For a standard system in a Sterling single-family home, full replacement typically ranges from $5,000 to $12,000. The final cost depends heavily on your home's size, the system's efficiency (SEER rating), and the complexity of the installation. Sterling's humid summers make a properly sized and efficient system crucial for comfort and energy savings, so investing in a quality installation from a reputable local contractor is key.
The ideal times are during the mild shoulder seasons of spring (March-April) and fall (September-October). Scheduling service before the intense summer heat and humidity arrives ensures your system is ready and helps you avoid the peak demand rush, which can lead to longer wait times and emergency service premiums. This timing is especially important in our climate to prevent a breakdown during a July heatwave.

Furthermore, you may qualify for rebates from Dominion Energy for installing high-efficiency heat pumps or air conditioners, and federal tax credits are available for qualifying ENERGY STAR® systems. Always ask your local HVAC provider about current incentives.
Prioritize contractors who are locally established, licensed, insured, and have strong community reviews.

Heat pumps work by extracting heat from the outside air, and as temperatures drop, they must run longer to maintain indoor comfort. However, if it's running non-stop without adequately heating your home or your energy bills are spiking, it could indicate an undersized system, low refrigerant, or another issue requiring professional diagnosis.
