  • Experience: Choose a contractor with extensive experience in the HVAC industry, especially in the type of service you need.
  • Licensing and Insurance: Verify that the contractor is properly licensed and insured.
  • Certifications: Look for NATE (North American Technician Excellence) certification, which indicates a high level of technical competency.

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. Consider a programmable thermostat that allows you to automatically adjust the temperature based on your schedule.

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 different types of HVAC systems?

Several types of HVAC systems are available for residential and commercial buildings:
  • Split Systems: The most common type, consisting of an outdoor unit (condenser/compressor) and an indoor unit (air handler/furnace).
  • Heat Pumps: Provide both heating and cooling by transferring heat between indoor and outdoor air.
  • Ductless Mini-Splits: Ideal for homes without existing ductwork or for adding heating and cooling to specific zones.
  • Packaged Units: A single unit that contains all the system's components.
  • Geothermal Heat Pumps: Use the earth's stable temperature to provide highly efficient heating and cooling.
An HVAC professional can help determine the best type of system for your needs and budget.

  • Experience: Choose a contractor with extensive experience in the HVAC industry, especially in the type of service you need.
