How to Tell When It’s Time to Replace Your Furnace

How to Tell When It's Time to Replace Your Furnace

 

We’re going to go out on a limb here and assume that you aren’t a member of the unlucky crowd that has to make a sudden decision on furnace replacement or installation. Wherever you are, we hope it’s not 12 degrees outside and your heater just died.

After all, a choice that will affect the next 20 years or so shouldn’t be made in an instant, right?

But knowing when to repair or replace that furnace can be an overwhelming and complicated decision to make. Having serviced ailing furnaces for over 100 years, we want to help clear things up for you. Below, we share all of the warning signs, failures, and considerations we’ve gathered over the years so you can decide if it’s time to replace your furnace once and for all.

6 Signs That You Should Replace Your Furnace

There’s no getting around the fact that virtually everyone will need to decide when to replace their furnace at some point in their lives. But, please, don’t wait until the last frozen minute.

If you’re asking yourself, “When should I replace my furnace?” we have you covered with all of the warning signs that show it’s time to invest in a new furnace installation:

1. Your Heat Pump is 10 Years or Older

Age has a destructive effect on everything from hips to heaters. According to the U.S. Environmental Protection Agency, if your heat pump (the unit that circulates the warm air) is inching up in years, you should start looking at furnace replacement and installation options.

2. Your Thermostat Seems Squirrely

If you’ve got the dancing thermostat syndrome (you program one temperature but get another), chances are it’s your furnace failing rather than the thermostat messing with your mind. Despite automatic settings, if your furnace is faulty, it can’t keep up with your heat demands.

3. The Age of Your Furnace is North of 15

The average lifespan of a brand-new furnace is 20 to 30 years. However, older models may only last 15 years. If your furnace is pushing 15 years old, it may be time to consider a replacement. Not sure how old your furnace is? Check for a pilot light as units that use them are often over 25 years old.

Not only are older furnaces nearing a breakdown, they are also probably only 60-70% efficient. This means that 30-40% of every dollar you spend on fuel disappears out the exhaust pipe or through the ductwork.

4. You’re Having Too Many Furnace Repair Visits

You might really enjoy chatting with your furnace repair expert, but if you have to pay for their company regularly, it may be a sign that your heating system is on the way out. If your furnace needs frequent repairs, start thinking about whether a replacement would be worth the investment when you add up your repair costs.

5. Your Furnace is Talking Trash

We actually believe the old adage “children should be seen and not heard” applies to furnaces (although “out of sight, out of mind” works perfectly, as well). When your unit starts making groaning, clicking, banging, or popping sounds, or your blower stays on incessantly, the end may be nigh. For detailed diagnosis, check out these eight common HVAC noises and what they mean.

6. The Family Feels Sluggish

Older furnaces can often suffer from cracks in the heat exchangers. This can lead to noxious fumes being circulated through your house, causing headaches, nausea, and general malaise. If your furnace is producing unhealthy fumes, air out your home and contact us immediately.

Four Common Causes of Furnace Failure

A faulty furnace isn’t just a cash burner, it’s also a potential source of serious injury to your family. Before you fire up your furnace, consider having a Minneapolis furnace repair expert come out to determine whether you need to invest in repair or a whole new install.
Here are the four causes of furnace failure you need to watch out for:

1. Heavy, Repetitive Furnace Cycling

Your furnace can be cycled on and off up to 10,000 times a year. After heavily repetitive cycling for at least a decade, your furnace will start to show its age. The best fix for an aging furnace is to consider purchasing a new furnace sooner rather than later.

2. Heat Exchanger Cracks

A gas furnace heat exchanger is heated by a blower fan from the furnace. The heat blowing over the warmed chamber funnels the heated air throughout the house, drawing the combustible elements out through the chimney. The process of heating and cooling causes the heat exchanger to expand and contract, often causing another reason for furnace failure: heat exchanger cracks—a problem that calls for immediate furnace repair. Arrange for an HVAC technician to inspect your heat exchanger and get your furnace back up and running.

3. Corrosion and Rust

The pilot flames in your furnace emit a powerful combination of carbon monoxide, nitrogen oxides, sulfur dioxides, and water vapors. This supply of moisture and acidic gases corrodes metal heat exchangers and causes rusting of welded parts, the third leading cause of furnace failure. This is yet another reason to consider installing a new furnace, especially if yours uses a pilot light, which can be a destructive, rust-causing element in older units.

