We had a wonderful experience with Jamison Heating & Cooling when they installed two heat pump systems for us, so when it was time for our one-year maintenance, they were the obvious choice. I called to schedule the service, and fortunately, due to a cancellation, Janette was able to get us in the very next day. Our appointment window was getting close to ending, and I completely understand that service calls can sometimes take longer than expected. Cesar called to let me know he was going to take his lunch break and wanted to check whether we were still available. I really appreciated that he took the time to keep us updated rather than simply showing up later. When Cesar arrived, he first asked how our heat pump systems were working and then explained what the maintenance service would include and whether we had any questions. He was extremely thorough and walked us through his findings along the way. When he finished, he again took the time to ask if we had any questions and made sure we understood everything. We really appreciated Cesar's professionalism, knowledge, and friendly customer service. It's clear that Ryan, the owner, has built a team that genuinely cares about its customers. If you're in Orange County and need service or maintenance for your heat pump system, I highly recommend Jamison Heating & Cooling. And if you have the opportunity to have Cesar come out, you'll be in great hands! read more

Ryan I did get a hold of the company that installed it and they repaired it a couple days later. The real focus here is how your company handled the situation from the start. Your reply should speak directly to how you plan to improve future customer experiences, especially around communication, responsibility, and follow‑through. My recommendation is that you avoid deflecting the issue or shifting the conversation toward promoting your company's warranty or services. What matters most is acknowledging what went wrong and outlining how your team will prevent similar situations moving forward. read more

Looking for a reliable, professional to service your HVAC system, look not further. Jamison has been a go to of ours for many years now. Today Nathan and Daniel came out for our regularly scheduled maintenance check. They were professional, knowledgeable and respectful of my home and property. I especially appreciate their communication and listening skills. They explained what services they'd be conducting and provided opportunities for me to ask questions. They came out and serviced the unit in an efficient and timely manner. Greatly appreciated the excellent service received today! read more

Perfect service call today. System maintenance to make sure all is working for summer. Cesar and Nathan were professional, friendly and very nice to our dog too. read more

Great service! My AC was down, blowing only hot air. They sent out a tech the same day and within an hour, freezing air was blowing. Tech was very kind and thorough, explaining options, pricing, ways to make it more efficient, etc after examining the issue before doing the job. Same day service, friendly and knowledgeable techs, fair prices..call them first! read more

Tech was very informative and friendly. Tech was knowledgeable, informative and wasn't pushy. Efficient service, fair pricing and repaired the furnace after a tech from another company couldn't repair it. read more

I'm giving 2 stars for the guys that came on previous occasions to install the AC and the follow-up appointments. However, Monday we had an appointment for maintenance and the guy that came was too friendly (not customer service friendly). He made me feel uncomfortable. He mentioned 2-3 times that the company didn't give him a phone that he was using his personal phone. Before leaving he said if I have any questions I can text him anytime. He took pictures of the AC unit and wanted to show me, I politely said no because I was keeping my distance. I honestly just wanted him to finish so that he could leave. I'm writing this review so that employees could be reminded to be professional. Thank you. read more

Cesar is the man! Grateful for the careful, honest explanation about everything. Laid everything out there and reasons why or why not. Great service and experience. read more

Good service always. Cesar was great. Explained everything. Knowledgeable. Was very courteous and professional

Our home air conditioning went out this last Thursday which was a hot and humid day. We called Jamison and they sent Cesar out to help. He quickly diagnosed the problem--a faulty capacitor. He ordered the part and installed it and had our air-conditioning running two days later. Cesar was prompt, courteous, and professional. read more

