Heater Repair in Manassas, VA

A dead heater in January feels very different in a drafty older home near Old Town than in a tight new build off Liberia Avenue — but neither one is something to sit with. Northern Virginia winters bring stretches of genuinely freezing weather, and a house without heat loses ground fast. Standard Air Heating and Air Conditioning has repaired furnaces, heat pumps, and hybrid systems across Manassas and Manassas Park for more than 30 years, and we know the failure patterns of both the older housing stock and the newer developments.

Our approach is the same one that earned us a 4.9-star rating on Google: diagnose carefully, explain honestly, price clearly, and repair whenever repair is the right answer. If your heat is out right now, call 571-781-4700 — we offer 24/7 weekend emergency service, because heating failures don't check the calendar.

Furnace and heat pump problems we fix in Manassas

In older Manassas homes, gas furnaces dominate, and their common failures are familiar: ignitors and flame sensors that fail with age, blower motors straining against ductwork that was retrofitted into the house, and short cycling from overheating when filters go too long between changes. Newer neighborhoods lean more on heat pumps, which bring their own winter issues — outdoor units icing over beyond the normal defrost cycle, auxiliary heat running constantly and inflating electric bills, and control boards that fail quietly until the first cold snap exposes them. We service all major brands of both.

Before you call: two quick checks

We'd rather save you a service call than bill one. Before you pick up the phone, check that your thermostat is set to heat with the fan on auto, and check your filter — a badly clogged filter can shut a furnace down on its high-limit switch and mimic a serious failure. If those check out and you have gas heat, confirm other gas appliances are working. Still no heat? That's when you call us. And if you ever smell gas, leave the house first, call the gas company, and then call us to handle the repair.

Repair-first, with a straight answer on replacement

Plenty of Manassas homes are still heated by furnaces well into their second decade, and many are worth keeping alive. A flame sensor, ignitor, or capacitor is a routine fix. But some findings change the math — a cracked heat exchanger is a safety issue, not a repair candidate, and a heat pump compressor failure on an aging system rarely justifies the cost. When we hit one of those, we say so plainly, give you a free estimate for replacement, and let you make the call without pressure. That's how we've done business for 30 years.
