HVAC Companies in Roanoke, VA

Search "hvac roanoke" and you'll find dozens of contractors, but no easy way to compare them without a string of phone calls. Cntrctrs flips that: submit one request, and we send it to licensed Virginia HVAC pros who quote the job directly to you. You get three to five real quotes, usually within a day, and you pick the contractor — no cold calls, no sales visits just to get a number.

Roanoke's housing stock matters here. With a median year built of 1959 and 52% of homes built before 1960, a lot of ductwork and equipment in this city was sized for furnaces and window units that no longer exist. That history changes what a fair quote looks like, and it's exactly what local pros account for when they bid your job.

Roanoke sees 3,828 heating degree days and 1,394 cooling degree days a year, so furnace work carries more weight in a typical quote than air conditioning. Local systems are sized to a 14°F heating design temperature and a 96°F cooling design temperature, which is why undersized equipment shows up fast in a Roanoke winter. Here's what homeowners typically pay for the most common HVAC jobs in the area.

Jobs land at the low end when the unit is easy to access, the ductwork is intact, and the technician can diagnose the issue on the first visit. Prices climb toward the top of the range for attic or crawlspace installs, systems requiring duct modifications, or homes with pre-1960 wiring that needs an electrician involved before HVAC work can proceed.

A dead furnace during one of Roanoke's 68 days a year that drop to freezing is a genuine emergency — pipes and health are at risk within hours, not days. AC repair in Roanoke is usually less urgent by comparison; cooling failures are uncomfortable but rarely dangerous, except during the 33 days a year the city reaches 90°F, when elderly residents or medical equipment may be at risk. Most other issues, from a noisy blower to a slow-to-cool system, can wait for a standard appointment scheduled within a day or two.

Emergency dispatch typically adds $75 - $150 to the standard service call, and nights or weekends can push the total call-out fee to $150 - $250 before repairs even start. Contractors reserve those rates for situations that can't wait until normal business hours.

• No heat when temperatures are near or below freezing
• Gas smell, carbon monoxide alarm, or visible electrical arcing at the unit
• No cooling during a 90°F+ stretch for infants, elderly residents, or medical equipment
• Water leaking from indoor equipment onto flooring or ceilings

Everything else — annual tune-ups, minor noises, thermostat questions — is worth scheduling as routine work instead of paying premium rates.

Virginia requires HVAC contractors to hold a license through the Department of Professional and Occupational Regulation, typically a Class A, B, or C contractor license depending on project size. Individual technicians who perform installation or repair work generally need a tradesman license in HVAC, and the business itself must carry general liability insurance. Roanoke's building department also requires a permit for furnace or AC replacement, new ductwork, or any change to the fuel source or electrical circuit feeding the system.

Skipping the permit step is a common shortcut among unlicensed operators, and it can leave a homeowner without recourse if the installation fails inspection later. There is no need to call DPOR, because the whole record is online and Virginia's structure rewards a minute spent on it. Contractor licences come in three classes set by project value: Class C for the smallest jobs, Class B in the middle, and Class A unlimited. On top of the class, the licence has to carry the HVAC specialty designation for this work, and the individual performing it should hold a tradesman licence at journeyman or master level. DPOR's lookup returns the class, the specialties and the status from the number, so ask for it and check that the class covers a job your size.

• Active Virginia DPOR contractor license (Class A, B, or C)
• Individual tradesman license for the technician performing the work
• General liability insurance and workers' compensation coverage
• A permit pulled for equipment replacement or new installation, not just the repair itself

How much does hvac installation cost in Roanoke?

A full furnace replacement typically runs $4,000 - $8,000, and a full AC replacement runs $4,500 - $8,500, depending on unit size and ductwork condition. Homes with older ductwork or electrical panels from the pre-1960 building era often land toward the higher end. Getting 3-5 quotes side by side is the fastest way to see where your specific job falls.

How fast can I get AC repair in Roanoke?

Most licensed contractors can schedule a standard AC repair within one to two days, and same-day service is common once the problem is diagnosed. During Roanoke's 33 days a year that hit 90°F, contractors tend to prioritize no-cooling calls over routine maintenance. Submitting one request through cntrctrs gets multiple contractors looking at your job at once instead of waiting on a single callback.

Why does my furnace struggle to keep up in Roanoke winters?

Roanoke logs 3,828 heating degree days a year, and equipment is sized to a 14°F heating design temperature, so an undersized or aging furnace shows its limits fast. Homes built before 1960 — 52% of the city's housing stock — often have ductwork designed for smaller, older systems that don't match a modern furnace's output. A licensed technician can measure your ductwork and load before recommending a replacement size.

Do I need a permit for a new furnace or AC unit in Roanoke?

Yes, Roanoke's building department requires a permit for full system replacement, new ductwork, or changes to the electrical circuit or fuel line feeding the unit. Simple component repairs, like replacing a capacitor or blower motor, usually don't need one. Your contractor should pull the permit as part of the job, not leave it to you.

What if my house still has original 1950s ductwork?

With a median year built of 1959, a large share of Roanoke homes still run ductwork sized for equipment that's long gone. Leaky or undersized ducts can waste a meaningful share of a system's output before air ever reaches a room. A tune-up or duct cleaning visit is the cheapest way to find out whether ducts need resizing before a new furnace or AC goes in.

How do I compare hvac contractors in Roanoke without making calls?

Submit one description of your job through cntrctrs and licensed Virginia HVAC contractors send their quotes directly to you. You'll typically have 3-5 quotes to compare within about 24 hours, with no cold calls or unsolicited sales visits.
