Services Offered by Furnace Repair Companies

Local furnace repair providers offer various services to keep your furnace running efficiently. We’ve outlined the most common ones below.

Repair and Maintenance

Timely professional repairs can restore your furnace's function, extend its life span, and optimize energy efficiency. Furnace repair experts can diagnose and repair most 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 properly.


HVAC companies can also install a new furnace if yours is beyond repair, or if you're planning on upgrading to a more energy-efficient model, like 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 budget and home requirements. Professional HVAC technicians follow industry standards and safety protocols for proper furnace replacement and connection. They can integrate your new system with your existing thermostat and air ducts. They'll complete a final inspection following installation to ensure your furnace runs optimally.


If your furnace isn’t turning on, you should schedule a thorough inspection through a furnace repair company. A technician will examine each component of your furnace to look for potential problems. The inspection typically includes inspecting the burner and ignition system, testing the thermostat's accuracy, 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 efficiency and safety while making the necessary repairs or adjustments. Regular yearly furnace tune-ups encourage peak performance, help prevent possible breakdowns, and promote a safe living environment during colder months.

Emergency Services

Emergency furnace repair services help restore your heat if your furnace breaks down on a cold 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 a scheduled service, but it's worth it to protect your health. If your furnace fails during extreme weather, and it's not possible to open windows for fresh air, it can lead to discomfort and serious health risks due to the decreased indoor air quality.

Factors To Consider When Choosing a Local Schertz Furnace Repair Service

You have a number of factors to consider when hiring a local Schertz furnace repair provider. We review some key considerations below.

  • Cost: Compare service offerings and prices among several Schertz furnace repair providers. Look for competitive and transparent pricing while avoiding extremely low-cost options. Companies that offer services for abnormally low prices may make up the difference by compromising material or workmanship quality.
  • Guarantees: Ask your furnace repair provider about the guarantees or warranties it offers. Trustworthy service providers offer these guarantees to protect customers in case of any issues post-repair. Guarantees may cover both parts and workmanship.
  • Licensing: Confirm that your furnace repair provider has all necessary licenses and certifications. This ensures that the technicians are qualified to handle furnace repairs safely and effectively. HVAC contractors in Texas must obtain a contractor's license from the Texas Department of Licensing & Regulation.
  • Qualifications: Look into a furnace repair company's qualifications and experience. A company should employ technicians that are well-trained and have experience 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: Check online testimonials and reviews to get a feel for a company's reputation. Generally positive feedback is indicative of quality services. You can also learn about a company's commitment to customer satisfaction by looking at how it addresses negative feedback or complaints.

How Much Does a Furnace Repair Cost?

The total cost of furnace repair will vary depending on factors including the type of HVAC unit you have, the extent of the damage, and the cost of replacement parts. The final total may vary, but on average expect to spend around $426 on furnace repair. Below are some common furnace repairs and their average costs.

  • Broken thermostat: $79–$396
