Do You Need a Furnace Replacement?

If well-maintained, a furnace can last 15 to 20 years. But if you notice any of the following signs, it is time to consider replacing the system:

  • An unexplainable increase in energy bills.
  • More dust, dander, dirt, soot, or rusty residue when the furnace is on.
  • Some rooms may be a different temperature than others, or not getting heat at all.
  • There’s more humidity in your home than usual.
  • The furnace hums, rattles, buzzes, and is otherwise noisy.
  • You notice a strong fuel odor around the unit.
  • There are visible cracks or signs of rust on the furnace.
  • You need to repair your heating system frequently.
  • The furnace is hesitant to start or restart.

Heater Installation FAQ’s

Here are some of the most common questions we receive from customers:

How Long Does It Take to Replace a Furnace?

We can usually complete furnace replacement in one day, unless you require additional ductwork or venting to be installed. Installing a different type of furnace than the old one can require a few more days of work.

How Do I Know When to Install a New Furnace?

If your unit frequently breaks down and is over 15 years old, replacement is the best option. With new heater installation, you can avoid additional repair costs that can be as much as purchasing a new system.

What Sized Heater Do I Need?

Heaters come in a range of sizes. Our heating professionals can perform a heating load calculation test to determine how your existing system is performing. Using the data they collect, it’s possible to choose a furnace that’s most efficient for your home or business.

What Temperature Setting Is Best for My Heater?

Around 120° is a comfortable setting for most, and manufacturers often pre-set new water heaters to this temperature. Older water heaters should be set to medium.

Why Does Hot Water Keep Running Out?

Over time, you come to expect hot water every time. If the hot water is running out faster than before, your water heater may have a failed heating element or broken dip tube. Depending on various factors, you may consider repairing or replacing the system.

If It’s Leaking, Do I Need a New Water Heater?

Heaters can leak for a variety of reasons. Loose pipe fittings can be tightened or replaced. Other leaks can be patched or repaired. However, if the internal tank is cracked or there is other major damage, we’ll suggest installing a new water heater.

How Do I Know How Efficient a New Heater Is?

Furnaces are rated by their annual fuel utilization efficiency, or AFUE. High-efficiency models have an AFUE of 90 or higher.

Should I Install a New Heater and AC Together?

That’s a good idea because both systems are probably reaching the end of their life expectancy. Mixing equipment can cause some components to work harder than others. Since heating and cooling systems use some of the same equipment, a complete overhaul is most practical.

Is Professional Installation Necessary?

Don’t try to replace a furnace or heater yourself. Always leave the job to a professional. They’re trained to use specialized tools and follow procedures that avoid equipment damage and injury.
