  • Furnace Installation and Replacement Services in NH

    Furnace Installation Services

    Heritage offers a variety of installation services when you need a new heating system. Our team continually educates itself on the latest systems on the market and what works best in different home layouts and situations.

    Depending on the age of your home, its layout, and what system enhancements you are interested in, we’ll make recommendations based on the best possible unit to install every time. From there, our team will work with you to provide a transparent estimate on the costs involved to get the job done.

    Gas Furnaces

    Gas furnaces are most commonly used in New Hampshire and Massachusetts because of their overall price. They are more efficient than oil furnaces and are usually less expensive to operate due to natural gas prices. Gas furnaces can emit more carbon monoxide than other types of furnaces if the fuel isn’t burning cleanly so it’s recommended to have a safety check performed once per year. Making sure you have a functional carbon monoxide detector and checking the batteries twice a year is another way to keep your family safe – with or without a gas furnace installed.

    Oil Furnaces

    Oil furnaces used to be the most popular choice for the Northeast United States. They can heat large areas of your home evenly and offer very little risk of carbon monoxide leakage in your home. They require an on-site oil storage tank to fuel your oil furnace, where you sign up for service to replenish your oil supply. Oil is often more expensive than natural gas and has a lower efficiency rating for heating your home. An oil system does provide more heating BTU’s per gallon than other heating sources, so while the fuel itself may not burn as efficiently, it generates more heat when it does.

  • Warning Signs That Indicate It’s Time for a New Furnace

    • Age Matters: If your furnace has been keeping you warm for over 15 years, it’s probably time to start considering a replacement. Most furnaces have a typical lifespan of about 15 to 20 years, provided they receive regular maintenance. If yours is getting up there in years, reach out to Heritage.
    • Rising Bills and Repairs: If your energy bills have been steadily climbing, and you find yourself calling for furnace repairs more frequently, it might be a sign that your aging furnace is working harder than it should. Older units, especially when not well-maintained, struggle to efficiently produce and distribute heat. This could be a good time to explore the idea of a new furnace.
    • Uneven Temperature in Rooms: Is one room in your home feeling like a sauna while another is an icebox? Older furnaces often have trouble evenly distributing heat, leading to inconsistent temperatures throughout your home. If you’re experiencing this issue, it’s a strong indication that it’s time to invest in a new furnace.
    • Soot or Rust Accumulation: The presence of soot or rust near your furnace register is a red flag. It suggests that your furnace isn’t functioning correctly and may even pose a danger to your home. Don’t wait—consider replacing your furnace immediately if you notice these signs.
    • Unwanted Noise: Furnaces should be like silent heroes, quietly keeping your home warm. When your furnace starts making excessive clanging and banging noises, it’s a clear signal that it’s time to think about replacing it.

    By recognizing these warning signs and acting promptly, you can ensure the safety and comfort of your home. If you have any questions about furnace installation or replacement, give us a call!

Gavin and Mohammed were exceptional in their customer service. Gavin explained my situation to me with excellence and his explanation was clear and well executed. I could tell he was well equipped with knowledge and was confident in his delivery of service which made me feel confident. Gavyn’s personaity made me feel comfortable and secure and was like a ball of sunshine on a cold rainy day.They both were gentlemen, professional and respectful. I’ve been living in my home for 34 years and have never been so impressed with the dynamic service that was provided to me by Gavin and Mohammed ( Haritage Home Service). The initial call process from Heritage was fast and well organized. My experience was nothing short of exceptional to the point where I never thought I’d be so excited to have new shiney, copper pipes! Don’t hesitate to call Heritage and change to them as your new home service company!
