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.

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.

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 type of HVAC system is best for my home?

The best HVAC system for your home is unique to your situation, including your:
  • Climate: Heat pumps are generally more efficient in moderate climates, while furnaces are better for colder regions.
  • Budget: The upfront cost of different systems can vary significantly.
  • Energy Efficiency Goals: Higher-efficiency systems are usually more expensive upfront but result in lower energy bills over time.
  • Home Size and Layout: The square footage and layout of your home affect the system's capacity and ductwork requirements.
  • Existing Ductwork: If you have existing ductwork, you'll need a system compatible with it.
A qualified HVAC contractor can assess your needs and recommend the best heating and cooling system for your property.

What are the signs my air conditioner needs refrigerant?

Low refrigerant levels can cause various problems with your air conditioner:
  • Warm Air: The most noticeable sign is that the AC is blowing warm or lukewarm air.
  • Ice Buildup: Ice may form on the AC unit.
  • Increased Energy Bills: Your system has to work harder to cool, leading to higher energy consumption.
  • Hissing or Bubbling Sounds: These sounds can indicate a refrigerant leak.
If you suspect low refrigerant, contact an AC repair specialist to fix the leak and add refrigerant.
