Why Local Homeowners Call Our Team

Many people tell us their biggest worry is being pushed into buying a new system when a repair might be enough. We built our business around honest, unbiased recommendations, so you can feel comfortable asking questions and comparing options. We explain what we find, what it means, and what we would do if it were our own home.

Since 2004, we have helped families and property owners in Sterling make informed decisions about their heating systems. As a minority and family-owned company, we answer to our community, not to a distant corporate office. That is one reason our work has been recognized by the Sterling Business Hall of Fame and why many customers refer friends and neighbors to us.

We know that cost matters. That is why we offer free estimates and price comparisons, so you can see how our recommendations stack up before you decide. We discuss repair options, potential replacement choices, and what each path could mean for safety, comfort, and long-term operating costs.

When repairs or replacements become larger projects, we provide flexible financing options to help you plan. Our 10-year warranty on services and products gives you long-term protection, which reflects our “done once, done right” mindset. We work carefully, because we expect our work to last.

Heating problems do not always wait for a convenient time. We offer same-day service appointments when our schedule allows, especially during colder stretches in Northern Virginia. Our team is well-versed in modern HVAC technology, so we can handle newer high-efficiency furnaces along with older systems that have been in Sterling homes for years.

What To Do If Your Furnace Fails

A furnace problem can feel urgent, especially when temperatures drop. Taking a few simple steps before you call can help protect your home and make your visit more efficient. It can also give you peace of mind while you wait for help.

If your heater suddenly stops, first take a breath and look for anything that seems unsafe, such as a strong gas smell. If you notice a burning odor, smoke, or anything that makes you uneasy, turn the system off at the thermostat and, if needed, at the switch or breaker. Your safety is always the top priority.

If there are no obvious safety issues, you can check a few basics. Make sure the thermostat is set to heat, confirm the temperature setting, and see whether the fan is set to auto or on. Look at your electrical panel to see if a breaker has tripped, and check that any furnace switch nearby is set to on. If you know where your air filter is, see whether it is extremely dirty, since that can affect operation.

Unusual sounds, repeated on and off cycling, or cold air from vents often mean it is time to call a professional. That is especially true in this area, where a night without heat can quickly make the house uncomfortable. When you contact us, telling us what you noticed, how long it has been happening, and any error codes on the furnace can help us prepare.

When you are ready to schedule, our office will work with you to find a time that fits your day. Our technicians arrive with the tools and parts needed for most common issues, and they will talk through what they see before any work begins. You remain in control of the decision, and we stay focused on safe, effective solutions.

Our Furnace Service Process

Knowing what to expect from a service visit can make the situation feel much more manageable. We follow a clear, consistent process, so you are never left guessing what comes next. From the first call to the final system check, communication is a priority for our team.

When you contact Zagros Heating & Air Conditioning, we gather basic information about your home or business, your furnace, and the issues you are seeing. We then schedule a visit at a time that works for you and give you a reasonable arrival window. Our goal is to respect your time while still allowing our technicians enough time to perform a thorough evaluation.

On site, our technician will listen carefully to your description of the problem and any previous work that has been done. They inspect key components, such as the burner assembly, blower, ignition system, and safety controls, and may also look at related parts of your HVAC system. If ductwork or airflow appears to be part of the issue, we take that into account and explain what we notice.

Once we understand what is going on, we walk you through our findings in plain language. We explain the likely cause, what could happen if the issue is not addressed, and any options you might have. Before any repair begins, we provide a clear estimate and encourage you to ask questions or take time to think about your decision.

When you approve the work, we complete the repair or replacement with attention to detail that matches our “done once, done right” approach. After the work is finished, we test the system to confirm proper operation, check for safe combustion where applicable, and make any necessary adjustments. We then review what was done, answer your questions, and discuss any maintenance steps that could help your system run more efficiently.

We also remind you about warranty coverage on the work performed and the products installed. Our 10-year warranty is designed to provide long-term reassurance and it reflects the confidence we have in our craftsmanship and the equipment we recommend. We want you to feel that you have a trusted heating partner here in Sterling, not just a company you call once.

Common Furnace Problems We Handle

Over time, even a well-built heating system can develop issues. Some problems show up slowly, like a gradual rise in utility bills or one room that never seems warm enough. Others arrive all at once, such as a furnace that will not turn on at all on a cold morning in Sterling.

Common symptoms include uneven temperatures, loud or unusual noises, frequent cycling, or air that feels cooler than it should. In many cases, these issues can point to things like dirty burners, worn blower components, ignition troubles, or airflow restrictions. Sometimes the furnace itself is working, but older or undersized ductwork makes it hard to keep certain rooms comfortable.

Our job is to sort out what is really happening, then explain it clearly. We look at the age and condition of your furnace, any past repairs, and any safety concerns before we recommend a path forward. If a repair is sensible, we say so. If replacement seems like the smarter long-term choice, we explain why and what your options are.

We work on a range of heating systems, from older gas furnaces in long-established Sterling neighborhoods to newer high-efficiency units in recent developments. Our technicians stay current with advances in HVAC technology, so we can service modern control boards and integrated systems along with more traditional setups. We also consider how your furnace interacts with your ductwork and indoor air quality when we develop recommendations.

Some of the furnace problems we commonly address include:

• No heat or insufficient heat through some or all rooms
• Furnace turning on and off more often than usual
• Unusual banging, squealing, or rattling noises during operation
• Burning or musty odors that come on when the system runs
• Higher gas or electric bills without a clear explanation

Heating Comfort For Sterling Properties

Winters in Northern Virginia can bring stretches of cold weather that make a reliable heating system more than a convenience. It protects your comfort, your building, and in some cases your business operations.

Because we have worked in Sterling since 2004, we understand the mix of older homes, newer communities, and light commercial spaces in the area. We see patterns in furnace wear, duct layouts, and insulation levels, and we use that knowledge when we evaluate your system. Our goal is to recommend solutions that match how you really use your space.
