Great knowledgeable, professional, and friendly people to work with. Quick response to schedule repairs. Fernando was prompt to arrive at the scheduled time, thoroughly checked for any and all issues with my furnace and made the necessary repairs. Would definitely use them again for my HVAC needs. read more

Miguel always gets right back to us and sees us promptly. We are working with older air conditioners, but he services them and repairs them for us. He is fair and we appreciate his service. Would very highly recommend D.N. air and heat service! read more

Our furnace went out. We were working with a couple of other local companies for estimates. Mike stopped by on a Friday, on very short notice to give us an estimate. By Monday evening we had our house warm and toasty again. Monday morning a team of three very kind and knowledgeable technicians arrived at our home. Marco & Fernando, lead by Kevin were amazing. They were on time, meticulous and respectful. They cleaned everything up at the end of the day. It was as if no one was ever in the house. They worked from 9:30 am until almost 6 pm. They barely took any breaks. By the end of the day, because of Marco, Fernando and Kevin's hard work, our house was fully heated and ready to go. I would highly recommend D.N. Heating and Air Conditioning for any of your HVAC needs. They are fairly priced, efficient and thorough. read more

Got this company assigned to us by the Warrenty company, They did the bare minimum didnt identified all the problems and did everything in their power to take money for the call service and leave without doing anything. When i had to call my own private AC guy who found all the issues in 15 min. complete waste of time and money read more

Today this company was working at my neighbors, and as they were getting ready to leave, I asked if they could come check my pilot light. They were both very friendly and willing to come over and give me a free diagnostic / estimate, and even tried to get my Nest to work. They seem to be very educated and knew what they were doing. However, I think I have a Nest problem lol. I would totally recommend them.Thank you again for your time. read more

Mike provided excellent customer service and resolved my heating problems. I would definitely recommend D.N. Heating and Air Conditioning for all your furnace and A/C needs (maintenance or repair). This is a trustworthy company. I was first connected to them through my First American home warranty claim in 2020 when they replaced my home's tube/vents under the house. Today in 2022, I was lucky to receive SAME DAY SERVICE - because Mike was in my area already and he "made it happen". I'm a happy customer... and I plan to call them in the coming weeks to perform (preventative) MAINTENANCE on both my cooler and my furnace. read more

Mike was great! First, he answered his phone... this was the 6th number I called and he actually answered and called back with a price and availability within the hour! When he arrived early I was pleased and he was totally professional. I had just installed a three room mini split heat-pump system by myself and I was nervous to get it all going. Mike was understanding and came to the service call not sure what to expect, however he was able to find all the small leaks I had made, and had the system up and running quickly! Best service, totally clear about what he needed to do... he knows his stuff! If we need any assistance I will only call Mike in the future! read more

D.N. Heating and Air Conditioning - Mike got it going! - Heating & Air Conditioning/HVAC Near Me - Bay Point, California

We live in Danville, and Mike was first recommended to us by a neighbor. We've been using his services for three years for various heating and air-conditioning needs. He always calls back in a timely manner, gets out to see us fast, and resolves the problem in a great way and at a fair price. He's friendly, knowledgeable, and professional, and he goes the extra mile for us too, which we always appreciate. My husband and I would recommend Mike and his team to anyone. read more

I think the only good reviews must be coming from themselves or relatives. They never call back. Couple of no shows and still haven't gotten the job done after us having to chase them for their business. I seriously don't know how they make any money with the poor service and zero follow up! read more

Super happy with the service i got from Miguel today!!! He went out of his way on a holiday to help me with the problem I had with my AC unit. Really a great service and very knowledgable. I will definitely be referring friends and family with heating/ac issues to them! read more

Mike was recommended to us by a family member and him and his team came by in a timely manner and fixed our issue right away! Extremely professional, knowledgable and a came on time! read more

Max came over to clean up my dryer and pipes in my garage! His job is superb and his personality make his visit just great. The kind of technician i will call when I need help! My dryer and pipes and the whole garage feel so very clean ! Very happy and thank you Max! D N is the best place to call and they have always very good offers ! Marcie Gorham from The Summit in Valencia read more

I found out about D.N Heating and Air Conditioning because of a service request with the house warranty. The first service visit was to check and assess the the HVAC motor and the second visto to replace the motor. I worked with Mike both times, I highly recommend his professionalism, his promptness, his knowledge and how easy it is to work with him. Without a doubt, I will be going back to him for any future HVAC needs. I highly recommend him and D.N Heating and Air Conditioning. read more

This HVAC company has a great team. Kudos to Daisy, Anderson, Kevin and Marcus! They are very courteous, knowledgeable, efficient with their work, and importantly made time to answer and explain well my questions. They are recommended by my home warranty after more than 2 months of terrible experience from another HVAC company. Will definitely use their service again in the future. read more

my AC fan went out and my warranty company assigned my service call to DN.... 28 hours after service assignment I still haven't heard from them to set up an appointment. I left two messages and an email as DN doesn't answer their phone, still NO response. Terrible way to conduct your business. I am now being reassigned to a different HVAC company! read more

D.N. Heating came to fix our furnace this morning. The technician, Miguel, was very polite and knowledgable - he fixed the problem right away. Thanks so much for the heat!! read more

A+ service! Miguel and Oscar were friendly, professional, and knowledgeable. They were able to quickly resolve the issue that was going on with my central heating system and I would recommend them or their company to anyone who needs assistance with their heating and/or cooling system. I am very pleased with their work and will be going to them for further assistance if I have any future issues or am looking to install a new system. Great job guys! read more

Miguel is very friendly and easy to communicate with him. And you can trust. He did a great job every time. and he is always on time.

