We called Rob on a whim a few years ago after our HVAC company had a ridiculous 3 week wait for service. Since then we've never looked back. Rob and his team are efficient, honest, and do a great job. Rob talks to me exactly the same way he talks to me husband and if you're a housewife who deals with contactors a lot you know how rare that is! He explains everything thoroughly and makes me feel confident in the work and the price. read more

Hart Heating & AC Cooling - Wall mounted A/C & Heating Unit - Heating & Air Conditioning/HVAC Near Me - Garden Grove, California

These guys do good work, they're reliable and very good at what they do! Definitely my go to guys when I need air conditioning services done. Very affordable for the quality of work they do. They saved us when our a/c was not turning on and it was 102°f outside. I would recommend them to everyone I know! The thermostat they installed in my house can be controlled from my cell phone when I am away, and I can change the background colors or themes that are on display! My hair stylist at Next Chapter Salon tends to send me home with purple hair so now my thermostat can match! Love it! read more

From start to finish EXCELLENT SERVICE! We got a lot of quotes from contractors to install our central air. Rob was the most professional and knowledgeable contractor I have ever dealt with. Rob and crew work hard and get the job done right. No mess no fuss. Thank you Rob read more

I'll start by saying I didn't pick Hart Heating and Cooling to install my whole house system, it was my general contractor... Rob installed our whole house system two years ago when we did a remodel it included everything duct work, furnace, condenser etc. And it has been great, hot when you want hot, cold when you want cold. The bills dropped by having a more efficient system and everything has been great. Couldn't be happier. Turned the AC on for the first time this season the other day and it smelled a little dusty not bad but made me think hey I better service this thing instead of just ignore it. Called up the office and they couldn't have been better. Got me an appointment the next day, Rob showed up cleaned the system and showed my wife how we can do future service on our own so we don't need to be charged for basic stuff. He didn't charge us for this return trip since we never had a chance to review the system during the remodel. My only complaint, Rob just does heating and cooling. If I could have someone who has this kind of service for my electrical, plumbing, car etc that would be great but for now I'll have to settle that Rob just does heating and cooling. Thanks for being awesome. read more

Our condo AC unit was on its final leg, and after being sick of pouring more money into it only to have it break down a month later, we decided to look at replacing our AC unit and furnace. After several quotes from companies, we reached out to Hart Heating and Cooling via yelp. Rob came out the next day and gave us a quote that was under the other companies and was additionally more detailed on what work was to be done. We ended up going with Hart and am glad we did. The install was done in a day, and the employees kept things clean while they were working. Rob even included a few things to keep my condo association happy when it wasn't in the scope of work. My wife and I are extremely happy with our new AC and will definitely be recommending Hart Heating and Cooling to anyone in need of honest and detailed HVAC work. Thanks Rob! read more

We've worked with Rob for years with many rental properties we manage. He is responsive and very knowledgeable at what he does. I recommend him to anyone looking for an excellent HVAC company. read more

Tried calling the guy twice, never picked up his phone and second time hangs up on me? He could have called me back. What kind of service is this? I'll try another company for my business. read more

Rob is the guy you're looking for! My husband and I just moved to Orange and our AC stopped working during this week's heat wave. I called Rob in the morning and he was out at our house by 2pm the same day. My husband has a friend in the AC business (they were on vacation and couldn't come out) and could tell that Rob really knew his stuff- he was friendly, helpful, and didn't try to up sell us on anything. He was knowledgable about the AC unit and could tell it was just the capacitor not working. It was a quick fix and we have our AC back on already! He is a lifesaver because our 3 month old baby would not have been a happy camper in this 100 degree weather. If you want an honest, reliable person to handle your AC issues, definitely call Hart. read more

I searched and compared prices and Hart is definitely the best. After listening to different technicians plans and expertise, Rob obviously had the MOST knowledge and it was a clear choice for me. What truly separate Hart AC and Heating from the rest is Rob and his team's professionalism and expertise. Besides Rob, Matt and Kraig were very polite, friendly, and very knowledgeable. They had me involve in the project to ensure my happiness and my family and I are very happy with the results. I definitely will recommend them to my family and friends. Also, Rob honors the men and women that served our wonderful country by providing a discount. Thank you Rob, Matt, and Kraig !!! read more

