What we do
From a failed capacitor to a full system replacement, Merrifield HVAC pros handle it all — AC, heating, air quality, residential and commercial.
Boilers last decades, but controls, circulators, and expansion tanks do not. In Merrifield, we diagnose boiler issues properly — combustion, water side, and controls — and repair only what is failing. Call (877) 317-0473, answered 24/7 in winter.
Want lower bills and fewer breakdowns? Twice-yearly HVAC maintenance in Merrifield keeps efficiency up and catches worn parts early. Plans and one-time tune-ups available — call (877) 317-0473 to schedule.
Blank screen, wrong readings, or a system that ignores the setpoint — Merrifield thermostat techs diagnose wiring, batteries, sensors, and compatibility, then repair or replace with a smart or programmable unit that actually fits your system.
High bills and uneven comfort usually have a findable cause. Our Merrifield energy audits test duct leakage, measure airflow room by room, and use thermal imaging to find where your heated and cooled air is escaping.
Not every warm-air complaint needs a new system. Our Merrifield AC repair techs test first — electrical, refrigerant charge, airflow, thermostat — and repair only what is actually failing. Free quote before any work begins.
A new AC is a 12–15 year decision. Our Merrifield 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.
Leaky, dirty ducts can waste 20–30% of your heating and cooling. Our Merrifield duct cleaning crews clean supply and return runs, then flag leaks and insulation gaps worth fixing — because clean ducts attached to leaky ones only go so far.
Dust, allergens, wildfire smoke, pet dander — Merrifield indoor air carries more than you think. We assess your home's air and install the right combination: high-MERV filtration, UV treatment, humidifiers, and dehumidifiers matched to your system.
