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

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

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.

He was very knowledgeable and professional.I would have no problem recommending Top Flight to any of my neighbors.

Tyler from TopFlight was fantastic. He earned a new service subscription customer.A prior tech from Air Temp solutions left the previously working system disabled and not working. Their follow up tech quoted $1,250 for a new thermostat and thermostatic board. Needless to say I searched for another company.Tyler diagnosed a simple but easily overlooked problem. The system was restored with only a service call.Big call out to Tyler and Top Flight!

Isaiah was my technician who performed a routine AC checkup. He was professional, knowledgeable, and polite. I was impressed with the service so I signed up for the annual plan and have high expectations if I ever run into any issues. Top flight was recommended by a friend who had issues and used several companies that couldn’t fix the problem before finding Topflight that did fix the problem.

We had Top Flight install a new HVAC system. Isaiah and Tyler were great at the installation. They cleaned up after the job which was nice. The plus is the system is nice and quiet compared to our old system and the balancing they did reduced the temperature extremes in our upstairs vs downstairs.

Very professional and explained everything. I love the fact that they gave me different quotes and I did not feel like they were just trying to get money from me. Our house is only 4 years old and have had nothing but problems with the company that put the system in the house. I FINALLY have peace of mind knowing it was done right. I also really liked the yearly maintenance contract and it was not a crazy amout of money. Thank you for your trained technicians.

The other day, when temperatures were in the teens, I woke up to 54 degrees in my house. I went on line to look up HVAC services and saw that Top Flight had many excellent reviews. So I called them. A couple of hours later, Isaiah and Tyler came to my house. I have to say that it was one of the best experiences, if not the best, that I have ever had with a contractor or service person. They were here all day. Isaiah explained everything to me in detail and encouraged me to ask questions. He was so patient and so nice. Of course, they fixed the problem and gave me some good advice. He was very professional but easy going and well-informed. Also, the prices are very reasonable. I highly recommend this company.

We were going through a total nightmare trying to find a company to fix our HVAC system. We tried 3 different companies that took our money and left us with a system that would stop working within a month after they said it was fixed. Top flight found the problem the 1st time they looked at it. It's now been running for almost a year with no problems. Isiah and this company are the best. We highly recommend them. Thank you Top Flight.

As new customers with Top Flight, we were visited by Ryan for an initial system inspection and a review of the various customer programs that Top Flight offered.While Ryan's extensive experience and knowledge of our HVAC system were clearly evident, his ability to explain and demonstrate issues or items in normal, understandable ways impressed us the most as a new customer.Top Flight's office staff has been equally helpful. Christina, in particular, has been exceptionally helpful with all our new customer setups and arrangements.We highly recommend that Top Flight be included in anyone's short-list of an Honest and Polite Customer-Focused service from a well-established local firm.

Average. (I don't give extra stars to companies who demonstrate basic professionalism in being on time or having reasonable customer service). This company is VERY EXPENSIVE! They offer a discount to customers to "become members," which makes their service (which includes way more service than I want or need) appear cheaper by charging smaller monthly payments which add up to much more over a year than others charge for 2 annual maintenance checks. ($420/year for an 1800 sf house, compared to $180/year for the same sized house in Maryland.) This monthly payment plan makes it very difficult to track what service is already paid for and what is being prepaid. Thus they have pioneered a way to keep their hand in your wallet for months after the service has already been provided. No thanks. I don't buy it. They did allow me to cancel -which is apparently unusual for them- although they did not provide a refund for payments I made already for service that I won't get.

What can I say.....BEST HVAC COMPANY EVER! Since moving to this area I have be unable to find a company to actually listen to me and do proper work. Upon a recommendation from a friend I tried this company out and I was not disappointed. Ryan was extremely professional in diagnosing and fixing my issue. He made the whole process easy and as painless as possible. He gave me many options on new systems and even informed me on state and federal rebates in our area. Isaiah is an excellent technician who loves this work and really did an amazing job. He is also by far the most polite server provider I've ever had in my house period. Taylor rounded out this trio and made this an amazing experience. I'd recommend this company to anyone who doesn't want to be pressured by pushy sales people, "know it all" technicians, and "I know better than you" owners.

One of the only companies in the county you can trust to do a honest job in the hvac industry. I had three companies out to try and fix my issue and they either failed to diagnose it properly or lied and said it was an expensive repair in order to upsell a brand new unit. Isaiah quickly identified a bare wire shorting out against a copper pipe in the fan unit and fixed it charging me the proper amount for the service . He is a young smart and determined technician, but most of all he is honest.

In a nutshell, this company is fantastic!If you're still reading I'm going to elaborate on just why that is. We opened a new small business here in Lewes, DE and when we went seeking a local company to take care of our system they came highly recommended. Ryan reached out to me directly on Facebook to introduce himself and the team. Vey quickly he set me up with Taylor who got the ball rolling. She listened to what we were looking for and sent Mike out to have a look. He was professional and knowledgable in his diagnosis of our newly installed system. For no charge they told me what needed to be repaired and we set a day to do so. Mike and Josh came back (sooner than the appointment time I might add) and did a thorough job gettin our system up and running. Ryan and I talked again about the work and he gave us a very fair price.I am now a subscribing customer and intend to be so long as we are doing business here. I have nothing but great things to say about the entire experience and strongly recommend this team to any business in the state!
