Services Offered by Furnace Repair Companies

Your local furnace repair company provides a number of services to help your system work efficiently and effectively. We’ve outlined the most common ones below.

Repair and Maintenance

A timely repair restores the furnace's function, extends its life span, and optimizes energy efficiency. Furnace repair providers can diagnose and fix a number of common furnace issues. These include clogged air filters, malfunctioning thermostats, or broken blower motors. Qualified HVAC technicians can also handle problems such as malfunctioning thermostats, faulty ignitions, damaged heat exchangers, and possible gas leaks. Your furnace repair professional can also perform routine HVAC system upkeep to help avoid unnecessary breakdowns. Your technician will make sure all components function properly by inspecting your furnace, cleaning it, replacing air filters, and lubricating moving parts.


HVAC companies can also install a new furnace if your furnace is beyond repair, or if you're planning on upgrading to a more energy-efficient model, such as a heat pump. Skilled technicians will first assess your heating needs and home’s layout. Then, they recommend a suitable furnace model based on your requirements and budget. Your HVAC technician can integrate your new system with your existing thermostat and air ducts. They're trained on industry safety protocols and standards for proper exchange of the existing furnace and connection. Following installation, the technician will complete one last inspection to ensure your furnace runs properly.


If you notice your furnace isn’t turning on, your furnace repair company will probably recommend a thorough inspection to identify possible issues. This will involve a technician examining each of the furnace's components. Inspections typically include examining the heat exchanger for cracks or damage, cleaning and replacing air filters, testing the thermostat's accuracy, inspecting the burner and ignition system, and checking for any gas or fuel leaks. A technician will check the heating system's efficiency and safety and make any necessary repairs or adjustments. Yearly furnace tune-ups help ensure optimal performance and help avoid 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 breakdowns, malfunctions, or other safety concerns. If your furnace breaks down during a cold night, emergency services can have it up and running again as soon as possible. When your furnace fails during extreme weather, and it's not possible to open windows for fresh air, it can pose serious discomfort and health risks due to decreased indoor air quality. Though emergency services will cost more than scheduled services, protecting your health is worth it.

Factors To Consider When Choosing a Local Simi Valley Furnace Repair Service

You should consider a number of factors when hiring a local Simi Valley furnace repair service. We’ve detailed them below.

  • Cost: Compare service offerings and prices among several Simi Valley 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 material or workmanship quality.
  • Guarantees: Reputable furnace repair providers should offer guarantees or warranties on their workmanship and parts. Providers that stand behind their work offer you peace of mind should something go wrong post-repair.
  • Licensing: Verify that your furnace repair servicer holds all necessary licenses and certifications. This ensures that its technicians are qualified to handle furnace repairs safely and effectively. HVAC contractors in California must obtain a contractor's license from the Contractors State License Board.
  • Qualifications: Inquire about a company's training policies and its technicians' experience. Companies that offer ongoing training tend to have technicians that are up to date on the latest repair techniques. You want a company that employs well-trained technicians who are experienced in working with various furnace makes and models.
  • Reputation and reviews: Research the company's reputation by reading online reviews and testimonials from previous customers. A strong positive reputation is a good indicator of high-quality services. Look at how a provider addresses complaints or negative feedback, reflecting its commitment to customer satisfaction.

How Much Does a Furnace Repair Cost?

Several factors influence the price of your furnace repair project. These include the type of HVAC unit, extent of the damage, and price of replacement parts. On average, furnace repair costs $446, although prices vary depending on your situation. The following are some common furnace repairs, as well as their average costs.

  • Broken thermostat: $81–$407
  • Cleaning: $49–$65
  • Cracked heat exchanger: $1,629–$2,851
  • Damaged blower bearings: $24–$122
  • Damaged blower belt: $24–$90
  • Filter change: $33–$122
