Unexpected Increase in Gas or Electric Bills:
Your system may be less efficient if your energy expenditures are rising.
Do you have any questions regarding the significant rise in your gas and electric bills? Your furnace’s age is the cause of the problem. As they utilize mileage increases, furnaces become less efficient. If the heat exchanger is neglected during the off-season, the problem will worsen. A dull heater would also need to run the system for a longer period of time to reach the target temperature.

Abnormal Furnace Smell:
Particularly when they are turned on for the first time in a year, furnaces have a tendency to smell like the fuel they consume. As the furnace operates, most scents disappear. However, if you smell fuel strongly surrounding the appliance, if the smell develops suddenly, or if it persists over time, you might have a furnace issue.
These odors can be caused by a variety of problems, such as an internal gas leak or an excessive amount of dust. Have an HVAC expert examine the odor to ascertain its origin.
The Age of Your System:

Start by determining the furnace’s age. Your furnace may have already been installed when you moved into your house if you’re like most homeowners, which means it may have reached the end of its useful life. Look for the system’s model number, which should be on the furnace itself, or locate the owner’s manual. Depending on use and upkeep, a furnace has an average lifespan of 15 to 20 years.

Poor Air Quality:
The air quality in your home is directly impacted by your furnace system. A system that isn’t well-maintained could circulate hot air and foreign particles like dirt, bacteria, and other impurities throughout your house. More airborne dust may be present, and you might get frequent colds, coughs, and other respiratory illnesses. Due to the abundance of foreign particles, allergies such as itching, watery eyes, and headaches may also run in your family.
Problems with the quality of the air caused by furnaces can occasionally be solved by simply changing the filter. The ducting and unit may require professional cleaning in more severe situations.

Frequent Furnace Fixes:
Observe how frequently you have had to contact an HVAC contractor to fix your heating system over the previous two years by looking back at your repair invoices.
Recent expensive and frequent furnace repairs are a sign that your furnace needs to be replaced. You may also save money by replacing your furnace in a timely manner rather than having to pay for expensive repairs.

Persistent Noise:
No furnace is completely silent, but loud, recurring noises can point to a significant issue. When the HVAC contractor inspects the system, pay close attention to the noises you hear and, if you can, describe them to him or her. Belt or fan problems may cause squealing and whistling noises, while broken or loose internal parts may cause banging or moaning.

Gas Leaks:
Even though it should go without saying, it’s always worth repeating: if you smell a gas leak, you need to get in touch with an HVAC expert right away to deal with the issue.
Additionally, it is important to shut off the furnace right at once because the gas is extremely flammable and could catch fire with just one spark. You’re also better off leaving the house until the leak is fixed (or until a professional certifies that the furnace isn’t leaking) as an added precaution.

Water Leaks:
It’s likely that you have a water leak if you see a puddle of water near your furnace, but don’t panic; if it’s fixed right away, it won’t be difficult.
Condensation is most likely to blame for the water leak. A break in the condensation line or a clogged condensation drain could be the issue. In addition, a clogged internal drainage system or an issue with your humidifier could be the source of your water leak (if you have one connected to your furnace).
A furnace repair contractor in Corpus Christi TX can locate the problem quickly and make sure that the water leak doesn’t result in more challenging issues like mold.
