Get answers to common questions about hvac services in HHS, Maryland.
For a standard, single-family home in Howard County, a full system replacement typically ranges from $5,500 to $12,000+. This wide range depends on the system's efficiency (SEER rating), brand, home size, and complexity of installation. Maryland's climate, with hot, humid summers, makes a properly sized and efficient system crucial for comfort and energy savings, so investing in a higher SEER unit (16+) can be cost-effective long-term.
The optimal times are during the shoulder seasons of spring (March-May) and fall (September-November). Scheduling service before the intense summer heat and winter cold hits ensures your system is ready for peak demand and helps you avoid the highest service call wait times. For replacements, booking in spring or fall often provides more installer availability and potential off-season promotions from local contractors.
Yes. Howard County requires a building permit for the replacement of any HVAC equipment, which your licensed contractor should obtain. Furthermore, homeowners should check for available rebates from both the state of Maryland (through programs like EmPOWER Maryland) and local utilities like BGE, which offer incentives for upgrading to high-efficiency heat pumps, air conditioners, and furnaces, helping offset costs.
Always verify the contractor holds a Maryland Home Improvement Commission (MHIC) license and proper insurance. Seek out local companies with strong, long-standing reputations in the community, and read verified reviews. A trustworthy provider will perform a detailed load calculation (Manual J) for replacements, not just match the old unit's size, to account for your home's specific construction and our local climate.
It can be normal during sustained periods of freezing temperatures, which we experience in HHS. Heat pumps work harder as outdoor temps drop, and auxiliary electric heat strips will engage to supplement warmth, which can make the system run longer. However, if it's running non-stop without adequately heating your home or your energy bills are spiking, it could indicate an issue like low refrigerant, a failing component, or an undersized system that requires a professional diagnosis.
