About HVAC service in Lorton
Homes in Fairfax County tend to be a mix of older builds with original ductwork and newer infill construction, which means airflow problems show up very differently from one street to the next.

Lorton HVAC questions, answered
What causes water to leak from the indoor unit?
Almost always a blocked condensate drain line, a failed drain pan float switch, or a frozen coil melting faster than the pan can handle. In Lorton we see algae and dust clogging drain lines constantly during May through September. It is a fast fix but ignoring it ends in ceiling damage.
Why is my system short cycling?
Short cycling in Lorton most often comes from a restricted airflow path — a loaded filter, a closed register, an undersized return — or from an oversized unit. It can also be a failing flame sensor or a pressure switch fault. We measure static pressure and temperature rise before concluding anything, because guessing at this one is expensive.
Do you offer maintenance plans?
We do. A two-visit plan in Virginia covers a spring cooling inspection and an autumn heating inspection, priority scheduling during peak weeks, discounted repairs and no diagnostic fee. Members rarely end up on the emergency list.
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in Lorton see most often — but a firm price needs eyes on the equipment. Any company that quotes a final number without seeing the unit is usually quoting low to get through the door.
How often should I change my filter in 22079?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in Lorton with pets, ongoing construction nearby, or a high-MERV filter in an undersized return should move to monthly changes. A loaded filter is the single most common cause of frozen coils and failed blower motors.