Highly recommend! My experience so far has been very top notch. We received a quick response to our issue, and more than anything else we appreciate that the technician who came out was very upfront and honest, not just trying to make the most money out of the situation. Mike came by to check out our heater. He was on time, professional and very knowledgeable about our specific type of super old heater. He laid out all the options very clearly and kept in mind our preferences. We will be using them for this and likely many other jobs in the near future. read more

Came on time and installed our smart thermostat in one hour. Very friendly and nice attitude.

Great Service,Quality, Affordable, always on Time and Amazing Personality very professional 100% Recommended.

They came through home warranty to fix our heater system. They fixed the problem really quick. Its been 3 weeks since repairs and heater is working fine read more

DN Heating and Air Conditioning went above and beyond to help us trouble shoot an HVAC issue where our home warranty insurance had failed. The staff to schedule us were very friendly and helpful and the technicians who serviced our home resolved the mystery issue with friendliness and grace. We highly recommend this local team. read more

Mike called to schedule an appointment after being contacted by my Home warranty company. He showed up at the beginning of his time window. He replaced my thermostat and cleaned the coils on my air conditioning. He was in and out quickly, and very professional and friendly. I was very happy with them, and the air conditioning is working great now! read more

Our AC was not working/cooling and we called DN Heating and AC. They were able to come the same day - which honestly made me a little nervous since another company we contacted was 8 days out. Omar came within hours and in the scheduled time frame, he was quick, clean and thorough. We are so thankful and we could not be happier with our fixed AC. We will absolutely use them again. read more

I have had an excellent experience with D.N. They are very comparative in price and care to solve any of your HVAC needs asap. They installed a new Air Conditioner (on my roof) in during a heat wave. They have great communication when it comes to providing service. They care! I also used them for a problem with my furnace, an electrical issue. They nailed it and installed a wireless remote which solved my wiring issue. Very knowledgeable. They will wear shoe booties to save your home from causing dirt issues inside your home without even asking. I recommend them highly. Mike aka Miguel is the best! read more

DN Heating & AC were assigned to repair my furnace through my home warranty company. After lack of correspondence and 2 appointment no-shows, I pulled a plug on them and went with other service provider. I must say they have a really awful dispatcher - really hard to get a hold of and never calls back despite assurances; very unprofessional and inconsiderate of customers' time. read more

Miguel is a superstar! Quick response and knowledgeable service. Called him this morning and though we scheduled for him to come the next day, he was able to come same day and change a part on our AC unit and now our AC works great!! He was honest, did quick work and gave me tips to keep my AC working correctly. Totally would recommend him and call on him again! read more

Super good service. He came out Friday afternoon on short notice before the three-day Christmas weekend to fix a heater that failed to go on. It turned out to be an easy fix and he was finished in less than five minutes. What was most impressive was that he did not charge me. I have had other technicians complete a job quickly and charge me the full service charge. D.N Heating and Air Conditioning will get ALL my future needs. read more

I want to thank Dave from DN heating and AC for his prompt service. I had PG&E come to my mobile-home to light the pilot on my heater. It was lite and he left, I tried to turn it on and much to my disappointment, nothing. I called DN, Dave came earlier than scheduled. He checked the heater, PG&E forgot to turn it back on. Dave did recommend I get it cleaned, which I will schedule an appointment soon. Great service, thank you. read more

Our home warranty company, First American, assigned DN Heating and A/C to fix our A/C unit in the middle of a heat wave. The dispatcher for DN called soon after being assigned and scheduled a technician for the following day. The technician, Jesus, arrived a few minutes early, and fixed the problem quickly and efficiently. He actually checked a second unit to ensure that was working properly as well. Excellent company all the way around and I would highly recommend DN Heating and A/C. read more

They are extremely rude, passive aggressive, and lack any customer service ability. Do not use this company unless you want to be spoken down to, hung up on, and told, "whatever" when trying to explain your needs. They were contracted though a home warranty company and failed to respond or schedule an appointment for days, which left me without air conditioning in 105 degree forecasted days for almost a week. They created excuses about their delay and failed to even provide a report to the home warranty company because they wanted to exercise their "power" to determine whether or not my claim was going to be covered or not. Their technician told me plain and simple that the AC unit needed replaced and then their management/customer service personnel, because of their attitude toward me, decided the technician couldn't file the report for the home warranty because I was forced to use another company to replace my air so I could live in my house again. They lacked any amount of empathy. All the equipment had just been taken out of my home moments prior to their appointment to look at the unit and the technician said he had everything he needed, including pictures of the diagnostics and proof that the AC needed to be replaced. The technician told me it all needed replaced and that he had everything he needed. This company is just mad they're not getting the work themselves and, rather than doing the right thing, they are claiming they don't have what they need for the report. Greedy, rude, inhuman behavior. Do not use. read more

