6 Clear Signs You Need Boiler Repair

Schedule Now

Professional boiler repair in Cincinnati is generally called for whenever you notice changes in the system’s heating performance or energy efficiency, or see visual signs of component failure like leakage. Do you know who to call for boiler repair?

Boiler heating involves high temperatures, pressure and flammable natural gas. For safety reasons, options for do-it-yourself diagnosis are very limited. Making sure the system is turned on at the thermostat, set to the proper temperature and bleeding air out at individual radiators when needed is generally the only recommended recourse for the average homeowner. If boiler heating problems persist, call for professional boiler repair in Cincinnati.

Signs You Need Boiler Repair

Here’s a rundown of typical boiler symptoms that require the expertise of a qualified boiler technician so you can determine when and who to call for repairs:

  • No heat at all
  • Signs of water leakage
  • Unusual noises
  • Pilot won’t stay lit
  • Low water pressure
  • Radiators not fully heating

No heat at all

This could be caused by air in the system, failures of valves or circulation pump, loss of water level or thermostat issues.

Signs of water leakage

There are numerous potential sources of water leaking in a boiler system. Some are inexpensively resolved; others may mean major component failure.

Unusual noises

Generally speaking, a boiler system should operate silently. Rumbling, banging, whistling and gurgling sounds usually mean a problem somewhere, but it takes a trained boiler technician to determine exactly what and how serious it is. For example, build-up of mineral deposits in the boiler or air getting into the system are common causes of noisy operation.

Pilot light won’t stay lit

This could be a defective thermocouple shutting off the gas supply. It’s a safety issue that should only be addressed by a qualified professional, so find out who to call for boiler repair and take care of this problem right away.

Low water pressure

All boilers require a certain minimum water pressure. If pressure drops below that level, a safety cutoff switch will automatically turn off the boiler. Potential issues that cause low pressure range from leaks to air in the system to problems in the expansion tank.

Radiators not fully heating

Air in the system due to a number of possible causes and/or sludge build-up could be responsible. A full system bleed, as well as chemical flushing, may be required.

DIY Boiler Troubleshooting Tips

Before you decide who to call for boiler repair, there are some quick and easy troubleshooting steps to try first. These steps help correct simple issues that you don’t want to pay a technician to solve for you if you are able to avoid it.

It’s a No-Brainer, But…

Check the thermostat first. Make sure the heating system is turned on and the desired temperature setting is at least five degrees above current room temperature.

Any Signs of Life?

If your boiler has a controller and an LCD display screen, check to see that the screen is lit and receiving power. If it’s not, you may have an electrical failure or a defective circuit board in the controller. If the screen is lit, check for any fault codes or error messages that may be displayed. Write them down and pass them on to the HVAC contractor when you call. If the display screen and other indicator lights are dark, go to the electrical panel and look for any tripped circuit breakers. If you find one, reset it and check the boiler again.

Check the Gas and Pilot Light

At the boiler, the main gas valve should be in the “open” position. If it’s not, call your HVAC contractor and inquire why. If work was recently performed, it may have been inadvertently left closed. Verify the reason before you turn on the gas.

If the system incorporates a standing pilot light, see if it’s lit. If not, follow manufacturer’s re-lighting instructions. Frequently, a defective thermocouple will extinguish the pilot and prevent re-lighting. In that case, you’ll need professional help.

Newer boilers utilize electronic hot surface ignitors instead of standing pilot lights. Usually, there’s a conspicuous reset button you can try to revive an electronic ignitor. If you have no luck resetting, your HVAC contractor can handle it.

If these tips are unable to resolve your system issues, know who to call for boiler repair to restore heat in your home fast.

Should I Retrofit My Boiler?

If your old boiler isn’t keeping your home warm, experiencing frequent breakdowns, or resulting in higher energy bills, retrofitting may be an option for you. A retrofit allows for improvements in performance, energy efficiency, and safety for your current boiler system without a full replacement.