Experience was amazing. Sal came out for the free inspection and was super communicative and helpful. Answered all my questions and more. The job included removal of all old insulation in attic, removal of asbestos insulation around AC Ducting, removal of all old ducting and registers, and a full sanitation and attic-sealing. Replaced with new ducting and high-flow registers, new batt insulation throughout. About half the property has high ceilings, so I know the team had a tough time up there along with the 90-degree weather we had. We also added in a whole-house fan, which has been a godsend (Seriously, get it if you can). Sal and the team went above and beyond during the process. While servicing the AC unit, the team made the call to replace the aging water pump (maybe 20 years old at this point) for free, along with a handful of adjustments to the indoor unit, including a 5-inch filter replacement instead of the normal 1-inch filters, which resulted in incredibly improved airflow without having to mess with the fan unit at all. Overall? I don't have to worry about asbestos anymore, I don't hear rodents in the attic anymore. During these past few months with our usual hot days here in So-Cal, the new insulation, ducting and more all held up very well, and our household could tell the night-and-day difference between pre-service and post-service. Temps were much more stable and the AC is not on 100% of the time during early-afternoon. Sal went further to check and service the exterior AC unit, checking and replacing the capacitor with a voltage-normalizing one to reduce spiky power-usage, along with a wash and flush of the full system. There were a few mishaps, resulting in a few repairs that needed to be scheduled after the completion of the job, as some parts of the drywall gave way during the service. Jamison team scheduled a team to come out and patch all of the issues, and repainted at no cost, so I can't be happier with the service. Original timeline quoted was around 2 weeks, however it took closer to 4 weeks to complete the full job along with the drywall repairs. This was due to a multitude of reasons and coordinating multiple teams, including availability of insulation, so double-check with the team if insulation is in your scope, and account for some extra time just in case. Not the lowest-cost provider of services in this area, but I recommend this team if it fits your budget and considerations, as their work ethic and professionalism is top-tier. Big shout-out to the team, Sal, Jorge, the asbestos abatement team, patch team, and everybody else involved. I was told multiple times during the job that I would get a call or communication from Ryan the owner, but that never happened. I chalk it up to just normal stuff since Sal was always communicative. Sal and Ryan were both very accommodating during the quoting stage. read more

Updated review on a new project. Years ago, Ryan and the Jamison team set us up with a sweet Trane slim line heat pump system. It has been great and reliable. Every 9 months or so, a Jamison tech visits, checks the units, swaps out the filter I provide, and ensures everything stays within warranty and runs smoothly. Back then, I gave a 5-star review, and if I could add 5 more stars, I would. Recently, we needed attic insulation. I requested an estimate, and Alex came out within a couple of days. It was straightforward dealing. He took the necessary measurements and set me up with a few proposals. If you are looking for cheap, low-cost, low-quality options, that's not Jamison. The project took two days. The crew was very mindful of our home, and the house now maintains a steady temperature without the system running for long intervals. The project included a radiant barrier, insulation, an attic fan, and a whole house fan. If you have a project, invest in a relationship, not just a sale. Jamison has you covered. read more

Had service done on our heating and a/c .very professional service..Cleaned unit and made recommendations..I recommend using Jamison heating and cooling system when you need service.. read more

I have been using Jaminson and Heating & Cooling for about a year for maintenance. Sal a lead for the company came out to my house in Fullerton to do maintenance on unit. He discovered asbestos in attic and said they can have a company come remove it. Sal coordinated with the owner and came up with an awesome quote which included upgrade in installation R8 and two free years of maintenance. I was able to finance and nothing down at a really reasonable APR. Sal and his crew ( Marcos and Oscar) completed the job the same day and were very clean and thorough. I would definitely recommend them as a premier AC company in OC read more