They came out immediately and couldn't have been nicer. Friendly, prompt and understanding. Our issue turned out to be a switch that had turned off and they didn't treat us like morons for not knowing it. They didn't even charge us for coming out. Refreshing to have a business actually treat you like a real human and even like a neighbor. Can't recommend them any more highly. read more

Found them on Craigslist to fix my heater which hasn't been turning on. Made an appointment for today and Mike not only showed up early, but waited for me because I was gone picking up my car from a body shop. Excellent service! He checked my breakers and attic. I have a 3 story townhouse so it's a lot going up and down these stairs. He ended up replacing my thermostat and gave me the best gift all holiday: HEAT! I would totally call again and recommend to everyone. Kind, efficient, and professional. read more

Our home warranty company, First American, assigned D.N. Heating and Air Conditioning to help fix our AC during the heat wave a few weeks ago. They did not call me I had to call them because we needed to try to expedite our claim because we had a 10 week old at the time at home. They scheduled me an appointment for Thursday. That day I recieved a call in the morning to reschedule the time for an earlier time that day I called back to say that would be great and when I spoke to the woman she said that actually they wanted to keep the same time because they had an "emergency" call (another customer with a baby) I explained I had a baby too but it was fine I could wait. The technicians came out that Thursday and they diagnosed the issue took my $70 service fee and assured me that they would expedite this to the best of their ability. I did not receive a call after that for about 5 days so I finally called them and my claim had been closed. They then reopened my claim and told me they would come out Monday July 3rd to fix it. That morning I received a voicemail that they would come out that day and to call them back. I called them back and after talking I told them I was out of town but I would have somebody available to be there when they come to repair the AC. The woman I was speaking to said to me if it would be better they could come out on Wednesday the 5th to fix it, because it was going to be a 2 to 3 hour job, and I said that actually would work even better for us. On Wednesday I never received a call nor did they ever show up to fix the problem. I called my warranty company who then called them and they explain to them that I could not do it Monday because I was out of town and that their next appointment was not until July 20th. I have no reason to make up that they were coming Wednesday so I am unsure why all of a sudden they are claiming I was not working with them...either way my AC is still not repaired and after being given the run around another company will be completing my repairs. Overall I am very disappointed with the lack of customer service aside from the technicians that came out who were very friendly. read more

TERRIBLE!!! I did not have a choice to use DN due to a home warranty policy when my air conditioning unit went out. If I had the option I would NOT have used them. They didn't have all the parts and had to make two trips. Charge an additional xtra fee for some work which I am not sure they did. And spoke limited English. Within 45 days it was not working. A guy came back and said the part inside was bad without even looking at it. Spent two minutes outside looking at the unit to come to that determination. Then the office called me and said it would be another $750 to replace. They didn't warranty any of it! And the home warranty was past 30 days. Seriously?!?! What kind of scam was this???? The gal at the office said it would be two to three days for the part. That was in Tuesday. Never heard back from her again. No problem me ever came back or called to fix. Thank God my neighbor down the street did HVAC work. Much better work too! Terrible work and terrible customer service. If there were zero stars that is what I would give this company. Wow!! Finally heard back a 8 days after initial contact. I hat a joke. DON'T us this company unless you want to pay for below par work. read more

Miguel came by on time as scheduled. We didn't know why are central A.C. stopped working, but after he checked it out, it was fine. It turned out that we hadn't replaced the ceiling filters in years. Miguel was nice enough to tell us this and not charge us thing. I just needed to go down to our local hardware store and pick-up some new filters. I offered him some money for coming all the way out, he said he appreciated that but not to worry, and maybe let some friends know and give him a call if anything needed. Right on, saved us a bundle. read more

DAVID is outstanding. I have used them for heater and the air conditioner. Both times they have returned the car immediately. They show up on time and if running late calls to let you know. They are true professionals. read more

We called D.N to come look at our heater. Mike came and checked it out, verified it was the sensor and cleaned it and was on his way. Very helpful and came in a time of need. Would highly recommend to others. read more

From personal experience after having significant problems with my Air conditioning for the last year despite I have a home warranty account with 1st American home buyers protection, Miguel came out for the first time a couple weeks ago and solved the problem the first time by getting more detailed. Last year I had over 20 visits to my home from 2 different companies dispatched by 1st American and the problem was never solved even though I was told it was. It was an absolute nightmare. However, Having Miguel come by from DN heating and air made me believe that there are still good technicians out there with experience to diagnose a problem, then to fix it without hassle. Thank you Miguel and I will highly recommend anyone to DN heating and air despite they are new in my life but they took care of business. Greatly appreciated and thank you again!! read more
