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.

When my AC quit suddenly, Heritage came in a timely fashion and did an excellent job. The four gentlemen who helped me were professional and knowledgeable. Joe diagnosed the problem and was very thorough in explaining the cost of repair versus replacement. Bobby, Harrison and the electrician Liam did the replacement and were wonderful to work with. They explained the process carefully, answered all my questions and completed the job efficiently and quickly. I would certainly call the company again for any HVAC, plumbing or electrical needs. Thanks Heritage!

First time using Heritage, as two other plumbers I’ve used in the past gave me long lead times. Heritage answered my call personally, and scheduled me same day-amazing considering it was a Saturday! I had a leaking outdoor spigot, and given the drought, waiting a week to fix it was out of the question. The technician sent out, James Shallow, could not have been more professional, knowledgeable and personable. He showed up on time, did the job seamlessly and without issue. He spent time educating us as to how to avoid this problem in the future, and it was a genuinely pleasant experience. I will most definitely use & recommend Heritage again (request Jimmy).

Alex came to fix a water main leak at my home which was pre-manufactured in the late eighties. He found and fixed the leak quickly. After the job was complete I spoke with him about the cause because this is the third time in a year with a leak. He spent the time with me explaining the material used for piping in my place and checked the water pressure. The pressure was on the high end and we both concluded between pressure spikes and old plastic pipes. I asked for an estimate to replace all the pipes. He was able to give me an estimate on the spot and found financing with very reasonable terms. Two days later Heritage Home Services was here with two trucks and completely changed out the piping in a day. In short. This place answers the phone. Gets technician on the job quickly. Great knowledge. Cleaned thoroughly before leaving.

We called several plumbers and I got “we are too busy” and “it’s too small of a job”. Not with heritage though! They were able to get us on the schedule in a timely manner and helped us with our plumbing issue. Thank you Zach! Zach was quick and professional! Will definitely use again!

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!
