When your AC quits on the hottest day of summer or your heat pump struggles through a cold snap, you want someone who'll show up quickly and do the job right. That's what we've been doing for Fairfax homeowners and businesses for more than two decades.
We're not a big national chain dispatching technicians from hours away. We're your neighbors—a local team that understands the quirks of DMV weather and the specific challenges homes and buildings in Fairfax face. When you call Ducco, you get someone who knows the area and cares about doing right by the community.

Why Fairfax Residents Call Us
We've built our reputation one job at a time—showing up when we say we will, explaining things in plain English, and standing behind our work. No high-pressure sales tactics, no recommending replacements when a repair will do. Just honest service from people who take pride in their craft.
Many of our customers in Fairfax have been with us for years. They call us because they know what to expect: fair pricing, quality work, and a team that treats their home like we'd treat our own.
The Ducco Difference
Local & Responsive
We're based right here in the DMV. When you need us, we can get to Fairfax quickly.
Straight Talk
We explain what's wrong and what it'll cost before we start any work. No surprises.
Respect for Your Home
We wear shoe covers, lay down drop cloths, and clean up when we're done.
Work We Stand Behind
If something's not right, we'll make it right. That's how we've stayed in business for 20+ years.
A Note About Emergency Service
HVAC emergencies don't check your calendar first. If your system fails on a weekend or after hours, give us a call. We offer emergency service for residential customers in Fairfax because we know that a house without AC in August—or heat in January—isn't just uncomfortable. It can be a real problem for your family.
We can't always promise same-day service (it depends on what else is going on), but we'll do our best to get to you as quickly as possible.
Common Questions from Fairfax Customers
For scheduled appointments, we typically have availability within a few days. For urgent issues, we do our best to get there same-day or next-day depending on our current schedule. Give us a call and we'll let you know what's realistic.
Yes! We work with homeowners, landlords, property managers, and business owners throughout Fairfax. Whether it's a single-family home, a townhouse, an office building, or a restaurant, we can help.
It depends on the age of your system, the cost of the repair, how often you've been having problems, and your comfort goals. We'll give you an honest assessment—sometimes a repair makes sense, sometimes replacement is the smarter investment. We'll help you think through it.
We service all major HVAC brands. Whether your system is from Carrier, Lennox, Trane, Rheem, Goodman, or another manufacturer, our technicians can diagnose and repair it.
We understand that a new HVAC system is a significant investment. Ask us about available options when we provide your estimate.
If your AC isn't cooling, check that your thermostat is set correctly and your filter isn't clogged—sometimes it's something simple. If it's a safety concern (like a gas smell or burning odor), turn off the system and call us right away.
