Services Offered by Furnace Repair Companies

You can employ a local furnace repair provider for a number of services that help your furnace run efficiently. We review common services below.

Repair and Maintenance

Timely repairs extend the furnace's life span and optimize its energy efficiency, on top of restoring furnace function. Furnace repair experts can diagnose and fix most common furnace issues. These include malfunctioning thermostats, clogged air filters, or broken blower motors. Qualified HVAC technicians can also handle problems such as damaged heat exchangers, malfunctioning thermostats, possible gas leaks, and faulty ignitions. 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 properly.

Installation

HVAC companies can help you mount 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 home's layout and heating needs. Then, the tech will recommend the best furnace model for you based on your requirements and budget. Your HVAC technician can integrate a new system with existing thermostats and air ducts. They're trained to follow industry safety protocols and standards to ensure proper furnace replacement and connection. To ensure everything is running optimally, your technician will perform a final inspection following installation.

Inspection

If your furnace isn’t turning on, schedule a thorough inspection with a furnace repair provider. A technician will examine each of the furnace's components to look for potential issues. Inspections normally include inspecting the burner and ignition system, examining the heat exchanger for cracks or damage, cleaning and replacing air filters, checking for any gas or fuel leaks, and testing the thermostat's accuracy. Your technician will verify the heating system's efficiency and safety while making the necessary repairs or adjustments. Routine, annual furnace tune-ups encourage peak performance, help prevent potential breakdowns, and promote safe living during cold winters.

Emergency Services

Emergency furnace repair services are there to help with unexpected breakdowns, malfunctions, or safety concerns. Many companies offer these 24/7 services to get your system up and running promptly outside of normal business hours. When a furnace fails in extreme weather conditions, and it's not possible to open windows for fresh air, it can pose discomfort and serious health risks from decreased indoor air quality. Though emergency services will cost more than scheduled services, it’s worth it to protect your health.

Factors To Consider When Choosing a Local St. Clair Furnace Repair Service

There are multiple factors to consider when hiring a local St. Clair furnace repair company. We review some key considerations below.

  • Cost: We recommend comparing several St. Clair furnace repair providers to look for the best service offerings and prices. Look for transparent and competitive pricing, but avoid companies with extremely low rates. These providers often make up the difference with subpar replacement parts or low-quality workmanship.
  • Guarantees: Ask your furnace repair provider about any guarantees or warranties it offers. Reputable companies offer these guarantees to protect customers if any problems come up post-repair. Guarantees may cover both parts and workmanship.
  • Licensing: In Illinois, your HVAC contractor must obtain certification from your local city or municipal government. It's important to hire a furnace repair provider that is properly licensed and certified to ensure that your technician is trained and qualified to handle furnace repairs effectively and safely.
  • Qualifications: Find out what experience and qualifications a furnace repair company has. A company should employ technicians that are well-trained and have experience working with various furnace makes and models. You can inquire about a company's training policies to make sure they stay on top of the latest industry standard repair techniques.
  • Reputation and reviews: You can learn about a company's reputation by looking at online reviews and testimonials. A strong positive reputation is a good indicator of high-quality services. Look at how the provider addresses negative feedback or complaints, as this reflects its commitment to customer satisfaction.

How Much Does a Furnace Repair Cost?

The price of furnace repair varies depending on several factors, including extent of the damage, the HVAC unit type, and the price of replacement parts.

  • Broken thermostat: $81–$407
