What is the Most Common AC Part to Repair in Crofton, MD?

When the summer heat hits Crofton, Maryland, the last thing you want is for your air conditioning system to break down. But AC units can encounter issues, and knowing the most common parts that might need repair can be helpful in case it happens to you.

Grove Heating & Cooling has been serving area homeowners for years, and we’re here to share our expertise on common problems affecting AC systems and what is the most common AC part to repair in Crofton.


Capacitors are a key component of your AC unit, helping start the compressor and fan motors. Over time, these parts can experience increased wear, leading to a malfunctioning air conditioner. Common signs of faulty capacitors include difficulty starting the air conditioning unit, frequent tripping of circuit breakers, and warm air blowing from the vents. If you experience any of these issues, it might be time to replace the capacitor to ensure your AC unit operates efficiently.

Refrigerant Lines

Refrigerant is crucial for cooling your home, and refrigerant leaks can cause significant problems. Low refrigerant levels can lead to your AC blowing warm air or not cooling your entire home adequately. The most common signs of refrigerant leaks include hissing noises and the inability to help your home stay cool. 

If you notice these symptoms, you’ll need professional HVAC system technicians to check for leaks and recharge the refrigerant. Grove can quickly diagnose and repair refrigerant line issues to restore your AC’s performance.

Condensate Drain Lines

As your air conditioner runs, it produces condensation that needs to be drained away. If the condensate drain line becomes clogged with dirt, algae, or debris, water can back up and overflow, causing water damage and potentially leading to mold growth. 

Common causes of clogged condensate drain lines include dirt, algae, and debris buildup. Regular inspection and cleaning of the condensate drain line can prevent these issues. The most common signs of a clogged condensate drain line include water pooling around your air conditioning unit. If you notice this, it’s time to call Grove for help as homeowners shouldn’t attempt this on their own.


Sometimes the problem isn’t with the AC unit itself but with the thermostat controlling it. A malfunctioning thermostat can cause the AC to cycle on and off erratically or fail to maintain the desired temperature, leading to a lack of cool air. Before assuming the worst, check if your thermostat is set correctly and replace the batteries. 

If the problem continues, it may need to be replaced. Grove’s HVAC technicians can assess whether your thermostat is functioning properly and replace it if necessary.

Evaporator Coils

Evaporator coils are responsible for absorbing heat from the air inside your home. If these coils freeze, they can’t do their job effectively, leading to poor cooling power. This usually happens due to restricted airflow caused by dirty air filters, blocked vents, or malfunctioning blower motors. To address this, turn off your AC to let the coils defrost, then replace any dirty air filters and ensure all vents are open. If freezing persists, Grove can identify and fix the underlying cause.
