Knowing when to replace your furnace

Unfortunately, most people wait until their furnace is completely dead before replacing it. Many times, they will try to extend the life of the appliance by calling for repeated repairs. We certainly understand that thinking, but with our promotions and considering the amount you can save on utility costs, it’s usually cheaper in the long run to have an older malfunctioning system replaced.

A common question we receive from customers is how they are supposed to know when it’s time to replace their furnace. There are several signs, but the most common include:

  • AGE
    Furnaces can sometimes last more than 15 years if they are well-maintained. A unit that is around this age or older that is in need of constant repairs should be replaced
    Older, less efficient units will drive electric bills through the roof. We offer and recommend high efficiency furnaces and heat pumps for homes in our area.
    If you just can’t seem to get your home warm enough for your liking, it is possible your unit should be replaced
    We may have mentioned constant repairs on an older unit, but a furnace that is always in need of work, no matter the age, is costing you money

Benefits of installation from the professionals at Garrison & Garrison

No matter what type of heating device you choose for your home, it is always best to have it professionally installed. You may have an idea of how to implement the heating element in your home and may even be tempted to go to the hardware store to purchase the needed tools.

However, before you go to the trouble of doing so, consider these benefits of calling one of our technicians:

  • Safety
    Any work done with or to a heating device can potentially be dangerous because of the electricity involved and fuel that could leak. A full understanding of wiring and connection techniques are also needed to ensure your unit functions properly.
  • Lower Energy Costs–
    When a heater is installed professionally, it will warm your home efficiently. You can expect to be advised on how to best achieve optimal temperatures while still remaining comfortable.
  • Warranties –
    Any warranty that comes with a new furnace is likely invalid if installed by someone who is not certified. Why risk it?
