Fast, powerful heat when DMV winters hit hardest. Armada installs, repairs, and maintains gas furnaces of all makes and models — with licensed technicians, upfront pricing, and same day availability.
Natural gas furnaces remain the most popular heating choice for DC, Maryland, and Virginia homeowners — and for good reason. Gas heats faster, costs less to operate than electric resistance heating, and delivers powerful, consistent warmth even on the coldest winter nights.
Modern high efficiency gas furnaces achieve AFUE ratings of 96–99%, meaning nearly all of the fuel they consume is converted directly into heat for your home. With proper installation and regular maintenance, a quality gas furnace will keep your family comfortable for 20+ years.
From installing a brand new system to keeping your existing furnace running safely, Armada handles it all.
We size your system with a load calculation, help you choose the right efficiency tier, and install to manufacturer specs for full warranty coverage.
Upgrading your old system? We remove and dispose of your existing furnace and install your new unit — start to finish in a single day.
Ignitor failures, cracked heat exchangers, faulty gas valves, control board issues — we diagnose and fix all gas furnace problems quickly and safely.
Keep your furnace running safely and efficiently all winter. Our tune up covers burner cleaning, heat exchanger inspection, flue check, safety controls, and full performance test.
A cracked heat exchanger can release CO into your home without any odor or warning. We inspect and test for CO leaks as part of every maintenance visit.
Furnace out on the coldest night of the year? Armada's 24/7 emergency team serves DC, Maryland, and Virginia — fast response, any time.
Gas furnace problems can escalate quickly — and some involve serious safety risks. If you notice any of these signs, call Armada right away.
Your furnace runs but the air isn't warm — or barely warm. This often points to a failed ignitor, a faulty gas valve, or a tripped high limit switch that needs immediate diagnosis.
A healthy gas furnace burns with a steady blue flame. Yellow or orange flames indicate incomplete combustion — a potential sign of carbon monoxide production. Shut off and call us immediately.
Banging on startup usually means delayed ignition. Rattling suggests loose components. Squealing points to blower motor issues. Any new noise from your furnace deserves prompt attention.
Your furnace turns on and off repeatedly without completing a full heating cycle. This strains components and is often caused by a dirty filter, overheating heat exchanger, or faulty thermostat.
If your carbon monoxide detector triggers, evacuate immediately and call 911 — then call us. A cracked heat exchanger can leak odorless CO into your living space without any visible warning.
A sudden increase in your gas bill — with no change in usage — often means your furnace is losing efficiency due to dirty burners, a failing heat exchanger, or a system nearing the end of its life.