I called these guys out about 6 weeks ago because my AC wasn't cooling very well. I placed my call at about 6:30 PM. The owner, Rob, answered the phone and came out the next day! He charged my system up with missing Freon. At the time I got a quote for all new duct work and vents (My house had original Heat only ducting because the AC was added on). My kitchen and living room are on the hot, west side of the house and my current set up just wasn't doing the job. A less scrupulous company may have tried to sell me a whole new HVAC system! HART just completed my new bigger duct work today and I'm staying cool (in the kitchen) and their prices are very reasonable! read more

I can't recommend these guys enough. We originally had planned to move our air conditioning unit, and Rob came out promptly and leveled with us and was completely honest, explaining that the unit was already in the best location in our back yard. It turns out that we decided not to move the unit, saving us probably $3000 in parts and labor. It is rare to find someone who is honest in this line of work, and I'd definitely call him first if I ever needed anyone to service my AC unit. read more

HART Heating and Cooling is Absolutely excellent. I have used them 3 times now and everytime they have been On Time and Professional. Rob, the Owner, is extremely knowledgeable and friendly. I thought I needed a new unit this 3rd time so I called Hart Heating and Cooling and Rob came by. He took a look and said I didnt need to replace my unit. Just needed to replace 2 small parts in the unit which he had in is Truck. Saved me a lot of money by fixing my problem instead of trying to sell me a new Unit. I Highly recommend Hart Heating and Cooling. read more

I highly recommend Rob and his team for all your HVAC needs!!! I'm so glad that my cousin recommended me to Hart Heating & Cooling. Before I finally gave Rob a call, I had already got quotes from another business. Rob came out to take a look at my house and explained in detail to me what needed to be done and what I could get away with as far cost savings. At first Robs Quote was about $200 more than my first quote but after reading the reviews about the other place and I decided to pay a little more to go with Rob for peace of mind based off of my cousin's recommendation. Little did I know, Rob was actually close to $500 cheaper because the brand that Rob quoted me was actually better than the other quite, Rob also Included a hideaway WiFi module so that I can turn it on and set it to any temperature I like remotely! Rob and his team did a great job on the install, they even went into the crawlspace under the house to run the electrical instead of running it along the side of the house. Everything was nicely hidden! Thanks Rob and your crew for the amazing work! read more

One of only a few companies that would even call me back during this recent "heat wave". They responded immediately and were actually earlier than the window is was given (and they called prior to showing up). Once here Rob was very professional and thorough in his inspection of our system. Once the problem was observed, it was fixed in no time, and he was right in the price range we were quoted for our service. Thank you to both Hart, and Rob as they have new customers!!!!!! Fair, Honest, and Forthright are all very hard to find these days, never mind in 1 company. Thank you, read more

Rob was able to come out and service our Furnace on the same day we called. The computer had died and he was able to acquire and replace it in the same day as well as set us up with a better filter that I now know how to replace myself. He also explained everything he was doing in great detail and even gave us a few pointers about our AC. It was overall a great experience and we will definitely be return customers for all of our Heating and Cooling needs. read more

I highly recommend calling Rob Hart for your heating and ac problems for businesses. Super responsive and knowledgable and he helped us save a bundle as well. We called in the evening and were lucky that Rob could come out the very next morning. I got up on the roof in CDM and Rob didn't even mind (or charge me extra for) me watching and asking some questions. Great work, reasonable prices and a nice guy. read more

Great customer service followed up by excellent work!! Rob is on it and has a complete understanding of everything I needed done. Was able to get the job done in one visit and was very friendly. I highly recommend Hart Heating & Cooling. read more

