"You will see in the picture that the tub faucets aren't level , the caulk didn't dry and it's still mushy and gross looking , switch on wall has a bunch of cardboard not sure why but looks like a fire hazard .the sink isn't level , he put clear caulk on the sink so when I painted the wall you can see the dark drywall . Major **** up. He told me he cut the carpet from under the toilet but NO he didn't. Around the switch plate the dry wall was ruined. I paid for drywall to be up but her never put up drywall tape or plaster . I was in a hurry because I needed to get to an appointment so I signed the without fully inspecting it . Sure wish I did . They more or less robbed this old couple of $16,000 .oh and the guy was pressuring us to let him stay longer to do more work . 10:00 pm I made him go . Instead of 1 day guarantee to finish he finishe so he says , on the second day . It still isn't complete. We got screwed. Oh . The sink is bigger than I wanted . "

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.

Most HVAC systems last between 10 and 20 years, with an average life span of 20 years. The individual components within an HVAC system have their own life expectancies as well. For instance, a furnace often lasts for 15 to 30 years, while a heat pump might need replacing after 10 to 15 years.

You’ll want to bleed your radiators at least once per year, typically in the fall before you plan to turn on the heat. Bleeding a radiator is a regular part of your heating system maintenance, and you’ll need to do this regularly to keep these units running efficiently. You should also bleed radiators any time they start making noise, like gurgling, hissing, or banging.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.
