There are many benefits to upgrading your cooling system, including:

  • Increased comfort – You deserve to be comfortable when you enter your home, after all, it is your home! An old air conditioner may not provide the comfort you’re looking for. A new air conditioner can provide a cool relief to the hot, humid days Maryland homeowners are accustomed to.
  • Increased energy efficiency – One sign it may be time to install a new air conditioner in your home is increased utility costs. New, energy-efficient AC units can provide increased comfort while lowering your energy bills.
  • Proper sizing – Even if your old air conditioner is not failing, high energy bills and low cooling capacity could indicate that it isn’t sized properly for your home. An air conditioner that is too small or too large for your home won’t cool your space efficiently. It also costs more to operate because your AC must work harder to achieve indoor comfort. An improperly sized AC unit is also more likely to break under this added stress, requiring more frequent air conditioning repairs and costing you more money.

Signs You Need Air Conditioning Repair

Getting prompt repair for your air conditioner is key to protecting your family and your comfort. Thankfully, there are often signs that your air conditioner needs to be repaired that happen before the system breaks down completely. Here are some common signs to look for to determine if you should call GAC Services for AC repair:

  • Your air conditioner doesn’t cycle on or off. Air conditioners are a significant investment in your Maryland home. It’s best to leave any repairs or maintenance to a licensed HVAC professional, like us!
  • Your energy bills have increased. If you notice your energy bills are higher than usual, it could be a sign that your air conditioner is working for longer periods of time as an attempt to cool your home—often the result of a broken system.
  • Your registers are dispensing warm or hot air. If you notice your registers dispensing warm or hot air into a room, it could be the result of a clogged air filter, an issue with its condenser or compressor, or a refrigerant problem. To determine the exact cause, an HVAC professional should inspect your Maryland cooling system.
  • Your air conditioner makes loud or strange noises. The cause of your air conditioner making loud or strange noises can be a variety of issues—including its compressor, drive motor, fan blade, electrical connections, and more—and requires an HVAC technician to diagnose and repair.
  • Your air conditioner’s coils are frozen. Often caused by a dirty AC filter, frozen air conditioner coils may be the result of a coolant leak.
  • Your air conditioner is leaking. Don’t wait to call if your air conditioner is leaking fluid from the outdoor unit. If you notice your air conditioner is leaking moisture into your house, our friendly technician will inspect your condensation pan and drainage pipes to clean or replace them if necessary. Moisture in your home caused by a broken AC exposes you and your family to mold, mildew, and/or water damage.
  • You notice inconsistent temperatures in your home. Inconsistent temperatures are often the first sign of a broken air conditioner. If you notice some rooms are warmer than others or significant temperature changes within your household, contact a cooling professional.

If you are noticing these problems, call (240) 233-8498 for Columbia, MD air conditioning repair from a family-owned and operated local company.

Air Conditioner Maintenance & Tune-Up Service

One of the best ways to avoid the need for AC repair is with proper maintenance. If your system is maintained annually by a qualified HVAC technician, you have a far lower risk of a breakdown. At a maintenance appointment, your technician will check your system thoroughly for any signs of a breakdown, giving you the chance to address these issues before you have a problem. You will also have your system cleaned and optimized, giving you greater function throughout the cooling season.

Air conditioner maintenance helps:

  • Improve the life span of your air conditioner
  • Prevent breakdowns
  • Reduce the need for future repairs
  • Improve the energy efficiency of your cooling system
  • And more!

If you are in need of an AC maintenance check in Columbia, make an appointment by calling GAC Services at (240) 233-8498.
