Services Offered by Furnace Repair Companies

Your local furnace repair company provides various services to keep your system working efficiently and effectively. We go over some common services below.

Repair and Maintenance

Timely repairs restore furnace function, extend its life span, and optimize energy efficiency. Furnace repair companies can diagnose and repair a number of common furnace issues. These include malfunctioning thermostats, clogged air filters, or broken blower motors. Qualified HVAC technicians can also handle problems such as malfunctioning thermostats, possible gas leaks, damaged heat exchangers, and faulty ignitions. 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 providers can help mount a new furnace if yours is beyond repair. An expert can also help you upgrade to a more energy-efficient model, like a heat pump. First, a skilled technician will assess your home's layout and heating needs. Then, the tech will recommend the best furnace model for your requirements and budget. HVAC technicians follow industry standards and safety protocols to ensure safe furnace replacement and connection. They also integrate a new system with existing air ducts and thermostats. After installation, the company does a final inspection to confirm that the furnace runs optimally and efficiently.


If you notice your furnace isn’t turning on, a furnace repair company will likely recommend a thorough inspection to identify possible issues. This will involve a technician examining each of the furnace's components. The inspection typically includes testing the thermostat's accuracy, checking for any gas or fuel leaks, inspecting the burner and ignition system, cleaning and replacing air filters, and examining the heat exchanger for cracks or damage. The technician verifies the heating system's safety and efficiency, making necessary adjustments or repairs. Regular yearly furnace tune-ups encourage peak performance, help prevent possible breakdowns, and promote safe living during cold winters.

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 malfunctions, breakdowns, and other safety concerns. Emergency services may cost more than scheduled services, but it's worth it to protect your health. If your furnace fails during extreme weather, and you're unable to open windows for fresh air, it can lead to serious discomfort and health risks due to the decreased indoor air quality.

Factors To Consider When Choosing a Local Union Furnace Repair Service

There are a number of important considerations for selecting a local Union furnace repair company. We’ve detailed them below.

  • Cost: Compare service offerings and prices among several Union furnace repair providers. Look for competitive and transparent pricing, but avoid extremely low-cost options. Companies that offer services for abnormally low prices may make up the difference by compromising the quality of work or materials.
  • Guarantees: Ask your furnace repair provider about any warranties or guarantees it offers. Trustworthy companies offer these guarantees to protect customers in case of any issues post-repair. Guarantees can cover both parts and workmanship.
  • Licensing: HVAC contractors in Ohio must obtain a contractor's license from the Ohio Construction Industry Licensing Board. Hiring a properly licensed and certified furnace repair provider is essential to ensure that your technician is qualified to handle furnace repairs safely and effectively.
  • Qualifications: Check into the qualifications and experience of a furnace repair company. Ideally, you want technicians that are well-trained and experienced at working with various furnace makes and models. Inquire about company training programs to verify that technicians are up to date on current industry standards.
  • 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.

How Much Does a Furnace Repair Cost?

Certain factors affect the price of repairing your furnace. These include the type of HVAC unit, extent of the damage, and cost of replacement parts. Furnace repair costs $417 on average, though prices vary depending on your situation. Below are some common furnace repairs and their average costs.

  • Broken thermostat: $78–$390
  • Cleaning: $47–$62
  • Cracked heat exchanger: $1,560–$2,730
  • Damaged blower bearings: $23–$117
