"His work is really good. I've hired him for a few different jobs. Just recently he replaced my security door and a few of my exterior windows. He is now my Go-To-Handyman."

"Daniel did a fine job. Wow, what a Difference. Going from twenty year old Philips tubes TV - very heavy - to the high resolution HD Best Buy "Insignia" 32 inch TV. The old TV died two days ago. This was a big deal in my life, switching TVs. This all got done more simply than I imagined. Set up new TV with take away old TV."

"We were pleased from the very first contact by phone. He was a patient listener, asked relevant questions in a non-condescending manner to get a clear picture of our needs, and he informed me of his schedule and availability. He first came to review each task, took notes and shortly thereafter emailed an itemized quote. Most importantly, he showed up on time and ready to work, we were at ease having him in our home and the quality of his work exceeded our expectations. It also bears mentioning that we'd received estimates for the same tasks from other handymen who inflated the complexity and cost of the job and/or overestimated their expertise (with carpentry and basic electrical work.) Rich fixed things that only needed a slight adjustment that others told us needed time-consuming repair or expensive replacement. He also pointed out things that we could easily do ourselves and money. He was a breath of clean air! We will wait for him to be available to tend to our needs in the future."

"I was pleased that Sean at Comfort Star could check out my furnace problem in less than 24 Hours. Quickly diagnosed the problem in my heater and said he could likely have the parts the next day. He called me back the next morning, said he had the parts and adjusted the price to reflect the up-graded part that replaced the original parts. My house was nice and warm again in only two days, pretty great 4 days before Christmas. Strongly recommend Comfort Star. Thanks Sean."

"Working with Ilan Yosef in Los Angeles was an outstanding experience from start to finish. His team handled our full home renovation with precision, transparency, and professionalism. Every detail was discussed clearly, timelines were respected, and the craftsmanship exceeded expectations. It?s rare to find a contractor who genuinely cares about quality and customer satisfaction. Highly recommended for anyone looking for reliable remodeling services."

"When I purchased my condo, the furnace had a crack in the heat exchanger. James did a great job of installing a new furnace, thermostat, and air scrubber. I have not had a problem with the unit since. I would most definitely reach out again for future services."

"Sean was on time to visit, did a thorough investigation, found the root cause, explained the problem with my HVAC and fixed it. I am impressed with his professionalism and customer serving attitude, great job Sean!!"
