Annandale notes
Heating and cooling in Annandale homes
Houses from the 1950s and 60s were built before central air was common, so many Annandale homes had it added later, sometimes with ducts on the small side. When upstairs or far rooms never cool well, the ducts can matter as much as the equipment.
Gas furnaces here range from long-lived older units to high-efficiency models with plastic vent pipes and condensate drains. On the high-efficiency ones, a clogged condensate trap or drain line can shut the furnace down.
A heat pump more than about 15 years old is at the age where a big repair raises the replacement question. We'll give you the repair price and tell you what shape the system is in.
Before you call, check the filter, the thermostat and the breakers for both the indoor and outdoor units.
Older heat pumps with dirty coils or a slow refrigerant leak lose capacity on the hottest and coldest days. Cleaning the coils, and repairing the leak and recharging the system, can bring back some of that capacity.

Frequently asked questions
HVAC Repair in Annandale, VA FAQ
Can someone come fix my AC or furnace today in Annandale?
We're based in Alexandria, about 8 miles from Annandale. Same-day and next-day appointments are available when the technician route has open windows; call or book online for the earliest option. Urgent heating and cooling visits cost the same standard rate any day of the week, evenings included, right up to 10 PM. Hours run 8 AM to 10 PM Monday through Saturday and 10 AM to 10 PM on Sunday.
Many HVAC repairs are completed in a single visit once the technician has diagnosed the fault and confirmed the parts on hand. If a specific part has to be ordered, we schedule a short return visit to finish the job.
What does HVAC repair cost in Annandale?
Appliance Surgeon charges $75 for the diagnostic visit, or $115 for a double unit (such as a double wall oven, washer-dryer combo or stacked laundry), and the fee is credited toward the repair if you approve the quote. Capacitors, igniters and sensors are common, affordable repairs; compressors and refrigerant work cost more. Every visit runs the same way - diagnosis, then a firm quote you approve before repair. Urgent no-heat and no-cooling calls in Annandale, VA get priority scheduling. Typical HVAC price ranges are in our repair cost guide.
What heating and cooling problems do you fix in Annandale?
Common calls include AC not cooling, heat not working, thermostat problems, weak airflow, system short cycling and unusual HVAC noise. The exact cause is confirmed during diagnosis.
Should I repair or replace a 20-year-old heat pump?
It depends on the repair. A capacitor, contactor or fan motor is usually worth fixing even on an older system. A failed compressor or a major refrigerant leak on a 20-year-old unit often isn't. We'll give you the repair price so you can weigh it.
Do older Annandale homes need bigger ducts for central air?
Sometimes. Ducts added to an older house can be undersized or leaky, which limits how much air reaches the far rooms. We check the airflow at the registers and tell you whether the equipment or the ducts are the limit.
Should I try to fix the system myself first?
Two safe checks solve a surprising share of calls: fresh thermostat batteries and a clean filter - a clogged filter can shut a system down on its own safety limits. Beyond that, leave it to a technician. And if you ever smell gas, leave the home and call your gas company or 911 before anything else.
