"Repair man was nice enough, but when he found (eventually) a bad outlet (not a bad disposal after all) under the sink where disposal was powered, the replacement fee was ridiculous. Nonetheless, I had to replace it, or the new disposal wouldn't have been replaced. Kinda felt a little trapped. Ended up paying too much and throw out a perfectly good yet older disposal."

"We had a great experience with Franklin Heating/Cooling and their employee Tony when they came to fix our AC. From start to finish, Tony was professional, efficient, and incredibly honest. It's not every day you come across a service company that doesn't try to upsell unnecessary repairs or replacements. They took the time to thoroughly assess the issue, explain what needed fixing, and offered a clear, fair solution. We really appreciated his transparency and how he genuinely prioritized our best interest over making a quick sale. It's rare to find companies that are this trustworthy, and I will definitely be using them for any future HVAC needs. Highly recommend!"

Boiler Repair questions, answered by experts

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

A poorly maintained boiler can lead to serious issues like deadly carbon monoxide poisoning, so schedule regular maintenance services. Of course, it’s also a good idea to check your carbon monoxide detectors in your home to make sure they’re working properly. Moreover, when you forget to maintain your boiler, small problems can lead to something much more serious, which will cost you more money in the long run. Repairs average around $400, while a full replacement can total over $6,000.

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.

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.

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.
