Common issues that may need repair include; a faulty thermostat, a clogged air filter, a dirty flame sensor, or a malfunctioning pilot light. In some cases, the repair may be as simple as replacing a broken part, while in other cases, more extensive work may be required.
Attempting to repair a gas furnace can be dangerous if you are not familiar with the proper procedures.

Oil Furnace Repair
An oil furnace is a type of heating system that uses oil as its fuel source. The furnace burns the oil to heat air or water, which is then distributed throughout the home via ducts or radiators.
Oil furnaces are often used in areas where natural gas is not readily available and are found in many older homes. To keep them running at their best, it’s good to have routine service visits for cleaning and oil filter replacement.
When something goes wrong, you’ll want to call a qualified professional – the furnace’s combustion chamber and oil lines require specific knowledge for an oil furnace repair. In Chattanooga, our residential and commercial HVAC technicians are highly trained and available for emergency service and routine HVAC services.
For quality work and exceptional service, call Happy Hiller for your oil furnace repair in Chattanooga!

Electric Furnace Repair in Chattanooga
In Chattanooga, furnace repairs for electric units are often caused by a faulty thermostat, a malfunctioning blower motor, a broken heating element, or a tripped circuit breaker.
To prevent needing an electric furnace repair in Chattanooga, we suggest scheduling regular full services to clean the filter and keep the blower motor lubricated. This helps with energy efficiency and indoor air quality.
Because an electric furnace is a type of HVAC system that uses electricity as its power source, you’ll need a technician that familiar with both heating and electrical systems. As the largest privately owned HVAC company in the US, we hold our technicians to the highest standards to ensure your safety and comfort.
Keep your home warm with Happy Hiller for electric furnace repair in Chattanooga!
Improve Your Air Quality with Furnace Repair in Chattanooga
For homeowners in Chattanooga, furnace repairs can have a significant impact on indoor air quality.
One way this happens is through the filter. If the filter is dirty or clogged, it can restrict the flow of air and force the furnace to work harder, which can lead to poor indoor air quality. By cleaning or replacing the filter, you can help improve the airflow and overall air quality in your home.
Another way that furnace repairs can improve indoor air quality is by addressing issues with the combustion process. For example, if a gas or oil furnace has a malfunctioning pilot light or dirty flame sensor, it can produce too much carbon monoxide, which can be dangerous. By fixing these issues, you can ensure that the furnace is burning fuel efficiently and safely, resulting in better indoor air quality.
Annual service and proactive repairs also help keep your furnace running at its best and prolong its lifespan, reducing the amount of dust, dirt, and other pollutants that can accumulate in your home.
In Chattanooga, our furnace repair specialists will help to improve the air quality inside your home, making it a safer and healthier place to live!
Commercial Furnace Repair in Chattanooga, TN
In Chattanooga, our furnace repair technicians service both residential and commercial properties.
Unlike residential, commercial HVAC systems are typically bigger and more complex than residential systems. Our professional HVAC technicians are trained to handle the size and complexity of commercial heating systems and have all the necessary tools and equipment to make sure the repair is done safely and efficiently.
Commercial furnace systems are often part of larger HVAC systems that include cooling, ventilation, and other components. As a full-service HVAC company, we’ll check and repair all the interconnected systems, ensuring everything runs smoothly.

Just like any other HVAC system in your home, sometimes problems arise with your furnace. There are several common reasons that you may need to call for furnace repair services in Chattanooga:
- Dirty air filter: Though it may seem minor, a dirty air filter can restrict the airflow to your furnace, causing it to work harder than it needs to. This can lead to increased energy bills and can even cause the furnace to overheat and shut off.
- Thermostat problems: If your thermostat is not working properly, it can prevent your furnace from turning on or cause it to turn off too soon.
- Pilot light issues: This can indicate a dirty flame sensor or a problem with the thermocouple. If your pilot light is yellow or orange, call immediately, as this can be a sign of a carbon monoxide leak.
- Blower motor problems: If the motor is not working properly, the furnace may not blow warm air. This may be caused by a bad capacitor or a problem with the belt.
- Ignition problems: If the furnace is not lighting, the problem may be a malfunctioning ignition control module or a problem with the gas valve.
If you suspect that your furnace is not working properly, it is always best to call in a professional to diagnose and fix the problem.
We offer routine and emergency services for residential and commercial furnace repair in Chattanooga. Whether it’s in the middle of the night or during the day, for service in the Chattanooga area call Happy Hiller!
If your system completely shuts down, it’s a clear sign that you need a furnace repair in Chattanooga. But if your furnace is running and it’s still cold in your home, you’re probably wondering why! There are several possible reasons, and if you’re having an issue, it’s best to call for furnace repair services in Chattanooga.
One common cause is limited airflow. If your ducts are blocked, restricted or disconnected, the warm air will not be able to circulate through your home, so you will not feel any heat.
Another is supply. If you have an oil furnace, check your fuel – if the tank is still full, there may be a problem with the fuel delivery system. If you have an electric furnace, it may not be getting enough power to run properly.
Some other causes can include dirty air filters, thermostat problems, pilot light issues, or blower motor problems.
If your furnace is running you may not think you need emergency service – but some of these issues can be dangerous if not handled correctly. Over time, one problem will often lead to another, also costing you more in the long run.
For furnace repair services in Chattanooga, give Happy Hiller a call! We’ll take the time to properly diagnose the issue and make sure your family is comfortable and warm again in no time!
The typical lifespan of a furnace depends on several factors – the type of furnace, the quality of the furnace, and how well it has been maintained.
On average, most furnaces last between 15-20 years. Gas furnaces have a slightly longer lifespan compared to electric ones and can last up to 20-30 years if they are serviced regularly.
It’s always a good idea to have a Chattanooga furnace repair technician check your furnace regularly, even if the furnace seems to be running fine. It may not be running as efficiently as it used to and may be costing you more money on your energy bills. They can help identify potential issues before they become major problems.
For full-service electric, gas, or electric furnace repair in Chattanooga, reach out to the pros at Happy Hiller. We’ll help you extend the life of your unit and keep it running in tip-top shape!
The time it takes for your heat to be restored depends on the specific issue with the furnace.
In general, a simple furnace repair such as replacing a broken part may only take a few hours, while a more complex issue could take several days to resolve. This is one of the reasons we recommend calling for furnace repair in Chattanooga at the first sign of a problem.
The best way to get an estimate for how long it will take to restore heat after a furnace repair is to give us a call and ask for an estimated completion time. We keep our trucks fully stocked for residential and commercial emergency services and furnace repairs in Chattanooga and have techs on staff 24/7.
At Happy Hiller, we’ll take the time to understand the issue and hear your concerns – no rushing through conversations – but also work quickly and efficiently to ensure your HVAC repair is completed as quickly as possible!
It’s a good idea to have your furnace inspected at least once a year, typically before the cold season. This way, any potential issues can be caught early on and addressed before they turn into bigger problems.
During an inspection, a professional will check for any wear and tear, ensure that all parts are working properly, and make any necessary adjustments. This can help to extend the life of your furnace, improve its efficiency, and ensure that it is running safely.
When you get your furnace inspected, it’s a good time to have a tech inspect your plumbing, heating, and air quality too. We’re HVAC services experts and understand that all of these systems are connected. Starting a routine to have your HVAC systems inspected – air conditioners, furnaces, heat pumps, hot water heaters – keeps your home comfortable and safe all year long!
