405 Hvac

405 Hvac handles HVAC work in Irvine. They replace complete systems in homes where the old equipment has run for 20 to 30 years and they also take on ducting jobs when the existing runs need updating. The crew installs units such as two-stage Carrier heat pumps and handles the removal of the old equipment from attics and side yards. Technicians named Sam, Stanley, Robert, Tim and Mike show up for these projects and keep the work areas clean while they finish the job.

Homeowners call them when the old HVAC no longer keeps the house comfortable or when the ducts need to be redone. Reviews describe full replacements that leave the new system running quietly and cooling evenly, with one job finished in a single day. Ducting work includes a free weekend consultation, clear explanations of permit rules and quick updates on contract changes. The same crews handle both the estimate and the install, and customers note the team stays on schedule without leaving a mess.

They respond fast once an agreement is signed and keep communication direct through emails and calls. Pricing comes in clear proposals that customers compare against other bids, and the work stays within the quoted amount. Service covers Irvine and nearby spots, with crews available on weekends for the first visit. Stanley often leads the installation teams and Sam handles the option reviews with homeowners.

The company holds a 5.0 Google rating across 242 reviews, with repeated notes on fair pricing, clean job sites and systems that perform better than the old ones. Reviewers mention the same technicians by name for both replacement and duct projects. DIRT Score 4.9 from 242 reviews on Finds.

“We recently had our HVAC system completely replaced, and the experience exceeded our expectations from start to finish. Our old system was nearly 26 years old, so it was definitely time for an upgrade. Irvine Air were outstanding throughout the entire process and I want to especially thank Sam! He was super knowledgeable, honest, and took the time to explain our options without any pressure. The installation team (including Sam) arrived on time, worked efficiently, kept everything spotless, and the quality of the workmanship was excellent. If you’re looking for a trustworthy company for an HVAC replacement, I highly recommend asking for Sam B at Irvine Air!! Highly recommend.”

“Irvine AC did an outstanding job replacing our 30‑year‑old HVAC system. Stanley and Robert led the team and were extremely professional, knowledgeable, and efficient. The installation was smooth, the pricing was fair, and the workmanship was excellent. Our new system works beautifully and the house feels better than it has in decades. Highly recommend Irvine AC for HVAC replacement or service.”

“I recently replaced the entire HVAC system in my home and obtained three quotes from different vendors, including Costco. I did my best to compare apples to apples, even though each company carried different brands. After carefully reviewing all proposals, I chose Irvine Air Conditioning & Refrigeration Inc., and I’m very glad I did. Their proposal was exceptionally clear, detailed, and professional. Their pricing was fair and competitive. Communication throughout the process was prompt, courteous, and straightforward — no pressure, no sales gimmicks. Once I signed the agreement, they scheduled the installation right away. The crew, led by Stanley, did an outstanding job. The workmanship was clean, organized, and clearly done by people who take pride in their craft. I highly recommend Irvine Air Conditioning. They deliver excellent service at an honest price, and the entire experience was smooth from start to finish. Thank you, Irvine AC.”

“Just finished our ducting replacement project and very pleased I went with Irvine AC and Refrigeration. They came out to do a free consultation on a weekend, which is a testament to their schedule flexibility. They have excellent communication when it came to contract revisions and updates and were very good about explaining the permitting process and requirements. Really appreciated the quick turnaround on emails and project updates. Stanley, Stan, Tim and Mike were very professional, courteous, and a pleasure to work with. They really made the entire project feel as streamlined as possible. Will definitely be reaching out to them as a loyal customer for future HVAC maintenance.”

“Stanley and team did a great job from first estimate to installation. The price for the 2-stage Carrier heat pump was very reasonable for a high quality unit. They removed my 20-year old system without issue from my attic and side yard. Everything was completed in a day. I now have a cold conditioned house with a system I know is efficient and works well.”
