Services Offered by Furnace Repair Companies

Your local furnace repair provider will offer various services to ensure your furnace runs efficiently. We outline some common offerings below.

Repair and Maintenance

Timely repairs not only restore your furnace's function, they also extend its lifespan and optimize energy efficiency. Furnace repair experts are trained to handle broken blower motors, clogged air filters, malfunctioning thermostats, and more. Your technician can help diagnose and repair problems like these to keep your furnace running efficiently. A qualified HVAC technician can also help with issues like possible gas leaks, damaged heat exchangers, malfunctioning thermostats, or faulty ignitions. Furnace repair professionals can also provide a routine HVAC system tune-up to avoid unnecessary breakdowns. This can involve inspecting and cleaning your furnace, replacing air filters, lubricating moving parts, and ensuring all components function properly.

Installation

HVAC companies can also help you set up a new furnace. You may need a new system if yours is past repair or if you want to upgrade to a more energy-efficient option such as a heat pump. Your technician first assesses your home's layout and heating needs before recommending the right furnace model for your requirements and budget. HVAC technicians follow industry standards and safety protocols to ensure correct furnace replacement and connection. They will also integrate your new system with existing thermostats and air ducts. After installation, the company performs a final inspection to confirm that the furnace runs optimally and efficiently.

Inspection

Schedule an inspection through a furnace repair company if you notice your furnace failing to turn on. During the inspection, a technician will look at each of the furnace's components to identify potential issues. Inspections normally include examining the heat exchanger for cracks or damage, cleaning and replacing air filters, inspecting the burner and ignition system, checking for any gas or fuel leaks, and testing the thermostat's accuracy. The technician verifies the heating system's efficiency and safety while making the necessary repairs or adjustments. Routine, annual furnace tune-ups ensure optimal performance, help prevent possible breakdowns, and promote a safe living environment during colder months.

Emergency Services

If your furnace breaks down in winter, some furnace repair companies provide emergency repair services to get your system up and running as soon as possible. These services are available 24/7 for unexpected malfunctions, breakdowns, and other safety concerns outside regular business hours. Emergency services may be more expensive than a scheduled service, but protecting your health is worth it. Furnace failure can lead to discomfort and serious health risks from decreased indoor air quality, especially if it breaks down during extreme weather conditions when you can't open windows for fresh air.

Factors To Consider When Choosing a Local Altadena Furnace Repair Service

There are a number of important considerations for choosing a local Altadena furnace repair provider. We go over some important factors below.

  • Cost: We recommend comparing several Altadena furnace repair providers to look for the best prices and service offerings. Look for competitive, transparent pricing, but be wary of companies that offer extremely low rates. These providers often make up the difference with low-quality workmanship or subpar replacement parts.
  • Guarantees: Warranties and guarantees offer you peace of mind if issues arise post-repair. Trustworthy furnace repair companies should stand behind their work with warranties or guarantees for both workmanship and replacement parts.
  • Licensing: Make sure your furnace repair company holds the licenses and certifications required by local and state authorities. Proper licensing ensures technicians are qualified and trained to handle furnace repairs safely and effectively. HVAC contractors in California must obtain a contractor's license from the Contractors State License Board.
  • Qualifications: Ask about the qualifications and experience of a furnace repair company. Ideally, you want technicians that are well-trained and experienced at working with various furnace makes and models. Ask about a company's training programs to confirm that technicians are educated on the latest industry standards for repairs.
  • Reputation and reviews: Customer testimonials and other online reviews can give you an idea of a provider's reputation and commitment to customer satisfaction. Choose a company with overall positive reviews, and pay attention to the way it addresses complaints and negative feedback.
