FAQs

Will I know the cost before you start?
Yes. Before any repair or installation begins, we diagnose the issue and give you a clear price, so you’re approving a number, not a guess. There’s no surprise line item added after the work is done, and if we find something additional during the job, we’ll walk you through it and get approval before touching it.

Should I repair or replace my system?
It depends on two things: age and repair cost. As a rule of thumb, if your system is past 10 years old and the repair cost is approaching half the price of a new unit, replacement is usually the better long-term value — you’re paying to patch equipment that’s likely to need another repair soon anyway. Under that threshold, repair is almost always the right call. We’ll lay out both the repair estimate and a replacement quote side by side so you can compare real numbers instead of guessing.

Are there extra charges for evenings, weekends, or emergencies?
No overtime surcharges. Emergency service costs the same whether it’s 2pm on a Tuesday or 2am on a Sunday — the price you’re quoted is the price you pay, regardless of when you call.

Why is my house humid even with the AC running?
McLean sits close to the Potomac and several of its tributaries, which keeps summer dew points elevated even on days that don’t feel unusually hot. An AC system’s main job is temperature, but humidity removal depends on runtime and proper sizing — a unit that’s oversized will cool the air quickly and shut off before it’s pulled enough moisture out, leaving the house feeling damp. Undersized or aging systems have the opposite problem: they run constantly but still can’t keep up. Correct sizing, a clean filter, and adequate refrigerant charge are what actually fix this, not just lowering the thermostat.

Why is my AC freezing up during a heat wave?
Ice on the indoor coil almost always traces back to restricted airflow or low refrigerant. A dirty air filter or blocked return vent chokes off airflow, and once the coil gets too cold, moisture in the air freezes onto it — which then blocks airflow even further, worsening the cycle. Low refrigerant does something similar by dropping coil temperature below where it should be. Running the system hard during a heat wave accelerates both problems, so what might’ve been a minor issue in spring becomes a full shutdown in August.

Why are some rooms hot and others cold?
This is common in McLean’s older homes, where ductwork was often sized and routed for a smaller or different system than what’s running today. Leaky duct joints, closed or blocked vents, and unbalanced airflow between floors are the usual culprits — the system is producing the right amount of conditioned air, it’s just not getting distributed evenly. A duct evaluation typically identifies exactly where the imbalance is coming from.

How fast can a technician get here?
We dispatch the same day for most McLean service calls, and our trucks carry the parts needed for the majority of repairs, so a technician can typically diagnose and fix the problem in a single visit rather than needing to reschedule for parts.

What counts as an AC or heating emergency?
Total loss of heating or cooling in extreme weather, a burning smell coming from the system, or water leaking near electrical components all warrant an immediate call rather than waiting for a routine appointment. Any of these can escalate into a bigger repair — or a safety issue — the longer they’re left alone.

Is the repair backed by a warranty?
Yes. All workmanship is covered, meaning if something isn’t right after we’ve completed a repair or installation, we come back and make it right at no additional charge.
