tell you it’s time to bleed the radiator. If the radiator is making noises, it’s typically because of trapped air, which you can release by bleeding the radiator. You can also test the radiator by turning on your heat and then placing your hand near the top and bottom of the radiator. If you feel cold spots, particularly at the top of the radiator, it’s time to bleed it.

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.

Even if you do everything right, your boiler’s pilot light might not come on. This has a number of possible causes, but the most common is a blocked jet. These jets are small and clog up even with a small amount of debris. You can clean it yourself or hire a pro to replace the component. Other possible causes include a faulty fan and frozen pipes, among others.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.