4. Manufacturing and Installation Mistakes

Many manufacturing mistakes have resulted in massive recalls. For example, Carrier’s use of polymer (a plastic substance) when attaching fireboxes in the heat exchange system caused so many furnace failures the company paid $10 million to settle a class action lawsuit. However, furnace installation problems such as undersized ductwork, which causes more wear and tear from elevated temperatures, can also end a furnace’s life prematurely. Check to see if your furnace model was involved in any product recalls by contacting us.

Things to Consider Before Replacing Your Furnace

Life without a furnace in Minneapolis is unthinkable. No matter who you are, it’s important to have a functioning furnace to keep you warm and safe in the winter. But buying a new furnace is an expensive investment, so it’s important to be aware of all of your options.

Once you’ve decided you need a new furnace, here are six things you need to ask yourself before you start shopping for a furnace replacement:

1. Is Your Furnace Outside of Warranty?

Most furnaces come with a 10-year parts limited warranty. This means that if your furnace is more than 10 years old, it’s probably outside of warranty. Furnace manufacturers also offer extended warranties, so check your paperwork to see if your warranty is still valid. If your furnace is still within warranty, contact the dealer that you bought the furnace from. If the dealer that you bought the furnace from is no longer available, you can reach out to any local HVAC company that sells the brand of furnace that you own to find out which repairs are covered under your warranty.

2. Has a Professional Inspected Your Furnace?

Professionals who work with furnaces every day will have the best idea as to whether or not your furnace needs to be replaced. When you schedule a furnace installation visit with us, an experienced technician will visit your house, appraise your furnace, and let you know if it is worth buying a new one. They can also inspect your home in order to determine which type of furnace would be a good fit for your house. Keep in mind that if you walk into an appliance retailer and ask for furnace advice, the salesperson may simply encourage you to buy a new model since their job is to make sales, not to conduct repairs or home visits.

3. Gas or Electric Furnace?

The most popular type of residential furnace is a natural gas furnace. Natural gas furnaces cost between $2,500 and $10,000 to purchase and install. Natural gas furnaces are a popular choice because they are more energy efficient than oil and electric furnaces.

New electric furnaces have a smaller price range, usually running between $1,000 and $2,500 to purchase and install. However, the cost of running an electric furnace is typically more than running a gas heater, so keep your utility budget in mind before purchasing an electric furnace.

If you still aren’t sure which furnace you should buy, view our guide on how to choose between an electric or gas furnace.

4. Does Efficiency Matter?

Furnace efficiency will play a huge part in the total cost of your new furnace. While more efficient furnaces may cost a bit more up-front, installing a new, high-efficiency furnace cuts waste down to 5%, reducing your utility bills and providing you with a reliable heating source for years to come. In addition, you may be eligible for a federal tax credit, giving you an immediate return on your investment.

Look for furnaces with a high AFUE rating within your price range. AFUE is important to pay attention to because it is a measure of fuel efficiency. Energy Star suggests that people who live in the Northern United States should invest in a gas furnace with an AFUE of 95 or higher. Oil and electric heaters tend to have lower AFUE ratings because they are less energy efficient.

What BTU Rating Do I Want?

BTUs are a measure of heat output. Your location and the size of your home will determine what BTU rating you should look for. Consult a professional or use a BTU calculator to find an appropriate BTU rating for your home. The higher the BTU, the higher the cost of the furnace, so this measure will have an impact on the cost of your furnace.

What Is the Cost of Installation?

Installing a new furnace typically costs between $1,000 and $2,000. However, if extensive duct work is needed (say you bought a forced air furnace and your home doesn’t have air ducts) you will have to pay for ductwork as well, which can add thousands of dollars to your bill.

Think It’s Time to Replace Your Furnace?

Even though furnace replacement and new furnace installation are big investments, they are unfortunately inevitable. If you’ve seen any of the warning signs above, give us a call at 612-825-6867  or contact us for a free consultation or quote.

One comment on “How to Tell When It’s Time to Replace Your Furnace
  1. It’s great that you mentioned that efficiency plays a huge part when purchasing a new furnace. I would imagine that the size of your home can affect what kind of furnace you should get. If you have a large home, you aren’t going to want to get a furnace that is too small because that would get expensive.
