Heating & Furnace Contractors in Lake Forest, CA

"Derrick came highly recommended, and I can see why! He was courteous and professional throughout the entire project. I wanted to figure out why my first floor HVAC unit was having trouble cooling (and heating too) and Derrick was able to diagnose the problem quickly, explain it simply, and fix it. He communicated with me and kept me in the loop the entire time, letting me know the timeframe of the repair, when to expect him, and so on. And as someone who works a 9-5 every day, I really appreciated the communication so I knew when to be home! Derrick and Coastal Comfort are my go-to's now for all things HVAC. Highly recommend!"

"They very are punctual and do great work I highly recommend them!"

"Mr. Firuta is well equipped, knowledgeable, and deft at fixing furnaces, plus heâ s a very pleasant gentleman! He notified me when heâ d arrive, and arrived on time. He promptly located the source of my problem and made the necessary repairs, which made my life a whole lot better!"

"everything was perfec and clean"

"I am satisfied w/all."

"The technicians were so quiet during the installation I had to check to see if they were really working. The work area was kept clean during the installation of my heater.."

"This HVAC company is honest and professional, definitely the one to hire. I had another company replace my A/C units last summer and level the furnace, but the system broke down after 6 months. There were several parts of the system that they failed to repair or even inform me about. Reese spent the time to give me a fair and accurate estimate, and even encouraged me to get other estimates before hiring them! Lance the installer came out to replace my old furnace and repair a few parts of the A/C system that had been slapped together, but he went above and beyond to expand my attic access, improve the drainage and bring the whole system up to code. The A/C and heating work great now, and my family and I feel safer knowing that Lance put in the extra time to carefully check everything."

"John with All Pro was outstanding. The water heater was at a rent house my elderly brother lives in. All Pro is the only company that offered to fix the water heater instead of replacing. Came back next morning and repaired. I will for sure use Will's All Pro next year when I replace the water heater. Thank you, Brenda Birdwell."

"Nathan was very helpful through the entire process of installing my Heater. Very professional and great customer service. He even fixed my 2 way switch. His prices are reasonable, best out of 3 quotes I got. I would recommend NT Electric and Heating."

"Outstanding. Duane is the best HVAC professional I've ever worked with. He thoroughly explained the HVAC process and standard yearly preventative maintenance requirements. He also gave me a quick tutorial about my particular A/C unit and explained how to spot any early signs of malfunction in order to prevent future expensive repairs. Top notch, highly recommended."

"I work in the trades, so im no easy critic. My elderly motherâ s furnace went out, and was in need of repairs. Chris and his company were my choice, and let me tell you, was I impressed. Showed up same day within a few hours, diagnosed the issue, He presented multiple options to my mother, kept me updated along the way, and got the repair done SAME DAY!!! My mother was impressed with how clean he was, how much he cleaned after, and even scheduled a follow up for 6 months later to ensure the system is functioning as intended. Will definitely be using Chris for all my HVAC needs and referring him to everyone and anyone that asks!"

"CJ was very professional and thorough with his troubleshooting. He was able to repair my furnace on the same day and now I wonâ t have to worry about my elderly mother being cold at night. I would definitely recommend him to my family and friends."

"We hired McCormick for a bathroom remodel, and the whole process was smooth and professional. Khaled helped us make smart choices on design and materials that worked for both our budget and style. Now, our bathroom feels like a spa every time we step in. I appreciate the quality and attention to detail. These folks definitely know what they?re doing!"

"I recently had the pleasure of working with SoCal Boys Heating and Air Conditioning, and I couldn't be more impressed! From the moment I called for an appointment, their customer service was exceptional. The staff was friendly, knowledgeable, and eager to assist. The technician (Gerry) arrived on time, equipped with everything needed for the job. He took the time to explain the issues with my HVAC system and provided clear options for repairs and maintenance. I appreciated his honesty and transparency—there was no upselling or unnecessary pressure, just genuine advice tailored to my needs. The repair process was quick and efficient, and I was pleasantly surprised by how reasonable the pricing was. My system is now running better than ever, and I can already feel the difference in my home’s comfort level. What stood out most was their commitment to customer satisfaction. They followed up a few days later to ensure everything was working well and that I was happy with their service."

"Jorge and his crew are true professionals. We added on square footage, took out a load carrying wall, installed a steel beam, and remodeled the entire kitchen as well as the Master bath. They did an amazing job and were very timely, responsive, and a pleasure to work with. We will definitely be using them again in the future. We love our new kitchen and master bath!"

"True Air Mechanical is a very great company to work with. Pete our salesman was so very helpful, and patient with us. He was concerned about finding the right system and cost effectiveness for us since we are on a fixed income. He was not a pushy salesman and gave us time to do more investigation. Brian our installer was professional, perfectionist and such a pleasure to work with. He explained all aspects of the system. True Air recommended Carrier system, heat pump and ac unit."
