At Allred Heating Cooling Electric, our family-owned team is ready to provide the expert generator maintenance and tune-up services you need to ensure your backup power is always ready.

Warning Signs Your Generator Needs Immediate Attention

Your Generator Fails to Start During a Test

You initiate a manual test or wait for the generator to attempt its automatic weekly exercise, but nothing happens. Sometimes you might hear rapid clicking noises from the unit, but the engine simply refuses to turn over and ignite. This is a highly stressful situation because a unit that fails a low-stress test will absolutely fail during a real emergency.

This starting failure is often a clear indicator of a dead or weak battery, a deeply clogged fuel line, or an issue within the main control panel. Because backup systems often sit idle for months between local storms, battery degradation and stale fuel are incredibly common culprits. If you ignore this symptom, you are essentially leaving your home without the safety net you paid for.

Unusual Noises or Vibrations When Running

When your generator finally does run, it might make terrible grinding, clunking, or squealing noises that you have never heard before. You might also notice the entire enclosure vibrating excessively, shaking the ground around the concrete pad. A healthy engine should run with a steady, predictable hum, not a violent rattle.

These alarming sounds and physical vibrations usually point toward worn-out internal bearings, loose mechanical components, or a severely unbalanced engine. It could also indicate that the exhaust system has vibrated loose or sustained internal damage. These noises are the earliest precursors to major mechanical failure, and ignoring them almost always leads to catastrophic engine damage.

Visible Leaks or Corrosion Around the Unit

Walking past your equipment, you might spot dark puddles of oil, unburned fuel, or brightly colored coolant pooling underneath the chassis. Alternatively, you might open the access panel and find a thick layer of green or white powdery rust coating the battery terminals and wiring harnesses. Because of the persistent dampness in our local climate, this kind of environmental wear happens faster than many homeowners realize.

Leaks mean you have failing rubber seals, cracked transport hoses, or heavily compromised fuel lines that need immediate replacement. Corrosion is equally dangerous because it significantly impairs electrical conductivity, preventing the system from delivering power to your house. Leaving these leaks unchecked creates severe fire hazards, while spreading corrosion will eventually destroy the delicate circuit boards inside your unit.

Warning Lights on the Control Panel

Modern standby systems are incredibly smart and will actively tell you when they are struggling to operate. You might walk outside and see a glowing yellow or red fault code, or a maintenance required light flashing on the digital display. These lights are not mere suggestions; they are direct diagnostic alerts from the onboard computer.

Each specific code points to a distinct internal condition, ranging from dangerously low oil pressure to a failing automatic transfer switch. The system is warning you that a specific component is operating outside of its safe parameters. If you clear the code without fixing the underlying issue, a minor repair will quickly escalate into a complete system breakdown.

What is Causing Your Generator Problems

Stale Fuel and Clogged Lines

Gasoline and diesel fuels have a surprisingly short shelf life, and they rapidly degrade when sitting stagnant in a storage tank. As the fuel breaks down, it forms a thick, sticky varnish and heavy sludge that coats the inside of your fuel delivery system. This sludge easily clogs the narrow passages inside fuel lines, carburetors, and fuel injectors.

In Auburn, standby units might only be called upon a few times a year during sporadic power grid failures. This extended period of total inactivity creates the perfect environment for fuel to separate and spoil. Our maintenance process involves draining this degraded fuel, meticulously cleaning the delivery components, and installing fresh filters to restore proper flow.

Severe Battery Degradation

The 12-volt battery responsible for starting your heavy engine operates exactly like the battery inside your car. Over time, it naturally loses its ability to hold a deep charge, especially when exposed to fluctuating outdoor temperatures. Infrequent charging cycles and simple old age will eventually cause the internal lead plates to fail completely.

While our local temperatures fluctuate, the consistent cool dampness can subtly drain battery life if the internal charging alternator isn't operating at peak efficiency. We perform highly accurate load tests on your battery to determine its true health and remaining lifespan. If the battery shows signs of failing, we will swap it out before it leaves you stranded in the dark.

Moisture and Electrical Corrosion

Electricity and moisture are a terrible combination, and high humidity aggressively attacks exposed metal surfaces. This moisture causes rapid oxidation on electrical terminals, delicate circuit boards, and the heavy wiring that connects your generator to your home. Once this corrosion builds up, it acts as an insulator that blocks the flow of electricity.

