When your boiler breaks down, the first thought that pops up is usually, “How much is this going to cost me?”

In Colorado, the cost of a boiler repair ranges from $129 to over $9,000 with most paying around $659 on average.

We know that’s a huge price range. That’s because the cost to repair your boiler can vary depending on the following factors:

  1. What’s wrong with your boiler
  2. Whether your boiler is still under warranty
  3. The HVAC contractor you hire

We’ll go into more detail about each of these factors below.

Three cost factors of a boiler repair

1. What’s wrong with your boiler

What’s actually wrong with your boiler plays the biggest role in how much your boiler repair will cost you. That’s because some boiler repairs simply cost more than others.

For example, some common boiler repairs we see include:

  • A faulty circulator pump, which can cost anywhere from $600 to over $1,500
  • Sediment buildup in the boiler, which can cost upwards of $600
  • Leaks in/around boiler components, which vary widely in price anywhere from $200 to $9,000 (if you need to completely replace a corroded boiler)
  • A broken ignitor, which typically costs around $200 to $300+ to replace

As you can see, the cost of each boiler repair above varies widely.

Keep in mind, though, that you won’t know what’s wrong with your boiler (and therefore how much the repair will cost) until you have a tech inspect and diagnose the system.

Only after a technician inspects and diagnoses your boiler’s issue will you have a better idea of where you fall in that $129-$9,000 price range. 

After a thorough diagnosis, the boiler tech will have a better idea of whether or not replacement parts will be needed and how much those replacement parts will cost. Plus, the tech will be able to estimate the hours of labor that your repair should take.

2. Whether your boiler is under warranty

After seeing those prices above, you might be even more worried about the cost of your boiler repair.

The good news is that if your boiler is still under warranty, you won’t have to pay as much out-of-pocket for your repair.

You see, when your boiler was first purchased and installed, it likely came with two warranties:

  1. A parts warranty from the manufacturer. With a parts warranty, if a part fails within a certain timeframe (usually anywhere from 2 to 5 years after the boiler was installed), then the manufacturer will cover the cost of the replacement part. 
  2. A labor warranty from the contractor. With a labor warranty, if something goes wrong in the first 1-2 years (length depends on the contractor), the contractor will cover the cost of the labor to fix the problem.

To check the status of your warranties or to get details about what they cover, contact the manufacturer of your boiler or the HVAC contractor who installed the system.

Beware, though—in order for your parts warranty to be considered valid, the manufacturer typically requires you to do the following:

  • Register your boiler within 60 days from its installation date (the length of time varies according to the manufacturer)
  • Prove that your boiler has been regularly maintained by a certified professional
  • Prove that the system has not been moved from its original location and that only OEM (original equipment manufacturer) replacement parts have been used on any/all repairs

If you can’t satisfy the stipulations above, the manufacturer may not honor your boiler parts warranty.

3. The HVAC contractor you hire

Some contractors charge more for their repair services than others. The typical rule of thumb is that the more experienced the HVAC contractor, the more they typically charge for boiler repairs.

But keep in mind that with higher-quality boiler repair pros, you’re essentially paying for a job that’s done right the first time around. And that saves you time and money in the long run.

That said, we strongly suggest choosing to pay more upfront for a high-quality boiler repair. Otherwise, you could find yourself having to pay more in the long run for costly repeat work or worse—a shoddy repair that causes the system to die prematurely.

To find a high-quality boiler repair contractor, make sure that the company you choose:

  • Has good customer reviews on sites like Google and the Better Business Bureau (BBB)
  • Is licensed and insured in the state of Colorado
  • Provides upfront pricing in writing for their boiler repair services
  • Offers guarantees on their work (i.e. at least a 1-year labor warranty on their boiler repairs)
