What Are the Steps for AC Maintenance in Crofton, MD?

Maintaining your air conditioning system promotes comfort, improves energy efficiency, and helps your air conditioning unit stay in service longer. In Crofton, MD, where the summer heat can be intense during the cooling season, regular AC maintenance is an absolute must every year.

At Grove Heating & Cooling, our expert HVAC system technicians provide comprehensive annual air conditioner maintenance tune ups in Crofton, MD, designed to keep your AC running smoothly all season long. Here’s a detailed look at the AC maintenance checklist we follow and how each step benefits your AC unit.

1. Initial Inspection and System Evaluation

What We Do: Our technicians begin by conducting a thorough visual inspection of your entire AC system. This includes checking the outdoor condenser unit, indoor air handler, thermostat, and ductwork. They look for any visible signs of wear and tear, leaks, or other issues that might affect the performance of your system or signal the need for air conditioning replacement.


  • Early Problem Detection: Identifying potential problems early allows us to treat them now and prevent larger air conditioner repairs down the line.
  • Improved Safety: Ensuring all components are in good condition reduces the risk of hazards like refrigerant leaks.

2. Cleaning and Replacing the Air Filter

What We Do: The air filter is inspected and either cleaned or replaced during a routine maintenance visit. Clean filters are essential for maintaining good air quality and ensuring the efficiency of your AC system.


  • Enhanced Air Quality: Clean air filters trap dust, pollen, and other contaminants more effectively, improving the indoor air quality.
  • Efficiency Boost: Unclogged filters help the system run more efficiently, reducing energy consumption.

3. Checking and Cleaning Coils

What We Do: Both the evaporator coil inside and the condenser coil in the outdoor unit are checked and cleaned. Over time, the condenser and evaporator coils get covered in dirt and grime. This restricts heat exchange so you’ll have less cool air in your home.


  • Improved Cooling Efficiency: Clean coils facilitate better heat exchange, enhancing the cooling capacity of your AC unit.
  • Energy Savings: Efficient coils reduce the workload on the system, leading to lower energy bills.

4. Thermostat Calibration and Testing

What We Do: Technicians calibrate the thermostat to ensure it accurately reflects the temperature settings and functions correctly.


  • Optimal Comfort: A properly calibrated thermostat maintains your desired temperature settings.
  • Energy Efficiency: Accurate temperature readings prevent the system from overworking, saving energy.

5. Lubrication of Moving Parts

What We Do: The moving parts within the AC unit, such as the blower motor and fans, are lubricated to reduce friction and wear. Without these AC services, parts can sustain more wear and tear, driving up energy costs and leading to air conditioning repair issues.


  • Extended Lifespan: Lubrication minimizes stress, extending the life of the components.
  • Quieter Operation: Proper lubrication reduces noise from the AC unit.

6. Checking Refrigerant Levels

What We Do: Air conditioners rely on refrigerant, so technicians measure the refrigerant levels and ensure they are within the manufacturer’s specifications. We also check for leaks in the refrigerant lines If needed, we can arrange to repair leaks and add refrigerant to the system.


  • Optimal Performance: Correct refrigerant levels ensure the system removes heat from hot air efficiently.
  • Preventing Damage: Low refrigerant can cause the compressor to overheat and fail, so maintaining proper levels prevents costly repairs.

7. Inspecting Electrical Components

What We Do: The electrical connections, capacitors, and other components are inspected for wear and tear. Loose connections are tightened, and any damaged parts are replaced.


  • Safety Assurance: Properly maintained electrical components reduce the risk of electrical fires or malfunctions.
  • Reliable Operation: Ensuring the electrical system is in good condition helps prevent unexpected breakdowns.

8. Testing System Controls

What We Do: Technicians test the air conditioning unit controls during AC maintenance to ensure the unit cycles on and off correctly and responds appropriately to thermostat settings.


  • Consistent Performance: Properly functioning controls ensure your system operates reliably.
  • Energy Efficiency: Efficient cycling reduces unnecessary energy use and wear on the system.

9. Inspecting and Clearing Drain Lines

What We Do: Ensure the condensate drain line and drain pan are inspected and cleared of any blockages. These lines can become clogged with algae and debris over time.


  • Preventing Water Damage: Clear drain lines prevent water from backing up into your home and causing damage to your cooling system and its surroundings.
  • Maintaining Humidity Levels: Proper drainage helps maintain the right indoor humidity levels, contributing to overall comfort.

10. Reviewing System Performance and Providing Recommendations

What We Do: After completing all air conditioner maintenance tasks, technicians review the overall performance of the HVAC system and provide recommendations for any additional air conditioner repairs or improvements.


  • Comprehensive Understanding: Homeowners gain a clear understanding of their AC system’s condition.
  • Proactive Maintenance: Recommendations help address potential issues before they become major problems, ensuring the system remains in peak condition.
