FAQs

  • Boiler Repair Services in New Hampshire

    How Do Boilers Work?

    Many homes in the Northeast use forced hot water heating systems. Boiler is often used as a catch-all term to describe all sorts of heating systems, but what they all have in common is how they use water instead of air to heat your home, known as a forced hot water system.

    Forced hot water systems circulate water to different rooms in your house using baseboard radiant loops called “zones”. A thermostat in each room controls each zone, giving you control over the individual temperatures throughout the house. You may also hear someone refer to these types of systems as “burners,” though, that’s usually referring to just one piece of the system.

  • Common Boiler Repairs

    Typically, there are two main categories of boiler repairs depending on the issue and fuel type of your system: hydronic or ignition. Hydronic repairs involve leaks, a failed circulator pump or zone valve, a failed expansion tank, a failed air elimination device, or zone control issues. The most common repairs needed on the ignition side of repairs include a bad ignitor, a failure with the flame sensor, burner issues, or a failed gas valve.

  • Signs Your Boiler Needs Repairs

    For homeowners, it’s not always easy with a boiler to recognize something’s gone wrong unless the heat is out. Here are some signs to look out for indicating you need boiler repairs:

    • If the boiler turns on and off quickly, it could be short-cycling
    • Any water leaks around the boiler
    • Strange noises or sounds
    • Not enough heat coming from the baseboards, or it takes a long time to heat up to a comfortable temperature
    • No heat in one zone of your home

    If you notice anything unusual with your boiler, it’s usually a good time to call a licensed HVAC provider like Heritage Home Service to check it out.

    Our team will come to your home, diagnose any issues with your boiler, and provide recommendations and options on what to do next. We want you to understand what the issue is, how it impacts your home’s heating system, and what options are available so you can decide on what we do next for you and your home.

  • Does My Boiler Need Repairs, or Is It Time to Replace It?

    As part of presenting the options for boiler repairs, we may recommend replacing your boiler depending on the issue and its age. If there is a critical failure, such as a cracked boiler block, or it’s nearing its end of life, we’ll offer replacement as an option to consider. If your boiler requires a lot of costly repairs, investing in a new boiler is often the more economical option. Regardless, we’ll present every option at your disposal so that you can weigh the pros and cons of what to do with your boiler.

What Our Customers Are Saying

I’ve dealt with Heritage for many years because of their dependability. They are not the cheapest, for sure, but if you need a plumbing or HVAC system installed or serviced/repaired, there’s none better. I needed repairs to be done on slim duct covers that were damaged after having siding installed on my home. I called Heritage because they were the company that installed the original mini-split system in my house several years earlier. John Lindonen and another technician (unfortunately, I don’t remember his name) showed up as committed and did the repair work. They were very thorough, explaining every issue to me and answered all of my questions. They were polite, and extremely knowledgeable. I wouldn’t hesitate to recommend these guys to my family or friends.

The AI interactive was ok but screwed up my ph# so never got a call. However, Camile arrived and spent time discussing my points and activities performed, helped me tremendously and ultimately didn’t need service. He was professional, informative, and transparent so Heritage, please acknowledge his great service!

Derek Clark from Heritage Home Services did a fantastic job for us. He installed a new garbage disposal and fixed a leaky bathroom faucet quickly and efficiently. He was professional, knowledgeable, and pleasant to have in our home. He took the time to explain everything, completed the work with care, and left the area clean when he was finished. We really appreciated his friendly attitude and excellent service. We’d definitely recommend Derek and Heritage Home Services to anyone looking for a reliable plumber!

Nicholas Silva’s diagnosis is good and he has a good background, knowledge and experience in plumbing. It did not take much time for him to identify my problem. But, I think his company needs to be more reasonable and realistic in quoting.

Had Heritage replace my 87 year old fathers AC systems and they did a fabulous job. Dexter from the company was very easy to work with and they did the work in record time, since there was heat wave going on and my dad needed to be up and running fast. I would recommend them, they have a good history of superb customer service.

We contracted Heritage to clean mold buildup from our split AC system. We had Owen from the company visit our home for the service and he was very thorough and professional. He made sure everything was clean and functioning properly.

My central AC was not working, I made a call and 4 hours later Paul was here. He inspected a few things and was able to fix the issue. He was very knowledgeable, friendly, and respectful. If I need any service or repairs in the further I will be calling them again.
