"Changing my 5 star review to 2 stars. We have had a HE Boiler as well as a AC/Heat Pump installed by them. Unfortunately we needed service today. I was willing to pay for Emergency service. They said they couldn't make it out for 14 days, because we did not have a service contract. Spent about $25k for the installations. Which apparently means nothing to them What makes matters worse, the Emergency Service we paid through another HVAC provider was only necessary because of an issue they created during the installation. During the installation Speer Air originally ran the line for the residual pump over the copper hot water line. Which over time burned through the residual line, and then cause a hole and leak on the copper pipe."

"Worst service I’ve ever have experienced. They wanted to sell me the product, never told me that there was an early termination fee and another penalty for an initial offer they gave me. Had double charges every month, once for the oil they provided (which they never told me they were going to provide before coming. They just came without my knowledge and then I find a high amount bill) and another for an “automatic payment” for 500 that they never could explain. The didn’t even fix this issue and it kept happening every month even after I cancelled the service. Then having to call them is a hastié for the refund of the 500. Stay away of this company"

"First of all I wanna mention that my experience is similar to many people who have been serviced by j&s as it appears in their Yelp reviews. I had a working furnace that was tripping because of limited airflow, they practically forced me to change the furnace. Which, cost me $4000 and took over 2 weeks. Then the new one had a defective gas valve. Then the furnace kept tripping and stopped working even after changing the valve. I had to reopen the work order for the 3rd time. When they came they found out about the limited airflow from the dirty coil. They said they'll talk with AHS and get back to me, but what they did is they closed the request as completed. I had to call again to reopen the request. When they showed, up they tried to talk me into downgrading my filter. It was too late when I realized that the real issue was a dirty coil and/or duckt work not the furnace. Lastly, they sneakily updated the request to have a non covered item ($200 to change the air filter) this way,"

Boiler Repair questions, answered by experts

Properly maintained stucco can enhance insulation, reducing energy loss.

Blockages can occur for various reasons, primarily linked to the accumulation of debris or substances within the heating system. Common causes include the buildup of sediment, rust, or mineral deposits inside the boiler or its pipes, hindering water flow and heat transfer. Additionally, air pockets or trapped gasses can impede circulation. In central heating systems, sludge or corrosion within radiators can obstruct the flow of hot water. External factors like frozen pipes in winter can also lead to blockages. Regular maintenance will help prevent blockages and ensure efficient boiler operation.

Attempting DIY fixes can be dangerous. Regular boiler maintenance can help prevent overheating, so schedule professional servicing as a preventive measure. In an emergency, telling occupants to leave the house is a good idea. Then, you can turn off the boiler and the gas or fuel supply. Let it cool naturally, and check the thermostat's settings. Ensure there are no obstructions around the boiler for proper ventilation. Monitor the pressure gauge; if it's too high, bleed the radiators if necessary. During this time, bringing in professionals for troubleshooting is also smart.

Generally speaking, yes, turning one radiator off does save some money, especially if the system is a little older—so long as you’re not cranking up the dial on the ones you leave on. But some HVAC specialists argue that keeping your entire system on ensures that your boiler stays efficient. After all, it’s rated to fit your home and heats the amount of water your heating system needs. This could be the case if you have a new system. However, turning radiators off in unused rooms lowers the amount of hot water you need.

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.