As you consider who to call for boiler repair, be sure to ask about retrofit options. Common retrofits that improve existing boiler systems include:

  • Programmable or smart thermostat installation
  • Zoning system installation
  • New high efficiency burners
  • Modulating aquastats
  • Time-delay relay

During a retrofit, new technology is added to enhance your existing system and deliver the improvements mentioned about. These projects have a lower price than a full replacement yet still generate significant savings.

Ready to Replace Your Boiler?

If you are ready to trade your underperforming boiler for a new, high efficiency system, who to call for boiler repair is also an option for boiler replacement! Especially in older homes, aging boilers may be patched up over the years with retrofits and repairs, but they just don’t deliver the efficiency and performance that an entirely new boiler system does.

When you evaluate the decision to replace your boiler, consider the following:

  • How old is your boiler? Newer modulating boilers last on average 15 years or more, while older cast iron models last 20-30 years. These estimates are often improved with good maintenance, but if your boiler is near or at that age, it’s time to look into replacement options.
  • How high are your energy bills? Boilers lose efficiency as time goes on which raises your energy bills. With an older boiler in place, you are likely paying significantly more than you would with a new system.
  • How often do you need repairs? More repairs mean more expenses. Consider if those funds would be better invested into a new system that helps you save money rather than for patching up your old unit.

Ductless Offers a Heating and Cooling Alternative

Owners of older homes that originally had boiler systems often believe that’s the only option, because there is no ductwork installed in the home. Luckily, modern technology has provided an alternative – ductless heating (and cooling!).

If you’re looking for who to call for boiler repair but are considering replacement as well, ask about your options with ductless heating and cooling. These systems are installed with minimal intrusion regarding your home’s historic look and feel. They’re highly efficient, low maintenance, and offer the advantages of zoned comfort.

"Ernie & Mike did a superb job on my new furnace and A/C installation. Despite having more than a day’s work to do, they came in and stayed until the job was done. They were organized, efficient, and protected the rest of the house well. Got both furnace and A/C installed the same day. Ernie was courteous, informative, and clearly knew his job better than anyone I’ve encountered before. The units look so good guests now get The Tour of our new system. Apollo is clearly not a fly-by-night company. I would recommend them to anyone in need of a new furnace and/or A/C."
- Jerry A.
"I called Apollo because of a water leak I thought I had in our upstairs shower going into the kitchen. Robbie came and assured me everything was fine & looked at all the other plumbing. He ended up changing a few pipes for our washer & clearing a drain. He was very nice & knowledgeable with all my questions. I ended up signing up for the care plan & was very happy with my service."
- Cassandra B.
"The team at Apollo exceeded my expectations. As a business owner, my attention to the details and commitment to providing excellent service is high. From the sales rep. to the installation team, everyone’s performance was outstanding. For example, the installation team went to great lengths to protect our floors, placing floor runners and across the wood floors and up the stairs. They even were spot washing walls upon their departure. I highly recommend this company."
- Randy B.
"We scheduled an estimate AND a tune-up. We knew something was wrong with our furnace, but hoped we could make it through the rest of the season. Upon telling Bill what our furnace was doing, he warned us immediately what the possible outcome was going to be; a cracked heat exchanger. He watched the flames roll backward, tested carbon monoxide levels, which were so high they meter’s last reading was 5,600 before saying “high”. He immediately shut it down, tagged it, and explained that with levels that high and children in our home he wanted off right away. He continued his inspection and showed us via a camera that not only was it cracked in multiple places, but had holes all over it. He gave us a few options for repairing it; his knowledge as well as genuine concern was beneficial and refreshing. Luckily we also scheduled an estimator, Micah, to come too and we were able to get costs between repairing and replacing (with several options). We decided to replace with a much higher efficiency furnace and one sized properly to our home. Hands down, not only did they both provide us great service and knowledge, but without sounding dramatic, they may have saved our lives. This was our first time calling Apollo, but it won’t be our last."
- Sarah B.
"Apollo is an excellent company. I always receive great service. Alex A. was professional and friendly. He kept me informed during the process of checking my furnace and heat pump to make sure they were working properly. The company makes sure you are notified who is coming and when they are on the way. All my interactions with the company have been wonderful."
