20 Years in Washington, DC
Nobody wants to spend another summer negotiating with a stubborn thermostat, another winter hoping the furnace holds on one more week, or another allergy season sneezing through their own living room.

Fortiz HVAC Inc has served Washington, DC for 20 years, handling air conditioning, heating, ductwork, and indoor air quality under one standard: find the cause, fix it completely, and stand behind the work.

What Washington, DC Calls Us For
Long, humid summers put serious strain on air conditioning systems, and our AC installers keep them running with repair, installation, and maintenance built around how your home uses its system. We service every major brand and recommend only what your system needs, nothing more.
A furnace failing on a cold night doesn’t wait for business hours, and neither do we. Our technicians diagnose the problem accurately on the first visit and carry parts for most major brands, so most heating repairs finish in a single trip, not three.
A lot of older housing stock runs ductwork that was never designed for the home it’s sitting in. Our ductwork technicians handle duct installation, duct repair, and duct cleaning, including full drywall access when a proper fix calls for it.
Clean air makes all the difference, and we’re here to help you get it. From air filter replacements to UV light installations, we do it all to restore fresh, clean air. Whether it’s comfort or tackling seasonal sniffles, our indoor air quality services are built for a healthier, cleaner home.

DC summers don’t play nice. Heat and humidity climb for weeks, and air conditioners end up working far harder than most homeowners expect. Systems that seemed fine in spring can start struggling once the heat settles in, especially in homes where airflow or ductwork issues were never fully addressed.
Washington, DC winters aren’t always brutal, but they can change quickly. A single sharp cold snap is often enough to expose a furnace that’s been struggling quietly in the background, especially in older systems where warning signs go unnoticed until temperatures drop and demand suddenly rises.
Many DC rowhomes were built long before central air became standard, and ductwork was often added wherever space allowed. That approach can create airflow issues, uneven temperatures, and systems that work harder than they should just to keep every room comfortable.
DC pollen season hits hard every spring, and the effects don’t stay outside. Pollen makes its way indoors, settles into ductwork, and continues circulating through your home long after allergy season peaks outdoors. Over time, it can impact indoor air quality and overall comfort.
Rowhomes and multistory DC properties often rely on one thermostat controlling several levels, and that setup can make balanced comfort difficult. The top floor may feel warmer in summer while lower levels stay cooler, creating frustrating temperature differences caused by the home’s layout rather than a single system issue.
Washington, DC has its own building codes and permitting requirements separate from Maryland and Virginia. Working with a local HVAC contractor means having a team familiar with these standards, local housing challenges, and the requirements needed to complete projects properly from start to finish.
Day or Night, Heating or Cooling Problem, We’re Here for You
A dead AC in a DC heatwave or a furnace that quits on a January night doesn’t wait for convenient timing, and neither does our team. Fortiz HVAC Inc offers fast, same-day response for DC homeowners facing a genuine HVAC emergency, with honest communication about timing from the first call.
If your comfort or safety is on the line – no cooling in extreme heat, no heat in a cold snap, we prioritize getting a technician to your DC home the same day the call comes in.
Whether it’s a quick question or a system down completely, our family-run team picks up, explains what’s happening, and gets your visit scheduled without the runaround. Call now for immediate help.
Eight Reasons
Fortiz HVAC Inc is fully licensed, with technicians who are NATE-certified and EPA 608 certified. That means every repair, installation, and duct project meets code, not a shortcut version of the job.
That kind of experience means our ductwork specialists have already run into whatever’s happening behind your walls. It shows up as fewer callbacks and fixes that genuinely hold.
A sudden heatwave or a winter cold snap doesn’t leave room to wait a week for service. Our technicians prioritize same-day scheduling for anyone facing a genuine comfort or safety issue.
Properly sized ductwork and correctly installed systems mean your equipment isn’t fighting a bad layout to hit the temperature you set. Efficiency gets designed in from day one.
Regular maintenance catches small issues, like a failing capacitor or a drifting duct seal, before the next heatwave or cold snap turns them into an emergency repair bill.
Every customer gets a detailed, itemized estimate before work begins, with financing available through Wisetack for larger installations and repairs that don’t fit neatly into a single paycheck.
Most of our business comes from homeowners who already had work done and told a neighbor, not a coupon or a discount code. That’s the kind of reputation you can’t buy.
When our ductwork specialists design and install a system, the same team is the one you call if anything needs a second look, not a subcontractor who’s already moved on.
