Phone is fastest.

  • Hours — Mon–Fri 7:00am–6:00pm · Saturday 8:00am–2:00pm · 24/7 emergency service
  • Emergency — 24/7 emergency heat and no-cool response. No-heat and no-cool calls are triaged on the phone first; roughly one call in six is solved before we dispatch, and we would rather tell you that than bill you for it.
  • Service radius — approximately 30 miles from Olney, covering Silver Spring, Olney, Potomac, Bethesda, Germantown, Takoma Park and the surrounding Montgomery County communities.
  • Diagnostic fee — quoted before we dispatch, and applied toward the repair or toward a replacement booked within 30 days.

Before you call, if you can

Have the thermostat reading, whether the outdoor unit is running, when the filter was last changed, and the model number from the equipment data plate. Those four things routinely cut the visit — and the bill — considerably.

Six core service areas across Montgomery County, all inside a thirty-mile radius of our Olney base. Each one has its own housing stock, its own permitting quirks and, in places like Glen Hills and outer Olney, its own utility situation — which is why we write about them separately rather than treating the county as one market.
