Services Offered by Furnace Repair Companies

Furnace repair companies provide various to help your furnace work at maximum efficiency. We outline some common offerings below.

Repair and Maintenance

Timely repairs restore furnace function, extend its life span, and optimize energy efficiency. Furnace repair companies can diagnose and repair any common furnace issues. These include clogged air filters, malfunctioning thermostats, or broken blower motors. Qualified HVAC technicians can also handle problems such as possible gas leaks, damaged heat exchangers, faulty ignitions, and malfunctioning thermostats. Furnace repair technicians can also complete routine HVAC maintenance to avoid unnecessary breakdowns. This may involve inspecting and cleaning your furnace, replacing air filters, lubricating moving parts, and ensuring all components function optimally.


Your local HVAC expert can 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 a new furnace. Your technician will start by assessing your home's layout and heating needs. Then, the tech will recommend the best furnace model for your budget and home requirements. An HVAC professional can integrate a new system with existing thermostats and air ducts. They're trained on industry standards and safety protocols to ensure proper furnace replacement and connection. To ensure everything runs optimally, your technician will complete a final inspection following installation.


You should schedule an inspection with a furnace repair company if you notice that your furnace isn’t turning on. During the inspection, a technician will look at every component of your furnace to identify potential causes. The inspection normally includes testing the thermostat's accuracy, inspecting the burner and ignition system, examining the heat exchanger for cracks or damage, checking for any gas or fuel leaks, and cleaning and replacing air filters. The technician verifies the heating system's safety and efficiency, making necessary repairs or adjustments. Routine, annual furnace tune-ups encourage optimal performance, help avoid potential breakdowns, and promote a safe living environment during frigid winters.

Emergency Services

If your furnace breaks down in the middle of the winter, furnace repair companies may have emergency repair services to get your system up and running quickly. These services are available around the clock for unexpected breakdowns, malfunctions, and other safety concerns outside regular business hours. Emergency services might cost more than scheduled services, but it's worth it to protect your health. If your furnace fails during extreme weather conditions, and you can't open windows for fresh air, it can cause serious discomfort and health risks from decreased indoor air quality.

Factors To Consider When Choosing a Local Janesville Furnace Repair Service

  • Cost: Look for a company that provides all the services you need, and that offers transparent and competitive pricing. We recommend comparing multiple Janesville furnace repair companies. Beware of ones that offer extremely low rates, as many employ low-quality workmanship or subpar replacement parts.
  • Guarantees: Warranties and guarantees offer you peace of mind in case problems come up after a repair. Trustworthy furnace repair providers should back their work with warranties or guarantees for both workmanship and replacement parts.
  • Licensing: Verify that your furnace repair servicer holds all required licenses and certifications. This ensures that its technicians are qualified to handle furnace repairs safely and effectively. HVAC contractors in Wisconsin must obtain a contractor's license from the Wisconsin Department of Safety and Professional Services.
  • Qualifications: Look into a furnace repair company's qualifications and experience. A company should employ well-trained technicians who 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: Online reviews and customer testimonials can give you an idea of a provider's reputation and commitment to customer satisfaction. Choose a company with overall positive reviews, and pay attention to the way it addresses negative feedback or complaints.
