Services Offered by Furnace Repair Companies

Furnace repair companies offer a number of services to keep your furnace working effectively and efficiently. We review common services below.

Repair and Maintenance

Timely repairs restore furnace function, extend its life span, and optimize energy efficiency. Your furnace repair provider can handle a number of issues, including broken blower motors, malfunctioning thermostats, and clogged air filters. Qualified HVAC technicians are also experienced in tackling problems like faulty ignitions, possible gas leaks, damaged heat exchangers, and malfunctioning thermostats. Furnace repair experts can also provide routine HVAC maintenance to avoid unnecessary breakdowns. This can include jobs such as inspecting and cleaning your furnace, replacing air filters, lubricating moving parts, and ensuring that all components work correctly.


Your HVAC provider can help upgrade your furnace to a more energy-efficient model, such as a heat pump. If your system is beyond repair, they can also help install an entire new furnace. Your technician will begin by assessing your heating needs and home’s layout. Then, the tech will recommend the right furnace model for your requirements and budget. HVAC technicians follow safety protocols and standards set by the industry to ensure proper furnace replacement and connection. They can also integrate a new system with existing air ducts and thermostats. After installation, the company will complete a final inspection to confirm that the furnace runs optimally and efficiently.


You likely need an inspection if you discover that your furnace isn’t turning on. A technician will thoroughly inspect each part of your furnace to look for potential issues. Inspections normally include examining the heat exchanger for cracks or damage, inspecting the burner and ignition system, testing the thermostat's accuracy, cleaning and replacing air filters, and checking for any gas or fuel leaks. Yearly inspections of this type facilitate optimal heating system performance, help avoid possible breakdowns, and promote safe living during cold winters. The technician will verify your system's safety and efficiency and make the necessary repairs.

Emergency Services

Emergency furnace repair services will restore heat to your home if your furnace breaks down on a cold winter night. Many companies offer 24/7 services to help get your furnace up and running as soon as possible. These services help with unexpected breakdowns, malfunctions, and other safety concerns. Furnace failure can cause discomfort and serious health risks due to reduced indoor air quality, especially if it breaks down during extreme weather and you can't open windows for fresh air. Emergency services might be more expensive than a scheduled service, but protecting your health is worth it.

Factors To Consider When Choosing a Local Gary Furnace Repair Service

You should consider a number of factors when choosing a local Gary furnace repair company. We go over some of the most important below.

  • Cost: Compare pricing from several Gary furnace repair companies. Look for transparent and competitive pricing, considering the scope of services offered. Stay away from extremely low-cost options, which may compromise workmanship quality or involve subpar replacement parts.
  • Guarantees: Warranties and guarantees offer you peace of mind should problems come up after a repair. Trustworthy furnace repair companies should stand behind their work with warranties or guarantees for both workmanship and replacement parts.
  • Licensing: Make sure your furnace repair servicer holds the required local and state licenses and certifications. Proper licensing ensures the technicians are qualified to handle furnace repairs safely and effectively. In Indiana, your HVAC contractor must obtain certification from your local city or municipal government.
  • Qualifications: Ask about the qualifications and experience of a furnace repair company. Ideally, you want technicians that are trained and experienced in working with various furnace makes and models. Inquire about company training programs to confirm that technicians are educated on the latest industry standards for repairs.
  • Reputation and reviews: Browse online reviews and testimonials from previous customers to get a sense of a company's reputation. Look for a provider with overall positive reviews, but also be mindful of how it addresses negative reviews and complaints. This can tell you a great deal about a company's commitment to customer service.

How Much Does a Furnace Repair Cost?

The total cost of furnace repair will vary depending on factors such as the type of HVAC unit you have, the extent of the damage, and the price of replacement parts. Your final price may vary, but expect to spend an average of $436 on furnace repair. Below are some common furnace repairs and their average costs.

  • Broken thermostat: $80–$402
  • Cleaning: $48–$64
  • Cracked heat exchanger: $1,606–$2,811
  • Damaged blower bearings: $24–$120
