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:

Lower utility bills
Reduced repair costs
Longer system lifespan
More consistent, comfortable heat
Improved indoor air quality
Better safety, especially for gas furnaces

If you want your system to last and avoid stressful breakdowns, yearly maintenance is the most important step you can take.

We Service Furnaces, Heat Pumps & Hybrid Systems

Our technicians maintain all types of heating systems, including:

Gas and electric furnaces
Heat pumps
Dual-fuel/hybrid systems
Packaged units

We work with all major brands: Carrier, Trane, Lennox, Goodman, Rheem, Bryant, and many more.

When Maintenance Reveals a Bigger Issue

Our goal is to protect your system—not just clean it.

If we find anything concerning during your appointment—like a failing part, airflow restriction, weak ignition, refrigerant issue, or potential safety hazard—we’ll show you what’s going on and explain your options clearly.

There’s never pressure or upselling. Just honest guidance.

 Trustindex verifies that the original source of the review is Google. We just had Dave’s come out to our house today.  We thought we might have a serious issue with our heating and air system.  The two technicians cleaned and serviced the unit and let us know that our unit was fine.  We went from thinking we had an expensive problem to only having to pay a very reasonable service fee.  They were professional and wonderful to work with.  We will be using the company in the future and will recommend them to others.

 Trustindex verifies that the original source of the review is Google. I scheduled online for an AC diagnostic which was seamless. Adam came out in that time frame and gave me the run down of the issues. He was very knowledgeable and I would've went with him to fix the compressor issues.

Unfortunately, whoever this companies receptionist is sounds like she hates her life over the phone. It took them a week to get back to me with a quote. She calls me, asks if I want to get it fixed and immediately asks for my credit card info. I don't have an estimate of what's being repairs or materials they need. I tell her please send it over and I'll pay the down payment through the portal since I was driving to work. A day goes by and crickets, I get another call asking about payment. She says she sent the email but the only thing I received was a schedule confirmation. Finally it arrives and everything is still lumped into one price. It wasn't that big of a deal, but I decided to get a second quote and this other place turned an itemize quote around in an hour, came out the next day, didn't ask for a deposit, and got the job done.

If you all get that much business, the sentiment is your customers are just a number, and you can't be bothered to give the bare minimum customer experience then so be it.

 Trustindex verifies that the original source of the review is Google. I needed a new AC system due to RELAC out of business.  Todd was my first contact.  He explained my options, answered all my questions...even after he left and I continued to contact him.  He was very patient with all my concerns.  On the install day, Adam and his team arrived on time, and communicated with me during the entire process.  They explained thoroughly what they were doing and why.  They did not leave until all had been checked out, and they cleaned up thoroughly.  I will recommend them to anyone needing a new AC system.
