George and his assistant Nathan have both been honest, and they demonstrate a high level of technical skill. George's price for replacing my furnace and A/C system was literally half what the warehouse store wanted--and I've deduced how he manages to be so competitive: Once on site, he never stops working! A lot of other contractors (some unlicensed) will charge whatever they figure they can get, and still do slipshod work. But GP Heating & Cooling is a real keeper. I highly recommend them. read more

GP Heating & Cooling - They install water heaters too. - Heating & Air Conditioning/HVAC Near Me - Yorba Linda, California

To start this , I called to have the service i paid for fixed . They gave me the round around and then said 'any review i leave will be taken down ' their words . I had a service done in March 2026 , prior to Summer rush . The system was low on gas so it was topped up. Yes it worked for 3 days ,but once again it ran hot (than cool) ,I called and they said they didn't warranty their service work as it may have a leak ...well isn't that what i paid you for to check the system ? the Gas didn't disappear it leaked out ! I called another company they came out , found the leak (bad o/ring) easy see it had been leaking and was replaced within 45mins. The whole experience was horrible and I would jope none of you use this company as there is many out their that stand behind their work or at least their morales read more

We have a rental property in Huntington Beach with a furnace not working. I called another company I had used in the past who determined it was a faulty main gas valve. They wanted to charge me $2250 parts & labor. I looked up the part on Grainger and other sources and found that at most was a $500 part. I wasn't going to pay $1750 in labor. They were grossly overcharging for the repair. I found GP Heating & Cooling through a plumber I know. I'm so glad I called them. The valve was replaced for $850 parts & labor. It was a specialty valve, which is why the cost was higher, but the labor he charged seemed fair. I will use GP Heating & Cooling again. Thanks George. read more

ABSOLUTELY EXCELLENT!! I would recommend George and GP HEATING & COOLING without hesitation !! George was at our house yesterday, installing our new furnace and this guy is the best!! He showed up on time with his assistant Ivan, got to work immediately, did an excellent Install, cleaned up and was done in a day installing our new furnace! We are so happy we choose him!! I would also add that I thought his price was very competitive! What I can tell you after experiencing George's work first hand and also having a chance to talk to him, is by hiring George you are getting an absolute top-notch technician and serviceman with years of experience which is exactly what you need. Nothing "fly by night" here. This is quality, serious quality but you can count on! I realise if you're on here you are most likely looking for a heating and cooling service company and you're not sure who you want, it's a lot of money, can you be confident in the guy coming out to your home?, etc, etc.. I put a lot of stock in what others on Yelp say, I use them when making my choices, and this was another case in which Yelpers were right on the money! read more

We hired GP to replace our 50 year old A/c last year. I highly recommend George, he quoted a fair price and didn't try and oversell us something we didn't need. We have solar panels so top tier efficiency not really an issue. He did an amazing job of our system, and even squeezed into the space under the furnaces to make sure it was all sealed up. Posting now in heatwave and our house is so cool. read more

GP Heating & Cooling - Heating & Air Conditioning/HVAC Near Me - Yorba Linda, California

George Pillar is simply the best. He's been repairing my 35 year old AC/Heating for almost 20 years. He just installed a new system and it's amazing - I'm thrilled. He knows everything there is to know about your AC/heating. He's trustworthy, efficient, and a really good guy. One time, it was the Friday before Labor Day, my A/C quit on me and it was 105 degrees. I called George. He came out and replaced my thermostat at 8pm, after he was done with all his other hard work. Like I said, he's the best. Call George, you will be so happy with him and his work. read more

George is the best. He fixed the AC very quickly. Very good service and communication. Definitely highly recommended.

George and Ivan replaced our AC & Furnace, they were great to work with, got quotes from different company with a lot of yelp reviews, and the price is substantially lower. Give them a call for any maintenance service or unit replacement. I strongly recommend their great service. Thank you George and Ivan. read more

GP Heating & Cooling - Heating & Air Conditioning/HVAC Near Me - Yorba Linda, California

See all

Got multiple bids to replace an oversized and improperly installed heater. Not only was GP the most reasonably priced, George spent far more time inspecting our whole system than anyone else and went over all the different options we had to fix our problem. Unlike others, he was not trying to sell us on expensive work that wasn't needed. The actual work was done quickly and professionally. Highly recommend read more

I highly recommend George Piller with GP Heating & Cooling in Yorba Linda -he is the best. He is honest, knowledgeable and very patient in explaining things. Plus he saved me $20,000! I had Econo Air in Brea look at my AC unit, because it was making a noise and they told me it was ready to die at any time and then rattled off several issues with it and then they proceeded to tell me that it was going to cost me $20,000 to replace it (just the AC unit). I then had George look at it and he said there was absolutely nothing wrong with it- that the sound I was hearing was normal. I highly recommend George -Cell 714 694-1402 read more

