HVAC Repair in Alexandria, VA

From Old Town's 18th-century rowhouses to the newer West End, we keep Alexandria comfortable with same-day repairs, careful retrofits, and 24/7 emergency service.

Alexandria is one of the oldest towns in the region, and its heating and cooling needs reflect that. In Old Town, much of the housing stock dates to the 18th and 19th centuries — brick rowhouses and Federal-style townhomes built long before central air, often with thick masonry walls, low basements, and no original ductwork to speak of. Comfort in these homes usually comes down to a mix of older boiler and radiator systems, high-velocity or compact ducted setups squeezed into tight chases, and ductless mini-splits that cool a sunroom or third-floor bedroom without tearing into plaster. We work in these homes every day and understand how to add modern comfort without compromising the character that makes the neighborhood special.

That history also comes with rules. Properties inside Alexandria's historic district fall under design review, which can affect where and how exterior equipment like condensers and mini-split heads are placed. We help homeowners plan installations that respect those expectations — tucking outdoor units into side yards and courtyards, keeping line sets discreet, and choosing equipment that fits the footprint of a narrow lot. When an aging boiler quits in January or a window unit can't keep up with a Potomac-humid August, we diagnose the real issue and give you honest options, from a targeted repair to a properly sized replacement.

Newer parts of the city tell a different story. Homes and condos in the West End, along Eisenhower Avenue, and out toward I-395 typically run on conventional central air and heat pumps, where the work is more about restoring efficiency — refrigerant and capacitor faults, failing blower motors, clogged coils, and thermostats that have given up. Whatever you're working with, our licensed, insured technicians arrive on time, quote flat-rate pricing before any work begins, and stand behind every job with a satisfaction guarantee.

FAQ

Alexandria HVAC Questions

How much does HVAC repair cost in Washington, DC?

Most HVAC repairs in Washington, DC run between roughly $150 and $500, with simple fixes like a capacitor or fan motor on the lower end and major component work going higher. Expect a diagnostic or service-call fee of about $75 to $200, plus labor of roughly $75 to $150 per hour. Rates in the District tend to run higher than the national average, so always get an itemized, upfront quote before authorizing work.

Do you offer 24/7 emergency HVAC repair in DC?

Yes. We offer 24/7 emergency service for situations like a complete AC failure during a heat wave or no heat in winter, including nights, weekends, and holidays. A true emergency is generally a no-heat, no-cool, gas-smell, or active water-leak situation that can’t safely wait until normal business hours. Call us any time and we’ll dispatch a technician fast.

What counts as an HVAC emergency versus a repair that can wait?

Treat it as an emergency if you have no heat in freezing weather, no cooling during dangerous heat, a gas or burning smell, sparking, or water actively leaking near electrical components. These pose safety or health risks, especially for infants, elderly residents, or anyone with medical conditions. Issues like a slightly noisy unit, weak airflow, or a higher energy bill are real problems but can usually wait for a scheduled appointment.

How long does an HVAC repair usually take?

Most AC and furnace repairs are completed the same day, typically in one to four hours. Diagnosis usually takes 30 to 60 minutes, simple repairs like a capacitor or fan motor run one to two hours, and more complex jobs can take three to four hours. The main thing that stretches a repair into multiple days is when a special-order part is needed for an older or less common system.

Why is my AC running but not cooling my house?

The most common causes are a clogged air filter, an incorrect thermostat setting (such as the fan set to ON instead of AUTO), or a dirty outdoor condenser coil blocked by leaves and debris. You can safely check the filter, confirm the thermostat is on COOL, and gently rinse debris off the outdoor unit. If those don’t fix it, the problem is likely a refrigerant leak, frozen evaporator coil, or failing compressor, which require a licensed technician.
