The only company willing to help with our older unit! So thankful and grateful. They even offered to come take a look for free when others said no one would repair it. Suzie in the office was kind and helpful from start to finish, and Juan, the technician, did an awesome job. He was on time, quick, and efficient, and fixed it right on the spot. Thanks a million! read more

Juan diagnosed my problem, and although it wasn't good news, I am confident his conclusion and advice were good.

9/30/25 I would like to update my review of this business. Michael and his team was very gracious and reached out to us repeatedly to make things right. His business and work ethic are commendable. There are very few businesses that have this level of customer service and follow through and I would hire them again for this reason. Thank you Michael for fixing the issue. read more

Zach was the technician assigned to our appointment today. He was kind, courteous, and ready to work upon arrival. He communicated his findings clearly and made recommendations for our system. Also followed up with his notes and additional information about the customer service program from the company via email. Thank you for the wonderful service! We highly recommend Smart Heating and Air Conditioning for all your HVAC needs! read more

The technician, Juan Rodriguez was pretty knowledgeable, thorough and made the proper recommendations to solve the AC issue. I really recommend Smart Heating and Air for your AC situation. Thank you Juan Rodriguez! read more

My tech, Christopher, was prompt, professional, courteous, and above that; HONEST. I'm an engineer with a background in electronics. When my furnace failed I downloaded the schematics for my unit, broke out my tools, and started troubleshooting the issue. My conclusion was that the main blower had failed, and I relayed that information to Christopher. After he took the time to carefully diagnose the issue he found that it wasn't the motor, but a different component that cost half as much to replace. read more

Do not hire Smart Heating and Air Conditioning!!!!! Their tech named "Benny" lied! He said the A/C condenser was not working, the freon was empty and that the run capacitor wiring was put on wrong and had fried the unit. He told me that getting a replacement was the only way to go and that it would be 8-12,000 dollars. So I decided to get a second opinion "Eric - from Integrity Air" and the guy got it up and running in 10 min. He quickly notice that "Benny" had unplugged some cables (basically sabotaged the unit) The repair guy also said all the things that your guy "Benny" said were not true. I am going to let everyone know what has happened!!!! read more

Great service! Easy to talk to. They understand the urgency of our repair request. I txted Susie after work hours and got a response quickly. She's able to arrange a tech to come the next morning. Their tech Emilio, Benny and some others were all nice and great. read more

I recently changed out my old A/C unit which was about 20 yrs old. I did my research and found Smart Heating and Air Conditioning [SHAC) to be the best! They are not the cheapest, but they are the best value. Finding the cheapest, especially when it comes to A/C units [which you are going to use for 20 yrs] do you really want to put the cheapest? You want the best value and the equipment that will last. SHAC carries the best equipment. Their service is top notch. The owner, Mike, came to oversee the installation to ensure everything went smoothly. Mike even took care of me in refill the old unit with freon...what! Who does that? After the installation had an issue on a Sunday later afternoon. SHAC sent out a tech Sunday night and took are of it. Very satisfied, they were profession from start to finish. Highly recommend SHAC! read more

Everything was really good! Zach, the technician, showed up right on time at the beginning of the reserved time slot. He was clean, polite and knowledgeable. He checked my AC unit, cleaned it up and fixed the broken part in less than an hour. Great service overall! I'll definitely will get back to them for further HVAC maintenance! read more

Mark and Mike helped my family design and install a brand new dual zone heat pump system for our home. From start to finish, they provided a competitive and fair quote, clear communication, and flexed their expertise with the quality of work performed. Mark came by to inspect our system and provide a quote. He was was incredibly knowledgeable and took the time to explain the system's layout, limitations, and what would work best for my home. No upselling, no pressure--just honest advice tailored to my needs. Mike, the owner, came out twice to my house to ensure that what we planned out was right for me and my family. He even convinced us to take the smaller quote of his to give our house the most efficient cost effective solution. He prioritized what was best for us over upselling us an unnecessary system. Benny and Emilio, and the rest of the fellas did a fantastic job. They moved my heat pump to an additional platform, rebalanced my vents, and even created an additional register that was previously blocked over. The work looks super clean and went the extra mile to make sure everything worked properly. Bottom line, if you want honest contractors that prioritize your family's comfort, Mike and the boys are the guys to call. read more

Got stuck with no cooling on July 3rd evening! It was going to be the hottest next few days of the season and had no hope to get any service it being July 4th. Was pleasantly surprised with the quick response of smart heating & ac team as well as being able to speak with a person (& not a BOT) to schedule an appointment the very next day. Quick follow through on July 5th and Benny Cruz was within the service time window. Friendly, smiling all through the heat, he quickly identified and rectified the issue. Seemed knowledgeable and gave good advice. Thanks to smart team! read more

I have a service contract with Smart Heating and Air Conditioning and they have always been efficient, knowledgable and professional! Zack was the most recent service engineer that checked the AC units. He did a great job in repairing and maintaining both of my units. They also serviced both my furnaces this last Autumn, and my system is 26 years old! I would highly recommend this locally owned firm for all your heating and air conditioning needs. They are honest and reliable! read more

I put in a request through Yelp for quotes for AC Maintenance and they reached out to me almost immediately. I ended up just calling to ask questions and Raquel who answered the phone was wonderful answering all of my questions about every different kind of services I might need throughout the year. They were able to be at my house within a couple of hours to do my requested maintenance! The technician London was respectful of my house and incredibly knowledgeable about his trade. He took the time to do a thorough inspection and sat down to explain each finding. He answered all of my questions and explained what work might be needed down the road or what things to keep an eye on to keep my HVAC in optimal condition. I will be telling all my friends and neighbors about this company. Highly recommend! read more