Rob is great, I needed a second opinion in regards to another ac companies $3,000.00 quote. Rob was at a neighbors house doing work. I asked him to look at our unit and give me a second opinion. He came over spent 30 minutes on it and had it up and running again. All that was wrong was a cheap $20 part. Thank you for your honesty Rob. read more

Wall heater was shutting off and not restarting. Called Rob Hart. First call, he thought he had repaired the heater. When the problem persisted, called him out two more times. Last time, he replaced the thermostat and said if problem persisted the heater would need to be replaced. Tried to get him to come out to replace the heater. No call back. I found from a local supplier same manufacturer of heater, brand new heaters. I was willing to pay for heater and will call for heater to be picked up and installed. No response from this company. I'm disappointed that I didn't get the call back. Had to get someone else. read more

Nothing about any of the jobs I have had done by Hart Heating and Cooling were simple jobs. My upstairs condo with my cooling unit in the neighbors backyard was a challenge in itself not to mention my yapping dogs that jumped all over them. Yet HHC were always friendly, hardworking, and knowledgeable. They went above and beyond to make sure every detail was taken care of. I highly recommend them and will use them wherever I live for my heating and cooling needs! Thanks Guys!! read more

Hart Heating & AC Cooling - Heating & Air Conditioning/HVAC Near Me - Garden Grove, California

See all

Excellent job! I can easily recommend Rob to friends and family in need of his services. My house had no AC and the original duct-work and furnace (1964). Rob arranged for the abatement company to take care of the old duct-work and made quick work of installing the new system. Now I just wish I upgraded sooner. Rob and his team are very professional. Arrive on-time, clearly explain my options and the progress of the job, and take extra care to make things as energy efficient and ascetically pleasing as possible. I couldn't be happier with the outcome of the job and am very glad I went with Hart Heating & Cooling. Rob is VERY knowledgeable about this field. At times I felt I was having an energy consult done on my house. Rob spent a lot of time explaining my options and talked about how to make things most efficient while staying within my budget. I swear he can start a side gig doing consulting, he knows what he is talking about! Overall very pleased with every aspect of the job. The communication, the time frame, the price, and the outcome were excellent. Thank you Rob and your crew (Pete and Jami thanks for taking great care and doing such a good job). read more

I called for a repair on my Furnace. I liked him from the first call back. I had called 2 others highly rated, Hart called me right back, went out of his way to get to us same day. He provided honest advice, repaired the furnace at a great price. Gave me good advice on pm things i could do to troubleshoot it in the future. Definitely will call him next time I need ax/ heating advice and service. read more

Rob's prices are very reasonable. He is trustworthy and very knowledgeable about systems and what actually needs to be done. I would highly recommend Hart! read more

This was my second time using Hart and once again they've exceeded my expectations with their knowledge of the equipment, best practices and overall affordability. The first experience was having a split unit setup up our server room, he was on time and the installation was hassle free. He even took an extra 30 minutes to repair the drywall from where the duct had to be ran and made sure to vacuum and wipe the area clean. By far my best experience with any kind of repair technician. After such a wonderful experience the first go around, as soon as my home central air started acting up and on the hottest day of the year no less, I called him immediately. The tech went completely out of his way to accommodate my not getting off work until after 5pm which was absolutely stupendous. He trouble shot the unit and in under 30 minutes we were back up and running. I can say for a fact that I will be calling them again the next time. read more

Hart Heating & AC Cooling - Running a cool 78 when it's 90+ - Heating & Air Conditioning/HVAC Near Me - Garden Grove, California

Excellent service! When I had an issue with my AC and they came out quickly and took care of the problem. I wish more contractors would be providing that level of customer service. Thanks Rob read more

After speaking to Rob, I'm changing my rating. He explained a couple of things that made me feel satisfied. I have since delayed this project but will go back to Hart Heating and Cooling first to requote this. read more

I just saved $12,000 with these guys!!! We had a very old HVAC (1978). We needed ducting, a/c and heating units replaced and drywall repaired where our old unit had leaked. Our first estimate was over 20k! These guys came in at 1/3 of the price and they were super fast responders. I figured that I would have to compromise on quality or service but NO! They were friendly, clean and on time. They even coordinated the install with another company to remove the old asbestos. Our new system is quiet and they added multiple new vents so that our second floor can be cooled without freezing on the first floor. My Mom is going to need a new a/c unit soon and she's going to go with these guys as well. read more

