A Brief Background on Furnaces in Commercial Applications

The furnace is the component of your HVAC system that generates heat. In gas-powered central HVAC systems that use ductwork, here is how a furnace works:

  1. The thermostat signals the furnace to turn on
  2. The burners ignite and deliver heat to a heat exchanger
  3. Blowers move air over the heat exchanger into ducts that distribute heat around a space.

3 Signs it Might Be Time to Replace Your Furnace

While the prospect of repairing or replacing your HVAC equipment can seem daunting, it is important to keep your furnace in good working order. So regardless of whether you notice any of the signs below, it is best not to wait for something to go wrong: Preventative maintenance can help identify issues early which could help avoid costly breakdowns and unplanned downtime. Regular inspections may also help ensure your system is running right when you need it most!

1. The Age of Your Furnace

The longevity of a furnace depends on a number of factors. such as:

  • The usage demands
  • The initial installation
  • The amount/quality of maintenance over time

Aside from general wear and tear over time, older furnaces may be less efficient which could be costing your business. So while putting off a furnace or HVAC replacement might seem like it is saving you money, it may not be the best decision.

Tip: If your furnace is more than 15 years old but you are not noticing any obvious problems, it is always a good idea to contact a trusted, certified HVAC technician to get a professional opinion and to ensure it’s operating at peak performance.

2. Frequent Repairs

While routine maintenance is a great way to help keep your furnace running properly, there is a big difference between preventative maintenance and the constant need for regular repairs. Sometimes, when a furnace is nearing the end of its life, it breaks down and needs repairs more regularly. If you have recently had one part of your furnace replaced only to discover that something else needs to be repaired, it could mean that it is time to think about a new unit.

3. Rising Utility Costs & Declining Performance

If you are noticing spikes in your utility bills, you might want to see if there is a more efficient product available to help keep your bills in check.

Thanks to advances in technology, newer furnace models can run efficiently than older units. By upgrading to a newer furnace, you may be able to take advantage of increased efficiency and lower your energy bills. For more information, be sure to consult a trusted HVAC service provider on the energy ratings associated with different models. For example:

AFUE: This is a seasonal measure of how well a furnace is able to convert the amount of energy used to heat. The higher the number, the more efficient your furnace will be.

3 Signs It Might Be Time To Repair Your Furnace

If you notice any of the signs below, it is time to consider a system tune-up from an expert you can trust. While these signs do not definitively indicate it is time to replace your furnace, they could signal it is time for repair or preventative maintenance.

Excessive Noise

If you hear unusual banging, clanging, buzzing, or high-pitched sounds, this could point to loose parts, broken parts, debris, and other issues. Shut the unit down and call a technician right away.


Rust is also a concern to watch for. Furnaces may develop rust over time which could be a sign that there is an issue, such as a condensate leak.

Clogged and Dirty Filters

Filters play an essential step in keeping your HVAC system running cleanly and efficiently. Commercial business owners should regularly have their filters inspected and replaced to ensure that they are not clogged with dust, dirt, and debris. If left unattended, a clogged filter can restrict airflow and cause problems in the unit.
