Heating and air conditioning service built around Dulles
Homeowners across Dulles call us when the system simply will not keep up. Humid tidewater summers and colder mountain winters mean equipment needs vary sharply across the state. That is why we staff a live dispatch line around the clock instead of routing you to a queue.
Because Virginia swings between seasons quickly, a lot of our Dulles calls come in the first hot or cold snap of the year — systems that sat idle for months and then get asked to run flat out.
The busiest week of our year in Dulles is the first stretch of sustained may weather. Systems that idled all season fail in clusters.

Dulles20189 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 Dulles 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.
What does a new system cost in Dulles?
A complete residential replacement in the 20189 area generally lands between $6,000 and $13,000 installed, depending on capacity, efficiency rating and how much ductwork has to be modified. We always perform a Manual J load calculation first, because an oversized unit costs more to buy and runs worse than a correctly sized one.
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in Dulles, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
Is my system low on refrigerant, or is it leaking?
Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.
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.
How much does an HVAC service call cost in 20189?
A diagnostic visit in Dulles typically runs $75 to $150, and that fee is usually applied toward the repair if you approve the work. Repair prices are quoted as a flat rate before we start, so the number you approve is the number you pay regardless of how long the job takes.