Great service! AC stopped cooling a couple days ago. Saw the great reviews and also recommended in the neighborhood. Called to ask for a service quote and ended up booking a service for 2 days later. Rob came out and was quick at finding the problem. After fixing it, he took the time to show my husband and I the at home maintenance steps. Very honest company. Definitely recommend! read more

Rob is the best! We called him in the morning and he had our AC up and running by 2pm the same day! A life saver in this heat. He went above and beyond. Honest, A+ service to say the least! read more

Hart Heating & Cooling is fantastic!! A property manager that handles lots of homes recommended them to me when my A/C stopped working on yet another super hot day. She said Rob (the owner) is the best and I totally agree. I had called another company first who said it couldn't be fixed and that I needed a new system and quoted me some high price. Then Rob came (on time), and quickly diagnosed the issue and fixed it! He explained what he was doing every step of the way and told me my various options. He really knew his stuff, was honest and friendly, and gave me a really fair price, and a great quote for if it does fail again and needs to be replaced in the future (my A/C is very old - 20 years - so it's bound to need replacement sometime). It's still working great since he fixed it. It's so hard to find contractors who are excellent at what they do and who you can trust; he is someone I would recommend to everyone without hesitation. read more

Really appreciate Rob's professional integrity. Got to our house as soon as he could considering the heatwave had his workload filled to capacity and beyond. Could have told me I needed some hundreds of dollars replacement part and I would have believed him, but he fixed us up for the service call plus $30. Some blown fuses, some other small fix, cleaned off our unit and gave good advice about filters. Couldn't be more satisfied, and definitely will keep Hart Heating and Cooling in my repairman go-to file. read more

We recently bought a house with a swamp cooler and an ancient busted heater and Hart Heating and Cooling replaced both units along with all the duct work. Now we have central AC and heat and couldn't be happier! They were fast, professional and affordable. Hart Heating and Cooling was hands down the best AC/Heat company I've ever dealt with and highly recommend them to anyone who has AC/Heat needs. THANK YOU GUYS!!! read more

Rob came out to the house and diagnosed the issue with a simple wiring problem. Minor and I mean minor cost. A day later the heater wasn't working again. He came right back out and our thermostat was the problem. Again, he fixed it right away for a very minor fee. His business card it on my refrigerator and I can tell you he is getting referrals from me like crazy. Honest and I can tell you that when it comes time to remodeling our home Rob is going to be there! I can't think of anyone else I would trust. read more

We have used Rob at Hart Heating &Cooling multiple times. He has replaced both our air conditioning unit and our furnace and we couldn't be happier. The nice thing about this company is that they don't try to up sell you on services you don't need. Very responsive to any questions I had and stands behind their work. Highly recommend this company to anyone. read more

I own a business in OC and needed a long overdue tune up to the air conditioners on the roof. I was looking for a referral from a friend but could not get one, so I jumped on YELP and liked what I saw from Rob's company, Hart Heating & Cooling. WHAT A POSITIVE EXPERIENCE! He made an appointment for the next morning and was there on time, something I rarely see in service technicians! He was very straight forward and explained everything. I now have a new AC guy and will recommend him to others. I look forward to having him back for yearly maintenance! Thank you Rob! read more

Rob is amazing. We are very fortunate that he was able to come to our house to get us an estimate on what to do with our unit. He was honest, clean and pleasant to deal with. I would recommend him as someone that is respectable and not just out to make a buck. read more

Rob and his team provided us with good, quality work. He was a referral from friends, and we were excited to also see his amazing review history on yelp. I'm here to add another 5 stars due to his customer service, and his honest work ethic. He didn't try to do any pressure sales, only provided honest feedback. He showed up when promised. His team was incredibly respectful. Again and again I'd hire him! read more
