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 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 not cool air.
  • Ice Buildup: Ice may form on the refrigerant lines or evaporator coil.
  • 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 HVAC technician to diagnose the issue and recharge the system.

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 is a ductless mini-split system?

A ductless mini-split system is a type of HVAC system that doesn't require ductwork. It consists of an outdoor unit (compressor/condenser) and one or more indoor units (air handlers) connected by refrigerant lines and electrical wiring. Each indoor unit cools or heats a specific zone or room, providing individual temperature control. Ductless mini-splits are more energy-efficient than traditional ducted systems and are a good option for homes where adding ductwork is impractical.
