Services Offered by Furnace Repair Companies

You can employ a local furnace repair company for a number of services that help your furnace run efficiently. We go over some common services below.

Repair and Maintenance

Professional and timely repairs can restore your furnace's function, extend its life span, and optimize energy efficiency. Furnace repair companies can diagnose and fix most common furnace issues. These include clogged air filters, malfunctioning thermostats, or broken blower motors. Qualified HVAC technicians can also handle problems such as damaged heat exchangers, faulty ignitions, malfunctioning thermostats, and possible gas leaks. Your furnace repair company can also perform routine HVAC system upkeep to help avoid unnecessary breakdowns. Your technician will ensure that all components function properly by inspecting your furnace, cleaning it, replacing air filters, and lubricating moving parts.


HVAC companies can help mount a new furnace if yours is past repair. An expert can also help with upgrading to a more energy-efficient model, such as a heat pump. First, a skilled technician will assess your heating needs and home’s layout. Then, the tech will recommend the best furnace model for you based on your requirements and budget. Your HVAC installer can integrate your new system with your existing air ducts and thermostat. They're trained on industry standards and safety protocol for proper exchange of the existing furnace and connection. Following installation, the technician will perform one last inspection to ensure your furnace runs properly.


You probably need an inspection if you notice your furnace isn’t turning on. A technician will thoroughly inspect each part of the furnace to look for potential issues. Inspections usually include cleaning and replacing air filters, examining the heat exchanger for cracks or damage, testing the thermostat's accuracy, checking for any gas or fuel leaks, and inspecting the burner and ignition system. During an annual inspection, a technician will verify your heating system's efficiency and safety and make any necessary adjustments or repairs. Regular inspections help prevent potential breakdowns, ensure optimal heating performance, and promote safe living during colder months.

Emergency Services

Emergency furnace repair services are there to help with unexpected malfunctions, breakdowns, or other safety concerns. Many companies offer these 24/7 services to get your system up and running promptly outside of normal business hours. Emergency services may cost more than scheduled service, but it's worth it to protect your health. If your furnace fails during extreme weather conditions, and you're unable to open windows for fresh air, it can cause serious discomfort and health risks due to decreased indoor air quality.

Factors To Consider When Choosing a Local Sumter Furnace Repair Service

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

  • Cost: Compare service offerings and prices among several Sumter furnace repair providers. Look for transparent and competitive pricing, but avoid extremely low-cost options. Abnormally low prices may indicate that a company is making up the difference by compromising the quality of work or materials.
  • Guarantees: Look into the guarantees or warranties provided by the furnace repair provider. A trustworthy company should stand behind its work and offer a reasonable guarantee on repairs and replacement parts. This provides peace of mind knowing you can rely on your service provider if problems arise after repairs.
  • Licensing: Verify that your furnace repair servicer holds all required licenses and certifications. This ensures that its technicians are qualified and trained to safely handle furnace repairs. HVAC contractors in South Carolina must obtain a contractor's license from the South Carolina Residential Builders Commission.
  • Qualifications: Look into a furnace repair company's qualifications and experience. Your service provider should employ technicians that are well-trained and have experience with various furnace makes and models. Inquire about a company's training policies to make sure they stay on top of the latest industry standard repair techniques.
  • Reputation and reviews: You can learn about a company's reputation by checking online reviews and testimonials. A strong positive reputation is a likely indicator of high-quality services. Look at how the provider addresses negative feedback or complaints, reflecting its commitment to customer satisfaction.

How Much Does a Furnace Repair Cost?

The total cost of furnace repair varies depending on factors including the type of HVAC unit, the extent of the damage, and the price of replacement parts. The final total may vary, but on average expect to spend around $364 on furnace repair. Below are some common furnace repairs and their average costs.

  • Broken thermostat: $72–$358
  • Cleaning: $43–$57
  • Cracked heat exchanger: $1,434–$2,509
  • Damaged blower bearings: $22–$108
