Get answers to common questions about hvac services in Merrifield, Virginia.
For a standard efficiency, properly sized system, full replacement costs in Merrifield typically range from $5,000 to $12,000, depending on the unit's capacity (tonnage/BTUs), efficiency rating (SEER/HSPF), and complexity of installation. Local factors like our humid summers and variable winters make proper sizing critical, and Fairfax County may require permits, which can add to the cost. Always get multiple detailed, written estimates from licensed local contractors.
The ideal times are during the shoulder seasons—early spring (March-April) before the intense summer heat and humidity arrive, and early fall (September-October) before winter. Scheduling during these periods ensures your system is ready for peak demand and provides much greater availability and potential for promotional pricing from local HVAC companies, unlike during a July heatwave or January cold snap when emergency service premiums apply.
Yes. Fairfax County requires a permit for the replacement of any gas furnace or central air conditioner, which your contractor should typically handle. Furthermore, Virginia residents may qualify for rebates from Dominion Energy for installing high-efficiency heat pumps or gas furnaces, and federal tax credits for certain ENERGY STAR® certified systems. A reputable local HVAC provider will be knowledgeable about these local incentives.
Prioritize contractors who are licensed by the Virginia Department of Professional and Occupational Regulation (DPOR), insured, and have strong local references. Look for companies with extensive experience serving Fairfax County's diverse housing stock, from older Dunn Loring homes to new Merrifield condos. Check for positive reviews on local platforms like Nextdoor and ensure they perform a detailed Manual J load calculation to correctly size your new system for our specific climate.
It can be normal during sustained periods of freezing temperatures, which we experience in Merrifield winters. 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 you notice a significant spike in your Dominion Energy bill, it could indicate low refrigerant, an undersized unit, or a failing auxiliary heat strip, warranting a professional diagnostic.
