No heat, weak heat, or a furnace that will not stay lit — our Annandale furnace repair techs find the fault fast: igniters, flame sensors, blower motors, gas valves, and thermostats. Winter in Annandale is no time to wait.
Mini-splits are heat pumps, so they heat and cool — and each indoor head is its own zone. Our Annandale installers size and place heads for even comfort, run clean line sets, and set up the controls. Free quotes at (877) 317-0473.
Spring AC tune-up, fall furnace tune-up — the two visits that prevent most breakdowns. Our Annandale seasonal service covers cleaning, electrical and refrigerant checks, safety controls, and airflow testing in one thorough visit.
No cooling in a heat wave or no heat in a freeze is an emergency — full stop. Our Annandale emergency HVAC line is answered 24/7, with techs dispatched around the clock for no-heat and no-cool calls.
An AC breakdown in Annandale heat is an emergency, not an inconvenience. We dispatch Annandale air conditioning repair techs with stocked trucks: capacitors, contactors, refrigerant, and the tools to find leaks fast. Call (877) 317-0473 — we answer 24/7.
A new AC is a 12–15 year decision. Our Annandale installation crews size by Manual J calculation, not rule of thumb, and set up airflow and charge correctly — the details that separate a system that lasts from one that limps.
High bills and uneven comfort usually have a findable cause. Our Annandale energy audits test duct leakage, measure airflow room by room, and use thermal imaging to find where your heated and cooled air is escaping.
