Maryland's Weather Puts Your HVAC to the Test

In Harford County, winter freezes and summer heatwaves aren’t just uncomfortable—they’re a serious test for your HVAC system. Without preparation, sudden weather swings can trigger breakdowns at the worst time. That’s why homeowners rely on Old Line Heating and Air to keep their systems ahead of the seasons. We know exactly what local systems need to stay efficient and reliable year-round.

What Happens During an HVAC Seasonal Inspection?

A seasonal inspection isn’t just a visual check. Our technicians perform a detailed diagnostic of your heating and cooling equipment. We test thermostat accuracy, inspect ductwork for leaks or blockages, examine electrical components, check refrigerant levels, clean evaporator coils, and confirm your blower motor and safety controls are working properly. It’s a proactive way to prevent surprise failures when the temperature swings.

When Should You Schedule Seasonal Maintenance?

We recommend booking HVAC maintenance twice a year—once in early spring and once in the fall. These pre-season tune-ups make sure your system is ready for the heavy demands of summer cooling and winter heating. Plus, catching issues early gives you time to fix them before they affect your comfort or drive up your energy bill.

Why Seasonal Maintenance Pays Off

The U.S. Department of Energy reports that well-maintained HVAC inspector use up to 15% less energy. That’s money back in your pocket every month—and fewer calls for emergency repairs. Our maintenance services also help preserve your system warranty and extend the lifespan of your equipment by years.
