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.

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.

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.

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.

Check the simple things first: make sure the thermostat is set to HEAT and the fan to AUTO, and replace the air filter if it’s dirty, since a clogged filter can trip the high-limit switch and shut off the burners. Other common culprits include a failed igniter, a dirty flame sensor, or pilot/ignition problems. Anything involving the gas valve, flame sensor, or ignition should be handled by a professional for safety.

A common guideline is the $5,000 rule: multiply your system’s age by the repair cost, and if the result exceeds $5,000, replacement usually makes more sense. As a rule of thumb, replace if your AC is over 10 years old or your furnace is over 15 years old, if repairs approach 50% of replacement cost, or if there’s a safety issue like a cracked heat exchanger. Newer systems with occasional minor repairs are almost always worth keeping.

A new HVAC system in the Washington, DC area typically costs between about $5,000 and $12,500 installed, with full furnace-and-AC combinations often landing in the $11,000 to $14,000 range. Final pricing depends on system size, efficiency rating, fuel type, and any ductwork or electrical upgrades. DC homeowners switching from gas to an electric heat pump may offset a large portion of that cost through DCSEU rebates.
