"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."

"It was a pleasure hiring Sean. He was able to install our new thermostat which involved updating the wiring and removal of a module. Another company was unable to perform these tasks to get the HVAC running but Sean quickly resolved the issue. He was very friendly, knowledgeable, and punctual. Don't miss out on hiring Simply Home services, you won't regret it."

"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!"

"I had a leak somewhere in my heat pump system from 2013 in a 4 floor condo building. Every other company was quoting me $7k+ to replace the system but it turns out to be a leak in the line set between the 3rd floor and the roof! We had a new line set installed and I spent $2550 in total! The crew was very professional and worked extremely had in the hottest weather to get the job done, too!"

Boiler Repair questions, answered by experts

Signs of needing a new expansion tank include visible leaks and a dull sound when you knock your knuckles against the tank (working tanks should sound hollow). A malfunctioning tank may also sweat with condensation, cause pipes to create loud noises when the system is turned off, and lead to very high-pressure readings on the boiler’s gauges. When in doubt, call for a professional inspection to find the source of the problem.

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.

Chilled water HVAC systems use water instead of traditional components and refrigerants. They're more common in commercial settings than residential ones but are slowly being adopted by some homebuilders to cool homes. As the name implies, the system keeps the water chilled at 40 degrees and circulates it through water coils. The water absorbs the heat from your home and drains outdoors. Condo apartments are more likely to have chilled water HVAC than single-family homes because this system is designed to cool several rooms or large areas individually.

If you hire a professional to replace your gas furnace’s thermocouple, you’ll usually pay between $150 and $250. Since thermocouples often fail due to a lack of maintenance, you may be able to avoid—or at least delay—a thermocouple replacement by taking good care of your furnace. This means scheduling annual furnace inspections, changing the filters at least once per season, and cleaning the burners occasionally.

Pipes in your house can freeze after six hours or so if you lose power and temperatures are below freezing. You can prepare for potential power outages by winterizing your pipes with insulation. Also, whenever temperatures drop below 20 degrees Fahrenheit, turn your faucets on very low and leave them dripping until temperatures rise.
