Having heating problems? In need of a furnace repair?. If so, you may be wondering how much a repair may cost you.

On average, the cost of a furnace repair in Colorado can range anywhere from $129 to $1,119. The price range may seem large, but the overall cost will depend on the kind of repairs needed for your unit, along with other factors such as: 

  • Scope of work required
  • Age of your furnace 
  • Valid warranties 
  • The contractor you hire 

In this blog, we’ll examine how each of these factors impacts the overall cost of a furnace repair. But first, we’ll go over the signs you should look for to determine whether or not your furnace needs repair.

Signs your furnace needs repairing 

Before you consider how much to dish out on a furnace repair, knowing the signs of a faulty furnace is the first step.

Your furnace may needs repairs, if:

  • It’s generating unusual smells.
  • It’s making loud and persistent noises, like squealing, whistling, or banging. This could indicate a broken fan or belt, or further damage to internal components.
  • It’s increasing the humidity in your home
  • It’s unevenly heating your home 
  • It’s producing excessive amounts of soot or dust

If your furnace has a problem you can’t explain, or you’re unsure if you need a new furnace, be sure to contact an HVAC technician for a professional inspection and diagnosis.   

Scope of work required

The more work needed for a repair will require more labor, costing you more for your repair. For example, replacing the coils inside your furnace could take up to four hours. While repairing an ignitor, one of the more common issues on a furnace may require only an hour to fix.

The size of the unit and the type of fuel your furnace needs also affect the cost. The smaller the unit, the more affordable the repair. For instance, filters, fans, and motors all depend on the size of the HVAC unit. At the same time, a unit that runs on gas might run cheaper than a unit that is an oil or an electric furnace. 

The age of your furnace 

On average, a furnace could last about 15 years, and sometimes longer if it’s well maintained. If your furnace is 15 years old or older, the cost of your repair will likely be higher. That’s because older furnaces could have multiple components that are worn out.

While a furnace can last for a while, parts within the furnace tend to have a shorter lifespan. Components like a furnace ignitor may need to be replaced in as little as five years, while a pressure switch that shuts the furnace down if it senses negative pressure can last up to 10 years.  

Whether or not you have valid warranties 

If your furnace’s manufacturer’s warranty is still valid, your repair will cost less. Check with the manufacturer of your furnace. Usually, the warranty lasts up to 10 years and covers certain parts and repair costs. Keep in mind, a manufacturer’s warranty may not cover the cost of labor. That means if you need a $500 part replaced, you’ll be reimbursed for the cost of the part, but not for the cost of the labor to install it. Warranties are typically only valid if:

  • It is registered properly 
  • You have annual maintenance by an HVAC professional 
  • Only approved parts or standard parts provided by the manufacturing company are used on your unit

Some HVAC companies offer free in-home estimates, while others may require a diagnostic fee. This fee pays to understand the “why” behind your furnace problems. A diagnostic fee typically starts around $129 but can increase if the repair calls are after regular workday hours.

The contractor you hire

The company or contractor you hire will have a significant impact on your furnace repair cost. Typically, the longer a contractor has been in business, the greater their reputation, and the more they may charge based on that experience. That said, a more reputable, experienced technician will likely do a better job than a lesser-qualified contractor.

Going with a technician that costs less might be tempting, but consider what it could mean for your furnace repair. Homeowners who consistently choose the lower-priced repair might find themselves fixing the same issue months later.

So, how do you know they’re right for you? It’s simple, they should:

  • Provide proof of a license 
  • Have good reviews on sites like Google and Yelp 
  • Offer labor warranties for the job
  • Provide an upfront, written estimate
