What Happens After You Send It
So you are not left guessing whether it arrived anywhere.
- Londonderry scheduling is checked — service details are reviewed before follow-up.
- They ring you to schedule — usually the same business day, with no-heat and no-cool calls prioritized.
- They diagnose, then quote — the estimate arrives before the work does, and declining it is a normal outcome.
Worth Knowing Before the Visit
None of it is required. Each answer you have makes the appointment shorter and the quote sharper.
- What the air coming out is actually like. Cool-but-not-cold, warm-but-not-warm, and nothing at all are three different diagnoses.
- Whether the outdoor unit is running when the problem happens. Walk out and look — it's the single most useful observation a homeowner can make.
- Whether backup heat has been kicking in. Many thermostats show "AUX" or "EM HEAT" when it does, and that's an expensive symptom worth mentioning.
- How long a cool spell lasts. A few minutes on a repeating rhythm is usually a normal defrost cycle rather than a fault.
- Approximate age and brand of the system. The outdoor unit's data plate has both, and it shapes what parts a technician brings.
For a heat pump specifically, two extra details are worth more than everything else: whether the outdoor unit is running at all when the problem occurs, and whether your backup heat has been kicking in. Together those two answers usually separate a control problem from a refrigerant problem before anyone opens a panel.
Before You Send the Form
How soon will I hear back?
Call if it is urgent — phones are triaged as they ring, and a genuine no-heat or no-cool call moves ahead of routine scheduling in a way a form cannot. Form submissions typically get a callback the same business day, or the following morning if sent late. If a full business day passes in silence, ring the number on this page rather than sending it again; a duplicate submission does not improve your position in the queue.
Do you cover Derry, Windham and Litchfield?
Yes — they share contractors with Londonderry, so they are one service area rather than an extension of one. Choose your town in the dropdown and it routes to someone who actually covers it. If you sit outside those towns, pick "Other nearby" and tell us where you are; occasionally the honest answer is that someone closer to you is the better call, and saying so beats sending a technician on a forty-minute drive to a routine appointment.
