Services Offered by Furnace Repair Companies

Furnace repair companies provide various services to ensure your furnace works effectively and efficiently. We review common services below.

Repair and Maintenance

Timely repairs restore your furnace's function, extend its life span, and optimize energy efficiency. Furnace repair providers can diagnose and fix a number of issues, including broken blower motors, malfunctioning thermostats, and clogged air filters. Qualified HVAC technicians are also experienced in tackling problems like possible gas leaks, faulty ignitions, malfunctioning thermostats, and damaged heat exchangers. Your furnace repair provider can also perform routine HVAC maintenance 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 help you install a new furnace. You might want a new system if yours is beyond repair or if you're looking for a more energy-efficient option such as a heat pump. Your technician first assesses your heating needs and home’s layout before recommending the best furnace model for your budget and home requirements. An HVAC professional can integrate your new system with existing thermostats and air ducts. They're trained on industry standards and safety protocols to ensure proper furnace replacement and connection. To ensure everything runs optimally, your technician will complete a final inspection after installation.


If you notice your furnace isn’t turning on, a furnace repair company will recommend a thorough inspection to identify potential problems. This process involves a technician examining each furnace component. Inspections usually include testing the thermostat's accuracy, inspecting the burner and ignition system, 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 safety and efficiency, making necessary repairs or adjustments. Regular yearly furnace tune-ups ensure optimal performance, help prevent possible breakdowns, and promote safe living during cold winters.

Emergency Services

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

Factors To Consider When Choosing a Local Lancaster Furnace Repair Service

You should consider several factors when hiring a local Lancaster furnace repair provider. We go over some important considerations below.

  • Cost: Look for transparent and competitive pricing, and make sure you find a company that offers all the services you need. Compare several Lancaster furnace repair companies. Avoid ones that offer extremely low rates, as many use subpar replacement parts and low-quality workmanship.
  • Guarantees: Ask your furnace repair company about the guarantees or warranties it offers. Trustworthy service providers offer these guarantees to protect customers in case of any issues post-repair. Guarantees can cover both parts and workmanship.
  • Licensing: In Pennsylvania, 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: Ask about the experience and qualifications of a furnace repair company. You want technicians that are trained and experienced in working on various furnace makes and models. Ask about a company's training programs to confirm that technicians are educated on the latest industry standards.
  • Reputation and reviews: Check online reviews and customer testimonials to learn more about a provider's reputation. Mostly positive reviews are indicative of quality services. You can also verify a company's commitment to customer satisfaction by seeing how it addresses negative feedback or complaints.

How Much Does a Furnace Repair Cost?

The cost of furnace repair depends on a number of factors, such as the extent of the damage, the HVAC unit type, and the price of replacement parts. The average furnace repair costs $451, but the final price depends on the situation. Below, find a list of common repairs and their costs.

  • Broken thermostat: $82–$411
