Four routes, not one
What you're actually choosing between
Far cheaper than standby, and it removes the extension cords and the backfeed risk entirely.
We'll walk through which fits your outage pattern, your budget, and whether being away during an outage matters to you.
Where quotes diverge most
Whole house, or what matters?
Typically heating, refrigeration, a few lighting circuits, well or sump pump, garage door, and outlets for phones and medical equipment. Usually enough to make an outage a nuisance rather than an emergency, and it allows a considerably smaller and cheaper unit.
Everything, including the large loads — central air conditioning, electric range, electric water heating, EV charging. Requires a much larger generator and, on propane, a much larger tank.
Many modern standby systems include load management, which sheds or staggers large loads automatically so a smaller generator can serve a whole panel — running the air conditioning or the range, rather than needing capacity for both simultaneously. That frequently allows a meaningfully smaller unit for the same practical result.
A proper sizing exercise looks at your actual connected loads, your motor starting loads (which draw far more than running loads for a moment), and what you genuinely want available. We'll show you the numbers rather than quoting a size from a rule of thumb.
The critical equipment
Transfer switches, interlocks, and why backfeeding kills
A generator must never be able to feed your house and the utility grid at the same time. That separation is the entire purpose of this equipment.
Backfeeding has none of this Running a cord from a generator into a wall outlet energises your household wiring and, through the service, the utility lines outside — which is how line workers are killed during restoration. It's illegal in most jurisdictions and it will not be part of anything we install.
Fuel
What each one costs you in practice
Natural gas
No refuelling, no storage, no run-time limit as long as the gas supply holds. Requires an adequately sized gas line — a generator is a large appliance and existing piping is often undersized for it, which is a common add-on cost. Units generally produce slightly less output on natural gas than on propane.
Propane
Stores well, burns cleanly, and works where there's no gas service. The constraint is tank size: run time is finite, and a multi-day outage means planning refills — during the same event everyone else is planning refills. Size the tank for the outage you're actually preparing for.
Diesel
Common in larger and commercial applications. Fuel storage, periodic turnover, and cold-weather handling all need managing.
Petrol (portables)
Convenient and widely available, but stores poorly without stabiliser, requires you to be present to refuel, and means keeping fuel on the property safely.
Fuel choice usually follows what's already at the property. Where there's a choice, it's mostly a trade between refuelling hassle and installation cost.
Position
Placement, clearances, and noise
- Clearances matter and they're not negotiable. Standby generators have manufacturer-specified minimum distances from the building, and code and local rules add requirements around windows, doors, and air intakes — because exhaust must not find its way indoors.
- Property line setbacks apply in many municipalities, and some have noise ordinances that affect placement or permitted exercise times.
- Noise. Standby units are considerably quieter than portables but not silent, and they run a weekly or monthly exercise cycle. Placement relative to your own bedrooms and your neighbours' is worth thinking about before the pad is poured.
- HOA and strata rules frequently govern generator placement, screening, and sometimes whether they're permitted at all. Check before ordering equipment.
- The pad and access. Standby units sit on a level pad — usually concrete or a manufactured composite — with room around them for service access.
We assess all of this on site, because the ideal electrical location and the ideal exhaust location aren't always the same place.
Why Apache calls us
What you get when you call Summit

Scope
What the installation involves
- Site assessment and sizing — loads, fuel, placement, and clearances.
- Permits — electrical, usually gas, and sometimes zoning or building approval depending on jurisdiction.
- Pad preparation — level base, correctly positioned.
- Electrical work — transfer switch or interlock, generator feeder, and any backup subpanel.
- Fuel connection — gas line sized for the unit's demand, or propane tank and regulator arrangement.
- Setting and connecting the unit.
- Commissioning — start-up, load testing, transfer sequence verified, and exercise schedule set.
- Inspection — coordinated with the authority having jurisdiction.
- Handover — documentation, warranty registration, and a walkthrough of operation, alerts, and maintenance.
Manual setups — inlet, interlock, and a portable — are typically completed in a day. Automatic standby installations take longer and depend on fuel and permit scheduling.
How it works