I have an older AC unit that has been pieced together throughout the years something different always seems to go wrong right in the middle of a heatwave. I've had GP heating and cooling out three or four times in the last five years it's never a previous repair that goes wrong always something new. This week I called GP heating and cooling at the end of the day. The AC was starting to blow warm they finished their scheduled day and came out afterwards that same day. Stayed very late to fix the leak in the system and recharge it. Works better than it ever has, great job GP heating and air-conditioning always honest and will always recommend !!! read more

George came. Saw. And fixed my problem. He stated my system (which is 25 years old) might go at any moment. It might last a couple more years. But that right now it works as it is supposed to work. I asked for an estimate to replace. Lo and behold. It was almost half what had been estimated by a HVAC person working for a large company. I recommend him. I'd give him ten stars if that were possible. read more

Second time I've had them come out to get my 23 year old furnace working right. As before, a simple tune up and explanation of the problem and it's fixed, no up-sell, no BS, just a straightforward fix. George isn't going to try to tell you something that doesn't need to be done, needs to be done. He just fixes the problem and charges a fair price for the job. Thinking about a new system, and if we do it it'll be with GP. Can't I give them six stars? read more

George replaced a thermostat for my parents home a couple of years ago. I remembered he was a straightforward honest guy so when my AC quit in this heat wave I contacted him on a Saturday night. Actually got a response that he could come out the next day! He showed up and did some system checks based on the computer error code. Could not find any issues so he reset the computer to see if it threw the code again but to my luck it started running without throwing a code! George explained everything to me (including how I could reset the computer on my own) and only charged me for a service call! He was concerned about the error code but since all the other components checked out he just said to call him if I have any further issues. What can I say, HIGHLY RECOMMENDED!!! read more

SIX stars would be much better. George and Ivan installed a complete heating and air conditioning system in our previous house. When our new house needed attention, George saved us many thousands of dollars compared to the highly inflated estimate from a much larger, well known company. Pillar gives excellent service for a fair price - something more and more rare these days. read more

I had George come out about three years ago to give me an estimate on a full heating and cooling system. His estimate was the best of the estimates I received. I decided to go with him and have been pleased ever since. It was a clean job with no real issues as of yet. I love my A/C and my heater. The costumer service still continues to today. I was having some issues with my thermostat and I gave him a call on a Sunday afternoon. He answered right away and helped me through my issue. This is a great company that provides great service and products. He was originally referred by a friend and I am grateful that I was able to do business with him. read more

The best in the business! George and Ivan are the best. They were efficient and thorough installing our AC system. Honest and fair price. These guys are highly recommended! read more

Our 30 yr old upstairs AC unit leaked and water came through the ceiling. Called a company that sends out letters regularly. Tech said we needed all new system and show me pictures of the inside of the unit. Have me a ballpark estimate. $$$$$ whoa! Asked some friends for referral to get 2nd opinion. Called George. His openness and candor convinced me. He came out and gave me a good evaluation (and education). He installed a new system and redid some of the original duct work. He and Ivan were very easy to deal with. We are very happy with the service and recommend them. BTW... their cost for EVERYTHING... $$ compared to the other company. And I'm pretty sure the bad pics were not of our AC unit. read more

A neighbor referred George to me and he is every bit as she described. He's a straight shooter and he fixes AC units. Exactly the type of man I needed for the job. Thanks, George! read more

Congratulations! Your search for an honest & reliable heating/cooling professional has ended! GP Heating & Cooling is the BEST out there and you will not be disappointed. George and his team went over-and-above for our family. Our A/C suddenly stopped working on the hottest weekend of the summer. We were melting and miserable. Despite his schedule being completely booked, he squeezed us in on a Sunday. George replaced the broken capacitor on the spot and provided valuable advice on how to keep our system running well. Thank you GP Heating & Cooling! read more

George and Ivan are TERRIFIC!!! They completed a job I thought was near impossible. They are timely, and very meticulous. We had an old floor unit and no central heating. They worked tirelessly to complete the job! We couldn't be happier with their work. George is extremely knowledgable and fair pricing for the work they do. We are so thankful to them and so excited to brave the summer heat with our new AC! We will recommend them to all our friends and family. Thank you George and Ivan. read more

George and Ivan are fantastic!. I've had an on-going problem for the last few years. They have been honest and up front on the issue. It appears to be a manufacturing defect in my AC coil. George has been very diligent and successful in working with the manufacturer to get the components replaced under warranty. I would highly recommend. I referred them to my neighbor and she was very surprised at how fast they responded (and the minimal expense to replace a bad thermostat was incredibly reasonable). read more

George Piller and his assistant, Ivan, installed a new heater and air conditioner in our home. We had had many estimates, and George's was by far the best. George is a perfectionist regarding the work he does, and I love that! He is a no-nonsense, very candid guy; he knows his job, and he does it well. He and Ivan arrived on time, they worked hard, and they finished the entire project in 2 days. When we asked them to return to check the fan, they came out the same day. My neighbor recommended George to me, and I have since recommended him to several others. read more

