Heating and AC Repair in Montgomery County

Montgomery County is one unit administratively and several practically. Who drives out to a given address is a local question, and it is worth asking before booking rather than after.

Maryland contractors. No obligation for the call.

The county decides paperwork rather than weather. Replacing a furnace or an air conditioner usually needs a mechanical permit, issued locally: one town inspects the work, the next accepts the contractor’s own sign-off, and a third wants the gas line looked at separately.

That is a question for the contractor who is quoting, and a fair one to ask early: who pulls the permit, and whether the price includes it. A replacement done without one shows up years later, when the house is sold.

The rest is decided a street at a time: the age of the house, where the equipment stands, and what the ducts were sized to carry. The town pages below are for exactly that.

The license: Held by the contractor, not by this site, and issued where the work happens — Maryland licenses at state level, at city level or not at all depending on the trade and the town. Ask for the number and the name it is held under: a trading name and the licensed entity are often not the same.
The figure: Set by the contractor and said before the work starts. This site never quotes and has no part in it. If a technician cannot say what the visit covers before beginning, that is the moment to stop.
The call: Describing what the system is doing commits you to nothing. Nothing is booked until you say so.
Coverage: By town, not by region. Montgomery County and the towns around it, and it shifts with who is taking calls at the hour you ring.
