Frequently Asked Questions About HVAC Companies

What should I ask an HVAC technician during a service call?

When an HVAC technician comes for a service visit, ask these important questions:

• What is the source of the problem? Get a clear explanation of the issue and what caused it.
• What are my repair options? Discuss different repair solutions, if applicable, and their associated costs.
• Are there any preventative measures I can take? Find out if there are steps you can take to prevent future problems.
• Do you recommend a repair or replacement? If repairs are extensive or the system is old, consider replacement.
• What are the warranties on parts and labor? Understand the warranties before agreeing to any repairs.
• Do you have any customer reviews or testimonials I can check? Reputable HVAC technicians are often happy to provide references or direct you to customer reviews.

Asking these questions can help you make an informed decision and feel confident in the HVAC technician's expertise and recommendations.

What are the signs that I need a new HVAC system?

Several signs indicate it might be time for a new HVAC system:

• Frequent Repairs: If your system requires repairs frequently, it may be more cost-effective to replace it.
• Age of System: HVAC systems typically last 15-20 years. If your system is nearing or beyond that age, it's likely less efficient and more prone to breakdowns.
• Increased Energy Bills: A significant rise in energy bills might mean your system is losing efficiency and needs replacement.
• Uneven Temperatures: If some rooms are too hot or too cold, it could be a sign of an inefficient HVAC system.
• Poor Indoor Air Quality: If you're experiencing allergies, dust, or other indoor air quality issues, a new HVAC system with better filtration could help.
• Strange Noises or Smells: Unusual noises or foul odors emanating from your HVAC system could signal a problem that requires a system replacement.

If you're unsure whether you need a new system, contact a trusted HVAC technician for an assessment.

Should I repair or replace my old furnace?

Here are some factors to consider when deciding whether to repair or replace your furnace:

• Age: Furnaces typically last 15-20 years. If yours is significantly older, replacement is usually the better overall choice.
• Frequency and Cost of Repairs: If you've been having frequent or expensive repairs, replacing the furnace might be more cost-effective in the long run.
• Energy Efficiency: Newer furnaces are significantly more energy-efficient, which can lead to lower energy bills.
• Safety Concerns: Older furnaces can pose safety risks, such as carbon monoxide leaks. A new furnace offers enhanced safety features.

Consult with a reputable HVAC professional to assess your furnace and get recommendations.

What are the most common HVAC problems?

Common HVAC problems include:

• AC not cooling: Refrigerant leaks, compressor issues, or thermostat problems.
• Furnace not heating: Pilot light or ignition control issues, blower motor problems, or clogged filters.
• Uneven temperatures: Ductwork leaks, inadequate insulation, or faulty thermostats.
• Poor air quality: Dirty air filters, mold growth in ductwork, or inadequate ventilation.
• Strange noises: Unusual sounds from the system can indicate a variety of problems with different components.
• High energy bills: Inefficient systems, ductwork leaks, or improper thermostat settings.

If you're experiencing any of these issues, contact a qualified HVAC technician for diagnosis and repair.
