The most typical furnace issues are:

  • Poorly Maintained Ductwork
  • Used-up Filters

Let’s break down each of these typical furnace issues and learn how to resolve these.

Gas Furnace Repair Solutions for Your Home

Cleaning Air Ducts – Cleaning Vents Before Repairing a Furnace

Dust and other debris can occasionally enter your heating ducts. That cuts down on how much warm air you’ll get.

If you’ve noticed that your home isn’t getting as warm as it used to when the furnace was running, it may be time to clean the ducts. Put your palm in front of the vents to feel how much air is coming out to make sure the airflow is working properly.

Get on a regular maintenance plan with a reliable Buford heating and air company to forestall the need for emergency repairs. Don’t worry about your heating being interrupted while we clean your ducts and the HVAC system.

Changing Filters:

The filter in your furnace serves to clean both the air and the ducts. The filter helps keep the air clean by removing contaminants like dust, pollen, and pet dander.

While most homeowners are aware that their furnaces require filters, only some know how often these filters should be replaced. Filters should be changed every month or two.

Inadequate heating from the furnace is a telltale indicator that the filter needs to be changed. A dirty filter may also cause your furnace to work harder than it should. This is because the filter is clogged, making it difficult for the furnace to function. 

Repairing the Ignition System

Each heater has a special switch that kick-starts the combustion process. The type of mechanism relies on the furnace itself.

Typically, this is a pilot light in an older model furnace. Most modern heating systems don’t require pilot lights anymore and instead rely on electronic ignitions.

We may need to replace or repair your furnace’s ignition or pilot light, regardless of the model. When there’s an issue with the furnace’s ignition or pilot light, it can stop firing up and heating the house.

The furnace’s pilot light may be visible from the outside. However, if your furnace isn’t starting when it should, you should contact a professional.

Fixing Your Thermostat – Gas Furnace Repair

The problem with your furnace may be something other than the furnace itself.

Your thermostat measures home temperature. That determines when the furnace heats up.

A broken thermostat may read the wrong temperature. This causes your furnace to create unnecessary heat or stop producing heat in cold rooms.

Your thermostat may transmit incorrect messages to the furnace. An electrical issue might arise at any time.

An HVAC professional can diagnose software or hardware issues with your thermostat. We can repair or replace your thermostat.

Circuit Breaker Tripped

A temporary power surge may trip a furnace’s circuit breaker. If resetting the breaker fixes the system, you’re good. However, frequent tripping concerns.

You may share a circuit with your furnace and other large appliances. Ground problems in the circuitry could have also caused energy to flow.

You must investigate electrical maintenance and repair. Try running the furnace alone or separating its circuit board.

Unexpected sounds

Noises coming from your furnace are a telltale sign that something is wrong. Sounds like clunking, banging, screaming, and others are possible.

Squeaking sounds usually indicate a problem with the blower belt previously. If you hear a scraping sound, it probably means that your blower bearings are worn out. However, there are many outcomes possible with a clunking sound.

Odors or Gas Leaks

Starting the season with the furnace on will give it a mild burning smell. Dust layers build up in the system and burn off as it heats up. Once or twice, this fragrance should fade within an hour.

Otherwise, furnace smells are concerning. The smell of mold implies allergies and trash.

If you smell gas or metal, respond immediately. Turn off the gas and open all windows and doors. Contact a gas furnace repair service immediately and vacate the house.

Why Choose Indoor Comfort?

We provide a professional and well-equipped team that repairs the furnace issues and keeps customer satisfaction as their first priority. 


In conclusion, a well-functioning gas furnace is essential for home comfort and safety. Understanding common gas furnace repair recommendations can save homeowners and business owners from discomfort. 

Just make sure that airflow and heating efficiency require regular maintenance, including air duct cleaning and filter replacement. Keeping your furnace in good condition requires rapidly fixing ignition system failures, thermostat malfunctions, tripped circuit breakers, strange noises, and gas odors.

Frequently Asked Questions

Q1: What kind of furnace failure is common?

A1: Ignite Failure – One of the most prevalent furnace issues is ignition system failure. When the ignition fails, the furnace cannot produce hot air. Due to off-burners, the furnace will not start.

Q2: How does a gas furnace work?

A2: The simple version: Burning propane or natural gas heats the furnace burner. A heat exchanger heats the produced heat. A heat exchanger warms air from the home’s ducting.

Q3: How do gas furnaces start?

A3: The thermostat or control system opens gas burner valves to burn fuel when heat is needed. The gas passes over the igniter to start a fire. The burners heat the heat exchanger with this flame.
