Whole House Generators Tigard OR

When Pacific Northwest storms knock out power, a whole-house generator keeps your Tigard Or home safe, comfortable, and operational. Whole-house standby generators automatically restore electricity so heating, refrigeration, sump pumps, medical equipment, and security systems keep running without interruption. At Best Owner Direct HVAC & Electrical, we explain how to choose the right system for Tigard homes, what to expect during installation and permitting, the fuel options and upkeep involved, and why timely decisions at this stage deliver reliable protection when an outage happens.

Common Whole House Generator Issues in Tigard Or Homes

Understanding typical pain points helps you choose the right system and avoid surprises:

  1. Undersized generators that fail to handle motor starting loads (HVAC compressors, well pumps).
  2. Improper siting that causes noise complaints, exhaust problems, or code violations.
  3. Incomplete electrical integration or incorrectly wired transfer switches that risk backfeed to the grid.
  4. Fuel supply limitations during extended outages (propane tank sizing, diesel storage).
  5. Lack of regular maintenance leading to failures when you most need the generator.

Whole House Generator Sizing and Selection

Sizing is the most important decision. A proper load calculation determines the kilowatt (kW) capacity you need.

  1. Start with a room-by-room list of essential loads: HVAC, water heater, refrigerator/freezer, sump pump, medical devices, lighting, and any home office equipment.
  2. Account for motor starting currents. Motors can require 2-4 times their running current at startup; that must be included in the calculation.
  3. Consider future-proofing. If you plan to add a heat pump, electric vehicle charger, or expand circuits, size the generator to accommodate projected growth.
  4. Typical whole house systems for Tigard single-family homes range from 18 kW to 48 kW depending on home size and loads, but only a formal calculation gives a reliable number.

Fuel Options: Natural Gas, Propane, Diesel

Each fuel type has trade-offs. Choose the option that fits Tigard utility access, outage duration expectations, and maintenance tolerance.

Natural gas

  1. Pros: Unlimited run time during outages when gas service remains on; low onsite maintenance for fuel supply.
  2. Cons: Gas supply can be shut off in some emergencies; requires utility line and code compliance.

Propane

  1. Pros: Reliable independent supply, suitable for longer outages if tank sized correctly.
  2. Cons: Requires on-site tank and refilling logistics; tank size must match expected outage durations.

Diesel

  1. Pros: High energy density and compact storage; common for larger commercial-grade sets.
  2. Cons: Requires safe fuel storage, periodic fuel conditioning, and more frequent maintenance; diesel can gel in cold weather without additives.

In Tigard, natural gas is commonly available and convenient for standby units, but homeowners who want complete independence often prefer propane with a properly sized tank.

Automatic Transfer Switch (ATS) and Electrical Integration

An automatic transfer switch safely shifts your home from utility power to generator power in seconds.

  1. An ATS isolates generator output from the utility to prevent backfeed and protect line workers.
  2. Transfer switches come as whole-house or selective/critical-load panels. Selective transfer is less expensive and powers only circuits you choose; whole-house transfer powers everything the generator can handle.
  3. Proper ATS installation requires coordinated work between the generator installer and a licensed electrician to ensure correct breaker handling, grounding, and compliance with Washington County and City of Tigard electrical codes.

Siting, Permitting, and Code Considerations in Tigard

Local permitting and correct siting are required for safety and compliance.

  1. Typical requirements include electrical permits, mechanical or fuel permits for propane or natural gas lines, and inspections by the city or county.
  2. Siting rules address setback from property lines, distance from windows and doors for exhaust clearance, noise ordinances, and mounting on a concrete pad or approved base.
  3. Homeowners associations may have separate rules for visual screening and placement. Early review of local codes avoids delays.

Installation Process: What to Expect

Installation follows a methodical sequence to ensure performance and safety.

