Rockville notes
Heating and cooling in Rockville
Many of Rockville's townhouse communities run on heat pumps, while older single-family houses like those in Twinbrook more often have a gas furnace with central air. The two struggle at different moments: heat pumps in the first hot spell and the first hard freeze, furnaces when they're switched on for the first time in the fall.
A heat pump that can't keep up in very cold weather leans on its backup heat, which is expected. One that leans on backup heat in mild weather has a problem worth fixing before the electric bill shows it.
A furnace that runs a few seconds and shuts off usually has a dirty flame sensor. One that won't start at all may have a failed igniter, an inducer motor problem or, on high-efficiency models, a blocked condensate drain.
Before the season changes, replace the filter and run the system for a few minutes. It's easier to find a problem in October than in January.

Furnace and heat pump repair in Rockville
We repair gas furnaces, heat pumps and air handlers in Rockville, MD. What the common heating calls usually come down to:
- Furnace tries to light, then shuts off. Usually a dirty flame sensor, a worn igniter or a pressure switch fault. Note how many times it retries before it locks out.
- Heat pump runs all day but the house stays cool. Often low refrigerant, a stuck reversing valve or a failed outdoor fan or capacitor. Steam off the outdoor unit during a defrost cycle is normal.
- No heat at all. Check the thermostat mode and batteries, the furnace power switch, the breaker and the filter. If you smell gas or a carbon monoxide alarm sounds, leave the home and call your gas utility or 911 from outside.

Frequently asked questions
HVAC Repair in Rockville, MD FAQ
Can someone come fix my AC or furnace today in Rockville?
We're based in Alexandria, about 20 miles from Rockville. 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 Rockville?
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 Rockville, MD get priority scheduling. Typical HVAC price ranges are in our repair cost guide.
What heating and cooling problems do you fix in Rockville?
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 runs constantly in winter. Is that normal?
In very cold weather, long run times are normal for a heat pump. If it runs constantly in mild weather, or the house won't reach the setting, check the filter and the outdoor unit for ice, then book a visit.
Should I test my furnace before winter?
It's a good idea. Replace the filter, set the thermostat a few degrees above room temperature and let it run. A burning-dust smell for a few minutes is normal on the first run; repeated shutoffs, error lights or no heat are worth booking early.
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.
