Reston notes
Heating and cooling in Reston homes
Heat pumps are common in Reston, especially in townhouses and condos. In winter, a heat pump that blows cool air for a few minutes is usually running a defrost cycle, which is normal. One that leans on its backup heat all the time isn't, and it shows on the electric bill.
Townhouse systems often have the outdoor unit in a small patio or side yard, close to fences and shrubs. Keep a couple of feet clear around it so it can breathe.
If you're planning to replace or move an outdoor unit, check with your cluster association or Reston Association first, since exterior changes in Reston often need approval.
Before calling, check the filter, the thermostat settings and the outdoor unit's breaker and disconnect.
Condo buildings near the Silver Line stations often have a small air handler or fan coil in each unit, with cooling supplied by an outdoor heat pump or by the building. If you're not sure which you have, the management office can tell you, and that decides who handles the repair.

Frequently asked questions
HVAC Repair in Reston, VA FAQ
Can someone come fix my AC or furnace today in Reston?
We're based in Alexandria, about 20 miles from Reston. 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 Reston?
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 Reston, VA get priority scheduling. The diagnostic visit is $75 for a single appliance 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. Typical HVAC price ranges are in our repair cost guide.
What heating and cooling problems do you fix in Reston?
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.
My heat pump blows cool air in winter. Is it broken?
Not necessarily. During defrost the system briefly runs in cooling mode to melt ice off the outdoor coil, and the air from the vents feels cool for a few minutes. If it blows cool air constantly, or the outdoor unit is encased in ice, book a visit.
Do I need approval to replace my outdoor AC unit in Reston?
Possibly. Many Reston clusters and the Reston Association have rules about exterior equipment. Repairing the existing unit usually doesn't need approval, but a replacement in a new spot might. Check your cluster's guidelines first.
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.
