Jamison AC & Furnace Repair - Serving Fullerton and all Orange County 3519 West Commonwealth Avenue, Fullerton, CA 92833

"Sal was very professional and explained every step of the tune up and maintenence process. He was able to determine I had a small leak on the roof right away and showed me where and how to fix the issue. He was honest with results and recommendations."

"We have had great experiences with Jamison. They’ve installed 2 systems for 2 of our properties and also do our yearly maintenance. They were very knowledgeable, very respectful of the homes (always cleaning up after themselves and wearing booties) and very pleasant to work with. Highly recommended!"

"Great technicians. Always willing to answer my questions. I buy a maintenance contract every year and Ryan does the scheduling. They are on top of it. Word of advice: Buy a maintenance contract. HVAC systems are expensive! I have two attics and they check the ducts in each one. So happy to have found them."

"I purchased the HVAC system from Jamison AC Furnace & Repair last year. Their prices were competitive and Griffin the Sales rep was great! I needed to have a few things corrected / changed with my system Ryan was very responsive to my needs. His crew have been very helpful and professional in getting my HVAC in top notch shape. I would recommend this business"

"I am very happy with Jamison Heating and Cooling. I used them two years ago to replace my AC, gas furnace, and ductwork with a single new heat pump and new ductwork for a 3-zone system. They were professional and did quality work. I am very happy with the result. Recently my church needs to replace two HVAC systems. I got two quotes from two contractors including Jamison. Ryan, the owner of Jamison, was very responsive and professional, and he was able to come to give an estimate right away. Better yet, he was able to give us a very good church discount, and as a result his price was way better than the other contractor’s. Ryan is a pleasant person and very easy to deal with. We hired Jamison that same day to do the job. Ryan sent several workers right next day and they worked the whole day to finish the job that day. Again, it is a quality job well done. In addition, our church had a third HVAC system where the condensation pipe had a leak that’s causing water damage to the ceiling. For a low price Ryan sent a technician Brandon to diagnose the problem and the price also includes thorough cleaning and maintenance of this third HVAC system that probably had never been maintained for 27 years. Brandon spent many hours. He found all the problems and cleaned and serviced the system. He was very professional and patiently described to me all the problems he found and even patiently explained to me how those problems happened. Overall I have very good experience with Jamison Heating and Cooling. I would highly recommend them to anyone."