I had such an amazing experience with this company. The company contacted me promptly and gave me updates on the arrival of the technician through text message. They even sent a photo of the technician so I would know who to look for. Christpher Wilson was an excellent technician. He patiently examined the issue we were having and fixed it with care. He was thorough and very knowledgeable. read more

We had our second experience with Smart Heating and Air Conditioning, and we were just as pleased this time as the first. Juan came out early for his appointment (after a phone call to get approval), and then gave our air conditioning system a complete review. Although, our system is now 20 years old, it is still functioning well, and Juan said that it is in the best condition he has seen for a system this old. However, we decided to have some of the electrical connections replace now to avoid any "surprises" in the future. Juan is knowledgeable, efficient, friendly, and completed the job quickly. I can not recommend Smart Heating and Air Conditioning highly enough, and we would not consider going anywhere else for our HVAC needs. read more

They have been such a WONDERFUL company to work with. Mike and his crews are very professional, courteous and knowlegeable. I will be definitely calling them back when I have a bigger HVAC related project for them. read more

Yes I absolutely recommend them. I actually called my home warranty originally but they connected me with a vendor that has 2 stars and never called me for an appointment so I did my research and found Smart Heating and AC! They gave an appointment the next day (thank goodness). I had an amazing experience with them! I will definitely recommend them to all my clients! read more

I'm warm again! I got fast service and I'm grateful. Emilio was an absolute treasure. He was polite sweet and even vacuumed the inside and helped me reattach the filters. The price was great too. I only needed a tuneup. Thank you so much and happy holidays. read more

Our experience with Smart Heating and Air Conditioning ,overall, was a great one! Starting with Mark, who got us started to the working crew Emilio, Benny, Josh and Jose, all worked with much diligence and efficiency which made things very smooth from beginning to the end. We, also, appreciated Mike for finalizing everything and the job was completed with satisfaction. I will definitely recommend this company to my friends and family. read more

Mike was nothing short of incredible! He not only explained everything and was very clean and respectful of my home, but he didn't try to up sell me or take advantage of the fact that it was the week of thanksgiving and I was hosting at my home. I appreciate his cleanliness and attention to detail. You can tell that he is very knowledgeable and has a lot of experience in this HVAC industry. I am the type of person to do a lot of research because I like to know about things, especially that has to do with comfort, health, and safety of my family, and he blew me away with information. I've already suggested him to all of my friends, family, and coworkers for anything they need with their system in their homes. I know that if I move to a new home soon, I'll be calling Mike at Smart Heating and air to check out that system before I buy anything. Thanks again, Mike. You're service is worth any kind of high praise I can offer read more

This review is long overdue. Back on August 8, 2023, my A/C went out. After looking online at different HVAC companies I chose Smart Heating and Air Conditioning and I am so pleased that I did. I called the office and spoke with Jen on the 8th and Sam came out to my home on the 9th for a complete inspection of my A/C and furnace. Unfortunately, they were both quite old and could not be repaired but needed to be replaced. The heater actually had cracks in the out take pipes and was actually quite dangerous and since it was in my attic i never would have seen the problems. The crew was out the following day (Angel, Benny and Miguel) and completed the job that day. The system passed both the intermediary inspection and the city of Concord inspection the first time. I have nothing but good things to say about Smart. Their communication was amazing sending texts with photos of who was coming and when and they arrived on time and were all so courteous, knowledgeable, respectful of my property and left everything clean when they were gone. Thank you Smart HVAC. I now have a quieter and more efficient system. Kathy read more

Tuesday morning our furnace stopped working. I called Smart Heating and Air Conditioning around lunch time after reading all of the good reviews on Yelp. First thing Wednesday morning Frank was at my door. Within a few minutes he had figured out what the problem was and got to work on the repairs. He got my furnace back running as good as new. When I went up in the attic to take a look after he left, I was floored. My furnace is cleaner than the builder left it when I bought the house. It honestly looks better than new and it is running great. Frank clearly takes pride in his work. When it was all said and done, my furnace was fixed in less than 24 hours from when I called them. That is pretty darn good service. read more

First, I cannot rave enough about the customer service . They are very responsive and answered our call at 9 pm last summer during a heat wave. They text when they are on the way to your home. They're quick, efficient and respectful of you & your home. Second, we now needed to replace our current system that was 15 yrs old & had never worked properly for the size and layout of our home. Sam had several suggestions of what we could do to remedy those issues. Their team was so efficient and caring. The new heating/cooling system is amazing. I felt like I was in a new home. No more hot or cold spots. The air flow has improved 100% with their suggestions of how to fix that issue. A regular cleaning & maintenance plan is easy to set up (necessary) and is painless & reasonable. I cannot say enough good things about Mike and his crew. We are so happy with the results! read more

My AC went off and I had to have the whole outdoor unit changed. I got a quote and a quick replacement date with Smart Heating and Air Conditioning. Mike, the owner, came with his crew and despite the challenges did a great job of installing new unit. Next day, Benny came to finish the wiring and gave me a tutorial on how to use the Nest and the app, to make sure all works as it should. Their customer service was great as well! Will work with the company if I needed any other repairs regarding heating and AC. read more

We had an old HVAC unit outside of our house that was over 25yrs old and wanted to replace before summer. Chris came out to the house to give us an estimate that was very competitive and he didn't push us on doing more than we needed. Felt very comfortable doing business with him, no BS, explained things well to us, gave us great observation on things he saw with our old insulation while inspecting the cooling and heating ducts. We felt we could trust them and felt no pressure at all. Then for the install after we approved the estimate was great! The three technicians Jose, Emillio, and Josh were wonderful. They were vey gracious, answered all of our questions, were super friendly, and hard working. They completed it by early afternoon and that included having the external condenser moved to the other side of the house from where the old one was. Install looks great and well put together. I highly recommend this company! read more