See all

They called me regarding an A/C service special. I agreed, and they came out. Everything going okay so far. They offered to replace the air filter with a HEPA filter for $120. I agreed to that. They also noticed our UV light was out and quoted to replace it and relocate it to a better spot. I agreed to the price, and they said they would come out Monday to finish the work as they didn't have the correct UV bulb in stock. New tech called Monday after being late for the appointment and said the part is discontinued and I'd have to replace the UV light unit. He said the cost would be around 5-600 dollars roughly. Mind you, my unit is only 4 years old. So I tell him to send me a quote to my email so I can look it over. Quote didn't make any sense and had multiple items each over 1k. Finally managed to find the UV light unit on the quote but it was over double the price of what he told me over the phone. Tried calling in but kept getting no one. Never heard back from them. I got a voice-mail today stating I owed over $500 for replacing an air scrubber that was never done nor discussed, and for a cleaning service plus air filter change. I tried calling back multiple times, and still have not gotten a hold of anyone. To top it off, now my A/C unit is not blowing out cold air anymore. I have no idea what they did but this seems to be a severely mismanaged company. Hopefully they will call me again so I can get this figured out... read more

I highly recommend this business for the professionalism and expertise my technician displayed. The price for the diag was far more reasonable than the competition I would recommend Jamison Heating & Cooling to all in need. read more

Our original unit (25 yrs) went out about nine months ago. We had Jamison install a whole-house (2-story) Daikin Mini Split system. The installation went fast, just a couple of days. The crew was professional and friendly, and cleaned up at the end of the work day. As time went by, I had questions, and each time I called, I got positive responses and friendly, patient responses (help). They sent out service techs several times to check the unit and confirm its working condition. Being the new type of unit from the old gas style, I took some calls over the months to fully understand how these units work. In short, you cannot go wrong by choosing Madison Heating and Cooling. read more

Ryan, every time one of your team members come out to our home I am compelled to write another review. They are just too wonderful not to be acknowledged. This year Thomas came to help us with a system control issue, and to perform the regular A/C system maintenance. Although there for the air, Thomas also did a quick visual check of the heating system to ensure nothing was going awry. Thomas was charming, knowledgeable, thorough and so respectful of our property! Honestly, it was almost like having a family member assist us. You have done such a great job of hiring and surrounding yourself with technicians that embody your own beliefs and professionalism. Thank you once again for your service! read more

Had an issue with my motor, called up Jamison Heating & Cooling and they were able to get a technician out within a couple of hours. Leo stopped by and was very friendly & informative! He identified the issue while explaining everything to me and got it up & running within a couple of hours. Highly recommend them! I even compared them against others and were the right choice! read more

Our AC broke. they installed a new AC but also diagnosed that our furnace placed in the a garage was not attached to the ducts. there was this drywall box under the furnace in the garage and that was its air intake. They moved the furnace to the attic and attached it to the duct as it was not before. They installed a light in the attic making it easy to access. They are efficient, honest and reasonable. I give them five stars for those reasons. read more

Max provided world class service in his professionalism and helpfulness when diagnosing my HVAC. I had tried to replace the control board myself because my blower motor wouldn't run. He walked me through what the issues were and showed me in detail how the control board and transformer were bad. He also proceeded to walk me through multiple options including repair vs replace on a very old AC unit and was very transparent about costs and benefits of replacing vs repair. Max also did not pressure me to replace or repair immediately like most sales reps would do. This is my fourth time calling Jamison and they consistently provide the highest levels of service and fair prices. Definitely recommend them and Max - 5 stars all around! read more

Great experience with Jamison! My upstairs AC unit conked out midday on a Wednesday and started blowing lukewarm air. Called Jamison Wednesday around 5pm and they were able to come out the following day between 8-10am. My technician was Arturo, who was professional, friendly, and knowledgeable. He was able to figure out and fix the problem in about an hour. I received a courtesy call 30 min before he arrived at 8:30am. I'm very happy with my experience both on the phone and in person! Would definitely recommend Jamison for AC issues :) read more

I have hired Jamison in three locations. Two of those locations required major work. They do excellent work. I'll use them again & again. I would hire them at a fourth location if I had one. Their folks are friendly, knowledgeable, and neat. They do what they say they will do, when they say they will do it. I think my experience is typical and you will have a good experience also when you call Jamison. Bob Hollis read more

Awesome job to Jamison AC and crew!! Perfect install, from start to finish. They took their time and did an awesome job. Thank you guys!!

