"Of course, my A/c failed on one of the hottest days in July. Frankie made it to my house in the afternoon the next day, not bad by any means knowing it is a busy time. Repair was quick as it was just the capacitor. Cost wise, a little high based on my neighbor that had same problem a few weeks ago. My bill was $450- (150 service call, 300 for capacitor) neighbors company charged $275 for same service. These capacitors only cost $20-30. Perhaps service tech was in a hurry and did not want to list the other categories such as diagnostic fee and repair labor and just added those costs to the part price."

"Cody arrived right on time to do the regular service of my gas furnace under the comfort program. He was especially well-informed on potential issues with the installation of my Carrier condensing furnace, including a notice from the manufacturer to make sure the condensate drain piping included a vent so the condensate wouldn't back up into the unit. Another firm had done the install before I found out about Shanco/Peppy. Cody added a vent to the piping in just a couple of minutes, so that potential problem is sorted!"

Boiler Repair questions, answered by experts

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.

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.

After you receive your audit and report, review the findings and determine which of the prescribed changes you want to make to improve your home’s energy efficiency. Start by contacting the type of professionals recommended by the auditor who can help you remedy the issues discovered during the audit. Prioritize the projects by urgency, importance, and budget. Then, gather estimates from several professionals, remembering to verify any necessary licensing and experience information.

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.

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.
