FAQs

  • Does Your Heating System Need Annual Maintenance?

    Yes! We can’t stress this enough. Every home needs its heating system inspected at least once a year, either before or after the heating season. In fact, it’s often required by your system’s manufacturer to maintain your warranty. It allows providers like Heritage to identify potential issues, make recommendations for repairs or replacement if you need it, and ensure your system is running at peak efficiency before the start of the next season. It is often said in our industry that 90% of heating issues occur during the first few hours the system is turned on after a period of unuse.

  • Advantages of Annual Heating Maintenance

    Maintaining your heating system is crucial, and when you schedule professional maintenance with Heritage’s specialists, you’ll enjoy these benefits:

    • Potential energy savings and reduced heating costs
    • Improved heating system performance
    • Reduced need for repairs and replacements
    • Enhanced home comfort
  • What to Expect During a Heating System Maintenance

    Depending on the type of heating system you have installed in your home, regular heating maintenance services may include anything from replacing air filters to checking for carbon monoxide leaks or lubricating fan motors. Regular heating maintenance can also help ensure better indoor air quality by keeping dust and dirt particles out of the air.

    To get the best performance out of your heating system, make sure to schedule annual inspections with our qualified technicians. During heating maintenance, we’ll perform a thorough cleaning, test critical components, and check for any potential problems along the way.

    Whether you have a furnace or boiler, the time to schedule your heating system maintenance is well before the leaves start turning. If you have questions about these services, we’ll provide you with knowledgeable answers and guide you through the entire process. Contact Heritage today!

  • What Heating System Problems Do We See During Maintenance?

    Winters in New Hampshire can be rough on equipment. To give you an idea of what we uncover during routine heating maintenance, here are some common issues we find:

    Gas Furnaces
    From dirty air filters and blower wheels to failed ignitors or clogged condensate drains, Heritage knows what to look for to quickly diagnose issues with gas furnaces during annual maintenance. We’ll check common issues and correct anything causing your furnace to perform less efficiently, and we’ll even perform a camera inspection to detect more serious issues, such as a cracked heat exchanger. Finally, we’ll calibrate your combustion system using a digital combustion analyzer – something many technicians don’t use during maintenance because of how expensive they are to buy and maintain.

    Boilers
    Leaking fittings, failed air elimination devices or expansion tanks, and relief valve leaks are all common issues we see with boilers. Boilers’ long life expectancies mean they can see a lot of wear and tear over the years and it requires an experienced technician to keep older systems in check. Our trained team knows what to look for and how to make repairs to keep your boiler performing the way it’s needed each winter.

Oil Systems

Whether a furnace, boiler, or stand-alone hot water heater, oil systems tend to run “dirtier” due to the nature of the fuel being used. This makes routine annual maintenance especially important if you own an oil-fired system. One of the most common issues we find is sooted systems. This occurs simply from a lack of annual maintenance and cleanings. Soot build-up affects many areas of your boiler’s performance such as causing a cad cell sensor failure which will keep your system from turning on.

At Heritage, we always perform a deep clean of your system during each maintenance visit and check for common issues like worn electrodes, clogged oil nozzles, and more. And if you own a furnace, we’ll check your heat exchanger for signs of potential failure, a vital component to your safety that is often overlooked by other providers.