Never ever ever had a problem that George (the owner) could not fix. HIs helper (Ivan) was excellent as well. My brand new unit was literally 'brand new' in it's system design. Some sort of environmental thingy. Well George was on the phone with the manufacturer over and over again to get to the bottom of what was wrong. Turns out it was the BTU factor that needed to be dialed in. This is noted on my gas bill. That was what he needed to fine tune the burner. (I was sure that it was the thermostat) Go figure. I thought you just turn it on and it works. Well that was the old days I suppose. Not many if any 'pros' would have gone to all that trouble to fix a brand new machine that had brand new workings (Cal. code in a small area of the state of all things). George went the extra mile(s) to get it right. I had another company before him take a try at it without success. SO George IS the REAL DEAL. Honest, personable, and does what ever it takes. Thank you George, and Ivan. Recommend him and Ivan of course, VERY VERY HIGHLY. 5 Stars at least. Ken P read more

BEST CUSTOMER SERVICE I have ever experienced! Not only is it hottest day I've ever seen in So Cal, but when I called GP Heating & Cooling, they came out at 7:30 pm to fix our air conditioner. I would highly recommend GP Heating & Cooling for any of your heating & cooling needs! read more

After another HVAC company who trolled me at Lowes for a "tune-up" on my system said my system was a disaster and needed total redesign and replacement, I called George to take a look. George and Ivan installed the system 8 years ago, nothing was a disaster then, and I trusted George's opinion. The only thing the other company was truthful about was the ducting. It's an old house and had asbestos wrapped, and poorly routed, ducting. George offered a couple of options, and because his prices are very reasonable I upgraded our two-story house to zoning. Once the asbestos abatement team finished, it only took about 3 days for George and Ivan to install new ducting (with balance dampers), zoning with 3 actuators, new thermostat upstairs, and add a new duct in the upstairs walk-in closet. George also generously fixed all the damage the other company left behind after "tuning up" the system. The system now works better than new. George and Ivan are pros at HVAC, trustworthy and reliable, work hard and professionally when on site, and leave virtually no trace during and after the job. Highly recommended! read more

A huge THANK YOU to George and Ivan for taking time out of their extremely busy day yesterday to drive all the way from North Orange county to South Orange county to determine why my vents were blowing hot air. We had not had air-conditioning for about 48 hours and it got up to 91° inside the house at 10 PM the night before they came to do the repair. George determined that it was a bad capacitor on my condenser. This has been one of the hottest weeks of the year and no other HVAC contractor had room in their schedules to come out. That's why I am highly recommending GP Heating & Cooling! read more

Absolutely horrible service. I called first thing this morning to ask if they could come today. I tell him my air is not working, I live in a condo where the unit is in the attic, and is hot as can be. George says he can fit me in at 2pm. I was so grateful. 2pm comes around, George calls and says he is going to be late - around 4pm. I tell him no problem and thank him. George shows up at 4:30pm. I tell him again that it is in the attic. He grabs some tools, comes inside, looks around for 2 minutes, goes outside to get his ladder, and his phone rings. After his call he tells me he can't fix it today and wants to come tomorrow or Tuesday. I told him I can't tomorrow just as I did on the phone. He says he can't do it today because he has to help another client. What am I? Aren't I a client? Goes back into my house, grabs his tools and leaves. Doesn't even look at the unit. Doesn't even give me five minutes of his time to see if he can fix it quickly. Does NOTHING!! And he was rude towards me. It is so hot in this house. If he had told me on the phone he couldn't do it I would have totally understood. But to have me wait for him to show up and turn around and leave. Very unprofessional. I will never call these guys again, and have warned the person who referred them to me. CANNOT COUNT ON THEM!! read more

Just had George and his technician perform service on my A/C. Both seemed nice and friendly, but when it came to the bill and me asking for the $25 off as advertised in the phone book. George's character quickly changed. He actually misquoted the ad, so to avoid giving the discount. I got the ad and showed it to him, then he just said that he couldn't (wouldn't) do it. What he charged was the minimum required for the $25 off, but he was not a man abiding by the company's written word to include the discount. That was disturbing to me. Further, he sent his techie back to the house with the bill and did not bother to come in himself. Disappointed with the lack of courtesy and character switch. I must look for honesty and integrity elsewhere. read more

I called George to check an air conditioner that was not cooling. My wife had also called another firm. The other firm told her they would have to replace the unit at a cost of at least $1500. George pressurized the lines and then came back and checked to find that there was no pressure loss. He then purged and recharged the system and found a problem with a filter that was restricting air flow. It had been there since the unit was installed. George's diligence and thoroughness saved me more than $1000, and the system works perfectly. I highly recommend GP. read more
