Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. Howard County also had 2 tornado days in that period.

Maryland Licensing and Efficiency Rules
Maryland is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Maryland the company should carry a state license or registration. Ask for both.
Before You Hire
- Ask what the emergency fee is before the truck is sent.
- Keep space heaters away from curtains and bedding, and never heat the house with a gas oven.
- Maintenance plans often put members first in line for emergency calls.
