Certified HVAC Services in Manassas, VA 20109 - Graham Mechanical Services

A full replacement with Graham Mechanical Services starts with a detailed assessment of your home's layout, insulation, and existing ductwork to ensure proper sizing and efficiency. We handle the removal of your old system and install a new, high-efficiency unit from brands like Carrier or Trane, including all necessary electrical and refrigerant connections. Our process prioritizes minimal disruption and includes testing the new system thoroughly to ensure optimal performance for our local climate, helping you manage energy costs year-round.

In Manassas homes, we often find issues like refrigerant leaks, faulty capacitors, or dirty condenser coils from seasonal pollen and debris. Our technicians perform a comprehensive diagnostic to pinpoint the problem, whether it's in the electrical components, airflow, or the compressor. We explain the repair clearly and use quality parts to restore your system's reliability, aiming for a fix that lasts through our humid summers and avoids recurring breakdowns.

Signs of dirty evaporator coils include reduced cooling, higher energy bills, and ice buildup on the refrigerant lines. Duct leaks often cause uneven room temperatures, dusty air, or a whistling sound from the vents. We inspect your system's coils during routine maintenance, cleaning them to restore efficiency. For duct leaks, we use specialized tools to locate breaches in your attic or crawlspace and seal them with mastic or metal tape, improving airflow and comfort while preventing energy loss common in our area's older homes.
