Frequently Asked Questions About HVAC Companies

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

What is the best temperature to set my thermostat in summer?

The best temperature to set your thermostat in summer depends on your personal preferences and how much you’re willing to spend on energy costs. A general recommendation is to set your thermostat to 78°F (26°C) when you're home and awake. You can save energy by setting the thermostat higher when you're away or asleep.

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 could indicate 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 ductwork problems or an undersized/aging 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.

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.

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 diagnose the issue and recharge the system.