  • Site evaluation and load analysis to confirm generator size and best location.
  • Final selection of fuel system and permit submission to Tigard or Washington County authorities.
  • Equipment delivery and pad/foundation preparation (concrete pad, anti-vibration mounts).
  • ATS and electrical panel integration by a licensed electrician, including grounding and bonding.
  • Fuel system hookup (natural gas regulator, propane tank piping, or diesel supply).
  • Initial startup, load testing, and commissioning to validate performance under load.

Installers will perform staged testing: a no-load start, transfer under a small load, and then planned load increases to verify the generator handles expected demands.

Maintenance Plans and Testing

Regular maintenance keeps a whole house generator ready year-round. Typical service elements include:

  1. Routine oil and filter changes, spark plug replacement, and air filter checks.
  2. Fuel system inspection (propane fittings, natural gas pressure check, diesel fuel treatment).
  3. Battery condition and charger verification.
  4. ATS operation test and connection inspection.
  5. Exercise runs and load bank testing to confirm reliable operation under simulated outage conditions.

Recommended schedule:

  1. Automatic weekly exercise runs brief and monitored.
  2. Annual professional service including fluid changes and full diagnostic testing.
  3. After any major outage or long idle period, have a service technician perform a commissioning check.

Testing and Commissioning

A professional commissioning verifies every component works together.

  1. Inspect installation, wiring, fuel lines, pad and clearances.
  2. Perform an automated transfer test and full load transfer test.
  3. Use step-loading to validate starting currents and voltage stability.
  4. Document results and set service intervals and parts replacement plans (batteries, belts, filters).

How a Whole House Generator Protects Tigard Homes

For Tigard residents, a standby generator provides practical protections specific to local living:

  1. Winter storms and utility lines down: continuous heat prevents frozen pipes and keeps family safe.
  2. Sump pumps: maintain dry basements during heavy rains common in Tigard winter seasons.
  3. Food safety: refrigeration and freezers remain powered during extended outages.
  4. Health and safety: medical equipment, elevators (if applicable), lighting, and security systems stay operational.
  5. Indoor air: during wildfire or smoke events, powering HVAC and whole-house filtration keeps indoor air cleaner.

Choosing the right whole house generator and following an informed installation and maintenance plan protects property, health, and daily routines during the outages Tigard homeowners can expect.

    Been using them for years after the owner Kevin showed up so fast when our furnace went out one year. Been a fan since! Now, Danny is so great to work with, also. So friendly, knowledgable, fast. You guys are the best!

    Jessie M.

    Danny came out on a Saturday to diagnosis and fix my mom’s hvac unit.   He was able to quickly determine what the problem was and had all the parts to complete the repair right then.  His communication was clear and did a really good job helping us understand what caused the issue.  I would definitely recommend him and will be calling his company with any needs in the future. Thanks again!

    Michael R.

    Fantastic customer service! I had a furnace issue, called late morning and they fit me in for diagnostic right away. Technician was extremely knowledgable, walked me thru everything he found - unfortunately needed a new furnace (was 24 years old anyways), got it scheduled and installed within 24 hours as everything was in the warehouse (probably got lucky on what we needed). Overall excellent customer service, from scheduling to diagnostic, to installation. Highly recommend.

    Brad D.

    WOW! So impressed with so many aspects of this company. We had an animal die under the house in and could smell it coming out of the vents. When I called around, pest control was weeks out and Best Owner Direct was able to come the next day. Our technician, Danny was absolutely INCREDIBLE! Very professional, kind and made sure we had the problem taken care of the same day so we could breathe again! I look forward to continuing to work with them in the future for our HVAC needs.

    Todd & Tiffany F.

    Daniel was excellent, attentive to detail and committed to completing all tasks other installers overlooked. He worked tirelessly into the evening making sure everything was working properly with a water heather install, and he had a great attitude all along.

    Alma H.

    Excellent customer service, great communications answering all of our questions, left the site clean, and very respectful of our space within the house. Arranged to have someone come from the office later in the week to explain how the thermostat works.

    Vinod S.

    BOD is fast, efficient and affordable life save for my client who is purchasing a home with an old HVAC. Best Owner came quickly to help her asses the cost to replace it, and I will continue to recommend their services!
