Professional HVAC Repair in Arlington, VA 22201 - J W Garris Air Conditioning & Heating

Common signs in our local climate include the system getting stuck in one mode (only heating or only cooling), reduced heating or cooling capacity, or strange hissing noises from the outdoor unit. Since Arlington experiences both hot summers and cold winters, a faulty valve prevents efficient switching, leading to discomfort and higher energy bills. Our technicians can diagnose and repair this specific issue to restore your system's full functionality.

Uneven temperatures are a frequent issue in Arlington homes and are often due to restricted airflow, leaky or poorly insulated ductwork, or an improperly sized HVAC system. It can also be caused by a single-zone thermostat struggling with sun exposure or multiple floors. We perform detailed airflow and duct inspections to pinpoint the cause—whether it's a blocked vent in a bedroom or a leak in the attic—and provide targeted solutions like duct sealing, balancing, or system adjustments.

First, check your air filter; a clogged filter is a common culprit for reduced airflow and system strain. Next, ensure all vents are open and unblocked by furniture or curtains. Also, verify your thermostat settings are correct for the season. If problems like uneven cooling or a heat pump not switching modes persist, it's time to call for professional help. Lingering issues often indicate mechanical failures or duct problems that require expert diagnosis from a local technician familiar with Arlington's housing styles and climate demands.