Leo was fantastic! He arrived on time, quickly diagnosed the issue, and had my heating system running smoothly in no time. Professional, friendly, and efficient--highly recommend read more

Requested a check up for our house AC unit to make sure everything was working properly, Isidro was our technician supervisor, super friendly and was patient with explaining everything about our AC unit and maintenance. Will be contacting Jamison company for all of our future AC needs. read more

I hired Jamison Heating & Cooling Services in 2023 and they did a clean and amazing job ripping out my old heating unit in the hallway closet and installing a brand new one in my attic (after they removed all the asbestos). They also repaired my broken AC unit that had leaking coolant. The home felt amazing through those hot and cold seasons so thank you! Today, the company sent out one of their techs to provide complementary maintenance service on our heating unit. Leo was punctual, professional, and helpful all around so thanks once again! They'll be back in summer for the complementary maintenance on the AC unit so we look forward to having their service again! read more

Tom listened to our needs, checked our previous system, and Ryan, the owner, put together a tailor made package to fit our home and budget. George and Team installed our new system. They were professional, clean, and helpful. All in all, Jamison was a great company to work with. We highly recommend them. read more

Ok, so AC stops working suddenly and you have rental guests coming in 4 hours and you live in So Cal where the temps can get really hot. It's a Friday afternoon and you need help, good help. And you need it fast. Make one call - to Jamison. They came out quickly, made the temporary fix in time for guests and then came the following Monday to provide the permanent fix. Oscar came on Monday and did an exceptional job at repairing, and improving the AC unit. Thank you guys for being there. I feel so much better knowing I can call you and count on you to take care of me. read more

Without even looking at my AC unit, immediately was recommended to replace the entire thing. Tech did not listen to my requests. He went to his van and quoted the highest price possible to repair my unit: $4,200.00. Including an item that was not damaged. I went with a competitor that only charged me $350.00 and had it working in no time. No add on charges. Very disappointed in Jamison service. How is it possible to go from $4,200.00 to $350.00?! That's a huge difference. read more

I was able to get someone over to my place asap to diagnose my ac unit. They were honest (and business wise) and offered a new unit but I went the route of just refill of freon. So far it's cold and amazing. So my AC blows cold again, for about $200 which isn't too bad, I got it refilled. read more

