When your furnace quits on a freezing Northern Virginia night, every hour matters. R.A. Dobson has kept Sterling-area homes warm since 1975, and our certified technicians track down heating problems fast — often the same day. We arrive on time, explain what went wrong in plain language, and give you an honest, upfront price before we touch a thing.
Whether your furnace is blowing cold air, cycling on and off, or has stopped altogether, we will find the cause and get your home comfortable again.
Our factory-trained technicians repair every major make and model, and most heating trouble comes down to a handful of familiar culprits:
• Furnace blowing cold or lukewarm air
• The system will not turn on at all
• Short cycling — turning on and off too often
• Loud banging, rattling, screeching, or booming on startup
• Weak airflow from the vents
• A yellow or flickering burner flame instead of steady blue
• Rooms that never reach the thermostat setting
• A sudden jump in your heating bill
• A burning or musty smell when the heat kicks on
Repair or replace? If your furnace is under 15 years old and has been well maintained, a repair is almost always the smart move. If it is older, needs frequent fixes, or struggles to keep up, we will honestly walk you through whether a repair or a new, more efficient system saves you more over the long run — with zero pressure. Ready to upgrade? See our furnace installation page.
