Keep Your Heating System Running Smoothly All Winter
Annual maintenance is the easiest, most effective way to prevent breakdowns, lower energy costs, and keep your home safe and warm. With nearly five decades of experience, Dave’s Heating & Air delivers detailed, reliable service that keeps your system performing its best—season after season.
Keep Your Home Warm, Safe, and Efficient All Winter
When temperatures drop in Reston and across Northern Virginia, your heating system becomes one of the hardest-working parts of your home. A yearly check isn’t just routine—it’s the best way to avoid surprise failures, improve efficiency, and keep your home comfortable through even the coldest days.
At Dave’s Heating & Air, our maintenance service is designed to protect your system, reduce the risk of mid-season breakdowns, and help your equipment operate safely and efficiently.
Why Regular Heating Maintenance Matters
Your heating system contains burners, blowers, sensors, safety switches, electrical components, and controls that all have to work together. When even one part slips out of spec, you may notice:
Higher energy bills
Longer run times
Uneven temperatures
Strange noises or odors
Frequent on/off cycling
Routine maintenance catches these issues early, long before they turn into a “no heat” emergency. A well-maintained system lasts longer, runs safer, and costs less to operate.
What’s Included in a Heating Maintenance Appointment
We don’t believe in quick, five-minute “clean and checks.”
Our maintenance visits are detailed, thorough, and built to ensure your system is ready for the demands of winter.
Your service may include:
Inspecting burners, ignition systems, and heat exchangers
Testing blower motors and airflow
Checking safety switches and control boards
Verifying gas pressure and combustion (for furnaces)
Confirming proper operation of heat pumps and auxiliary heat
Tightening electrical connections
Inspecting flue and ventilation components
Calibrating the thermostat
Cleaning or replacing filters
Identifying worn or failing parts before they cause trouble
Before we leave, we review our findings so you know exactly what to expect from your system throughout the season.
The Benefits of Annual Heating Maintenance
A single annual visit pays for itself through better performance and fewer repairs.
Homeowners typically see:
