Ductwork Installation and Repair in Montgomery County, VA

When your ducts are leaking, blocked, or poorly designed, your entire HVAC system pays the price. Eric's Heating & Air LLC provides professional ductwork installation and repair for homes and businesses across Christiansburg, Blacksburg, Radford, and the wider New River Valley. Whether you need a full air duct replacement, targeted duct sealing services, or a brand-new ductwork design for a Virginia property, we assess your system honestly and fix what needs fixing first.
New River Valley Duct Services
Full Ductwork Installation for Homes and Businesses
A properly installed duct system is the backbone of any heating or cooling setup. Without it, even the most efficient furnace or air conditioner will struggle to keep your space comfortable. Eric's Heating & Air designs and installs complete duct systems for new construction, additions, and full replacements across Christiansburg, Blacksburg, Shawsville, Elliston, Riner, and surrounding communities. We size and route every pathway to match your specific floor plan and equipment, so conditioned air reaches every room the way it should. Commercial clients, including offices, retail spaces, and industrial facilities, can count on the same careful approach we bring to every residential job.
Repair and Sealing Services
Duct Sealing and Targeted Repair That Stops Waste
Leaky or damaged ducts are one of the most common reasons a home feels uneven in temperature or runs up high energy bills. Gaps at joints, cracks in older ductwork, and disconnected vents all allow conditioned air to escape before it reaches living spaces. Our technicians locate the problem areas, seal them properly, and repair or replace damaged sections so your system operates the way it was designed to. Duct sealing services are available throughout Montgomery County and our extended service area, including Pilot, Floyd, and Salem. If rattling or pinging noises are coming from your vents, that is often a sign of loose panels or compromised ductwork that we can address quickly.
Honest Assessments, No Pressure
We Fix What Can Be Fixed First

At Eric's Heating & Air, we built our reputation on a fix-first approach. Before recommending a full air duct replacement, we evaluate whether targeted repairs or sealing will solve the problem. Many duct issues, including loose connections, minor tears, and improperly sealed joints, can be corrected without tearing out an entire system. Our $70 diagnostic call charge lets you get a real assessment without a large upfront commitment. We provide straightforward recommendations based on what your system actually needs, not on what generates the biggest sale. That philosophy has kept customers across the New River Valley coming back since we opened in 2015.

Ductwork Design in Virginia
Properly Designed Systems for Lasting Comfort
Good ductwork design matters as much as the quality of the equipment connected to it. Undersized ducts restrict airflow, oversized ones reduce velocity and cause temperature swings, and poorly routed pathways create hot and cold spots throughout a building. Our ductwork design process in Virginia accounts for your home or commercial space's layout, insulation levels, and the heating and cooling equipment already in place or being installed. We serve clients across Christiansburg, Blacksburg, Radford, and select project areas including Giles County and Dublin. Whether you are building new or upgrading an existing system, a well-planned duct layout makes every other investment in your HVAC system work harder for you.
Ductwork Questions Answered
Common Questions About Duct Services in the New River Valley

  • How do I know if my ductwork needs to be repaired or fully replaced?

    The answer depends on the age and condition of your existing ducts. Isolated issues like loose joints, small tears, or disconnected sections can usually be fixed without replacing the whole system. A full replacement makes more sense when ducts are severely deteriorated, extensively leaking, or so poorly designed that patching them would not produce meaningful results. Eric's Heating & Air charges a $70 diagnostic call to assess your system and give you an honest recommendation before any work begins.

  • What are common signs that my home's air ducts have a problem?

    Some of the clearest signs include rooms that stay too hot or too cold compared to the rest of the house, higher than expected energy bills, rattling or pinging noises coming from vents, and weak airflow at registers. Dust buildup near vent openings can also point to gaps or leaks in the duct system that are pulling in unconditioned air from attics, crawlspaces, or wall cavities. If you are noticing any of these symptoms, a professional inspection can identify the source of the problem.

  • Does Eric's Heating & Air handle ductwork for commercial buildings, not just homes?

    Yes. Eric's Heating & Air provides ductwork installation and repair for commercial clients including offices, retail environments, industrial facilities, and hotels. Commercial duct systems often involve more complex routing and higher airflow demands than residential setups, and each project is approached based on the specific layout and equipment involved. Service is available throughout Christiansburg, Blacksburg, Montgomery County, and surrounding communities in the New River Valley.

  • How much does a ductwork service call cost in Christiansburg?

    Eric's Heating & Air charges $70 for a diagnostic service call, which covers the technician's visit and assessment of your duct system. The cost of any repair, sealing, or installation work depends on the scope of what is needed. General service work ranges from $200 to $1,000, and full installation projects range from $6,000 to $14,000. These figures are general ranges; your specific situation will be evaluated during the diagnostic visit.

  • What areas in Virginia does Eric's Heating & Air serve for ductwork?

    The primary service area covers Christiansburg, Blacksburg, and Montgomery County. Extended service areas include Radford, Shawsville, Elliston, Riner, Pilot, Floyd, and Salem. For select installation projects, service is also available in Giles County and Dublin. If you are unsure whether your location falls within the service area, the team can confirm availability when you reach out.

  • Can duct sealing actually lower my energy bills?

    It can, yes. When conditioned air leaks out of gaps or poorly sealed joints before reaching your living spaces, your heating and cooling equipment has to run longer to compensate. Sealing those leaks means the air you are paying to heat or cool actually gets where it is supposed to go. The impact on bills depends on how significant the leakage was to begin with, but homes with older or poorly maintained duct systems often see a noticeable difference in comfort and efficiency after a thorough sealing service.

  • Does Eric's Heating & Air offer emergency duct repair service?

    Eric's Heating & Air offers 24/7 availability for urgent HVAC needs, with a targeted emergency response time of under three hours for air conditioning situations. If a duct failure is contributing to a heating or cooling emergency, the team can respond and assess the issue. The same commitment to same-day service that applies to furnace and AC repairs extends to duct-related problems that are causing immediate comfort or system issues.
