How to Choose the Right Generator for Your Home or Business
Choosing the right generator is an important decision that can protect your home or business from the inconvenience and potential damage caused by power outages. At Purl's Sheet Metal & Air Conditioning, we provide expert generator services throughout Fresno, Madera, and the Central Valley, helping our customers find dependable, efficient solutions tailored to their specific needs.
The first step in selecting the right generator is understanding your power requirements. For homes, this often includes essentials like lighting, refrigeration, HVAC systems, and medical devices. For businesses, backup power may be needed for computers, security systems, refrigeration units, or heavy equipment. Our team at Purl's Sheet Metal & Air Conditioning can help you calculate your required wattage and recommend a generator that meets your load capacity.
There are two primary types of generators to consider:
- Standby Generators: These are permanent, professionally installed systems that automatically switch on when power is lost. They are ideal for homeowners or business owners who want uninterrupted backup power and peace of mind.
- Inverter or Portable Generators: These are smaller and often more budget-friendly options. While they don’t offer automatic power, they can be great for limited needs or temporary situations.
Other important factors include:
- Fuel Type: Generators commonly run on natural gas, propane, or diesel. Availability and storage options may affect your decision.
- Noise Level: Especially important for residential areas, some models offer quieter operation than others.
- Maintenance Requirements: Choose a system that is easy to service or select a maintenance plan through Purl's Sheet Metal & Air Conditioning for worry-free upkeep.
Our technicians are trained to evaluate your property and recommend systems that provide the perfect balance of performance, reliability, and affordability. Once you’ve selected your generator, we’ll handle the professional installation and offer support for ongoing maintenance and repairs.

What’s the Difference Between Standby & Portable Generators?
When it comes to backup power solutions, homeowners and business owners typically choose between standby generators and portable generators. Both provide essential power during outages, but they differ significantly in function, capacity, and convenience. At Purl's Sheet Metal & Air Conditioning, we help customers throughout Fresno and Madera understand their options and choose the generator that best fits their needs.
Standby generators are permanently installed outside your home or business and connect directly to your electrical system. These systems automatically detect a power outage and switch on within seconds—providing seamless, uninterrupted power. They are fueled by natural gas or propane and can support everything from lights and HVAC systems to appliances and security equipment.
Benefits of standby generators:
- Automatic startup during outages
- Capable of powering entire homes or critical business systems
- Permanently installed and professionally maintained
- Runs on reliable fuel sources like natural gas or propane
In contrast, portable generators are compact, movable units that must be manually set up and started when needed. They are typically powered by gasoline and can only support a limited number of appliances or circuits, making them ideal for short-term or temporary use.
Benefits of portable generators:
- Lower initial cost compared to standby systems
- Easily moved and stored when not in use
- Ideal for powering select appliances during short outages
- No permanent installation required
The main trade-off between the two options comes down to convenience, power capacity, and long-term reliability. For homeowners or businesses looking for dependable, hands-free protection during outages, standby generators are the superior choice. For those who need backup power occasionally or in limited capacity, a portable unit may be sufficient.
At Purl's Sheet Metal & Air Conditioning, our generator specialists can assess your power needs, explain the pros and cons of each system, and provide professional installation and service to ensure you’re fully prepared when the power goes out.

How Often Should You Service Your Generator?
Routine maintenance is essential to ensure your generator is ready to perform when you need it most. At Purl's Sheet Metal & Air Conditioning, we provide professional generator services to homeowners and businesses across Fresno, Madera, and the Central Valley. Whether you own a standby or portable generator, regular service keeps your system running efficiently, extends its lifespan, and helps avoid unexpected failures during a power outage.
Standby generators should typically be serviced at least once a year, though many manufacturers recommend maintenance every six months or after 100–200 hours of operation, whichever comes first. These systems run automatically and may perform self-tests weekly, which still require inspection to verify performance and fuel system health.
Portable generators, on the other hand, should be checked more frequently, especially if they’re used regularly. If you only use your portable generator occasionally, it’s still important to run and inspect it every few months to keep components lubricated and ensure it’s operational.
Key tasks performed during generator service include:
- Changing the oil and oil filter
- Inspecting and replacing the air filter
- Checking spark plugs and battery function
- Testing the automatic transfer switch (for standby systems)
- Inspecting fuel lines, connections, and coolant levels
- Running a full system performance test
At Purl's Sheet Metal & Air Conditioning, our technicians are trained to maintain a wide range of generator models and fuel types. We follow manufacturer guidelines and tailor our maintenance plans based on your generator’s usage patterns and local conditions. With our service, you’ll have peace of mind knowing your system is ready to deliver power when the grid goes down.
We also offer convenient scheduled maintenance plans, so you never have to worry about missing a service interval. Our goal is to keep your home or business safe, powered, and prepared all year long.

Tips to Maintain Your Generator for Long-Term Reliability
Generators are an essential part of keeping your home or business protected during power outages—but like any piece of equipment, they require proper care to stay reliable over the long term. At Purl's Sheet Metal & Air Conditioning, we offer expert generator services throughout Fresno and Madera, helping customers get the most from their investment. Whether you own a standby or portable generator, following a few key maintenance practices can make a big difference in performance and longevity.
Routine attention prevents mechanical issues, ensures smooth startups, and reduces the risk of unexpected failures during emergencies. Here are some essential tips to help maintain your generator:
- Run the generator regularly: Operate the system at least once a month for 15–20 minutes to keep internal components lubricated and to detect any issues early.
- Check and replace the air filter: A dirty air filter can restrict airflow and strain the engine. Inspect it regularly and replace it according to manufacturer recommendations.
- Change the oil and oil filter: Like a car engine, generators need regular oil changes to prevent wear and maintain performance. Follow your manufacturer’s guidelines for frequency.
- Keep it clean and clear: Make sure the generator is free of dust, debris, and rodent activity. Keep the surrounding area clear for ventilation and safe operation.
- Inspect the battery: For standby systems, battery failure is one of the most common reasons generators don’t start. Check battery voltage, terminals, and age regularly.
- Use fresh fuel: Old or contaminated fuel can gum up your system. If using a portable generator, always use fresh fuel and store it safely. Consider adding a stabilizer.
Schedule professional maintenance: Have your generator inspected by a trained technician at least once a year to perform thorough diagnostics and part replacements.