-
Options and written quote
Every route that genuinely fits — portable and interlock, manual transfer, automatic standby, battery — with prices and trade-offs.
-
Permits and scheduling
Permits pulled, fuel and utility coordination arranged, and the work scheduled.
-
Installation
Pad, electrical, fuel, and transfer equipment.
-
Commissioning and training
Tested under load, transfer verified, and you're shown how to operate and maintain it.
Maintenance
Keeping it working
A generator that fails when you need it is worse than not having one, and unused equipment is exactly what fails.
- Let it exercise. Standby units run a scheduled self-test. Don't disable it — it's what keeps the engine and battery healthy.
- The battery is the most common failure point. Standby generators start on a battery, and a dead battery means no start regardless of fuel.
- Service annually, or per the manufacturer's interval — oil, filters, and inspection.
- Keep the enclosure clear. Vegetation, snow, and stored items block airflow and exhaust.
- For portables: run them periodically, use fuel stabiliser, and don't store fuel indefinitely.
- Test after any electrical work on the property, so you find problems on a Tuesday rather than during an outage.
Commercial
Commercial and life-safety generators
We install and service backup power for restaurants, retail, offices, warehouses, healthcare and care facilities, and multi-unit residential buildings across Apache.
Commercial requirements differ fundamentally: many buildings have code-mandated emergency power obligations covering egress lighting, exit signage, fire systems, and elevators, with testing and record-keeping requirements attached. Beyond compliance, there's the commercial case — refrigeration, point-of-sale, servers, and production equipment that stop earning the moment power does.
Commercial installations typically involve three-phase supply, larger transfer equipment, and load prioritisation across multiple panels. We'll assess obligations and operational priorities together, since they're rarely the same list.

Questions
Frequently asked questions
Can I just plug my generator into an outlet?
No. Backfeeding energises utility lines and can kill line workers restoring power. It's illegal in most jurisdictions. An inlet with an interlock or transfer switch is the correct solution and isn't expensive.
Can I run my generator in the garage with the door open?
No. Portable generators produce carbon monoxide in dangerous quantities, and enclosed or partly enclosed spaces accumulate it. Run it outdoors, well away from the building, exhaust pointed away from windows, doors, and vents — and have working CO alarms inside.
Do I need a whole-house generator?
Often not. Essential circuits — heat, refrigeration, pumps, some lighting and outlets — cover most of what makes an outage difficult, and allow a much smaller unit. Load management can also let a smaller generator serve a whole panel.
What's an interlock kit?
A mechanical device on your panel that makes it physically impossible for the main breaker and generator breaker to be on at once. Where a listed kit exists for your panel, it's usually the cheapest compliant way to connect a portable.
How much does generator installation cost in Apache?
It depends most on whether you want automatic standby or a manual setup with a portable, then on size and fuel work. You'll get one written quote covering electrical, fuel, permits, and commissioning.
Natural gas or propane?
Natural gas means no refuelling and no run-time limit, but needs an adequately sized gas line. Propane works without gas service but run time is limited by tank size. Choice usually follows what's already at the property.
How long can a standby generator run?
On natural gas, as long as supply holds. On propane, until the tank empties — which is why tank sizing should reflect the outage length you're preparing for.
Does it start automatically if I'm away?
Automatic standby units do — that's their main advantage. Manual setups need someone present to start the generator and operate the switch.
Do I need a permit?
Yes — electrical, usually gas, and sometimes zoning or building approval. We handle permitting and inspection.
How noisy is it?
Standby units are much quieter than portables but not silent, and they run a regular exercise cycle. Placement relative to bedrooms and neighbours is worth planning.
What maintenance does it need?
Let it run its exercise cycle, keep the battery healthy, service annually per the manufacturer, and keep the enclosure clear of vegetation and snow. The battery is the most common reason a standby unit fails to start.
Is battery backup a real alternative?
For shorter outages and essential loads, yes — silent, no fuel, no CO, minimal maintenance. Duration is the trade-off unless it's paired with solar.
Can you connect a generator to my existing panel?
Usually. Whether via transfer switch, interlock, or a backup subpanel depends on your panel and which circuits you want covered. We'll assess and explain the options.
Size it for the outage you actually have
A generator that covers what matters, on fuel you can actually sustain, connected in a way that can't endanger anyone — that's the whole exercise. Everything else is a spec sheet.
