Len The Plumber, LLC. is a leading plumbing and drain company serving Central Maryland. Our certified professional plumbers are available same day to assist residential customers in Anne Arundel County, Baltimore City, Baltimore County, Carroll County, Cecil County, Harford County, and Howard County. Our knowledgeable plumbers have years of experience dealing with a wide variety of plumbing issues including plumbing repairs, drain cleaning, water heaters, well systems, heating systems, sewer, water, and gas lines. We’re open 7 days a week with no extra charge on evenings or weekends!

"Our first encounter with Len the Plumber for gas boiler repairs went well and lead us to purchase a service contract with them for the 15% discount. However once we needed actual plumbing services and after they provided their "free" HVAC annual inspection it all went downhill rapidly. As others have noted the %15 discount is a concept they don't really honor. We were charged $1100 for less than 30 minutes of work for a repair that only required one cut and a simple joint (We had already removed the drywall and trim for access) and about $30 in parts (which by the way good luck getting an itemized bill from these people). On the HVAC side they broke what was a perfectly functioning 4 yr old AC HVAC and then wanted to charge $1200 to figure out how they broke it plus whatever parts they dreamed up needed replacing. They tried to claim the capacitor was bad. BTW - they brute force discharge the capacitors on units as part of their "maintenance check", something they should never do. We had BGE come out since their info was on the installation tag on the air handler and they diagnosed the issue in less than 30 minutes finding the thermostat had been burned up by mis-handling by the Len tech. They also said they never brutalize the capacitors the ways these guys do unless there is already a suspected issue with it. That's because the capacitor could be damaged by the way they handle it at Len the Plumber. So the "free" annual HVAC check cost me 3 days of discomfort and $250. Len refuses to admit wrong doing and will not reimburse us. They got $5000 in fees from us in less than a year so they don't care if we leave because they know another sucker is just around the corner waiting to be taken. These guys should lose their license given their business practices. Stay away from them at all costs."

Install Boiler questions, answered by experts

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

The right type of HVAC system will depend on several factors, including your climate, budget, preferences, and existing HVAC setup. For example, if you live in an area that experiences extreme weather, then a split system would likely be the best option. Or, if budget is a concern, consider installing a ductless system in just one room.

By submitting this question, I acknowledge and agree that Angi may publicly display my name, city, state, and question on the website for professionals and others to see.
