"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."

"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

"HPC quickly determined and resolved the cause for our problem in August. However, they also determined that we had a relay that needed to be replaced. They informed me that it would take some time to get the relay, I think they mentioned delays due to the tariff situation. They promised to get back to me when the relay came in. They jury-rigged the system to work properly without the damaged relay, but warned me that the jury-rig would malfunction badly if we switched from cooling to heating. Starting in November, we called HPC a half-dozen times over several weeks asking for the status of the replacement relay. We were told that the appropriate people would be informed, and that they would call us back with the requested information. On November 11th, I sent an e-mail containing the same information. This resulted in a response containing an estimate for something called a "heat kit". When I asked whether the "heat kit" contained the replacement relay, I got no response. "
