"Rarely write reviews, but I had to take the time to recognize the incredible service I received from Green Arrow Plumbing. From start to finish, this was hands-down one of the best service experiences I’ve ever had! I originally called for a relatively simple job replacing a shower head but while they were here, I also mentioned a persistent issue with my main house drain being clogged. Without hesitation, they jumped into action and took care of both problems quickly, efficiently, and with zero mess left behind. They were punctual, professional, and friendly . They explained everything in simple terms, gave a fair and honest quote, and stuck to it. No upselling, no surprises just quality work done right the first time. If you need a reliable, honest, and highly skilled plumber I highly recommend Cornelio. I’ll definitely be calling them again for any future needs. Thank you for making what could have been a stressful situation completely stress free!"

Our project minimum is $5,000. WE DO NOT OFFER COUNTERTOP REPAIRS. We specialize in HIGH END design projects. Mention Angi and claim a $49.99 consultation; a $249.99 value! Over 100 positive reviews! 760-809-7266. We are still open for business and following all safety precautions for COVID19. 2014, 2015, 2016, 2017, 2018 Super Service Award winner on Angie's List! Chris Alan Design is a sole proprietor La Jolla Ca. based design company. We offer a wide range of Interior Design options and partner with some of San Diego Counties most trusted contractors. Christian Delp, our principal designer has 30 years of design experience from which to draw. He has serviced the San Diego area since 2001. Additional email - chrisalandesign@gmail.com.

"In August 2024, my husband and I decided to replace all of our interior furnishings. We originally started our project by working with the “designers” in the stores where we were making major purchases. It took us over 8 months to realize what a BIG MISTAKE that was. Long story short, we called Christian in April 2025. Christian came to our home and talked with us to understand the scope of the project. We wanted to redecorate the family, dining, and living rooms. Christian spent time getting to know us, asking us what we do for fun, and how we live our lives. He gleaned from us that we are adventurous travelers, with a love of the outdoors; he noticed my husband is into music and has a love of classic rock musician hard-cover biography books; he noticed that we both are somewhat minimalistic and that we prefer an orderly space. Christian’s tireless energy over the next 4 months produced recommendations for sofas, artwork, accessories, lighting, area rugs, coffee, end, and drink tables – you name it, Christian thought of it! We needed it all. His recommendations fit not only our lifestyle and our aesthetic preferences, but our personalities. Case in point, during our travels over the years, we’ve taken many photos of the places we’ve been. But these photos lived in our phones – where they weren’t being appreciated. Christian had the brilliant idea to showcase the photos on the wall in the dining room using MixTiles; he also suggested making two huge pieces of wall art for both our entryway and our living room. The result is nothing short of amazing. Christian also brought his crews in for electrical work and some painting. They were friendly, professional, speedy, and very clean. Christian was simply a joy to work with and he made our house not only beautiful, but comfortable, functional, and SO US! He was always available for a visit when a piece of furniture arrived, was always honest with his opinion, and always included my husband. Christian turned what was originally a very frustrating project into a wonderful experience and we are thrilled with the end result. We can’t say enough about Christian’s work and we are proud to call him friend. There is no other designer who will work harder for you, at a more than fair price, with a more than astonishing end result. Thank you, Christian!"

Carini Home Services is a leading 24 hour provider of Plumbing, Heating and Air Conditioning services throughout San Diego County. We offer Repairs, Installations and Maintenance for residential homes. The company is Licensed, Bonded, Insured and is 100% family owned and operated. Our service areas cover all of San Diego County including Central San Diego, East County, North and South Counties. The company's primary product lines include American Standard, Mitsubishi Ductless Splits, Bradford and White, Navian, Noritz and all other major brands of Heating, Air Conditioning and Plumbing equipment. All Carini Heating, Air and Plumbing employees undergo extensive training and are background checked upon hire. You can trust Carini Heating, Air and Plumbing to respect your home, your family and provide you with the 5 Star service you deserve.

"Carini installed my mini splits a few years ago and promised me the world with their warranties. Well, turns out they botched something during the install and all of the refrigerant leaked out. They want $2,200 to refill and re-pressurize the line. Since they cross-threaded the screw that led to the leak during installation, this should be covered under the "Lifetime Craftsmanship" guarantee. Instead, they're trying to charging me a full day of labor to fix their mistake. Support on this issue has been dismal. It's been 16 days since they first diagnosed the problem and I still don't have a timeline for when this will get fixed. I chose Carini because of their warranties and their service record, but its all smoke and mirrors. You've been warned."

Founded in San Diego, "I'll Handle It" is a home grown business that prides itself in its responsiveness to its customers needs.

"Dave was great! The best communication and transparency I've seen in a long time. Dave explained what he needed to do to install the dryer vent and got right to work...NO wasted time. He installed the vent and made sure it was working properly. The vent looks great! Dave is knowledgable, professional, and a nice person. He also stayed in touch, letting me know how soon he would arrive and when he was on his way. I really appreciated that. We will definitely call him the next time we need a handyman."

"When we decided to update and refresh our condo in the Marina District, we got bids from several contractors. We felt that Luis, from R. M. Design, best understood our vision, his bid was reasonable, and his timeframe for starting the work coincided with our schedule. We very much appreciated that throughout the process Luis listened to our ideas while also giving us his expert advice. We know what we like, but he has a good eye and lots of experience. We know that his input and suggestions greatly improved the outcome of our project. We have always loved our place, but now we love it so much more. Also, Luis and his crew worked very well with our HOA association which has several rules and regulations regarding contractors and improvements. We had no complaints from the HOA nor our neighbors.
