Commonly Asked Questions About Furnace Replacements

Everyone wants to feel comfortable at home.  Your heating system plays a vital role in creating a comfortable environment in your home. However, if your system isn’t operating efficiently, it may be time to consider replacing/upgrading your furnace.

Here are the most frequently asked questions about replacing your furnace.

What Type of Furnace Issues Can I Fix On My Own?

The simple answer is none. Furnaces are complex and expensive. We do not recommend attempting to repair it on your own, this could potentially cause more damage..

With that being said, here are several simple troubleshooting steps you can try before calling a HVAC professional.

  • Check the batteries in your thermostat
  • Replace any filters
  • Check the electrical panel to make sure the fuse is not blown, or the breaker is not tripped
  • Check the on/off switches to be sure they were not accidentally turned off

When Should I Call An HVAC Professional for Repairs?

Call an HVAC professional if you have tried the troubleshooting tips mentioned above and your furnace still needs to be fixed.

HVAC technicians undergo years of education and training. They are also required to obtain licenses to provide their services legally. We recommend that you always take advantage of their training and knowledge to tackle all of your HVAC repairs. This will ensure that your problem is diagnosed and fixed quickly, effectively, and safely.

When Do I Need to Replace My Furnace?

If your furnace is not heating your home, it may be possible that an HVAC company can repair the issue. Unfortunately, this is not always the case, and  it may be time to replace your furnace.

Here are possible indicators that your furnace is ready to be replaced:

  • Between 10 to 15  years old
  • Requires frequent repairs
  • No longer keeps your home comfortable
  • Energy bills continue to increase
  • Emits unusual smells
  • Makes loud or odd noises
  • Dust increases in your home

If you notice one or more of these, please schedule an appointment with an HVAC technician.

How Much Does a New Furnace Cost?

This is one of the most frequently asked questions regarding replacing a furnace.  . With most people, the cost is a deciding factor.

Unfortunately, there is not an exact answer as there are many variables that have to be taken into account when looking at purchasing a new furnace. . Factors that need to be considered are the type of unit you want, the size of the unit you need, and other accessories you may want to add.

We recommend that you work with your HVAC company to explore your options. They can explain the financial details on the unit that best fits your needs. . They can also let you know what financing options they offer. Keep in mind that the cost of a new furnace includes the labor, testing, and adjustments needed to ensure your unit is properly installed and functioning.

What Size Furnace Should I Buy?

This is an important question to consider once you decide to purchase a new furnace. You do not want to buy a unit that is too small, as it will not properly heat your home.. You also do not want a unit that is too big, as it will use more energy than is needed.

Instead, you want a furnace that fits into the Goldilocks zone—one that is just right for your home..

To make sure you buy the right unit for your home, your HVAC company should perform a Manual J calculation that measures the following variables:

  • Square feet
  • Ductwork
  • Number of windows
  • Type of windows
  • Insulation (grade and quantity)
  • Climate

After the calculation, they can let you know the correct size needed .

How Long Will the HVAC Installation Take?

This will depend on what you are having installed. If you are only replacing the furnace,  the installation will typically take one day.

The installation can take several days if you are replacing your entire HVAC system—including the furnace, AC,  and ductwork.

Should I Replace My Ductwork?

We recommend that you have your ductwork assessed as part of your HVAC replacement bid. If your current ductwork is old, it might not be properly sealed or insulated. It may also be too small or have other restrictions, limiting airflow.

Your HVAC company will be able to review the current condition of the ductwork and assess how it will perform with your new unit.

Will a New Furnace Lower My Energy Bill?

Yes. More than likely, a new furnace t will lower your energy bill..

As HVAC systems age, they lose their efficiency. This means that they require more energy  to achieve the same results.

In addition to the natural degradation that occurs as the unit ages,, HVAC technology is constantly improving. . An older unit is less likely to have been designed with efficiency in mind. Whereas a newer unit will have a higher efficiency rating. The higher the number, the more efficient the unit.

How Can I Extend the Life of My Furnace?

Whether you are looking to extend the life of an older furnace  or you have a brand new one, here are some tips that will help keep your unit in working order.

  1. Schedule regular maintenance. As with other large machinery, maintaining your HVAC is very important. We recommend that you get your furnace serviced at least once a year by a licensed technician. The service will include an inspection, minor cleaning, and tune-up.
  2. Change your air filters. Most disposable air filters should be changed every 1 to 3 months, but thiswill vary by filter brand. If your filter is dirty, change it!
  3. Clean your air ducts. Just as you should have your furnace serviced, you should also maintain your air ducts. They are equally important in having clean indoor air quality. We recommend having them cleaned every 3 to 5 years.
  4. Install a smart thermostat. Smart thermostats allow a greater level of programming than other thermostats. Most are WiFi enabled, so you can use your smartphone or tablet to connect to it. This even allows you to adjust the temperature when you are not home. Smart thermostats can also help you save money on your energy bill.
  5. Upgrade your insulation. If your current insulation is insufficient, your HVAC unit will work harder to make up the difference. Over time, this puts excessive strain on your machine. Upgrading your insulation helps ensure that your home keeps the cold or warm air inside.
  6. Use the auto setting. HVAC fans have two settings: auto and on. When the “on” setting is used, the fan runs constantly. This wears it down faster. Instead, use the “auto” setting. With this setting, the fan only runs when the system is actively heating your home.
  7. Get repairs done in a timely manner. If you notice that your system is not working as efficiently as it once did, don’t wait to call us. . Letting the issue go unresolved  can cause more problems in the long run. It also puts more strain on your system, so it is important to  get it fixed immediately.
