Why Is My Boiler Making Strange Sounds?

Your home’s boiler requires maintenance for efficient and safe operation throughout the winter. Even when you do follow a consistent maintenance plan, some problems can still occur. Often, the first sign of a boiler problem is an unusual sound. Take a look at why your boiler may be making these common sounds.

Whistling or Kettling

The whistling sound you might hear coming from your boiler is also referred to as kettling because it resembles the sound of a teapot’s whistle.

While boiler winter maintenance tips in Indianapolis, IN, can help you prevent other problems, this condition may be beyond your control. It usually results from the sediment buildup that hard water causes.

The heavier mineral content in hard water can lead to corrosion on the inner walls of the pipes in your boiler. As the buildup slows the flow of water, the water heats faster and begins to boil. The result is the whistling noise you hear. Ask your HVAC technician to clean the system and restore proper water flow.

Gurgling Sounds

A boiler that produces gurgling sounds isn’t necessarily a serious issue, but it’s important to address the problem before it worsens. The gurgling noises result when air gets into the system and mixes with the water. A simple fix is to pour warm water over the condensation pipe. As the pipe thaws, the issue should resolve itself.

If you still hear gurgling sounds, you may need a technician to bleed the system. This service involves flushing out the water that contains pockets of air.

Vibrating or Humming

Vibrating pipes or humming sounds are more common with a system that uses a heat pump. If the installer sets the heat pump too high, heated water can get pushed too fast through the pipes. This leads to the vibration noises the system is producing.

Alternatively, a system that doesn’t use a heat pump can still produce a humming sound. Over time, sludge will build up within the pipes, slowing water flow and causing the system to overheat. That is why one of the best boiler winter maintenance tips in Indianapolis, IN, for preventing this problem is to schedule an annual tune-up.

What Is an Inverter-Type Air Conditioner?

What Is an Inverter-Type Air Conditioner? Homeowners have many new energy-efficient options for home climate control, but there is still a lot of confusion about how they operate and what the benefits are. Here’s everything you need to know about inverter air conditioning units in Indianapolis. About Inverter Air Conditioning Inverter air conditioning is technology specifically designed to help you save money on cooling costs by optimizing the HVAC system. Inverter-type air conditioners differ from other types that typically have the motor turned on or off; instead, they adjust the temperature by changing the motor speed without shutting it off. This leads to less power loss overall, making it an excellent choice for the energy-conscious homeowner. Inverter Air Conditioning Benefits Why should you consider inverter air conditioning units in Indianapolis? There are plenty of fantastic benefits to switching to this type of HVAC. Here are just a few. Energy efficiency is the number one reason homeowners choose this kind of AC. It offers the perfect combination of eco-friendly and cost-effective, two factors that are becoming more popular with consumers every day. Inverter air conditioners also offer more consistent, accurate cooling technology. The motor in traditional units only has the on/off option — this can mean that the AC might have a more challenging time getting into or out of certain temperature thresholds. But inverter-type air conditioners won’t have that issue, so you’ll have a more comfortable home regardless of your preferred temperature. Because inverter air conditioning units are newer, they’re also made from high-quality, durable materials. Many homeowners are stuck in the past with old, less efficient units that are already on their way out. However, when you invest in an inverter air conditioning system, you’ll have an excellent replacement for your older system — one you can trust to last you for years.