*** $68 A/C Cleaning Nearly Cost Us $1,562 *** Used Jamison's Heating & Cooling (Jamison AC & Furnace Repair) for a $68 A/C cleaning and tune-up (never got the evaluation report or air flow analysis advertised on their website) for our A/C system which was working fine and made no unusual noises. Did not need this service, but they left a flyer at my door and it seemed a "nice to have" luxury with baby at home and temps in the 90's. On 7/18/23, on the first phone call with the owner, Ryan, he lied that the owner was a different Ryan. Even now, never understood why he did this. On 7/19/23, their technician, Arturio "Art", left an overshoe (shoe cover) insulating and choking the blower motor. Unclear if due to incompetence or if intentional. Thank goodness I checked inside the furnace myself. Motor screeched loudly all afternoon until Art came back to remove the overshoe. The blower motor then buzzed very noticeably for 5 days and then died on 7/24/23. On 7/25/23, Art quoted $897 to replace the blower motor ($800 for a motor that costs $178.55 from their supplier + $97 labor). Given what happened with the original service, Ryan agreed to replace it at no charge and refund my original $68 (he reneged and never gave this refund). While doing the replacement, he snapped the head off the bolt in the collet of the blower wheel, and never told me. Anyways, the new motor wouldn't turn on. Art wired the motor all wrong (wrong High and Med-Low circuits, and reversed rotation), refusing my pleas to double-check and wire it according to the chart on the box it came in. Unclear if due to incompetence or if intentional. Instead, he poked around the furnace's transformer (which was actually outputting voltage) and relays with a multimeter, and said they needed replacement for $597. With this diagnosis, Art and Ryan tried to blame me for having to replace the blower motor unnecessarily. Conveniently, my original motor couldn't just be put back because Art cut the wire leads too short (and the blower wheel was now stuck on the new motor because he sheared off the collet's bolt, which he hid from me). After negotiating and with my family now being in a hot and desperate position, Ryan said he would have technician Joseph "Joe" come the next day between noon-2pm and replace the transformer/relays for $305. Joe never showed up or even called during that time window on 7/26/23. With my baby suffering in the heat (again in the 90's) and desperate, I reconnected the blower motor wire leads according to the manufacturer's instructions, and the blower motor began working immediately (and still working fine as I write this review). Thank goodness I opened up the furnace and fixed what Art had messed up. Art had misdiagnosed that my transformer/relays needed replacement, and he wired the new motor (needed because the overshoe was left on my original motor) completely wrong. Unclear if due to incompetence or if intentional. I wrote to Ryan describing my experience with his company, the technicians, the mistakes that were made. and that the average homeowner would have ended up spending over $1,500 on what was supposed to be a $68 clean/tune. If Joe was on-time, even I would be cheated out of the negotiated-down $305 for them to replace my working transformer/relays, on top of the $80 I paid/tipped for the initial clean/tune. Not to mention that when my original blower motor got killed off and the A/C kept running, my A/C condenser/compressor/lines could be damaged, which would cost thousands to replace. Guess this is how Ryan and Jamison is "Taking Care of People... one step at a time" and being better than "big corporate company's sales processes and agendas." Instead of apologies, explanations, or even just lip-service (polite excuses), Ryan responded with personal attacks and finger-pointing. Real classy. So much for Ryan and Jamison being "Your Friendly Neighborhood HVAC Pros." Wouldn't be surprised if Ryan or his staff respond to this review with more of the same toxicity (as they did to another Yelp reviewer). read more

Excellent service! Miguel, Mauricio and Marcos were amazing! Very professional, clean and proficient. Got the job done well and fastExtra shout out to Miguel for his hard work and Janet's attention. Would recommend them in a heart beat. Thank you!!!! read more

Max came and did a great job diagnosing our problem. He provided a detailed review of our HVAC and lots of options to improve its efficiency. Great service! Highly recommend! read more

The duct work and installation was completed as quoted they arrived early and kept the work areas cleaned at each departure.

Jamison is best HVAC local company we have used. They respond quickly and have reasonable prices compared to the other contractors we were referred to by our insurance company and found on yelp. They removed our old package unit and did a new split system for way less than 3 other vendors, including Costco's vendor. They use well known and quality equipment too, our family is happy and warm now. Ryan worked with us and Jorge got it done. read more

I had an appointment with Dan from Jamison AC cooling and heating. Upon his arrival Dan introduced himself and shared the process of his inspection. He politely wiped his feet upon entering my condo. He inspected my central heating and cooling equipment very thoroughly answering all my questions completely. He took his time and never rushed. I was very pleased with his service and look forward to working with him and Jamison, AC and cooling in the future. I will definitely recommend Jamison AC and cooling to all my family, friends and colleagues. Thank you read more

Joseph is the man. I had a little leak in my attic and he came over and fixed it up real quick. I have dealt with these guys a few times and they have always been super honest and fair. Great customer service. read more

Very nice and professional. Was thorough and helpful in suggestions regarding what to do. Will definitely call back for any future problems!

I can't sing the praises of Jamison (and specifically Sal) enough. I had them out after another HVAC company fleeced me to have freon added to my newish mini-split system. $800 later - that wasn't the problem and was still blowing hot. So I tried Jamison and after a thorough deep cleaning of my unit and three registers - it's been working perfectly for a year now. Please don't go to those other "bros" and call Jamison. read more
