What causes boiler problems?

Several factors can lead to your boiler breaking down or losing efficiency. Contact us for an accurate diagnosis and solution to your particular problem.

Take a look at common boiler problems we can help you solve:

  • Lack of hot water or heat: If you fail to receive hot water, the boiler’s diaphragm is likely broken and no longer functioning. The motorized valves in the boiler may also have stopped working correctly, or the thermostat is not properly registering the temperature.
  • Leaking: This problem is caused by a loose seal in the boiler or a puncture in the diaphragm.
  • Unusual sounds: If your boiler is producing strange noises, such as loud clanking sounds, there is excess air in the system. Strange noises may also indicate low water pressure.
  • Pilot light fails to stay lit: There are various reasons why your gas boiler’s pilot light has gone out. The thermostat may be broken or incorrectly set, impeding the supply of gas. There may also be a draft that is blowing out the light before it can be properly utilized. Another issue involves a deposit in the pilot light that is preventing the gas from reaching it.
  • Lack of pressure: A drop in your boiler’s water pressure is a sign of leaking. We will track down the leak and inspect your boiler to make sure further problems do not develop.
  • Kettling: If you hear kettling or rattling noises, there is likely mineral buildup in your system due to hard water.

Yes. Your boiler should be professionally maintained at least once a year. If you have an oil-fired boiler, a burner service should be performed annually by our oil delivery company.

Boilers are designed to last an average of 15 years. High-quality boilers will last longer with routine maintenance.

What are common radiator problems?

Below are problems to look out for in your radiators. If you notice any of these issues or other problems, contact us for immediate service.

  • Trapped air: You can tell if your system has trapped air if the lower half of the radiator is hot while the top half feels cool. To solve the issue, we will bleed the regulator, then inspect it to see if there are any other underlying problems.
  • Sludge buildup: If your system has cold patches at the top, there could be sludge building up. There could also be rust or sludge blocking the proper flow of water. Our experts will flush out the system to clear it out.
  • Loud noises: If your home uses a boiler to supply heat to your radiators, you may hear unusual sounds. This is often due to the boiler overheating. This happens if the temperature is set too high, or if there is limescale buildup in the boiler.

How can you tell if there is a problem?

Be on the lookout for these signs that your radiators are failing:

  • Leaking
  • Rust on the radiators
  • Loud clanging sounds from the pipes
  • Unexpectedly high temperatures, or abnormal temperature fluctuations

Have a burst pipe emergency?

Burst pipes can cause significant water damage in a short period of time. They often occur during the winter, when pipes are likely to freeze. Frozen water expands inside the pipe, and the constant expansion and contraction can be too much for the pipes, causing them to burst.

Contact us immediately if you notice a burst pipe so you can avoid the following problems:

  • Electrocution: If the water inside your walls reaches any electrical outlets, wires, or your electrical box, there is a risk of electrocution.
  • Water damage: Burst pipes can lead to water leaking throughout your home, causing severe damage to the walls and ceilings.
  • Costly bills: Along with damaging your property, a burst pipe can also spike up your water bill. This is especially true with minor pipe bursts, which can go unnoticed for some time.
  • Mold: Due to the amount of moisture created from a burst pipe, mold can begin to form. This can cause further health problems.

Call us immediately if you notice any signs that a burst pipe has occurred. We will repair or replace your pipes and prevent as much water damage as possible.

How can sump pumps prevent unexpected problems?

Sump pumps can help prevent flooding in your home. They are installed in the lowest area of a basement or crawl space and use drains to make sure water travels away from your home.

We can install a new sump pump for you to keep your home safe during heavy rains, or we can repair your existing unit. A sump pump helps prevent water damage caused by flooding, so make sure you have one installed to keep your home dry.

How can you prevent clogged toilet emergencies?

Severe toilet clogs can lead your unit to overflow. To prevent this problem, be mindful of what gets flushed on a regular basis. Avoid flushing excess toilet paper and other items that are difficult to break down.

If there is a clog farther in your sewer line, we will need to remove it before it causes your drains and toilet to overflow. If regular drain cleaning methods are not enough, we will discuss hydrojetting options with you to make sure your sewer line returns to normal as quickly as possible.

No matter what plumbing emergency you are facing, call on the experts who guarantee top quality care. Contact us at (917) 602-6665 for immediate service.

Older HVAC systems that are not creating an even and desirable temperature throughout your home will typically need to be replaced, especially if you notice a steady increase in your monthly utility bills, which likely means that your unit is losing efficiency and attempting to work harder to cool or heat your home. Additionally, a major repair that exceeds 50% of the cost of a new HVAC unit will be better remedied by replacing the system altogether, this is also the case if you are faced with a seemingly endless string or repairs and your bills continue to rise without a permanent solution in sight.

What are some benefits to installing a new system?

Want maximum control over your indoor climate without any foreseeable repairs in the near future? Then it is about time to have a new HVAC system installed. Newer units are not only better for the environment, but they are also far more efficient, which will help to significantly lower your monthly energy costs. Plus, your old system has collected years of dust and other allergens that can be dispersed throughout your home, lowering indoor air quality. This will not just make for an untidy home, but it can also create a number of health risks for you and your family. Newer HVAC systems are also built to last longer, are smaller and simpler to install, and function very quietly making your time at home more enjoyable. The knowledgeable staff at Heidler, Inc. can go over several different options with you and help you to choose the right system tailored to your budget and specific needs.

What can you do to avoid clogs?

Although minor clogs are common due to small debris and mineral buildup over time, you can avoid major clogs by being mindful of what enters your kitchen and bath drains on a regular basis.

Food waste should only go down a drain with a garbage disposal installed. Garbage disposals should be run with cold water for at least 30 seconds. Grease and difficult to shred food items (coffee grounds, bones, fibrous vegetables, etc.) should not enter your drains.

Make sure you have a strainer over your drain to catch stray food particles and limit clogging. A strainer should also be placed over your shower drain to catch hair and soap. This is a simple yet effective way to prevent buildup in your pipes.

  • Standing water
  • Reduced flow through drains
  • Foul odors coming from the drains
  • Water backing up through drains and fixtures

How can you tell if you have a hidden water leak?

Some leaks are easy to notice. Others may stay hidden for weeks or months before the damage has been realized. If you notice the following signs, contact us for immediate inspection:

  • Discolored or bulging drywall and ceilings
  • Standing water or moisture near pipes and fixtures

If you are experiencing these problems, our technicians will assess your plumbing system and identify any risk factors that could be creating the leak.

Do you suspect a slab leak on your property?

Leaks that occur beneath concealed pipes and plumbing are difficult to detect. Keep an eye out for these signs that point to a slab leak:

  • Decreased water pressure
  • Sudden spike in your water bill
  • Sound of running water between the walls
  • Moisture or mold beneath your carpet
  • Cracks in walls or baseboards
  • Hot spots on the floor (from a leaking hot water line)
  • Cracked tiles or bubbling linoleum floors
  • The dial on your water meter continues to move even though you are not using any water

While these are strong indicators of a slab leak, a professional assessment is the most accurate way to identify and diagnose a slab leak on your property.

If left untreated, a slab leak will damage your building’s foundation or lead to mold and mildew growth. Even a small pinhole leak can waste over 10,000 gallons of water in a month.
