Ignoring these requirements can result in fines, delays, and even the need to redo the work. Always work with a licensed and insured contractor who is familiar with local building codes.

Energy Efficiency

Virginia’s location in the Mid-Atlantic region means we experience a wide range of temperatures throughout the year. Choosing an energy-efficient HVAC system is crucial for managing energy costs and reducing your environmental impact.

• SEER2 Ratings: The higher the SEER2 rating, the more efficient the air conditioner or heat pump. Look for models with SEER2 ratings of 15 or higher to maximize energy savings. The minimum SEER2 rating for new AC units is 13.4 in the North and 14.3 in the South (which includes Virginia).
• HSPF Ratings: For heat pumps, the Heating Seasonal Performance Factor (HSPF) measures heating efficiency. Look for models with HSPF ratings of 8.0 or higher.
• ENERGY STAR: ENERGY STAR certified HVAC systems meet strict energy efficiency guidelines set by the EPA. Look for the ENERGY STAR label when shopping for a new system.
• Programmable Thermostats: A programmable thermostat allows you to set different temperatures for different times of the day, which can save you money on energy bills.

Virginia Energy Zones: While Virginia isn’t explicitly divided into stark energy zones like some states, the climate does vary. The coastal regions generally experience milder winters and more humid summers, making high-efficiency heat pumps with dehumidification features ideal. The western and northern parts of the state see colder winters, making dual-fuel systems a popular choice. Discuss the best options for your specific location with your HVAC contractor.
