Services Offered by Furnace Repair Companies

Furnace repair providers offer a number of services to help your furnace work at maximum efficiency. We go over some common services below.

Repair and Maintenance

Timely repairs restore your furnace's function, extend its life span, and optimize energy efficiency. Furnace repair providers can diagnose and repair any furnace issue, including a malfunctioning thermostat, clogged air filter, or broken blower motor. Qualified HVAC technicians examine and fix individual problems including faulty ignitions, malfunctioning thermostats, possible gas leaks, or damaged heat exchangers. Furnace repair technicians can also complete routine HVAC maintenance to avoid unnecessary breakdowns. This might involve inspecting and cleaning your furnace, lubricating moving parts, replacing air filters, and ensuring all components function optimally.


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


If you find that your furnace isn’t turning on, your furnace repair company will recommend a thorough inspection to identify possible causes. This will involve a technician examining each component of your furnace. Inspections typically include examining the heat exchanger for cracks or damage, checking for any gas or fuel leaks, inspecting the burner and ignition system, cleaning and replacing air filters, and testing the thermostat's accuracy. The technician verifies the heating system's efficiency and safety while making the necessary adjustments or repairs. Routine, annual furnace tune-ups ensure optimal performance, help avoid potential breakdowns, and promote safe living during cold winters.

Emergency Services

Emergency furnace repair services can help with unexpected malfunctions, breakdowns, or other safety concerns. Many companies offer these 24/7 services to help get your system back up and running promptly outside of normal business hours. Furnace failure can cause serious discomfort and health risks from the reduced indoor air quality, especially if it breaks down during extreme weather and it's not possible to open windows for fresh air. Emergency services may be more expensive than a scheduled service, but protecting your health is worth it.

Factors To Consider When Choosing a Local Merrillville Furnace Repair Service

There are a number of important considerations for choosing a local Merrillville furnace repair service. We go over some important factors below.

  • Cost: Look for a company that provides all the services you need, and that offers transparent and competitive pricing. Compare several Merrillville furnace repair companies. Beware of ones that offer extremely low rates, as they may employ low-quality workmanship or subpar replacement parts.
  • Guarantees: Ask your furnace repair company about any warranties or guarantees it offers. Reputable service providers offer these guarantees to protect customers if any problems come up post-repair. Guarantees can cover both parts and workmanship.
  • Licensing: Confirm that your furnace repair provider has all required licenses and certifications. This ensures that its technicians are qualified and trained to safely handle furnace repairs. In Indiana, your HVAC contractor must obtain certification from your local city or municipal government.
  • Qualifications: Check the qualifications and experience of a furnace repair company. Ideally, technicians should be well-trained and have expertise in various furnace makes and models. Ask about ongoing training programs to ensure a company keeps up with the latest repair techniques.
  • Reputation and reviews: Online reviews and customer testimonials often paint a picture of a company's reputation and focus on customer satisfaction. Choose a company with overall positive reviews and experiences, and pay attention to the way it addresses complaints and negative feedback.

How Much Does a Furnace Repair Cost?

The total cost of furnace repair will vary depending on factors including the type of HVAC unit you have, the extent of the damage, and the price of replacement parts. The final total may vary, but expect to spend an average of $429 on furnace repair. The following are some common furnace repairs, as well as their average costs.

  • Broken thermostat: $80–$398
  • Cleaning: $48–$64
