Frequently Asked Questions About HVAC Companies

Find answers to common questions about HVAC services, finding contractors, and getting the best HVAC systems for your needs.

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

How long does an HVAC system last?

The average lifespan of an HVAC system is about 15-20 years. However, how long your system lasts can vary depending on usage, maintenance, and the system's quality. Proper maintenance can help your system last longer. An older system is likely to be less efficient and more prone to repairs.

How do I choose the right size AC unit for my home?

Choosing the right AC unit size is essential for efficient cooling. An undersized unit won’t cool your home adequately, while an oversized unit will cycle on and off frequently, wasting energy and leading to premature wear and tear. A qualified HVAC technician will calculate the appropriate size AC unit for your home based on factors like:
  • Your home's square footage
  • Your local climate
  • Insulation levels
  • Window efficiency
  • Number of occupants
This calculation involves determining your home's cooling load, typically measured in BTUs (British Thermal Units). Don’t rely on estimates or guesswork; consult with an HVAC professional to ensure your new AC unit is properly sized for your specific needs.