The persistent rain and heavy dampness unique to the Puget Sound region make outdoor electrical equipment highly susceptible to this specific type of damage. We carefully inspect every single electrical pathway, scrubbing away early signs of oxidation. We then apply specialized protective dielectric grease to shield these vital connections from future moisture intrusion.

Worn Spark Plugs and Suffocated Filters

Spark plugs endure intense heat and pressure, and their electrodes eventually wear down, resulting in a weak spark that struggles to ignite the fuel. At the same time, the engine's air, oil, and fuel filters act as physical traps for dirt, preventing contaminants from destroying the internal cylinders. When these filters become completely saturated with debris, they choke the engine of the vital air and fluids it needs to survive.

Even a small amount of airborne dust or yard debris can prematurely clog an intake filter, forcing the engine to work twice as hard to pull in oxygen. During a thorough tune-up, we pull and replace these worn spark plugs to restore instant ignition capabilities. We also swap out all critical filters so your engine can breathe easily and run cleanly.

Twin brothers Matt and Dan founded this company in 2011 with a strict focus on honest pricing and superior service, ensuring you never have to deal with aggressive upselling. Our skilled technicians arrive fully prepared to perform a comprehensive inspection and tune-up on your standby system.

We believe in flat-rate repairs, meaning you will always know exactly what a service costs before we ever pick up a wrench. Every tune-up we perform is designed to catch small issues before they snowball into massive emergencies. Here is exactly what happens when our professionals arrive at your property.

Comprehensive Visual and Fluid Inspection

We start by carefully walking around the exterior enclosure, checking for physical damage, compromised weather stripping, and signs of pest intrusion. We inspect the heavy fuel lines, exhaust pipes, and concrete mounting pad to ensure the entire installation remains structurally sound. Once the exterior is cleared, we move inside the cabinet to check the vital fluids.

Our technicians will measure the engine oil and coolant levels, looking for signs of contamination or thermal breakdown. We completely drain the old, degraded engine oil and replace it with premium synthetic lubricants designed for extreme conditions. We also install a brand-new oil filter to trap microscopic metal shavings and keep the internal engine components protected.

Electrical System and Battery Assessment

Because your generator is fundamentally an electrical device, we spend a significant amount of time testing its voltage output and internal wiring. We inspect the heavy-duty alternator, checking the brushes and stators for excessive wear or heat damage. We also clean and tighten every major electrical terminal to prevent the corrosion problems so common for homeowners in Auburn.

Next, we hook your starting battery up to a specialized diagnostic machine to test its cold-cranking amps and internal resistance. We clean the battery posts, apply anti-corrosion treatments, and verify that the onboard trickle charger is functioning correctly. If your battery is nearing the end of its life, we will provide a free estimate for a replacement so you are never caught off guard.

Full System Test Run and Load Check

A tune-up is never complete until we actually see the machine perform under pressure. We initiate a full startup sequence, listening closely to the starter motor and monitoring how quickly the engine achieves its optimal running speed. We then simulate a power outage to ensure the automatic transfer switch successfully moves your home over to backup power.

While the unit is running, we measure the electrical frequency and voltage to ensure it is producing clean, stable power that won't damage your sensitive electronics. After the test run, we provide you with a detailed health report and our lifetime workmanship guarantee on any repairs performed. We want you to feel completely confident that your system will activate the moment the grid goes down.

Safety Risks and Unexpected Outages

A neglected engine can develop dangerous exhaust leaks, potentially pushing deadly carbon monoxide gas into your living spaces. Frayed wiring and corroded connections also create severe fire hazards right next to your home's exterior walls. Beyond the physical dangers, a poorly maintained unit simply will not start when the grid fails.

The entire purpose of investing in a standby system is to guarantee uninterrupted power during an emergency. If you ignore the maintenance schedule, you will find yourself sitting in the dark, without heating or cooling, right when you need it the most.

Property Damage and Escalating Costs

During an extended power outage, losing your heating system can cause the water inside your plumbing to freeze solid and burst the pipes. The resulting water damage can easily cost tens of thousands of dollars to repair and completely displace your family. Additionally, a prolonged outage will cause hundreds of dollars worth of groceries in your refrigerator and freezer to spoil.

Minor mechanical issues caught early during a tune-up are usually inexpensive and fast to fix. If you ignore these small warning signs, they will rapidly escalate into major engine failures that require incredibly expensive emergency repairs. Regular maintenance is the only proven way to protect your investment and extend the total lifespan of your equipment.
