Get answers to common questions about hvac services in Hanover, Maryland.
For a full system replacement in Hanover, homeowners can expect a typical range of $5,000 to $12,000+, depending heavily on system size, efficiency rating (SEER2/HSPF2), and brand. Maryland's humid climate often makes higher SEER2-rated systems (16+) a worthwhile investment for better dehumidification and long-term savings. Always ensure your quote includes proper load calculation for your home's size and Anne Arundel County's specific requirements, not just a rule-of-thumb estimate.
The ideal times are during the shoulder seasons—early spring (March-April) before AC demand hits and early fall (September-October) before heating season. Scheduling during these periods ensures greater technician availability and often leads to faster installation. Avoid the peak summer heatwaves and the first cold snaps of winter, as local HVAC companies are at their busiest and emergency calls can cause significant scheduling backups.
Yes. Anne Arundel County requires permits for new HVAC system installations and replacements, which a reputable contractor will handle. Maryland also has specific energy codes influencing system efficiency choices. Furthermore, check for available rebates from utilities like BG&E (Baltimore Gas and Electric), which often offer incentives for upgrading to high-efficiency heat pumps or air conditioners, providing direct savings to Hanover residents.
Look for a licensed, insured, and locally established company with strong reviews on platforms like Google and Nextdoor specific to Hanover/Glen Burnie. Verify they hold a Maryland Home Improvement Commission (MHIC) license. A trustworthy provider will perform a detailed Manual J load calculation for your home, offer clear written estimates, and discuss options suitable for our local climate's humidity and temperature swings.
Given our high summer humidity, a very common issue is a dirty or clogged evaporator coil, which hinders both cooling and dehumidification. Another frequent culprit is low refrigerant charge, often due to a slow leak, which drastically reduces efficiency. Regular spring maintenance that includes coil cleaning and a refrigerant check is crucial to prevent this problem during our most demanding weather.
