Heating and air conditioning service built around Lorton
Nobody in Lorton wants to spend a day waiting on a technician with a four-hour window. We quote a 60-90 minutes target response time for this ZIP and hold crews locally so that number is realistic.
Local homeowners often run their system harder than the design intended, especially during May through September. That accelerates wear on contactors, capacitors and blower bearings.
We recommend two maintenance visits a year in Virginia: one before May through September and one before November through March. It is the single highest-return thing a homeowner can do for equipment life.

Lorton22079 HVAC questions, answered
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.
How much does an HVAC service call cost in 22079?
A diagnostic visit in Lorton 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.
Do you service commercial and light commercial properties?
Yes. Around Lorton we handle rooftop packaged units, split systems, VRF/VRV installations and building automation faults for offices, retail, restaurants and multi-tenant buildings, including after-hours scheduling so you are not disrupting trade.
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.
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 Lorton, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
Are your technicians licensed and insured?
Every technician dispatched into Lorton is licensed, insured and background-checked. We can provide proof of insurance on request before the visit if you would like it on file.
