Local considerations
Freeze-thaw winters affect both heat pumps and gas furnaces, often in the same neighbourhood. That is also why a Rockville autumn tune-up pays for itself more reliably than a spring one on the heating side.
Freeze-thaw winters affect both heat pumps and gas furnaces, often in the same neighbourhood. That means Rockville homeowners who defer maintenance past the first autumn cold snap are statistically more likely to face an emergency call than those who booked service before the season started.

What is your thermostat reading?
Drag the dial to the temperature your thermostat shows now. The readout names the likely cause band, how urgent it is, and which page to read next.

- Read next
- AC not cooling
What to do while you wait
- Set the thermostat to off rather than leaving it calling for heat against a locked-out system.
- If you smell gas, leave the building first and call the gas utility or 911 from outside.
- Replace a loaded filter. Restricted airflow trips high-limit switches on furnaces.
- Close off unused rooms and keep anyone vulnerable in the warmest part of the house.

Problems we route in Rockville

Rockville HVAC questions
Do I have to be home?
Yes. The technician needs access to the thermostat and the equipment itself, and someone has to approve the quoted price before work begins. For combustion appliances they may also want to check alarms.
What does heating repair cost in Rockville?
We do not quote prices. The provider who attends confirms the price on site before work begins. Boiler and heat pump work generally takes longer to diagnose than a straightforward furnace fault.
What should I do before the provider arrives?
Set the thermostat to off rather than leaving it calling for heat against a locked-out system, replace a loaded filter, and close off unused rooms. Keep anyone vulnerable in the warmest part of the house.
What if my furnace is still under warranty?
Parts warranties of five to ten years are common, labor warranties are not. Have the model and serial number ready when you call so the provider can check coverage before fitting anything.
My furnace locks out after three tries. What is that?
Three failed ignition attempts followed by a lockout usually means the flame sensor is dirty, the igniter is weak or gas pressure is wrong. After a long idle summer, cleaning resolves it more often than replacing parts does.
