"All three jobs went great. For the water heater replacement Lewis came to my house at a convenient time for me, removed the heater changed out the rotted pipes and installed a new one with warranty. The price was great too. This job was time sensitive and he made me a priority to get it done. For the bathroom tub drain unclog he was very professional and did a great job. My garbage disposal was leaking and I came home to a pool of water in my cabinet and on the floor. Lewis came out quickly to resolve the issue for me. He replaced everything under the sink and showed me what he was doing each step of the way. I think that he is a great plumber if you want to get quality work and learn about each job too."

Install Boiler questions, answered by experts

When winter rolls around, and you turn the heat on for the first time in a year, it’s normal to sense a light odor. This could smell a little like burning because some dust has gathered in the heating unit over the warm months and will fade away shortly after. However, there are some smells you should watch out for and take caution around: an egg-like sulfur smell or an electrical burn odor would indicate there’s something wrong. Turn it off and call a professional for maintenance as soon as possible. 

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out

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

On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.

Most propane boilers last 15 to 20 years with regular maintenance and proper care. The lifespan depends on the quality of the unit, proper installation, and the level of maintenance. Investing in annual service can maximize longevity and efficiency. Routine inspections and timely repairs prevent early breakdown, ensuring your boiler heats your home for years to come.
