A homeowner’s guide to summer HVAC maintenance in Western North Carolina

ASHEVILLE, N.C. (828newsNOW) — Summer in Western North Carolina can bring warm afternoons, humid evenings and quick changes in weather, making a reliable cooling system important for home comfort.

At MB HAYNES, seasonal maintenance can help homeowners spot small issues before they become larger problems. While some HVAC work should always be handled by a trained professional, there are simple steps homeowners can take to help their cooling system perform better through the summer months.

Check your air filter during cooling season

One of the easiest maintenance steps is also one of the most important: checking the air filter.

A dirty or clogged filter can restrict airflow and make an HVAC system work harder to move cool air through the home. That can affect comfort, efficiency and overall system performance.

How often a filter should be changed depends on the home, the type of filter, whether pets are present and how often the system runs. During peak cooling season, homeowners should check the filter regularly and replace it when it appears dirty.

Keep HVAC vents and air returns clear

Blocked vents and air returns can make it harder for a cooling system to circulate air properly.

Furniture, rugs, curtains and household items can restrict airflow without homeowners realizing it. Walk through the home and make sure supply vents and return grilles are open and unobstructed.

If one room stays warmer than the rest of the house, airflow could be a problem. Uneven cooling can sometimes be related to blocked vents, but it may also point to ductwork issues, poor insulation or a system that needs professional attention.

Clear debris around the outdoor AC unit

Your outdoor AC unit needs space to breathe.

Grass clippings, leaves, weeds and storm debris can collect around the unit and affect airflow. Homeowners can help by keeping the area around the unit clear and trimming back vegetation.

Be careful not to damage the equipment, and avoid opening the unit or attempting electrical or refrigerant-related repairs. Those tasks should be left to an HVAC professional.

 After storms, visually check the outdoor unit for fallen branches or debris.

Watch for indoor humidity problems

Air conditioning does more than lower the temperature. It also helps manage indoor humidity.

If your home feels damp, sticky or uncomfortable even when the air conditioner is running, your system may not be performing as it should.

High indoor humidity can be caused by poor airflow, dirty components, low refrigerant, ductwork problems or equipment that is not properly sized for the home.

Listen for unusual HVAC noises

New or unusual sounds should not be ignored.

Rattling, buzzing, grinding, squealing or banging may point to loose parts, motor problems, electrical issues or other mechanical concerns. Short cycling, when the system turns on and off frequently, can also be a warning sign that the system needs attention.

Schedule professional HVAC service before peak summer heat

A professional maintenance visit can help identify problems homeowners may not see.

During a service appointment, an HVAC technician can inspect key components, check system performance, look for signs of wear and make sure the system is operating safely and efficiently.
