I am a Journeyman Union Carpenter by trade but after 15 years left it to pursue other things. I have had rental properties and done hundreds of property rehabs and remodels over the years. I have a working knowledge of plumbing and electrical and I take pride in my work. I also rehab and refinish antique wood furniture and build custom furniture out of old wood and recycled materials. No job is too small and I enjoy meeting all the people that this kind of work leads me too.

Boiler Repair questions, answered by experts

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.

Some of the signs of HVAC issues include rising energy bills, rooms not cooling or heating properly, loud noises when in operation, and signs of condensation. To illustrate, if you’re wondering how to stop condensation on air vents, you’ll need to have your HVAC inspected. 

Boiler leaks are the most common problem that impacts this fixture. Some leaks stem from corroded pipes and tanks, while others are due to damaged seals or excessive pressure. No matter how you slice it, boiler leaks are bad news. This issue leads to water damage in the home and malfunctioning electrical components in and around the boiler.

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.

If your home uses more than one gas appliance, you'll continue to use gas, even outside of the heating season. Your water heater, gas stove and oven, and gas dryer will all use some gas, although typically much less than a furnace. Additionally, those appliances may also have a pilot light that is lit continually, using a small amount even when no one is at home.
