Common problems with gas furnaces

Before we dive into the details of who fixes gas furnaces, let’s take a look at some common problems homeowners may encounter with their gas furnaces.

Lack of heat

The most common issue with gas furnaces is a lack of heat. If your furnace is not producing enough heat, it could be due to a clogged air filter, faulty thermostat, or a malfunctioning furnace motor.

Noisy furnace

A furnace that makes loud or unusual noises could be a sign of a problem. This could be due to a loose belt, damaged fan blades, or a malfunctioning motor.

Poor air quality

A gas furnace that is not working correctly can affect the air quality in your home, leading to respiratory problems, allergies, and other health issues.

High energy bills

A malfunctioning gas furnace can cause an increase in energy bills, as the furnace works harder to produce heat. If you notice a sudden increase in your energy bills, it may be time to have your furnace inspected by a professional.

When it comes to fixing gas furnaces, there are several professionals you can turn to. Here are the most reliable options.

HVAC technicians

HVAC technicians are professionals who specialize in heating, ventilation, and air conditioning systems. They are trained to diagnose and fix problems with gas furnaces and other heating systems. Hiring an HVAC technician to fix your gas furnace ensures that the job is done right the first time, and you can rest assured that your furnace is in good hands.

Certified contractors

Certified contractors are another option for fixing gas furnaces. They are licensed professionals who have undergone specialized training and certification to work on heating systems. Hiring a certified contractor to fix your gas furnace ensures that the job is done correctly, and they can also provide you with valuable advice on how to maintain your furnace properly.

Who Fixes Gas Furnaces: DIY Options

If you’re handy and have experience working with appliances, you may be able to fix your gas furnace yourself. Here are some common DIY repairs you can try:

Safety precautions

Before attempting any DIY repairs on your gas furnace, it’s essential to take necessary safety precautions. This includes turning off the gas and electricity to your furnace and wearing protective gear, such as gloves and goggles.

Common DIY repairs

  • Clean or replace the furnace filter: A clogged filter can cause your furnace to work harder, leading to higher energy bills and reduced efficiency. Cleaning or replacing the filter can improve the furnace’s performance.

  • Check the thermostat: Sometimes, the issue with your furnace may be due to a faulty thermostat. Checking the thermostat’s batteries, settings, and connections can help you determine if this is the case.

  • Inspect the pilot light: If your furnace is not producing heat, the problem could be due to a blown-out pilot light. Checking and relighting the pilot light can solve the issue.

  • Check the gas valve: A gas valve that is not fully open can cause your furnace to malfunction. Checking the valve and ensuring it is fully open can help resolve the issue.

It’s important to note that attempting DIY repairs on your gas furnace can be dangerous and can lead to further damage to your furnace or even injury. If you’re not confident in your abilities, it’s best to leave the repairs to the professionals.

How to Choose a Gas Furnace Repair Service

Choosing the right gas furnace repair service can be a daunting task, especially if you’re not familiar with the industry. Here are some tips to help you choose the right service for your needs.


Start by researching the gas furnace repair services in your area. Look for companies with a good reputation and experience in repairing gas furnaces.


Check if the repair service has the necessary licenses and certifications to work on gas furnaces. This ensures that the technicians working on your furnace are trained and qualified to do the job.

Customer reviews

Read reviews from previous customers to get an idea of the repair service’s quality of work and customer service. Look for reviews that mention how well the repair service addressed the customer’s concerns and whether they were satisfied with the outcome.


Compare the pricing of different repair services to ensure you’re getting a fair price for the repairs. Keep in mind that the cheapest option is not always the best, and you may end up paying more in the long run if the repair is not done correctly.

Who Fixes Gas Furnaces: DIY Options and When to Call a Professional

Common DIY repairs

Some common DIY repairs for gas furnaces include replacing the air filter, cleaning the furnace burners, and checking the thermostat settings. These repairs are relatively simple and can be done by homeowners with some basic DIY skills. However, it is always a good idea to consult the furnace manual or online resources to ensure that you are doing the job correctly.

When to call a professional
