Replacing Your Furnace: How to Know It's Time
When you have an old and failing furnace, the problem won’t go away on its own. In fact, rather than continuing to spend money on repairs for an inefficient heating system, replacing your furnace may be the most cost-effective way to proceed.
How Do You Know It’s Time?
Here are four signs your furnace is on its last legs:
- Energy bills are rising: If your energy costs are going up and you haven’t used your heating system more extensively, the furnace is a likely source of the problem. Regular maintenance may extend the usefulness of a furnace, but after 15 years it is unlikely that a system will be able to achieve the same results as in the past without consuming more energy.
- The furnace needs regular repairs: Old machines begin malfunctioning when they hit their useful life limit, which according to InterNACHI is between 15 and 25 years. Rather than continuing to spend money on repairs, look at what replacing your furnace would cost. If the next fix is a sizable fraction of a new furnace cost, it’s time to upgrade.
- Dust and humidity levels are unpleasant: Furnaces that have reached the end of their productive lives create high levels of dust and dry conditions indoors. It will be unpleasant for family members with allergies and create problems with your home’s interior. The same goes for high humidity levels. When your equipment cannot control these swings in air quality, the furnace is likely to blame.
- Hot and cold spots are everywhere: Another major problem pointing to the end of a furnace’s life is the shift in temperature from room to room. After repairing ductwork and sealing off air holes in your building’s exterior, there are no more excuses. Your furnace is going to top the list of suspects, especially if it is around 15 years old.
Searching for a New Furnace
Homeowners in Marietta and neighboring towns might be unsure which heating system is ideal for their home. For homes in the Southeast, variable speed furnaces running on natural gas may offer up to 95 percent efficiency. While natural gas furnaces are the most common type of heater in the region, they are not the only choice.
Heat pumps offer an alternative for homeowners looking to save energy. Able to provide up to four times the amount of energy they consume, heat pumps have lowered electricity costs for heating by as much as 40 percent. If you are thinking of replacing your air-conditioning system as well, heat pumps may be an all-around solution.
Rebates are available in many Atlanta suburbs if you are considering a heat pump as a way to conserve energy and replace a furnace. Ask Casteel HVAC professionals about the right fit for your home.
