10 Signs That You Need a Furnace Repair

Did you know that the market size of HVAC systems was over $240 billion in 2019? By 2024, the number of HVAC units sold is expected to pass 150 million.

Your home, like most American homes, probably has an HVAC system. Depending on the condition of your system you might need furnace repair.

This guide will discuss some of the signs to look for. Keep reading to learn what they are.

1. Strange Noises

One of the most obvious signs of furnace issues can be heard before anything is seen. If you start hearing a buzzing noise coming from your furnace this might be a sign of an electrical problem.

A subtle hum is a sign of a normal furnace running its cycle, anything else can indicate trouble. If you hear your furnace popping, rattling, or scraping this could indicate something more serious going on with the unit.

2. Poor Air Quality

You should consider calling a furnace repair company if you notice the air quality in your home declining. This is a sure sign of a malfunctioning HVAC system.

Poor air quality means the air isn’t flowing as it should and you’ll feel uneven temperatures throughout the rooms in your house. A broken furnace will keep dust and mold spores in the air, risking your health. If your home feels dry or stuffy consider calling the professionals.

3. Constant Starting and Stopping

If you notice your furnace starting and stopping too often, before it’s able to finish a heating cycle, this is a sign of mechanical issues with your unit.

While this specific issue could be caused by a long list of malfunctions, you shouldn’t try finding the problem on your own. When you try to DIY furnace repair you can make things worse. Wait for a trained technician who can help you find the root of the problem.

4. A Strange Smell

If you start smelling different odors coming from your heating system, the first thing you should do is call a furnace repair service. If your furnace stopped turning back on and you notice the smell of gas this could indicate a broken system.

It’s not smart to stay inside a house that smells like gas, this could be dangerous to your health. Go outside and call for help right away. Many furnace repair companies offer emergency services.

5. When You Need to Adjust Your Thermostat Often

If all the rooms in your home aren’t getting the same airflow and aren’t at the right temperature you might find yourself adjusting the thermostat more often than you did before. When you need to adjust your thermostat constantly this is a sign that there’s something wrong with your furnace.

While it could also mean that your thermostat is having issues regulating the temperature throughout your home, the bigger issue is with your furnace that isn’t distributing heat as it should.

6. Too Much Indoor Moisture

Another sign that can help you figure out if you need to call an HVAC company for repairs is if you notice an increase in moisture inside your home. If you see more moisture in certain rooms around the windows or on the ceiling this means that the air isn’t flowing as it should throughout your home.

This condensation and stagnant air mean that your furnace needs to be examined by a trained technician to make the necessary repairs.

7. When You Notice a Leak

A leak is the most common sign that you need repairs completed on your furnace. Don’t try to repair a small leak on your own. If you don’t do the job correctly it can turn into a bigger issue and put your system at risk of more severe damage.

A leak caused by a cracked line should only be examined and repaired by someone with the proper training. Check out Trust 1 Services for more information on repair services you might need.

8. A Higher Utility Bill

A higher utility bill is most often associated with a malfunctioning HVAC system. When your system has issues it needs to work harder to heat your entire home. An overworked system will require more energy which translates to a more expensive electricity bill.

Consider getting heating and cooling repair so that your system can work as efficiently as possible and lower your utility bill to a more reasonable price.

9. Signs of a Pest

Pests can do a lot of damage to your property, this includes your HVAC system too. Any signs of an animal around your system can lead to heating issues down the line.

If you see any kind of nest or droppings you need to get your system inspected right away. If the rodents have been there enough time they could chew through wiring and break down your heating system.

10. If You Feel Cold Air Coming From Your Furnace

You’ll need heater repair if there’s cold air flowing through your home when you turn on the furnace. Cold instead of warm air when you try to use your heating system means your furnace has a mechanical issue. A professional will fix this issue for you before it breaks down your entire unit.
