Service line 01
The part of the house nobody looks at until it stops. HEART AND DAGGER SOUTHERN LTD maintains boilers, water heaters, air handlers, thermostats and panels with in-house engineers who write down every reading, photograph what they find and hand you a scope you can actually read.
The problem
It usually starts as something almost nobody notices. The furnace takes a few extra minutes to catch up. The shower runs cold for the last thirty seconds. A panel in the basement has a breaker that trips when the dryer runs. Each one is survivable on its own, and together they add up to a house that feels subtly wrong all winter.
The trouble is that most repair companies are called after the fact. By then the cheap fix is gone and the expensive one remains: a failed pump that has been dragging water through a failed bearing, a scaled tank that quietly raises your energy bill every month, a condensate line that emptied into the wall cavity instead of the drain.
HEART AND DAGGER SOUTHERN LTD takes the opposite approach. Our engineers measure first. Pressure, temperature, amperage, flue draft, filter condition, vent sizing — written down on the same sheet you receive. Then we tell you plainly which of those numbers is fine, which one is drifting, and what it will cost to fix it before it becomes an emergency.

How an engineering visit runs
The engineer photographs the equipment, notes the model and serial numbers, and asks how the system behaves on a normal day. Your description of the noise is often half the diagnosis.
Static pressure, manifold pressure, flue draft, amp draw, temperature rise. Numbers on paper, not impressions in the head. This is where the drifting components reveal themselves.
HEART AND DAGGER SOUTHERN LTD explains what each reading means for your comfort and your bill, and marks each item as urgent, worthwhile or fine. No jargon, no pressure to replace something that still has years left.
Work is listed line by line with a fixed price per line and a realistic timeline. You approve the document, or ask us to trim it. Both are fine.
You receive the readings, the photographs, the parts used and a two-year written workmanship commitment on the completed work. The report stays in your documents folder, not ours.
The panel
Most panels we open in this country have at least one of three problems: circuits that were never labelled, so nobody knows what the breaker labelled "spare" actually feeds; a few connections that have loosened with thermal cycling and now run warm; and aluminium wiring on older circuits that deserves a closer look than a casual tightening.
HEART AND DAGGER SOUTHERN LTD labels every circuit in plain language, tests each one under load and reports the results. It is unglamorous work, and it is the single most useful thing you can do for an older house.
We will also tell you when a panel needs replacing rather than patching. That happens, and you should hear it from someone who is not selling you a panel.
Questions
Both. HEART AND DAGGER SOUTHERN LTD services equipment, replaces failed components and coordinates full replacements where a new unit is genuinely the sensible route. If a repair would cost more than half of a replacement, we tell you that on the spot.
We stabilise first so the house is safe and warm, then we write up the permanent option and agree the price with you before proceeding. You will not find a surprise line on the final invoice.
Yes. Our engineers work with boilers, tankless heaters, heat pumps and air handlers of many makes and ages, and with panels installed before current standards. If a part is genuinely unobtainable, we tell you before we start.
Yes, every night of the year. HEART AND DAGGER SOUTHERN LTD answers the dispatch line around the clock and puts a technician on the road within 60 minutes of a confirmed emergency.
Ready when the weather turns
Send the details of your home and equipment and HEART AND DAGGER SOUTHERN LTD will return a scope and a price. No charge for the diagnostic visit when you book the work afterwards.
