Services Offered by Furnace Repair Companies

Furnace repair companies provide a number of services to ensure your furnace works effectively and efficiently. We’ve outlined the most common ones below.

Repair and Maintenance

Professional and timely repairs will restore your furnace's function, extend its life span, and optimize energy efficiency. Furnace repair companies can diagnose and repair any issues with your furnace, such as a clogged air filter, malfunctioning thermostat, or broken blower motor. Qualified HVAC technicians examine and fix individual problems such as faulty ignitions, possible gas leaks, malfunctioning thermostats, or damaged heat exchangers. Furnace experts can also perform routine HVAC maintenance to avoid unnecessary breakdowns. Regular maintenance involves inspecting and cleaning your furnace, lubricating moving parts, replacing air filters, and ensuring all components function correctly.


HVAC providers can help you install a new furnace if yours is beyond repair. An expert can also help you upgrade 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 budget and home requirements. HVAC technicians follow safety protocols and standards set by the industry to ensure safe furnace replacement and connection. They will also integrate a new system with existing thermostats and air ducts. After installation, the company completes a final inspection to ensure the furnace runs optimally.


If you notice your furnace isn’t turning on, a furnace repair company will probably recommend a thorough inspection to identify potential problems. This process involves a technician examining each component of your furnace. Inspections normally include testing the thermostat's accuracy, examining the heat exchanger for cracks or damage, checking for any gas or fuel leaks, inspecting the burner and ignition system, and cleaning and replacing air filters. Your technician will check the heating system's safety and efficiency and make any needed repairs or adjustments. Annual furnace inspections and tune-ups encourage optimal performance and help prevent breakdowns, which promotes a safe living environment during colder months.

Emergency Services

Some furnace repair providers also have emergency services. These services are available 24/7 for unexpected malfunctions, breakdowns, or other safety concerns. If your furnace breaks down during a cold night, emergency services can get it up and running again as quickly as possible. Furnace failure can cause serious discomfort and health risks from the decreased indoor air quality, especially if it breaks down during extreme weather and it's not possible to open windows for fresh air. Emergency services might cost more than a scheduled service, but it's worth it to protect your health.

Factors To Consider When Choosing a Local Cary Furnace Repair Service

There are several important considerations for hiring a local Cary furnace repair service. We’ve detailed them below.

  • Cost: Look for transparent and competitive pricing, and make sure you find a company that offers all the services you need. We recommend comparing multiple Cary furnace repair providers. Avoid ones with extremely low rates, as they may employ low-quality workmanship or subpar replacement parts.
  • Guarantees: Reputable furnace repair companies should provide warranties or guarantees on their parts and workmanship. Companies that stand behind their work offer you peace of mind if something goes wrong post-repair.
  • Licensing: You want to use a furnace repair provider that holds all the required licenses and certifications. HVAC contractors in North Carolina must obtain a contractor's license from the New Mexico Regulation and Licensing Department Construction Industries Division. Proper licensing helps ensure that technicians are qualified to safely handle furnace repairs.
  • Qualifications: Look into a furnace repair company's qualifications and experience. Ideally, technicians will have appropriate training and expertise in various furnace makes and models. You can ask about ongoing training programs to ensure a company is up to date with current repair techniques.
  • Reputation and reviews: Check online testimonials and reviews from previous customers to learn about a company's reputation. Look for a provider with overall positive reviews, but also pay attention to how it addresses negative reviews and complaints. This can reveal a lot about a provider's commitment to customer service.

How Much Does a Furnace Repair Cost?

Certain factors affect the cost of furnace repair. These include the type of HVAC unit, extent of the damage, and price of replacement parts. Furnace repair costs $442 on average, though prices vary depending on your situation. Below are some common furnace repairs and their average costs.

  • Broken thermostat: $81–$405
  • Cleaning: $49–$65
  • Cracked heat exchanger: $1,621–$2,837
  • Damaged blower bearings: $24–$122
  • Damaged blower belt: $24–$89
  • Filter change: $32–$122
