Get answers to common questions about hvac services in Ellicott City, Maryland.
For a full system replacement in Ellicott City, homeowners can expect to pay between $5,000 and $12,000+, depending on system size, efficiency rating, and home specifics. Our humid summers and variable winters mean proper sizing is critical; an oversized or undersized unit will perform poorly. We recommend getting 3 detailed estimates that include a Manual J load calculation, which is especially important for Ellicott City's older, historic homes that may have unique insulation challenges.
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 contractors. Avoid calling during the first major heatwave or cold snap, as wait times will be longest.
Yes, Howard County requires a permit for the replacement of any gas furnace or central air conditioner, which your licensed contractor should handle. For rebates, always check with Baltimore Gas and Electric (BGE), which offers incentives for installing high-efficiency heat pumps and other qualifying equipment. Additionally, Maryland's state sales tax exemption for Energy Star products can provide savings on qualifying systems.
Always verify the contractor is licensed, insured, and holds a Maryland Home Improvement Commission (MHIC) license. Look for established local companies with strong reviews that are familiar with Ellicott City's diverse housing stock, from historic districts to newer developments. A trustworthy provider will perform an on-site evaluation, not give a phone quote, and will clearly explain their recommendations for your specific home's needs.
This is a common issue in our region due to high summer humidity. Often, the air conditioner is oversized, cooling the air quickly but not running long enough to properly dehumidify. Other causes include a aging system, ductwork leaks in unconditioned spaces like attics, or insufficient insulation. A professional assessment can identify the root cause, and solutions may include system recalibration, adding a whole-house dehumidifier, or duct sealing.
