4 Warning Signs That It’s Time to Repair Your Furnace

When is the last time you thought about your furnace’s health? If you’re like most people in Omaha the answer to that question is never- until it stops working. If your furnace is still under 10 years old, you most likely would not want to invest in a replacement unit already. With the proper maintenance, a furnace can last up to 15-20 years. So, what are the four major signs you should be looking for to determine if your furnace needs some repair work? McCarthy’s One Hour Air has the signs you should be looking for to call in a furnace repair. 

1. The Temperature Has Dropped

The first sign is the most obvious that your furnace needs repair – your house feels cold even when you set the temperature higher. The job of a furnace is to provide heat for your home, so if it is blowing cold air, you have a problem. There could be many reasons why your furnace is not heating properly. Fortunately, the solution can be as simple as having your pilot light out. So, take a peek inside and call your local heating specialist at McCarthy’s One Hour. Other quick ways to troubleshoot a cool furnace are to check your thermostat is functioning and make sure the air filter is clean. These can also impact your furnace’s ability to heat the home.

2. You Smell Gas

The second sign you have a furnace that needs a repair- you smell gas. If you have a furnace which doesn’t run on natural gas or propane, then relax. If you have a gas run furnace – this is the most serious issue you can encounter. Detecting the smell of gas in your home could be a matter of life and death, so swift action is required.

A gas leak is very serious business and should be addressed by you before you call for a repair. If the odor of gas is so easily detected that there’s no question what is happening, you could be in immediate danger.

Before any repair services are called, you should:

  • Open all the windows in your house
  • Turn off the furnace immediately
  • Switch off the gas lines to stop the gas flow wherever it may be
  • Evacuate the premises until you can no longer smell the fumes

Gas can ignite with the smallest spark, so avoid any flames or sparks during this process. 

Fortunately, almost all gas leaks in a furnace come from the unit’s heat exchanger. This essential part of the furnace may be broken, but they can be easily replaced by a heating technician from McCarthy’s One Hour. If you schedule regular maintenance, many issues with your furnace can be caught before a repair is needed.

3. Liquid Collecting Under The Unit

A puddle of liquid collecting under the heating system is a reason to call for a furnace repair. There are two types of liquid that would most likely be pooling around your furnace: water and gasoline. Either liquid left to collect isn’t good news. Water leads to rust, corrosion, and mold in your system or home. It can damage the area that holds your furnace and could be costly to clean and resurface. Gasoline is even more dangerous than water because it can be a threat to your entire house. With any spark, the gas could catch and a fire could break out. 

With the presence of either liquid, your best bet would be to shut off your furnace. Water and gas are both harmful to your furnace and should be addressed immediately. 

4. Unusual Noises

Your furnace shouldn’t be making any noises besides normal humming sounds. If any high-pitched squeals, thumps or bangs happen, the noise is most likely from a loose part in the furnace. The longer this is left to moving around or broken, the more damage can be done to other parts of the furnace. It can mean a more expensive furnace repair or a possible replacement if there’s too much damage. Scheduling a furnace repair with McCarthy’s One Hour at the first signs of trouble will save you money in the long run.


Whether it’s no heat, the smell of gas, liquid puddles, or odd noises – it’s important to take any changes with your furnace’s performance seriously. Regular furnace repair and maintenance may not only lower your utility bills but in the case of leaking gas, can save your life.
