What we do
Heating and cooling, plumbing, electrical and appliance repair — one phone call. Every visit starts with an actual diagnosis — meters, gauges, real testing — and you get the finding, the fix, and the number before we start.
All six services
Same-day repair on every major brand, and honest replacement numbers when a system is past saving. We size with a Manual J load calculation — not by matching whatever box was there before.
Gas, electric, and heat pump. Repair tonight, replacement quoted honestly.
Refrigeration, laundry, cooking. Including the brands most shops turn down.
One room always hot? That is almost never the equipment.
Filtration, humidity, and ventilation for the people in the house.
Leaks, drains, water heaters and fixtures — the trade where waiting costs the most.
Panels, circuits, lighting and EV chargers. The symptom is rarely where the fault is.
RTUs, split systems, and make-up air for buildings that cannot close.
Guaranteed response windows
Every area we cover carries a written arrival window — as fast as 30–60 min in Frederick — so you know when somebody is actually turning up before you commit. HVAC or appliance, it is the same phone call.

How a Swift Tech call goes
Tell us the address and the symptom. We give you the arrival window for your area before you commit.
A stocked van comes to you. No showroom visit, no waiting around a vague all-day slot.
Real testing until we find the actual fault, on the HVAC system or the appliance. One flat fee, known up front.
The repair price in writing before anything starts. Approve it and the $69 comes straight back off.
Most repairs finish on the first visit, because the parts that actually fail are already on the van.
What it costs to find out
$ 69
Flat diagnostic fee. Waived if you approve the repair.
A real diagnosis takes a tech, a truck, and an hour of proper testing. We charge $69 for it and put that in writing up front — then take the full $69 back off the bill the moment you approve the work. Nothing gets padded into the repair price to cover a “free” visit.

About Swift Tech LLC
Most households keep a list of contractors — one for the heating and cooling, one for whatever is leaking, one for the electrical, and another for whatever just died in the kitchen. Swift Tech LLC does all four. The tech who diagnoses your condenser can look at the dripping vanity and the breaker that keeps tripping before he packs up.
We work out of Frederick, MD and run across Maryland and Virginia — no storefront, no showroom, no overhead baked into your invoice. Just a stocked van showing up inside the window we gave you.
The $69 diagnostic is the whole pricing conversation. We find the fault, quote the repair, and take that $69 back off the moment you say go.
Book a visit
Requests sent here are answered during business hours. If you have no heat, no cooling, or a fridge full of food, call — we will give you an arrival window on the spot.
