"I had them replace my entire HVAC system (furnance + AC). They did a great job through the whole process. Out of four quotes I received, they were the only ones that took the time to do a full heating and cooling load calculation for my house when they came to do an estimate in addition to making detailed measurements of our utility room to make sure anything they installed would fit. They gave me three proposals ranging from low-end, mid-range, and high end options and explained the equipment in each of them in detail, including documenting all the model numbers, efficiency ratings, and specs. What they recommended matched up with my research I did prior to receiving estimates. They were very responsive, knowledgeable, and professional so I gave them the job. The crew arrived on time, worked hard the whole day, were respectful of my house, and did not require supervision (although, they told me I was more than welcome to ask questions and watch anything they were doing). They cleaned up, explained the warranty and rebate options with all the paperwork already filled out so that all I had to do was sign--they even mailed both the warranty and rebate off for me. The whole process went great. While their prices were fair they were not the cheapest, but I have no doubt they did a great job, didn't cut corners, and will stand by their work if I experience any problems. They are a reasonably sized HVAC business and not a one-man-band shop like many places in the area, so I know they will likely still be around through the life of the warranty and are well staffed to respond to emergencies, including a 24/7 emergency service number. Overall, we're very happy with the new system and it's a huge improvement over what it replaced--both the AC and furnace are much quieter than the old units, more energy efficient, and perform better. It's been a month since the install and everything has been working fine without problems."

"March 2024 I contacted JDL because my very old boiler (radiator heat) was making very loud noises, leaking water and the radiators were not heating up as they should have been. Tech [Provider Name Removed] came out, he was very professional, very knowledgeable, and very respectful of my home. He inspected the boiler in detail to determine the cause of the problems. He determined that several parts needed replacing. He worked diligently on replacing the parts on the boiler. My boiler is now working better than it has worked in years: it is running quietly, no water leaking, and radiators are putting out good heat. I highly recommend JDL HVAC and Plumbing Services."

"Although we had a bit of a hiccup in the beginning, he made sure the service was completed. The service was completed when other company’s had zero availability since my request wasn’t considered “emergency”. Much appreciated MSR!"

Boiler Repair questions, answered by experts

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.

When it comes to bleeding a radiator, the goal is to let out trapped air rather than letting out the water. Naturally, some water will dribble out when you open the valve to let out the air. But you don’t want a lot of water to leak out. Just leave the valve open long enough that the hissing noise stops, meaning the air has escaped, and just a dribble of water comes out of the radiator.

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.

If you have multiple radiators, start by bleeding a first-floor radiator that is farthest from the boiler. Work your way toward the boiler on the first floor before moving to the next floor, where you’ll again start by bleeding the radiator farthest from the boiler. Continue this pattern for radiators on each floor until they’ve all been bled.

Although boilers can last 15 to 20 years when maintained properly, you may run into some common problems like oil burners and transformers malfunctioning; cracks in the heat exchanger; clogs in the heating oil pump, burner nozzles, or fuel pipes; loose wiring connections; and damaged valves. Many of these problems can be caught early on during annual maintenance services. You might also have an issue with your fuel source if you have a gas or oil boiler. Make sure your other gas appliances are working or that you have oil in your tank.
