5 Steps to Finding the Best Plumbers in Corona California

  1. Reputation – ask friends and family, check online reviews in Home Advisor, Yelp, and Google. Do they have references you can call? Be sure prospective contractors have lots of customer reviews on several platforms. If you see a bad review, be sure to take notice of how the business responded.
  2. Check their contractors license and insurance, all of which is easy to do online at the CA Contractors State License Board. See ours here:
  3. Communication – how easy is it to connect to a real person at the company? Do they respond quickly to messages? How’s the mojo when you talk with them? What’s your gut tell you?
  4. Project Profiles – ask to see photos and case studies of previous work and provide references if your job is big. Do they have any before and after photos for jobs like yours?
  5. What’s the cost? Are they charging a flat fee for the job or an hourly rate, or hourly plus parts, etc.? You need to know. The best deal may be a flat rate for the job, that way you know exactly what you’re in for.

About Corona, CA

Corona (Spanish for “Crown”) is a city in Riverside County, California, United States. As of the 2020 census, the city had a population of 157,136, up from 152,374 at the 2010 census.

The cities of Norco and Riverside lie to the north and northeast, Chino Hills and Yorba Linda to the northwest, Anaheim to the west, Cleveland National Forest and the Santa Ana Mountains to the southwest, and unincorporated Riverside County along the rest of the city’s borders.

Corona is approximately 48 miles (77 kilometers) southeast of Downtown Los Angeles and 95 miles (153 km) north-northwest of San Diego. Corona, located along the western edge of Southern California’s Inland Empire region, is known as the “Circle City” due to Grand Boulevard’s 3 mi (4.8 km) circular layout.

It is one of the most residential cities in the Inland Empire, but also has a large industrial portion on the northern half, being the headquarters of companies such as Fender Musical Instruments Corporation, Monster Beverage Corporation, and supercar manufacturer Saleen.

== History == === Etymology === Corona is Spanish for crown or wreath.

Originally called South Riverside, citizens wanted to distinguish their city from the larger city of Riverside to the north. When it came time to incorporate the city a number of different names were considered, but the name Corona was chosen to play upon a unique feature of the city, the one-mile diameter drive that circled the center of the town.

=== Early years === Corona was founded at the height of the Southern California citrus boom in 1886, and is situated at the upper end of the Santa Ana River Canyon, a significant pass through the Santa Ana Mountains.

Tim was available to answer my text message on a Sunday after a long 4th of July weekend and set us up for a service call within 48 hours. Tim f1ixed our air-conditioning problem and gave us good advice on maintenance and future repairs/ replacement options to keep our 22 year old system running. Definitely will use Tim and RT Olson going forward.
