Common Signs Your Boiler Has a Problem

A hot water boiler needs professional attention when it’s malfunctioning. Due to the heat and gas involved, we do not recommend DIY for any issue your boiler is experiencing. Here are some of the signs that your boiler needs repair:

  • The smell of rotten eggs indicates a gas leak. In this case, you should shut off your gas, extinguish any candles, open the windows, contact your gas company, and evacuate.
  • The pilot light is supposed to be blue. If it’s any color other than blue, your boiler has a problem.
  • Unusual noises from your boiler indicate a buildup of pressure in the system.
  • If your boiler shuts off on its own, it might mean a blockage is preventing water flow.
  • If your boiler is not producing heat, the problem could be anything from a malfunctioning thermostat to internal damage.
  • If your boiler leaks water, a seal or valve has gone bad. If left unchecked, a leak in your boiler can harm the entire appliance.
  • Fluctuating temperatures in your boiler indicate a buildup of air that needs to be released.

If you notice any of these issues, call our Top Flight team right away for prompt boiler repair.

Understanding How Your Boiler Works

Boilers may have a lot of parts, but the way they heat your home is simple. Gas releases into a combustion chamber where it heats water in your boiler to pump toward the radiators, heating your home. Boilers are simple, with relatively few components, so identifying a problem is a quick process for a professional boiler technician.

Boiler Repair Checklist

Boiler problems can leave you with no access to heat. Understanding the problem is vital to getting your boiler up and running again quickly. When we arrive for your repair appointment, our technicians will perform several tests to diagnose the problem:

  • Check the water pressure. If it’s low, you could have a leak.
  • Check the radiators. If the radiators aren’t hot, there could be an issue with the boiler pump or heating controls.
  • Check the gas pressure. If the pressure is too high, it could lead to leaks. The boiler won’t operate efficiently if the gas pressure is too low.
  • Clear the buildup of debris in the chimney and burners so the boiler can run more efficiently.

Residential and Commercial Boiler Repair

Boilers heat both residential homes and commercial buildings. Our Top Flight Heating & Air technicians offer the best boiler repair in Milton, DE, because we understand the difference. Whether it’s your home or place of business, we’ll find the best solution that works for you.

Residential Boiler Repair in Milton, DE

We understand that time is of the essence for residential boiler repairs. Delaware winters are cold, and a faulty boiler is a significant concern for your home. We will work with you to get your boiler’s parts and repairs as quickly as possible.

Commercial Boiler Repair in Milton, DE

Boilers in commercial buildings tend to be older. Unfortunately, some older boilers have reached an age when repairs aren’t feasible, and a replacement is necessary. We’ll work with you to get the most efficient unit to save money on electric bills in the long run. Your boiler system is an intricate piece of equipment that requires specialized knowledge and tools for proper maintenance and repair. It’s not just about fixing a leak or replacing a broken part. It’s about understanding the whole system, from the gas boiler that heats your home to the air conditioning that cools it down.

Don’t Risk a DIY Disaster-Trust the Pros!

Your boiler system is not just a simple piece of equipment; it’s an intricate assembly that involves gas boilers, heating systems, and sometimes even air conditioning units. Handling such complex systems requires a high level of expertise and knowledge. This is where our professional technicians come into the picture. They are highly trained and certified individuals who understand the ins and outs of boiler maintenance and repair.

DIY repairs might seem tempting, especially when considering costs. However, your home’s boiler is a sophisticated device, and without proper training, you could inadvertently cause more harm than good. An incorrectly repaired boiler may not only function inefficiently, leading to higher energy bills, but it could also pose serious safety risks. Natural gas, which powers most boilers, is highly flammable, and mishandling can lead to dangerous leaks or even explosions.

Choosing professional boiler repair over DIY is not just about getting the job done. It’s about ensuring your system’s safety, efficiency, and longevity. As the boiler experts at Top Flight Heating & Air, we are committed to delivering high-quality boiler service every time.

So, the next time you face issues with your boiler, don’t reach for your toolbox; instead, contact us at Top Flight Heating & Air. We’ll take care of your boiler so you can enjoy a warm, comfortable home all year long.

When to Consider Boiler Replacement and the Benefits

We’ll always attempt to repair your boiler first, but a replacement boiler may be necessary. Older boilers, in particular, are prone to the sorts of issues that require replacement instead of constant repairs.

It might be time to replace your boiler:

  • If your electric bill is starting to climb, an inefficient boiler may be to blame. Your boiler is responsible for around 60% of your monthly energy bill. Boilers get less efficient as they age, and a newer model can save you a lot of money each month.
  • If you’ve noticed your boiler is getting louder, it’s another symptom of an aging boiler that needs replacement. Modern boilers operate quietly.
  • If you’re short on storage space in your home, we can install a smaller, more efficient modern boiler to replace your old, clunky boiler.

The Benefits of Routine Boiler Maintenance

Regular inspections for your boiler can extend its lifespan. Catching minor issues before they become significant problems goes a long way toward keeping your boiler alive longer.

When you invest in routine maintenance, you won’t find yourself suddenly without heat at the worst time. Your boiler malfunctioning during winter is a major hassle, and regular checkups are great preventative measures.

A routine inspection that discovers no issues is also much cheaper than overdue repairs. You’ll also have advanced notice if your current boiler is reaching the end of its lifespan if you schedule regular checkups. Our technicians can recommend when you should consider replacing your boiler before you suddenly find yourself without one.

Response from the owner:We're thrilled to hear you had a positive experience with our timely service and friendly employees. Thank you for your feedback!
I’m sure that a lot of HVAC Companies are similar to Top Flight. I called them and ask the to come out on a weekend because I didn’t have heat. While they were on their way I figured out that I had a bad contactor. When the guy arrived, I showed him the contactor. He didn’t have one in his van. So he had to go get one. He replaced it and checked over the rest of the system and say I was low on refrigerant. He came back two days later and added 1/4 lb of refrigerant. I paid $1,488 for them to replace 1 contactor and a 1/4 lb of refrigerant. I was totally RIPPED OFF. I definitely would not recommend them!
