Why Schedule Heating Maintenance Now
Northern Virginia winters hit hard, and your system is about to run nonstop for months. Scheduling maintenance ahead of peak season ensures your heater is ready before you need it most. Last-minute breakdowns often mean long wait times for service—especially during January cold snaps—so a pre-season tune-up is the smartest way to stay ahead of problems.
Benefits of Professional Heating Tune-Ups
Fewer Breakdowns / Repairs
Most mid-season failures we see could have been prevented. By tightening connections, cleaning components, and testing safety controls, our technicians catch problems before they leave your family without heat.
Lower Energy Bills
A clean, calibrated system works more efficiently. That means your furnace or heat pump produces the same comfort while using less energy—a major benefit in Northern Virginia where systems run constantly during peak cold spells.
Extended System Lifespan
Your heating system represents one of the biggest investments in your home. Regular maintenance protects that investment, often adding 5–10 years to a furnace or heat pump’s usable life compared to neglected systems.
Better Indoor Air Quality
Dust, debris, and soot inside your heating system get blown through your ducts and into your home. Tune-ups remove buildup, swap filters, and ensure your system is circulating clean, healthy air.
Safer Operation
Old or neglected systems can develop issues like cracked heat exchangers or gas line leaks. Our technicians test for carbon monoxide, gas pressure problems, and electrical faults to keep your family safe.
Once your system is maintained, you’ll immediately see the difference: lower bills from improved efficiency, fewer costly repairs, cleaner indoor air, and peace of mind knowing your family is safe and warm. A single tune-up can add years to your system’s lifespan while cutting down on day-to-day stress.
What’s Included in Our Heating Maintenance Service
Every tune-up is designed to keep your system efficient, safe, and ready for heavy winter use. Our comprehensive checklist includes:
Complete System Inspection
We carefully inspect the furnace, boiler, or heat pump for wear, leaks, and early warning signs. That includes checking heat exchangers, burners, flues, and electrical components.
Deep Cleaning of Critical Components
Our technicians remove dust, dirt, and buildup from burners, blowers, flame sensors, and ignition components. This restores efficiency and prevents premature failure.
Airflow & Filter Care
We replace or clean the air filter and check airflow across ducts and vents. Many older Arlington rowhomes and Fairfax colonials have duct issues that restrict airflow—we identify and recommend fixes so your new season starts right.
Thermostat Calibration
We verify that your thermostat is accurate and responsive, preventing unnecessary cycling that wastes energy and strains equipment.
Safety Testing
We test for carbon monoxide leaks, check gas lines for secure connections, and ensure all safety switches are operating properly. In homes with propane systems (common in Loudoun), we also check tank connections and regulators.
Performance Testing
Finally, we measure temperature rise, airflow, and efficiency output so you know your system is performing exactly as it should.
A tune-up checklist and local know-how are only valuable if the work is done by professionals who understand Northern Virginia’s homes and climate. That’s why so many families turn to HVAC & Plumbing Unlimited. From historic Arlington rowhomes to new builds in Loudoun, we know what it takes to keep heating systems running safely and efficiently here.
Local Factors That Make Maintenance Essential
Northern Virginia isn’t just another market—it has unique conditions that put added strain on heating systems:
Heavy winter usage – January and February bring near-constant runtime. Without a tune-up, that workload accelerates wear and tear.
Freeze–thaw cycles – Rapid shifts from mild to frigid temperatures stress both furnaces and heat pumps.
Mixed housing stock – Older homes in Alexandria and Arlington often have aging ductwork, while larger Fairfax homes demand precise airflow balance to avoid hot and cold spots.
Fuel diversity – From Dominion Energy gas furnaces to propane systems in rural Loudoun, each heating setup requires different care.
Because we live and work here too, our maintenance approach is designed around these local realities—not a generic checklist.

What You Can Do Between Tune-Ups
Professional maintenance once a year is essential, but there are simple things you can do in between visits to keep your system in top shape:
Check filters monthly – Replace them every 90 days (or sooner if dirty) to keep airflow unrestricted.
Keep vents clear – Move furniture, rugs, and drapes away from registers so your system isn’t straining against blockages.
Vacuum around your furnace – Prevent dust buildup around sensitive components.
Test your thermostat – Before cold weather sets in, make sure your thermostat responds properly and your system cycles on.
