"Santana Construction is absolutely the best around! Victor, Arturo and the rest of the team worked hard throughout the whole project to make the results even better than I could have ever imagined. What I wanted was a simple screen porch and patio area with a new fence, what I got was an immaculate screen porch with a spectacular patio and small built in seating area. Without a doubt I have the best backyard within miles! I would recommend Santana Construction to anyone that asks. They are thoughtful, respectful, offer options , they make sure they are always communicating with you and they take pride in every aspect of their work. Their work is of the best craftsmanship I have seen in years! I can’t wait to start my next project with Santana Construction! Thank you again Victor, Arturo and the rest of the Team!"

Boiler Repair questions, answered by experts

There are a couple of signs that will tell you it’s time to bleed the radiator. If the radiator is making noises, it’s typically because of trapped air, which you can release by bleeding the radiator. You can also test the radiator by turning on your heat and then placing your hand near the top and bottom of the radiator. If you feel cold spots, particularly at the top of the radiator, it’s time to bleed it.

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

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

If your radiator turns on every time you turn on your hot water, your problem is likely your motorized three-port valve that’s attached to your boiler. When it malfunctions, the valve isn’t closing properly, so the water begins to flow to your radiator, thus kicking off the heat. To fix this, hire a boiler repair tech near you to replace your valve.

To maintain a boiler and ensure it works optimally, regularly read the temperature and pressure gauges on the unit to ensure they're within the limits described in your owner's manual. Lubricate the circulating pump according to the manufacturer's instructions. Check the water level in the expansion tank and open the tank valve to drain it if it's more than half full.
